Question

which is a common symptom that results from an overactive thyroid gland?
hair growth
weight loss
low insulin levels
onset of diabetes

Explanation:

An overactive thyroid gland (hyperthyroidism) speeds up the body's metabolism. This increased metabolic rate often leads to weight loss as the body burns more calories. Hair growth is not a typical symptom. Low insulin levels and the onset of diabetes are not directly related to an overactive thyroid.

Answer:

weight loss
