Menstruation is a natural and regular part of the reproductive cycle. It occurs when the lining of the uterus sheds through the vaginal canal, typically lasting for 3 to 7 days. This monthly process is triggered by hormonal changes in the body and usually begins during adolescence, continuing until menopause.
During menstruation, women may experience a variety of physical and emotional symptoms. Common physical symptoms include abdominal cramps, bloating, breast tenderness, and fatigue. Hormonal fluctuations can also lead to mood swings, irritability, and changes in appetite.
