Hypothyroidism

Hypothyroidism is a condition in which the thyroid gland, located in the front of the neck, does not produce enough thyroid hormone to meet the body's needs, causing many of the body's metabolic processes to slow down. Thyroid hormone regulates metabolism throughout nearly every organ system, so its deficiency produces a wide range of symptoms affecting energy levels, weight, temperature regulation, mood, and more. In India and globally, the most common cause is an autoimmune condition called Hashimoto's thyroiditis, in which the immune system gradually damages the thyroid gland, alongside iodine deficiency, which remains relevant in certain regions despite widespread salt iodisation programmes. Hypothyroidism often develops slowly, and its symptoms can be subtle and easily attributed to other causes, meaning the condition frequently goes undiagnosed for some time. Diagnosis through a simple blood test and daily thyroid hormone replacement therapy generally provide excellent, long-lasting symptom control.

The most common symptoms include: Fatigue and low energy; unexplained weight gain; cold intolerance; dry skin and hair. Early recognition is key to prompt diagnosis and effective treatment.

No, Hypothyroidism is not contagious. It cannot spread through casual contact. However, certain risk factors and genetic predispositions may increase susceptibility.

Treatment options include: Treatment involves daily oral thyroid hormone replacement medication; typically levothyroxine; which restores normal hormone levels and resolves symptoms in the majority of patients when dosed appropriately. Regular blood testing is used to monitor thyroid hormone levels and adjust the medication dose as needed. Treatment should always be guided by a qualified Endocrinology & Diabetology specialist. Do not self-medicate.

While Hypothyroidism cannot always be fully prevented, several measures can reduce risk: Ensuring adequate dietary iodine intake through iodised salt; regular thyroid function screening for those with a family history of thyroid disease; prompt evaluation of persistent fatigue or other suggestive symptoms.

Consult a Endocrinology & Diabetology specialist if symptoms persist for more than a few days, worsen despite home care, or significantly affect your daily activities. Early diagnosis leads to better outcomes.
