Male Thyroid Symptoms

Updated February 21, 2017

The thyroid is a gland in the neck that controls the hormones that regulate metabolism and other integral body functions. When the thyroid is malfunctioning (it can be either overactive or underactive), men will notice the following symptoms and should see their doctor or endocrinologist.

Weight Gain/Loss

Men suffering from an underactive thyroid (hypothyroid) will gain weight or be unable to lose weight despite exercise and a reduced-calorie diet. Men suffering from an overactive thyroid (hyperthyroid) will find it difficult to put on weight, despite supplements and additional meals or muscle-gaining workouts.

Body Temperature

An underactive thyroid in men will cause a cold feeling, despite layers of clothing or mild temperatures. An overactive thyroid will make males feel sweaty, hot and uncomfortable even with air conditioning or cool weather.

Sexual Dysfunction

Men suffering from hypothyroid disease may find it difficult to achieve orgasm or prolonged sexual activity. There may be a lack of interest in sex.


Men who suffer from both thyroid dysfunctions may experience depression, mood swings, sadness, irritability and a feeling of hopelessness. Often, thyroid disorders are misdiagnosed as depression until the patient undergoes blood testing to show the body's imbalance.

Sleep Changes

An underactive thyroid may increase the man's desire to sleep far more than he is used to. Feeling tired all the time (despite rest, vitamins and a good diet) is a main symptom of hypothyroid disorder. Conversely, a male suffering from an overactive thyroid may find it impossible to get rest. Men who are hyperthyroid find it difficult to sleep (whether it is to fall asleep or stay asleep for long periods) and are constantly waking up with racing hearts and pulse.

Well-Known Sufferers

Thyroid disease is easily regulated with daily medication. The following men have led successful lives in the public eye while suffering from thyroid disease: Rod Stewart, Roger Ebert, Peter Gotti, George Bush Sr., Ben Crenshaw, Bobby Engram and Carl Lewis.
