Causes
Hormones often cause this problem. They start changes in the body that result in a period. They may be lowered by:
- Poor habits, such as lack of nutrition, too much physical activity, too much weight loss, or a lot of stress
- Health problems, such as polycystic ovary syndrome
- Delayed puberty
- Birth defects
Risk Factors
This problem is more common in high-level athletes, such as long-distance runners. Faulty genes may also raise the risk in some women.
Symptoms
Primary amenorrhea is when the first period has not happened in a young woman aged 15 years or older. Secondary is when a woman with regular periods has not had a period in 3 months in a row or a woman with irregular periods has not had a period in 6 months in a row.
Diagnosis
You will be asked about your symptoms and health history. You will also be asked about your history of periods. A physical exam will be done. This is enough to make the diagnosis.
More testing will need to be done to find the cause of the amenorrhea.
Treatment
Treatment depends on the cause. It may be treated by things like:
- Eating a healthy diet
- Exercising less often
- Managing health problems
- Lowering stress
- Correcting birth defects with surgery
Prevention
Female athletes can lower the risk by staying at a healthy weight by eating foods that support their level of training.
