Hi! you have mentioned about bleeding with motion but not about any other associated symptoms like abdominal pain, change in defecation habit, nature of stool liquid or semisolid, nature of bleeding fresh or mixed with stool. Blood in stool without pain during defecation can be due to many causes like hemorrhoid, diverticolosis, duodenal ulcer , gastric ulcer, ulcerative colitis, portal hypertension etc. To rule out others and to reach the exact diagnosis you should go for following investigation if possible USG whole abdomen, X ray abdomen, upper G.I. endoscopy, rectosigmoidoscopy , CT scan of abdomen and urea breath test for H.Pylori infection. According to your present complain of abdominal discomfort and bloating associated with meal together ,associated anxiety and panic attack during night points toward stress ulcer(peptic ulcer). Untill not daignosed for the relief of symptoms you can take pantoprazole 40 mg half an hour before meal once a day or antacid two tab or two tea spoon, avoid NSAIDs, avoid fried foods, chillies, pickles, alcohol, strong coffee and tea and smoking, take rest.For the management of anxiety and panic attack you can go with diazepam 5 mg at bed time. Bleeding for such a long time may result in development of anemia, so get your complete hemogram and consult a physician for its proper management or if found anemic then take ferrous sulphate tab. Consult a specialist with report of all investigation for proper management.
