An overactive thyroid, known as hyperthyroidism, speeds up the metabolic process in the body. Overactive thyroid symptoms in men have a few similarities to those of women, with some differences.
Thyroid problems are more common in women, usually because of menopause or after childbirth, Dr. Jerome M. Hershman
wrote in an article for Merck Manual. The thyroid gland helps regulate cells throughout the body. An overactive thyroid produces too much of the thyroid hormone and may interfere with body functions.

Hyperthyroidism often causes the thyroid gland to enlarge, leading to a goiter or thyroid nodules. In some cases, the gland may become painful or tender.
Overactive thyroid symptoms in men might not be so noticeable in the beginning, but they become more severe over time,
according to BodyLogicMD, a network of doctors specializing in hormone replacement therapy.
Weight loss and weight gain are symptoms men with hyperthyroidism have in common with women suffering from the disorder. The speeding up of metabolism brings about weight loss, BodyLogicMD notes. However, men develop an increased appetite because of increased energy needs from the overactive thyroid, so weight gain may occur with age.

Other symptoms in men with an overactive thyroid include muscle weakness, insomnia, anxiety, breathlessness, trembling hands, fatigue, heat intolerance, increased bowel movements, and hair loss, according to BodyLogicMD. Osteoporosis, which causes brittle bones because of hormonal changes, may occur in severe cases.
Breast development is also a
symptom of an overactive thyroid in men, according to MedlinePlus, a National Institutes of Health website. Symptoms may vary among people with hyperthyroidism, including clammy skin, high blood pressure, itching, nausea and vomiting, irregular heartbeat, and difficulty concentrating, MedlinePlus points out.
Although women are more at risk for hyperthyroidism, these thyroid symptoms in men indicate a visit to the doctor may be necessary. Medications can help stop the overproduction of thyroid hormones. If surgery is necessary to remove the gland, thyroid hormone replacement medication is prescribed.
