Hello
I share your concern.
Looking at your description and previous history of
peptic ulcer 2 years back, I would advise you for battery of investigation like blood for CBC, liver function test and ultrasound abdomen for liver,
gall bladder and pancreas or an upper gastrointestinal endoscopy if need be.
Meanwhile I would advise you to take antiacidity medicine like ranitidine or
pantoprazole group of drugs with antacids for 4-5days and follow these guidelines.
1. Avoid fatty fried spicy and junk food and carbonated beverages.
2. Have lots of fresh fruits and vegetables with
dietary fiber supplement in your diet.
3. Try to avoid stress and anxiety by relaxation exercises, yoga and meditation.
4. don't skip meal and avoid overeating.
5. you should not drink or smoke.
Straight answer to your question is as follows.
Flutter and resurgence of symptoms might be related to stress and anxiety, faulty food habits, drinking or smoking,
H pylori infection and many other causes.
So you should try to identify any underlying cause for this issue and accordingly it's prevention.
Hope this answers your question please feel free to ask for follow up question I will gladly answer you.
Best wishes
