The odds of having secondary amenorrhea increase if you're severely underweight (less than 15 to 17 percent body fat) or obese. The Centers for Disease Control and Prevention considers someone obese if that person has a body mass index (BMI), which is calculated from your height and weight, of more than 30. For example, a 5-foot-9-inch (1.75-meter) person weighing more than 203 pounds (92 kilograms) would be considered obese.
