Having had intestinal surgery I can no longer digest anything, it all releases, what can I take to strentghen?

I am also diabetic, so no alternatives in sweets if possible also it's been 2 years since the surgery and right after a meal I release. Liquid never hard or solid formed, every meal and every day. I have the BMs so often I get dehydrated and feel fatigued-dizzy and blah. Here is some details on the matter it was intestinal recession obstructure and twist which called for a removal of six feet small intestine to be removed. It was exploratory, so in a plea of someone somewhere about to help me out, what can I do to repair this reaction, perhaps due to the surgery or botched exploration, what is recommended to have a normal life again?
