Hi,
Thanks for posting your query.
With the available described details, there appears to be possibility of dyspepsia with decreased gastrointestinal motility.
Dyspepsia is a collection of symptoms consisting of acidic belching, abdominal heaviness and bloating, gargling sound , excessive
flatulence.
You should go for
complete blood count, serum amylase, liver function test, renal function test,
ultrasound imaging and endoscopy for better clarification.
You should also go for chest x ray.
You should also go for urea breathe test for H. Pylori.
Treatment depends on exact diagnosis.
Meanwhile, you should take
proton pump inhibitors along with prokientics and antispasmodics.
Take care,
Dr. Mayank Bhargava
