Can weight gain be a sign of thyroid problems?

Yes, weight gain can be a symptom of hypothyroidism, a condition where the thyroid produces insufficient hormones. Since the thyroid regulates metabolism, lower levels of T3 and T4 can slow down the body's metabolic rate, leading to weight gain. Other symptoms of hypothyroidism include fatigue, dry skin, and cold intolerance. If you experience unexplained weight gain, your healthcare provider may order a thyroid function test (TFT) to evaluate your TSH, T3, and T4 levels. Proper diagnosis and treatment with thyroid hormone replacement can help manage weight and other symptoms.
