Hypothyroidism (Underactive Thyroid): Everything You Need to Know
Hypothyroidism, commonly referred to as an underactive thyroid, occurs when the thyroid gland doesn't produce sufficient levels of thyroid hormones. This condition can lead to symptoms such as unexplained weight gain, fatigue, cold sensitivity, and dry skin. While the symptoms may feel overwhelming, effective treatments, including medications and lifestyle adjustments, can significantly improve your quality of life.
In this guide, you'll discover the causes, symptoms, treatment options, and essential tips for managing hypothyroidism effectively.
What is Hypothyroidism?
Hypothyroidism, or an underactive thyroid, occurs when your body doesn’t produce enough thyroid hormones. The thyroid is a small, butterfly-shaped gland located at the front of your windpipe. It plays a crucial role in regulating and using energy, making it essential for your body’s natural functions.
Thyroid hormones influence vital processes like how your heart beats and how your digestive system operates. When hormone levels are low, these functions begin to slow down, which can lead to symptoms like fatigue, weight gain, and cold sensitivity.
While hypothyroidism can affect anyone, it’s more common in women than men, particularly those over the age of 60. It’s often detected through a routine blood test or after symptoms appear. An early, mild form of the condition is known as subclinical hypothyroidism.
If you’ve recently been diagnosed with hypothyroidism, take comfort in knowing that treatment is typically simple, safe, and effective. Most therapies involve replacing the missing hormones with artificial ones, helping your body return to normal function and improving your quality of life.
Hypothyroidism vs. Hyperthyroidism: What’s the Difference?
While hypothyroidism and hyperthyroidism both involve the thyroid gland, their effects on the body are completely opposite.
In hypothyroidism (underactive thyroid), the thyroid doesn’t produce enough thyroid hormones, slowing down your body’s functions. Conversely, hyperthyroidism, or an overactive thyroid, occurs when the thyroid gland produces too much thyroid hormone. This excess hormone speeds up various processes in your body, leading to symptoms like:
- Faster heart rate
- Unintended weight loss
- Difficulty sleeping
Although hyperthyroidism is less common than hypothyroidism, it still affects about 1% of people aged 12 and older in the United States, according to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). Similar to hypothyroidism, hyperthyroidism is more prevalent in women and individuals over the age of 60.
Treatment options for hyperthyroidism include medications, radioiodine therapy, and, in some cases, surgery to manage hormone levels and alleviate symptoms.
How Common is Hypothyroidism? Prevalence, Risk Factors, and Key Statistics
Hypothyroidism is a relatively common condition, particularly as people age. According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), nearly 5% of individuals aged 12 and older in the United States have hypothyroidism.
The likelihood of developing hypothyroidism increases with age, making it more prevalent in individuals over 60 years old. Additionally, women are significantly more affected than men. In fact, approximately 1 in 8 women will develop a thyroid condition in their lifetime.
What Are the Signs and Symptoms of Hypothyroidism? A Comprehensive Guide
The symptoms of hypothyroidism can vary widely between individuals, making the condition challenging to identify in its early stages. The severity of the condition plays a role in when symptoms appear and how noticeable they become.
Early signs of hypothyroidism often include fatigue and weight gain—two changes that can be easily overlooked, as they are common with aging. Many people may not realize their symptoms are linked to their thyroid until more noticeable changes develop, such as scaly, rough, and dry skin or brittle nails.
Common Symptoms of Hypothyroidism:
Here are some of the most frequently reported signs of hypothyroidism:
- Fatigue
- Unexplained weight gain
- Depression or low mood
- Constipation
- Feeling cold
- Decreased sweating
- Slowed heart rate
- Elevated blood cholesterol levels
- Dry skin
- Dry, thinning hair
- Memory issues or "brain fog"
- Muscle weakness
- Muscle aches, stiffness, or tenderness
- Joint pain and stiffness
For many, these symptoms develop gradually over years. As the thyroid gland slows its production of hormones, the signs of hypothyroidism often become more apparent. However, several of these symptoms, like fatigue and joint pain, are also common with aging in general.
If you notice any of these symptoms or suspect a thyroid issue, it’s important to consult your doctor. A simple blood test can confirm whether you have hypothyroidism and help guide your treatment plan.
