<s>[INST] Hi, I have periodic stmach bloating - swells up to like 9 months pregnat - and hard. I am 60 years old. Have had a CT scan, MIR scan and blood test -nothing showed up. It can be very painful. This has been going on for about 5 weeks. No logic as to what I eat - but do have an allergy to eggs [/INST] Hi, abdominal bloating is fullness,tightness, distension if abdomen u can do,1 ) don't eat too much carbohydrates type diet2) don't take cold drinks specially from straw3) don't take too much dietary fibers as it delayes your stomach emptying time4) loose weight if obese5) don't take rest for atlest 2 hrs following meal,slow walking would be helpful but not fast6) PPI s can help but only after doctor's advise </s>
