Hi. Thanks for your query. Noted the history and understood your concerns. Since there is no hernia, there is ano need of any surgery and is not related to the present problem of rumbling stomach, gases and fresh blood in the stool. This indicates that there may be colitis, enteritis with inflammation in the rectum or distal colon causing blood in stool or simply due to development of fissure or piles that is hemorrhoids that bleed. I would advise you the following: Consult your Doctor for clinical evaluation,m examination and investigations of the stool and blood to get a proper probable diagnosis so that a proper management can be done. A course of an antibiotic active against intestinal infection, metronidazole and probiotics should help to get a relief. This will alleviate the symptom that you have and help early and proper recovery. Use boiled and cooled water. Take soft and bland diet, banana, curds and rice. Activated charcoal tablets and multivitamins are also needed as also a PPI like OMeprazole.