Hypothyroidism Symptoms in Adults: Men, Women, and During Pregnancy
While the common symptoms of hypothyroidism affect both men and women, there are certain symptoms unique to each gender. Understanding these differences can help with early identification and effective treatment.
Symptoms in Men
According to research, men with hypothyroidism may experience erectile dysfunction in addition to the standard symptoms of fatigue, weight gain, and depression.
Symptoms in Women
For women, hypothyroidism can lead to unique challenges, including:
- Fertility difficulties
- Irregular or heavy menstrual periods
- Complications during pregnancy, such as anemia
Hypothyroidism and Pregnancy
It’s also possible to develop hypothyroidism during pregnancy. Symptoms typically mirror those of other cases of hypothyroidism, such as fatigue, weight gain, and cold sensitivity. Addressing hypothyroidism during pregnancy is critical, as it can impact both maternal and fetal health.
Hypothyroidism in Young People: Children, Teenagers, and Infants
Although hypothyroidism is less common in younger individuals, it can still occur and may present unique challenges depending on the age group. Identifying symptoms early is key to ensuring proper treatment and healthy development.

Congenital Hypothyroidism in Infants
Babies can be born with congenital hypothyroidism, a condition where the thyroid gland does not function properly from birth. While some infants may show no noticeable symptoms, others may experience:
- Excessive sleeping
- Constipation
- Feeding difficulties
- Delayed growth and development (if left untreated)
Early screening and treatment are critical to preventing long-term developmental delays in infants with hypothyroidism.
Severe Hypothyroidism Symptoms: What to Watch For
If hypothyroidism goes untreated, it can progress to more severe symptoms that significantly impact your health and quality of life. Recognizing these signs early can help prevent serious complications.
Symptoms of Severe Hypothyroidism
Untreated hypothyroidism may lead to:
- Puffy, sensitive face
- Hoarseness
- Anemia
- Hearing loss
Myxedema Coma: A Rare but Serious Complication
In rare cases, untreated hypothyroidism can result in a life-threatening condition called myxedema coma, which requires emergency medical care. Despite its name, myxedema coma does not always involve being in an actual coma. Symptoms of myxedema coma include:
- Extreme fatigue
- Hypothermia (dangerously low body temperature)
- Low blood pressure
- Low heart rate
Myxedema coma is a medical emergency and requires immediate treatment to avoid life-threatening complications. If you or someone you know experiences these symptoms, seek emergency care immediately.
What Causes Hypothyroidism? Common and Rare Triggers
Understanding the causes of hypothyroidism is crucial for early diagnosis and effective treatment. While some causes are common, others are less frequently seen but still important to recognize.
Common Causes of Hypothyroidism

-
Pituitary Disorders
Conditions affecting the pituitary gland may reduce its ability to signal the thyroid to produce hormones. -
Congenital Hypothyroidism
Babies can be born with an underdeveloped or malfunctioning thyroid gland. -
Pregnancy
Hormonal changes during pregnancy may lead to hypothyroidism, a condition known as postpartum thyroiditis. -
De Quervain Thyroiditis
A rare inflammation of the thyroid, often following a viral infection, which can temporarily reduce thyroid hormone levels.
Recognizing the cause of hypothyroidism is essential for selecting the right treatment plan. If you suspect thyroid issues, consult a healthcare professional for proper evaluation and testing.
Hashimoto’s Thyroiditis: The Leading Cause of Hypothyroidism
Your immune system is designed to defend your body against harmful bacteria and viruses. However, in some cases, your immune system mistakenly targets healthy cells, leading to an autoimmune response. When this response is not properly regulated, it can cause your immune system to attack healthy tissues, resulting in serious medical conditions like hypothyroidism.
What is Hashimoto’s Thyroiditis?
Hashimoto’s thyroiditis is a chronic autoimmune disorder and the most common cause of hypothyroidism in the United States, according to the National Center for Biotechnology Information (NCBI). In this condition, your immune system attacks and damages the thyroid gland, reducing its ability to produce thyroid hormones.
Who is at Risk?
- Middle-aged women are most commonly affected, but the condition can also occur in men and children.
- Family history plays a significant role. If a close relative has been diagnosed with Hashimoto’s thyroiditis, your risk of developing the condition increases.
