Underactive thyroid
Underactive thyroid, also known as hypothyroidism, is a condition where the thyroid gland does not produce enough thyroid hormones. This condition can affect the body's metabolic processes and can lead to a variety of symptoms.
Symptoms[edit | edit source]
Symptoms of an underactive thyroid can vary widely from person to person. They may include:
- Fatigue
- Weight gain
- Depression
- Sensitivity to cold
- Dry skin
- Hair loss
- Constipation
- Slow heart rate
- Muscle weakness
Causes[edit | edit source]
The most common cause of an underactive thyroid is Hashimoto's thyroiditis, an autoimmune disease where the body's immune system attacks the thyroid gland. Other causes can include:
- Thyroid surgery
- Radiation therapy
- Certain medications
- Pituitary gland disorders
- Pregnancy
Diagnosis[edit | edit source]
Diagnosis of an underactive thyroid typically involves a blood test to measure levels of thyroid-stimulating hormone (TSH) and thyroxine (T4). High levels of TSH and low levels of T4 usually indicate hypothyroidism.
Treatment[edit | edit source]
Treatment for an underactive thyroid usually involves daily use of the synthetic thyroid hormone levothyroxine. This medication restores adequate hormone levels and reverses the symptoms of hypothyroidism.
