Hi.
Thanks for your query.
Noted the history and understood your concerns.
Abdominal distention can be due to many a factors as follows:
Intestinal flora disturbance due to antibiotics or some medications that you have not mentioned.
Brilinta and
Cholesterol medication such as any Statins can also cause gaseous distension.
Intestinal obstruction.
Increased gas producing bacteria.
Stress and anxiety can cause
aerophagia and thus gas bloating. This is common after major procedures like heart surgery, stent putting in and so on.
I would advise you the following in such a situation:
X-ray of abdomen in standing position.
Ultrasonography of abdomen.
Tests of blood and stool.
Clinical evaluation by your Doctor and referral for a Specialist if required along with correlation with the reports can help you get a proper diagnosis and thus appropriate management.
Till then take Activated charcoal, reduce stress and anxiety, avoid foods and beverages that cause gases and bloating.
