Premenstrual Syndrome (PMS) refers to a group of physical and emotional symptoms that many women experience in the days leading up to their menstrual period. These symptoms can vary from woman to woman, but some common ones include mood swings, irritability, bloating, breast tenderness, fatigue, headaches, and food cravings. The exact cause of PMS is not fully understood, but it is believed that hormonal fluctuations during the menstrual cycle may play a role in triggering these symptoms. Treatment options for PMS can include lifestyle changes such as exercise, stress management, and dietary modifications, as well as medication to help alleviate specific symptoms.
