Hi. Thanks for your query. Noted the history and understood your concerns. 3 years is a long time to suffer from digestive issues like malabsorption syndrome, IBS, Feverishness, weakness, failure of antibiotics to cure, helped by Providac caps and there is fissure-in-ano too. All these things indicate that you need a proper clinical evaluation, examination and investigations to get the proper diagnosis whichi is very important for proper management. Hence I would advise you the following: Send the stool sample for three consecutive days for lab tests. Test of blood particularly for Thyroid and Liver functions. Ultrasonography followed by a CT scan of the abdomen helps. Colonoscopy and biopsy too helps. All these things will help to get a proper diagnosis and gives a plan for proper management. If all the investigations are normal, then you can ask for treatment for IBS that is irritable bowel syndrome and avoidance or treatment of the stress and/or anxiety can change your life.
