Can obesity delay a girl's first period?

ANSWER

If you’re obese, you may not have your first period at the usual time, either. To set a monthly menstrual cycle, your body needs a normal range of fat levels. Too much or too little body fat can lead to delayed periods. Obesity for someone 5 feet, 2 inches tall starts at 155 pounds.
