Two things you can do to help reduce irregular periods are to maintain a healthy weight and exercise regularly. This will help keep your body’s hormones balanced and regulated. • Maintain a healthy weight — Changes in weight can affect your periods. If you are overweight or obese, losing weight can help to regulate your periods. On the other hand, extreme weight loss or being underweight can cause irregular menstruation. That is why it is important to maintain a healthy weight. Women who are overweight are also more likely to have irregular periods, and experience heavier bleeding and pain than women who are at a healthy weight. This is due to the impact that fat cells have on hormones and insulin. If you suspect your weight may be affecting your menstrual periods, get in touch with your doctor right away. They can help you identify a healthy target weight, and come up with a weight loss or gain strategy. Being underweight or overweight can cause irregular periods. Work with your doctor to help you find a plan to maintain a healthy weight. • Exercise regularly — Exercise has a whole host of health benefits that can help regulate your periods. It can help you reach or maintain a healthy weight and is commonly recommended as part of a treatment plan for polycystic ovary syndrome (PCOS). PCOS can cause menstrual irregularity. Results show that exercise can effectively treat primary dysmenorrhea. Seventy college students with primary dysmenorrhea participated in the trial. The intervention group performed 30 minutes of aerobic exercise, 3 times a week, for 8 weeks. At the end of the trial, the women who performed the exercises reported less pain associated with their menstrual periods. More research is needed to understand how exercise affects menstruation, and what direct effects, if any, it can have on regulating your period.