Recognizing the symptoms of Hashimoto’s thyroiditis and seeking medical evaluation is essential for early treatment, which can prevent further thyroid damage and manage the condition effectively.
Radioactive Iodine Treatment for Hyperthyroidism: How It Works and Its Effects
If your thyroid gland produces too much thyroid hormone, you may have a condition called hyperthyroidism. The goal of treatment is to reduce and regulate thyroid hormone production, restoring balance to your body’s functions.
What is Radioactive Iodine Treatment?
A standard treatment for hyperthyroidism involves the use of radioactive iodine. This therapy works by:
- Destroying overactive thyroid cells, reducing the gland's ability to produce excessive hormones.
- Gradually leading to lower levels of thyroid hormones.
Long-Term Effects
While this treatment is highly effective, it often results in the thyroid producing insufficient hormones after treatment, leading to hypothyroidism. In such cases, lifelong thyroid hormone replacement therapy may be required to maintain normal hormone levels.
Radioactive iodine treatment is widely used and generally safe when administered under medical supervision. If you have concerns about the treatment, consult your healthcare provider to discuss the risks and benefits.
Surgical Removal of Your Thyroid: What to Expect and Its Impact on Hormone Levels
Surgical removal of the thyroid gland—a procedure known as a thyroidectomy—is sometimes necessary to treat severe thyroid conditions, such as thyroid cancer, large goiters, or hyperthyroidism.
What Happens After Thyroid Removal?
-
Complete Thyroid Removal:
If your entire thyroid gland is removed, you will develop hypothyroidism because your body can no longer produce thyroid hormones. Lifelong thyroid medication will be required to replace the missing hormones and regulate your body's functions. -
Partial Thyroid Removal:
If only a portion of the thyroid is removed, the remaining part may still produce enough hormones to meet your body's needs. Regular blood tests will determine whether you require thyroid hormone medication and, if so, the appropriate dosage.
Key Takeaway
Thyroid surgery is a highly effective treatment for certain thyroid conditions. However, it’s important to work closely with your healthcare provider to manage hormone levels and maintain a healthy balance after the procedure.
Radiation Therapy and Hypothyroidism: Understanding the Connection
Radiation therapy is a common treatment for cancers such as head and neck cancer, lymphoma, or leukemia. While effective in targeting cancer cells, this therapy can sometimes affect the thyroid gland.
How Radiation Therapy Affects the Thyroid
Radiation exposure during treatment can:
- Damage thyroid cells, reducing their ability to produce hormones.
- Lead to slowed or halted thyroid hormone production, resulting in hypothyroidism over time.
Key Takeaway
If you’ve undergone radiation therapy, it’s important to monitor your thyroid function through regular blood tests. Early detection of thyroid issues allows for prompt treatment, helping to prevent long-term complications.
Medications That Can Cause Hypothyroidism: What You Need to Know

Pituitary Disorders and Hypothyroidism: Understanding Secondary Hypothyroidism
Hypothyroidism doesn’t always originate from the thyroid gland itself. In some cases, the condition may result from issues with the pituitary gland, a small but crucial gland located in the brain. The pituitary gland produces hormones that regulate various body functions, including the thyroid gland.
Causes of Pituitary Disorders Leading to Hypothyroidism
Pituitary disorders that may result in hypothyroidism include:
-
Pituitary Tumors
Growths in the pituitary gland can disrupt hormone production and signaling. -
Medications
Drugs such as dopamine and opioids can affect pituitary function. -
Radiation Therapy
Radiation around the brain can damage the pituitary gland, leading to hormone imbalances. -
Sheehan Syndrome
A rare condition caused by severe blood loss during childbirth, which damages the pituitary gland.
Secondary Hypothyroidism vs. Primary Hypothyroidism
This type of hypothyroidism is called secondary hypothyroidism because the thyroid gland itself functions normally. The issue lies in the pituitary gland’s inability to signal the thyroid to produce hormones. Secondary hypothyroidism is less common than primary hypothyroidism, which results from a direct problem with the thyroid gland.
Key Takeaway
If you suspect pituitary issues or experience symptoms of hypothyroidism, consult your doctor. Diagnosing and managing secondary hypothyroidism often involves addressing the underlying pituitary disorder.
