Why is there pain in the stomach when menstruating? What are cramps?
Many women can have painful cramps during the menstruation. You may notice pain in the lower belly and/or lower back area 1-2 days before your period starts, which may last for around 2-4 days. Menstrual cramps are caused by uterine contractions (when the muscles in the uterus tighten and relax allowing blood to leave the uterus), and it's normal. The lining of the uterus releases special chemicals called “prostaglandins.” These substances can increase the strength of the contractions, especially if the levels rise. High levels of prostaglandins may also cause nausea and lightheadedness. if pain is not relieved with over-the-counter medications, and especially if it causes you to miss daily activities, you should check in with your healthcare provider (HCP).
