Alright my friend, NOT ME, she wasnt eating much and so i made her start eating again so now shes eating regular. But i just recently found out that her period (menstral cycle) is late about 15-20 days. So my question is when she was eating so low with dramatic weight loss had to do with her missing period. Oh and by the way she still hasnt started her period but she said she is feeling the cramps.

Excessively low body fat can have an impact on menstruation, more commonly in gymnasts and the like. However, she needs to take a pregnancy test to rule that out first and foremost. If it is negative and still no period, get her to a doctor to find out what is going on. There can be a variety of factors that influence menstruation.

Women are very complicated beings, as my father once said

"Son... If it has tits or wheels you will never undrestand it"

she should take tests for sure, but diet has a massive effect on ur whole body. Everything chages due to the new stress and conditions going on inside you. Its no surprise that her periods will be effected.

that is a hillarious quote! made me laugh, and im a woman..LOL

That was pretty damn funny! Not too far from the truth for a lot of men.

I don't think she's pregnant, she's not that type of women plus shes very young. But she said shes going to the doctor this tuesday to check out whats going on. I really think its b/c of sudden change of life style. And i have heard people have missed their period for a month before and its no big deal.