Congenital Hypothyroidism: Causes, Symptoms, and Early Treatment
Congenital hypothyroidism refers to hypothyroidism that is present at birth. It affects approximately 1 in 2,000 to 1 in 4,000 newborns, and is twice as common in females, according to MedlinePlus.
Causes of Congenital Hypothyroidism
This condition occurs when:
- The thyroid gland develops abnormally or is absent.
- Genetics or iodine deficiency interfere with thyroid gland formation and function.
Symptoms of Congenital Hypothyroidism
While some newborns may show no visible symptoms, others may experience:
- Low activity levels (appearing lethargic)
- Difficulty feeding
Untreated congenital hypothyroidism can lead to delayed growth and mental development, making early detection and treatment essential.
Early Detection and Treatment
In the United States, hospitals routinely test newborns for congenital hypothyroidism through screening programs. Early treatment, usually involving thyroid hormone replacement, is crucial for preventing developmental delays and ensuring healthy growth.
Pregnancy and Hypothyroidism: Understanding Postpartum Thyroiditis
Postpartum thyroiditis is a thyroid condition that affects approximately 5 to 10 percent of pregnant individuals, typically developing several months after pregnancy, according to NCBI and MedlinePlus. While some cases resolve without the need for treatment, others may progress to permanent hypothyroidism.
Risk Factors for Postpartum Thyroiditis
Certain factors can increase the likelihood of developing postpartum thyroiditis:
-
History of Postpartum Thyroiditis
Individuals who have experienced this condition in a previous pregnancy are at higher risk. -
Thyroid Peroxidase Antibodies
The presence of antibodies to thyroid peroxidase in the blood, which is an indicator of autoimmune thyroid issues. -
Type 1 Diabetes
Those with type 1 diabetes are more susceptible to postpartum thyroiditis due to an increased likelihood of autoimmune conditions.
What You Should Know
Postpartum thyroiditis may cause temporary hyperthyroidism (overactive thyroid) followed by hypothyroidism. Regular blood tests can help monitor thyroid hormone levels during and after pregnancy. If you’re experiencing symptoms or have a higher risk, consult your healthcare provider for evaluation and guidance.
De Quervain Thyroiditis: Causes, Symptoms, and Recovery
De Quervain thyroiditis, also known as subacute granulomatous thyroiditis, is a rare thyroid condition caused by an upper respiratory infection that damages thyroid cells. It is more common in women and tends to occur during the summer and fall months, according to NCBI.
Symptoms of De Quervain Thyroiditis
Common symptoms include:
- Pain in the neck, jaw, or throat
- Enlarged and tender thyroid gland
- Fever
- Fatigue
- Body pain
How the Condition Progresses
De Quervain thyroiditis typically causes temporary hyperthyroidism (overactive thyroid), which may later progress to hypothyroidism (underactive thyroid). The condition usually lasts 2 to 8 weeks, after which thyroid function often returns to normal. However, in some cases, hypothyroidism may become permanent, requiring long-term treatment.
Key Takeaway
If you experience symptoms like neck pain or tenderness, consult your healthcare provider. Early diagnosis and treatment can help manage symptoms and minimize the risk of long-term thyroid complications.

- Slower heart rate
- Ask about symptoms like fatigue, constipation, and feeling cold.
- Inquire about your family history of thyroid conditions, as this can increase your risk.
Sharing all symptoms and family history during this evaluation is crucial for an accurate diagnosis.
2. Blood Tests
Blood tests are the most reliable way to confirm a diagnosis of hypothyroidism. Common blood tests include:
- Thyroid-Stimulating Hormone (TSH) Test
- Measures the amount of TSH your pituitary gland produces.
- High TSH levels indicate your thyroid isn’t producing enough hormones, pointing to hypothyroidism.
- Low TSH levels may suggest hyperthyroidism, where excessive thyroid hormones are being produced.
- Thyroxine (T4) Test
- T4 is a hormone directly produced by the thyroid gland.
- Low T4 levels combined with high TSH levels confirm hypothyroidism.
- In subclinical hypothyroidism, T4 levels may remain normal, but TSH levels will be elevated.
- Triiodothyronine (T3) Test
- This test may be performed if T4 levels are normal but symptoms persist.
- Low T3 levels could indicate hypothyroidism, although T3 levels may remain normal in subclinical hypothyroidism.
