Dear Surajitpal, Good morning! How are you? Thanks for posting your query. I appreciate your concern for the dysentery, weight loss, etc After having gone through your problem I am of the opinion that the features described are suggestive of some chronic inflammatory condition of the intestines referred to as inflammatory bowel disease (for example ulcerative colitis). In view of significant weight loss (8 Kgs since last 7 years) with bloody diarrhea you are advised to consult a physician or a gastroenterologist for proper clinical examination and may be you will have to undergo certain investigations like CBC, Stool analysis, ESR, Colonoscopy, etc to diagnose the condition. Other causes for the above condition include irritable bowel syndrome, polyps, and cancer involving the colon. Hope these suggestions could be useful to you in getting the consultation, a proper workup and of course the treatment. Wishing you best of your health. Take care.
