Although most women experience some PMS symptoms, up to 10 percent of menstruating women are actually incapacitated by its effects. "If a woman suffers from five or more PMS symptoms and experiences a significant monthly mood change that affects her work, relationships, or life in general, then she should absolutely seek help," says Beth Burch, ND, of Transitions for Health in Portland, Ore. In addition to considering the following symptoms, check in with friends and family to shed light on how drastically your hormones affect you each month.

Common PMS symptoms include: acne, anxiety, bloating, breast tenderness, clumsiness, cramps, crying spells, depression, dizziness, headaches, insomnia, intestinal disturbances, lower back pain, mood swings, sugar cravings and weight gain.
