The endocrine system is a complex network of glands and organs that produce and release hormones into the bloodstream to regulate various bodily functions and maintain homeostasis. Key glands in the endocrine system include the pituitary gland, thyroid gland, adrenal glands, pancreas, and reproductive organs (ovaries and testes). Hormones act as chemical messengers, traveling through the bloodstream to target cells and organs, where they exert their effects on metabolism, growth and development, mood, sleep, and reproduction.

Maintaining a healthy endocrine system is essential for overall well-being and hormone balance. A balanced diet rich in nutrients like vitamins D, B, and C supports glandular function. Regular physical activity and stress management techniques such as meditation and yoga help regulate hormone levels and reduce the risk of endocrine disorders.

Common endocrine disorders include diabetes mellitus, thyroid disorders (hypothyroidism and hyperthyroidism), adrenal insufficiency, and reproductive hormone imbalances. Symptoms such as fatigue, weight changes, mood swings, and irregularities in menstrual cycles or libido should prompt evaluation by a healthcare professional.
