Loss of Period

I don't think that I am under weight, but for some reason my period has stopped. What could be the problem?

Well, you should know if you are underweight. What is your height and weight?

But you've nailed it -- being underweight is the most likely reason for your period stopping.

The second most likely is, even if you are at a healthy weight, you create enough bouts of starvation then the body plays it safe and stops your period because it figures there is unpredictable energy out there and you would die if you got pregnant due to lack of food/energy.

After that, the list is long and requires a doctor's visit. However, given your history, it's likely to be one or the other of the first two reasons I listed.

Cessation of menstruation can be caused by several things, most commonly being underweight.   Someone with a BMI below 19 is statistically much more likely not to get periods, for example.

Other reasons are connected.   A poor diet with a lack of nutrition (too low in fat will do it), insufficient calories, over-exercising, too-low body-fat %.  And then there are illnesses which have nothing to do with size, diet and activity... quite a few of those.

So if you're underweight, gain weight.  If your diet is poor, improve it.  If you do too much exercise, reduce it.  And if you fail to get a period for three months consecutively then see your doctor

Along with the other reasons the above posters have given, over-exercise is another common culprit.

I lost my period and I was not underweight. I lost weight the healthy way and it still happened. I think sometimes your body just needs to re-adjust. I lost it for about 9-10 months. I went to doctor's etc, and then I took matters into my own hands and just began eating more healthy fats. It worked! I think I also upped my calories a little bit. Sometimes restricting too much can be the problem too.

If you are underweight, admit it and gain some. Or cut back on exercising if you are doing too much. Good Luck :)
