Hello, Abu, Your mother has had diarrhea for some time. I hope the doctors have done all the tests necessary to find out what is the reason. I hope they have tested the stool for Ova and parasites, do colonoscopy and biopsy to see if she has colitis, ruled out Crohn s disease, Celiac disease, lactose intolerance etc. Also check for other organisms such as Giardia, Cryptosporidia, viruses like Norwalk agents etc. If she was on antibiotics, we have to rule out C.Difficile infection. As for Econorm, it is a probiotic and puts good bacteria into the intestine which is good. So, she can take it regularly. For electrolyte replacement she can take electrolyte solutions that you can get at the drug store. If you can get it, coconut water is very good. I wish her well.
