My TSH levels are 5.68 and have been experiencing weight loss and excessive hairfall. Should I start treatment or wait and repeat tests?
Can an underactive thyroid cause weight loss and hairfall?
Yes, it can. When the thyroid gland is underactive, it can cause a slowing of the metabolism, leading to weight gain in some cases, but weight loss in others. Hair loss can also be a symptom of an underactive thyroid, as the thyroid hormone is responsible for hair growth and maintenance.
