Hi.
Thanks for your query.
Noted the history and understood your concerns.
An Engineer of 21 years, starting career recently and having chest burning after lunch and not having clear, free motion can be due to the following reasons.
GERD that is
gastroesophageal reflux disease.
Gastritis and acidity related problems.
No clear motion may be due to colitis or IBS that is
irritable bowel syndrome and may be related to GERD as anxiety and/or stress are the main causative factors.
I would advise you the following in such a situation:
Get started with a PPI like
Omeprazole.
You have to take antacid every three hours,
Domperidone at 8 hourly interval.
Antacid every three hours the first dose being taken the moment you get up in the morning.
Soft, bland, small frequent meals.
Early to bed and 8 hours sleep.
No smoking or alcohol.
If there is no complete relief, then go for an opinion of a Gastroenterologist and an upper GI endoscopy along with management of the stool problem after tests of stool.
