Hi! I m sixteen years old, around 5 8 , and I weigh around 120lbs. Recently, I ve been feeling unusual after meals. I ll eat pretty large portions (which is strange in itself for me) and then feel hungry again about an hour later despite eating until I m full. Also, after I eat something, my stomach starts cramping up pretty bad and I ve had mild diarrhea twice this month which is very unusual as well. This has never happened to me before. I have no known medical problems and I haven t been sick lately. I am about to start my period in about a week and a half so maybe that s part of it? This has just never been something that s happened before, during, or after my period so I m just wondering if maybe it s something else.
