Endocrine dysfunction refers to abnormalities in the hormonal system of the body, which controls various functions such as metabolism, growth and development, reproduction, and stress response. Endocrine disorders can result from dysregulation of hormone production, secretion, or action, leading to symptoms ranging from fatigue and weight gain to infertility and growth abnormalities. Common endocrine disorders include diabetes, thyroid disorders, adrenal insufficiency, and pituitary gland disorders. Treatment for endocrine dysfunction often involves hormone replacement therapy, lifestyle changes, and in some cases, surgery.
