Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Fluttering sensatioay be due to anxiety which may cause wall muscle contraction lead to that feeling. Other possibilities like abdominal wall muscle twitching or excessive caffeine or alcohol intake or hypokalemia or hypocalcemia or after vigorous exercise etc. Until examination is done it is difficult to say what it is. Avoid spicy food and alcohol avoid smoking and caffeine drinks. Use tablet Pantoprazole before breakfast for one week.Do yoga and meditation regularly. If symptoms not improved please consult your doctor he will examine and treat you accordingly. Hope I have answered your query. Let me know if I can assist you further.
