Prevention

Here are some steps you can take to help prevent missed or irregular periods.

• Avoid fad diets that greatly restrict calories and food variety, and avoid rapid weight loss. To maintain a healthy weight, focus on eating a variety of low-fat foods. For more information, see the topics Healthy Eating and Weight Management.
• Use contraception consistently, as directed by your doctor. For more information, see the topic Birth Control.
• Increase exercise gradually. For more information, see the topic Fitness.
