<bot>: Hi. Thanks for your query and proper history. Since your girlfriend has severe pain in abdomen along with diarrhea, and she also has started her periods, the causes of the pain can be :-Gastroenteritis if the pain is all over the abdomen and has associated symptoms of nausea, vomiting, bloating, fever etc. -These can be menstrual pains if she has these the same way in previous periods. If these are due to gastroenteritis, it is better that you take her to Er, get her examined and treated properly.
