Hormonal imbalances can cause a variety of health issues and can be the result of a number of different conditions. Some of the most common hormonal imbalances include hypothyroidism, hyperthyroidism, adrenal gland disorders, pituitary gland disorders, and polycystic ovary syndrome. Hypothyroidism is a condition where the thyroid gland does not produce enough hormones, resulting in fatigue, weight gain, depression, and dry skin. Hyperthyroidism is a condition where the thyroid gland produces too much of the hormone, resulting in rapid heart rate, weight loss, anxiety, and irritability. Adrenal gland disorders cause the adrenal glands to produce too much or too little of the hormones cortisol and aldosterone, which can cause fatigue, weight gain, low blood pressure, and high blood sugar levels. Pituitary gland disorders can cause an overproduction or underproduction of certain hormones, resulting in changes to sexual development, growth, and other body functions. Lastly, polycystic ovary syndrome is a common hormonal imbalance in women, resulting in irregular periods, excess hair growth, acne, and obesity.
