Hypothyroidism

Hypothyroidism is a common endocrine disorder in which the thyroid gland does not produce enough thyroid hormones to meet the body’s needs. These hormones regulate metabolism, energy production, temperature, heart function, and many other essential processes. The condition may develop gradually and can affect people of all ages.

Common causes include autoimmune thyroid disease, particularly Hashimoto’s thyroiditis, iodine deficiency, certain medications, thyroid surgery, radiation treatment, and disorders affecting the pituitary gland. Symptoms often develop slowly and may include persistent tiredness, weight gain, sensitivity to cold, dry skin, constipation, muscle weakness, hair thinning, low mood, and difficulty concentrating. Some people may also experience a slow heart rate or menstrual irregularities.
Diagnosis usually involves blood tests measuring thyroid-stimulating hormone(TSH) and free thyroxine (T4). Additional tests may help identify the underlying cause when necessary. Treatment generally involves thyroid hormone replacement with levothyroxine, which restores hormone levels and helps relieve symptoms. Dosage is individualized according to laboratory results, age, health status, and other factors.

With appropriate diagnosis and regular monitoring, hypothyroidism can usually be managed effectively. Consistent medication use and periodic thyroid function testing are important for maintaining stable hormone levels and supporting overall health.
