Thyroid malfunction in males, eitherhyperthyroidism and hypothyroidism, presents with many of the same symptoms as in women, including intolerance to heat and cold, vocal changes, irritability and increased nervousness, weight loss or gain, dry and coarse hair, vision problems, sleep disturbances and more. The conditions that men experience from thyroid issues depend on the underlying cause and type of thyroid problem; hypothyroidism, characterized by low thyroid hormone production, causes the body to use energy more slowly than usual and may trigger weight gain, while hyperthyroidism, oroverproduction of thyroid hormones, generates anxiety and speeds metabolism, potentially causing weight loss.
Thyroid diseases occur in people of all ages and affect men and women. However, according to the Cleveland Clinic, women have a five to eight times greater chance of developing thyroid issues than men. Thyroid diseases, however, present many identical symptoms in both genders, and stem from the same causes. In men and women, hypothyroidism might develop from thyroiditis, Hashimoto's thyroiditis, iodine deficiency and non-functional thyroid gland. Symptoms of underactive thyroid include dry, coarse hair, weight gain, forgetfulness, fatigue, cold intolerance and vocal changes. Hyperthyroidism stems from Graves' disease, nodules, thyroiditis and excess iodine intake. Symptoms include weight loss, nervousness and irritability, disrupted sleep, enlarged thyroid gland, sensitivity to heat and vision disturbances. To identify thyroid problems and rule out other conditions causing similar symptoms, doctors perform a simple thyroid stimulating hormone (TSH) test.
