I have now been sick for 5 months, I have severe nausea, vomiting and diarrhea. My stomache hurts all day everyday and is now affecting my sleep. My stomache has swollen and I have gained 3 pounds in a week. I can not keep any food and when i do it quickly makes an exit. I have been dehydrated constantly and I have no strength or stamina.This stomache condition also caused me to lose 40 pounds in 8 weeks. The doctors can't find anything but I know there is something wrong.
