<s>[INST] Hi, I m male, 31 years of age, and in good health, exercising 5-6 times per week, with a good diet . I ve started having this bubbling/ flutter sensation in the lower left abdomen . Last night I woke up completely drenched in sweat and thats when I noticed this bubbling/flutter sensation happening in my lower left abdomen, however not painful at all, just an unusual feeling. I got back to sleep then got up at 5.30 am to go to the gym for 3 km swim. I ve just had breakfast (coffee, muesli with fruit and yoghurt) and have noticed the bubbling/flutter sensation happening again (comes and goes). It actually reminded me that this happened last night which I had since forgotten about. Can you let me know what this could possibly mean? Thanks, [/INST] Dear Damien It's probably nothing. Why do you worry if you don't have any pain? If you didn't notice stool color or frequency changes then there is really no reason to panic. You could have some kind of food poisoning. Did you fell bloated? There is a possibility that you suffer from IBS. So have this on mind. If you have an obstipation, chronic diarrhea, blood in the stool or intensive bloating then you should visit your gastroenterologist. More serious disorders such as tumors, Crohn's disease etc. would present with much worse symptoms. Wish you good health,  </s>
