Loose stools and watery most of the time

Hi, It's almost a month I had loose motions one weekend and it got cured in a day or two, problem is from that day i am facing issue of loose watery stools 5-6 times sometimes more, I eat something and go to loo. Gas and bloating in case dont go to loo then watery stool comes and I get fine. I had ayurvedic medicines it cured me for a couple of days but then it again started, week back started allopathy tab sibofix 400 mg taken along with cap velgat as probiotic, I got some tests done and sgot is 40.6 which was normal few months back, I don't drink, yes few months had food from outside. Should I go through ultrasound or some other tests to know the cause, is it some kind of food allergy or what can be, I feel tired and drained all the time and low energy.
