The thyroid gland is in your neck, just below the Adam’s apple. The gland is responsible for producing hormones that affect your metabolism. When the gland is not producing enough hormones, the condition is called hypothyroidism. The symptoms of this condition occur over a number of years. Doctors must take blood tests to give an official diagnosis of hypothyroidism when the symptoms are present.
Other conditions cause joint pain as well. When joint pain is present along with other hypothyroidism symptoms, blood tests determine whether the pain is the result of the condition. Joint pain may occur in any of the joints in the body.
An increase in weight that you cannot explain is a symptom of an underactive thyroid gland. The weight gain must not be caused by a medication or overeating. When there is no change in diet or medication and weight increases, it may be a sign that the metabolism is not functioning properly. The metabolism is the rate that the body burns calories.
