Every girl does not have Premenstrual Syndrome (PMS). The symptoms of PMS usually begin during the week before their period that lessen or disappear within 1-2 days after their period starts. Symptoms can usually be treated with lifestyle changes such as exercise and relaxation therapy. If these aren’t effective, prescription medicines are sometimes prescribed.
The most common symptoms include: mood swings, breast soreness, bloating, acne, cravings for certain foods, increased hunger and thirst, and fatigue. Other symptoms may include constipation or diarrhoea, irritability, and feeling blue or down in the dumps.
The diagnosis of PMS requires daily charting of symptoms over two menstrual cycles.