- Thyroid Antibody Tests
- These tests detect antibodies in your blood to diagnose autoimmune conditions like Hashimoto’s thyroiditis, the most common cause of hypothyroidism.
Additional Considerations
Since thyroid disorders can vary in severity and presentation, your doctor may recommend other thyroid function tests to fully evaluate your condition. Regular monitoring is also important for ongoing management.

Shared and Distinct Symptoms
While hypothyroidism and depression share several symptoms, they also have distinct characteristics:
- Shared Symptoms: Fatigue, weight gain, and a low mood are common in both conditions.
- Hypothyroidism-Specific Symptoms: Dry skin, constipation, and hair loss are unique to hypothyroidism.
- Depression-Specific Symptoms: These may not include physical symptoms like dry skin or hair loss, which are typical of hypothyroidism.
Diagnosing the Link
- Depression Diagnosis: Typically based on symptoms and medical history.
-
Hypothyroidism Diagnosis: Confirmed through a physical exam and blood tests that check thyroid hormone and TSH levels.
If you experience overlapping symptoms, your doctor may test for underactive thyroid function to determine whether hypothyroidism is contributing to your depression.
Treating Hypothyroidism-Related Depression
If your depression is directly caused by hypothyroidism, addressing the thyroid disorder with treatment—like levothyroxine—may resolve depressive symptoms.
- If depression persists after thyroid levels are corrected, your doctor may prescribe antidepressant medications alongside thyroid treatments.
- Both conditions require careful dose adjustments to achieve effective symptom management.
Key Takeaway
The connection between hypothyroidism and depression highlights the importance of thorough diagnosis. If you’re experiencing symptoms of depression, consult your doctor about testing your thyroid function. Treating hypothyroidism may improve not only your physical health but also your mental well-being.
What’s the Connection Between Hypothyroidism and Anxiety?
While hypothyroidism is commonly linked to depression, emerging research suggests it may also be associated with anxiety. Understanding this potential connection can help guide more comprehensive evaluations and treatments for people with hypothyroidism.
Hypothyroidism and Anxiety: What the Research Says
A 2016 study evaluated 100 individuals aged 18 to 45 with a history of hypothyroidism. Using an anxiety questionnaire, researchers found that:
- Around 63% of participants met the criteria for some form of anxiety.
- This suggests a potential link between hypothyroidism and anxiety, though further larger-scale studies are needed to confirm the connection.
What Does This Mean for You?
The overlap of symptoms between hypothyroidism and anxiety can complicate diagnosis. For example:
- Fatigue, difficulty concentrating, and restlessness can be symptoms of both conditions.
- Other physical symptoms of hypothyroidism, such as dry skin, weight gain, or constipation, are not typically associated with anxiety disorders.
Why Communication with Your Doctor Matters
If you’re being evaluated for hypothyroidism or a mental health condition, it’s important to:
- Discuss all your symptoms with your doctor, including any feelings of anxiety.
- Allow your healthcare provider to consider the possibility of anxiety as part of your thyroid condition.
- Work together to create a treatment plan that addresses both physical and mental health needs.
Key Takeaway
While the connection between hypothyroidism and anxiety is still being studied, addressing both conditions as part of your overall health is essential. Open communication with your healthcare provider ensures a more accurate diagnosis and tailored treatment plan.
What’s the Effect of Hypothyroidism on Pregnancy?
People with thyroid problems, including hypothyroidism, can and often do have healthy pregnancies. However, low thyroid function or unmanaged hypothyroidism during pregnancy can pose specific challenges. Understanding these risks and taking proactive steps can help ensure the health of both the mother and baby.
Potential Complications of Hypothyroidism During Pregnancy
If hypothyroidism is not well-managed, it can increase the risk of:
- Anemia
- Miscarriage
- Preeclampsia (a condition characterized by high blood pressure and organ damage)
- Stillbirth
- Low birth weight
- Brain development problems in the baby
- Birth defects
Steps to Manage Hypothyroidism During Pregnancy
To reduce these risks, it’s important to take the following steps:
- Talk with Your Doctor About Testing
- You can develop hypothyroidism during pregnancy, even if you’ve never had thyroid issues before.
- Many doctors routinely monitor thyroid hormone levels during pregnancy to detect and address low levels early.
