Hi, my cousin is suffering from unknown health problem that's related to digestive system. After every meal she got heavy headache, tiredness, diaherea and unconsciousness some times. Recently we suspect that was severe ulcer. But the medicines for ulcer didn't work and leads to worsen, from young age she had frequent headache and allergy to smells and foods. Few years ago we tested for allergy and got negative results and immunity test also shows normal. After few years while the problem get worsen. We suspect that ulcer and physician suggested some drugs for ulcer (ppi and antacid) but ppi s makes her loss conscious and very weak soon after taking those tablets. This symptoms also happens when eat normal foods. We took her to many specialists and each of them suspected different diseases. They are 1.food allergy 2.immunity disorder 3.vitd deficiency 4.ulcer symptoms: headache and tiredness after meals, sometimes diarrhea and unconsciousness after meals, sometimes blood found in stool, vomiting after meals, allergy for smells.
