Premenstrual syndrome, PMS is often perceived as a trait of hysterical, hypochondriac women. In fact, it is a serious medical condition with a number of unpleasant symptoms:

• fatigue and trouble sleeping
• upset stomach, bloating, constipation or diarrhea
• headache
• appetite changes or food cravings
• joint or muscle pain
• tension, irritability, mood swings, or crying spells
• anxiety or depression
• trouble concentrating or remembering
• breast swelling and tenderness

As simple a measure as higher intakes of calcium and vitamin D might be helpful in case of PMS. (Archives of Internal Medicine, June 2005).
