Poor gut health

Two bouts of Covid infection impacted my gastrointestinal health.im unable to control my bowels n get diarrhoea after an hour of eating.Im on the lookout for the nearest gas station toilets or shopping malls loo as im driving on the highway.woe is me if im caught in a long traffic jam or flash flood. ive not travelled to a foreign country by plane since ive gutted my bowels and unless i wear adult diapers its so uncomfortable to travel on the lookout for loos. ive restarted drinking kefir,kombucha n probiotic food like kimchi.ive given up travel dreams unless its domestic n i know where to find clean loos.hope year of the snake will restore gut health or indigestion or diarrhoea upsets my mood for travel
