Is weight gain inevitable with thyroid diseases?

Thyroid hormones play a key role in weight control, and both underactive and overactive thyroid function can trigger weight changes by disrupting metabolic balance, according to the article. In hypothyroidism, where hormone production falls, weight gain can become unavoidable, though experts caution that not every weight increase should be attributed directly to thyroid disease. The piece notes that the thyroid gland regulates energy use, metabolic rate, heart health, digestion and body temperature, so dysfunction can have wide-ranging effects. It does not cite specific figures, companies or executives, and offers no price or market data. The takeaway for readers is that thyroid disorders may explain some weight changes, but other causes should be ruled out before blaming the gland.
