Hormonal imbalance occurs when there is too much or too little of a hormone in the bloodstream. Hormones are chemical messengers that regulate various bodily functions, including metabolism, growth, and mood. Common causes of hormonal imbalance include stress, poor diet, lack of exercise, and certain medical conditions like polycystic ovary syndrome or thyroid disorders. Symptoms of hormonal imbalance can vary widely and may include fatigue, weight gain, mood swings, and irregular menstrual cycles. Treatment options often involve lifestyle changes, such as improved diet and exercise, or medical interventions like hormone therapy. Addressing hormonal imbalances can help restore overall health and well-being.
