Thyroid problems in men relate to hypothyroidism, which refers to an underactive thyroid gland and low metabolism, or hyperthyroidism, which refers to an overactive thyroid gland and an increased metabolism, notes BodyLogicMD. Each condition has different symptoms and requires different treatment options.
An underactive thyroid gland is much more common than an overactive thyroid gland, reports BodyLogicMD. Some of the associated symptoms in men include hair loss, fatigue, dry skin, weight gain, constipation and cold intolerance. Not all tests are able to detect hypothyroidism in men.
Hyperthyroidism has different symptoms than hypothyroidism and include muscle weakness, breathlessness, anxiety, trembling hands, insomnia and weight loss. Initially, the symptoms are difficult to detect but gradually grow more severe. An increase in metabolism results in significant weight loss and an increase in appetite, mentions BodyLogicMD .
The thyroid gland represents the biggest gland in the neck area, states EndocrineWeb. It takes the shape of a butterfly and has a sole function of producing thyroid hormone. This hormone regulates the body's metabolism. Issues with the thyroid gland relate to its ability to produce hormones or an abnormal physical state, such as swelling. Levels of T4 and T3 determine the overall health of the thyroid gland. The technique to measure thyroid hormones is known as radioimmunoassay.
