1. Changes in Body Weight
Since the body’s metabolic rate is closely associated with the action of the thyroid, an unexplained change in body weight may signify thyroid trouble. Weight gain with no change in appetite, exercise regime, and stress levels is symptomatic of low thyroid hormone production. On the other hand, weight loss for no apparent reason may be provoked by excess thyroid production. The former condition—hypothyroidism—is far more commonly observed, especially in women. Either way, if there is an unexpected change in an individual’s body weight, he or she should get their thyroid hormone levels checked.
