A period, or menstruation, marks the beginning of the process by which the uterus, or womb, prepares itself for pregnancy.  Sarah has a look at the process and what can go wrong including missed or late periods, intermenstrual bleeding, heavy periods, painful periods, pre-menstrual syndrome (PMS), and the menopause.

It looks like hormones are responsible for changes in the menstrual cycle (obviously) I bet that irregular and heavy periods are most likely do to irregular levels of hormones in the body, probably stemming from diet.

Who knows what kind of crap they put in food nowadays it could be effecting people.

Do you have any evidence for that, or are you just slandering the food industry and its overseers?

I was always wondering why it is that anorexic girls loose they periods. It is said that it is body's defence against starvation, but I would consider it to be pretty important process in the body, so I don't know why it would stop in such a case.

Could be a safety-mechanism to prevent pregnancy :  if they're already starving then there won't be enough food to "eat for two".

Gonadotropin Releasing hormone (GnRh)  made by the hypothalamus, travels through a tiny blood vessel to the pituitary which releases FSH or Follicle Stimulating hormone, that gets the menstrual cycle rolling, as well as Lutenizing Hormone, that triggers ovulation. So you have structures in the brain that are connected to the nervous system, as well as the endocrine system, and may be sensitive to feedback from both, or disruptions in either system.

According to wiki, feed back from estrogen and androgen levels in the rest of the body, polycystic ovarian disease, insulin, levels of neurotransmitters (norepinephrine, GABA, glutamate, dopamine) and of course pregnancy, can affect GnRh release.

It makes sense that evolution would discourage pregnancy in an undernourished female who may not have sufficient reserves. Generally if it's a contest nutrition-wise between the fetus and the mother, the fetus wins, but that endangers her level of care afterwards and future productivity.   Also, menstruation seems to be somewhat triggered by girls reaching a certain weight and body fat ratio, so if they dip down below pre-puberty levels, that may have something to do with it as well.
