I exercise about 2 hours a day every day. In the last 3 months I've lost 26 pounds, but my period is gone. What should I do?

Many things can make a girl stop getting her period — including exercising a lot and losing weight quickly, especially if she doesn't consume enough calories and healthy foods.

Two hours of exercise a day can add up to a lot of calories burned. You should take in more calories now than when you weren't as active.

Make an appointment with your health care provider. They can make sure nothing else is stopping your period, and work with you on a healthy eating and exercise plan. Your provider may ask you to increase your calories and decrease your workouts to get your body and your cycle back on track.