- Postpartum thyroiditis can develop after childbirth, even in individuals with no prior history of thyroid issues. According to the American Thyroid Association, this condition often resolves within 12 to 18 months, though about 20% of individuals may require long-term therapy.
- Stay Up to Date with Your Medication
- Continue taking thyroid medication as prescribed by your doctor.
- Regular blood tests will help your doctor adjust your medication dosage as needed to ensure both you and your baby receive adequate thyroid hormones for healthy brain and nervous system development.
- Eat a Nutrient-Dense Diet
- Your body needs more nutrients during pregnancy, including iodine, which is essential for thyroid hormone production.
- Aim for 250 micrograms of iodine per day, as recommended by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).
- Iodine can be found in foods like iodized salt, dairy products, and seafood.
- Always consult your doctor before starting any new supplements.
Key Takeaway
Hypothyroidism can increase the risk of complications during pregnancy, but with regular monitoring, medication adjustments, and a balanced diet, most people with thyroid problems can have healthy pregnancies. Open communication with your healthcare provider is essential to managing thyroid function effectively during this important time.
What’s the Connection Between Hypothyroidism and Weight Gain?
Your thyroid gland plays a crucial role in regulating your body's functions, including metabolism, organ performance, and temperature control. When your thyroid doesn’t produce enough hormones, these processes slow down, which can lead to weight gain.
How Hypothyroidism Affects Weight
When thyroid function is low, your basal metabolic rate (BMR)—the amount of energy your body uses at rest—also decreases. This means your body burns fewer calories, leading to weight gain.
- The amount of weight gained typically depends on the severity of the condition.
- According to the American Thyroid Association, most people with hypothyroidism gain 5 to 10 pounds, with more severe cases potentially leading to greater weight gain.
Weight Loss After Treatment
Proper treatment of hypothyroidism, such as with levothyroxine, may help you lose the weight gained during untreated thyroid dysfunction. However:
- Weight loss isn’t always guaranteed.
- Symptoms of hypothyroidism, including weight gain, often develop gradually and may not be solely caused by low thyroid hormone levels.
What If Weight Doesn’t Change After Treatment?
If your weight remains stable after treatment, it doesn’t mean your hypothyroidism isn’t being properly managed. Instead:
- Weight gain may be influenced by lifestyle factors or other underlying conditions, rather than solely by hypothyroidism.
- Focus on a healthy diet, regular exercise, and stress management to support your overall health.
Key Takeaway
Hypothyroidism can slow your metabolism, leading to moderate weight gain. While treatment may help reverse this, other factors like lifestyle and overall health also play a role. For the best results, maintain open communication with your doctor and focus on holistic health strategies.
What’s the Connection Between Hypothyroidism and Weight Loss?
Treating hypothyroidism can restore your thyroid hormone levels to normal, which may help you lose any weight gained due to the condition. However, weight loss after treatment isn’t guaranteed and may require additional lifestyle changes to achieve your goals.
How Treatment Affects Weight Loss
Once your thyroid levels are properly managed through treatment, such as levothyroxine, your metabolism and ability to regulate weight return to normal. This means:
- Any weight gained directly due to low thyroid hormone levels may naturally decrease.
- The amount of weight lost depends on factors like how long the condition went untreated and other lifestyle influences.
What If Weight Doesn’t Change After Treatment?
If you’ve been treated for hypothyroidism but haven’t experienced weight loss:
- Weight gained prior to treatment may not have been solely due to hypothyroidism.
- Factors like diet, exercise habits, and overall health may play a bigger role in maintaining or losing weight after treatment.
Tips for Managing Weight with Hypothyroidism
Even if weight loss isn’t immediate, you can still work toward your goals with a healthy lifestyle:
-
Consult Professionals:
Work with a doctor, registered dietitian, or personal trainer to create a plan tailored to your needs. -
Focus on Balanced Nutrition:
Eat a diet rich in whole foods, including fruits, vegetables, lean proteins, and healthy fats. -
Incorporate Exercise:
Regular physical activity, including a mix of cardio and strength training, can help boost your metabolism.
Key Takeaway
While treating hypothyroidism can help restore normal weight regulation, weight loss may require additional effort through healthy eating and exercise. Collaborating with healthcare professionals can support your journey toward achieving and maintaining a moderate weight.
