Hormone deficiencies occur when the body does not produce enough of a certain hormone. Some common hormone deficiencies include: Thyroid hormone deficiency The thyroid gland regulates metabolism by producing thyroid hormones. A deficiency in these hormones leads to a condition called hypothyroidism. Symptoms can include fatigue, weight gain, feeling cold, constipation, dry skin, and depression. Hypothyroidism is generally treated with synthetic thyroid hormone medication. Growth hormone deficiency Growth hormone is important for growth and development in children. A deficiency can lead to slowed growth. Growth hormone deficiency in adults can cause decreased muscle mass, increased body fat, tiredness, and impacts on cholesterol levels. Treatment involves growth hormone injections. Testosterone deficiency Testosterone is an important sex hormone in both men and women. Low testosterone in men is called hypogonadism and can cause erectile dysfunction, low sex drive, decreased muscle mass, and fatigue. Testosterone replacement therapy can help alleviate symptoms. Estrogen deficiency Estrogen is an important female sex hormone. Declining estrogen levels are a hallmark of menopause, causing symptoms like hot flashes, vaginal dryness, and mood changes. Estrogen deficiency also leads to accelerated bone loss. Hormone therapy with estrogen can help manage menopausal symptoms. Hormone deficiencies can negatively impact quality of life. Blood tests help diagnose deficiencies, and hormone replacement therapies can alleviate symptoms.
