Brief Answer:
Investigations to get a perfect diagnosis is most important.

Detailed Answer:
Hi Young Man.

Thanks for your query and relevant history, albeit small.
May I please know some other details, which will help me to get and give you a clearer idea about your problem of 2 months::
-Is this for the first time (these 2 months) that you are having the present problem or had similar problems in the past?
-Any other associated history of
Loss of appetite
Loss of weight
Evening rise of temperature
Feeling week by evening or so.
Nausea, vomiting.
Or any thing which you feel related or unrelated to the present problem.
-Any blood, urine , stool, ultrasonography CT scan of abdomen, X-ray of the chest done?

To recapitulate the history:
Male - 26 years - started as loose motions for continuous 1 week - complaints of bloating, belching, sounds (borborygmi), loose stools for more than 2 months - UGI Endo done - now even for white rise- visited a Doctor and got an antibiotic for E coli... Wants advise...

After reading carefully the whole recapitulations, I would advise you the following as your problem is more than 2 months::
-Blood : CBC, ESR, sugar, liver function tests, kidney function tests, most important Thyroid function tests, Quantiferone Gold test for TB.
-Urine : routine and microscopy
-Stool : routine, microscopy, occult blood.

-X-ray of the standing abdomen for intestinal shadows to see for subacute intestinal obstruction (you have borborygmi- sounds)
-Ultrasonography and CT scan of the abdomen
-If these investigations are suggestive Enteroclysis (Barium study under Fluoroscopy control for direct visualization of movement of barium through intestines and to detect any abnormal hastening, anatomical variations.
-Colonoscopy and biopsy is required.

All these investigations will definitely helps us to find an appropriate diagnosis.
** I would like to stress this point as the proper diagnosis alone can give you the most appropriate treatment and cure.

Since upper GI Endoscopy has already been done and shows the reports as secondary to the intestinal problems. (This will be nicely covered with medicines but not as important as the intestinal problems)..
You have already taken the antibiotic for E coli.

I would also advise you the following:
Medicines ::
You need to have a prescription of a Doctor, please discuss this with a Gastroenterologist to get a prescription. I would like to know which medicines have you taken in the past and in which dosage
Vit A and Vit D in therapeutic doses,
Multiviatamins ,
probiotics,
anxiolytics help a lot.
Stress and anxiety can add to the existing problem a lot ( Either as a causative / contributory factor or as an effect of a long standing problem).

I hope this answer helps you to get a proper diagnosis, and get a proper further treatment. Please feel free to ask for more or if you need further clarifications if you feel there is a gap of communication.

Brief Answer:
Lax XXXXXXX / Hiatus Hernia does not cause this.

Detailed Answer:
Hi XXXXXXX
Thanks for your feedback about the tests, about my questions, the way the symptoms start, weight loss as you are eating only white rice that too in less quantity, worry about the Lax XXXXXXX and hiatus hernia, tired, weak, and consultations with 2 Gastroenterologists in XXXXXXX who advised Yoga, and your query.

I can understand the plight you are going through.

Your Query :::
(my query is Whether due to LAX LES/Hiatus hernia which is causing air to enter stomach and because of that am getting this problem. I could feel that like air entering.)

The air can not enter due to lax XXXXXXX and / or hiatus Hernia.
The air entry is restricted by the Upper esophageal sphincter (UES) , which is not diseased. So the problem is not due to XXXXXXX (Lower esophageal sphincter).
You can have aerophagia due to stress but this can not cause so much of a problem as you are having. So you can omit this thought out.

Yet, I would like you to do the following tests IF NOT YET DONE:
Thyroid function tests
Enteroclysis
CT scan of the abdomen.
These may give you / us a clue.

As for the food:
You should take every sort of a food and then see which one is causing the problem.
Start the normal diet as you had before 3 months; taking white rice alone is not anyway helping.
If you stay at home with family, you have to start all the foods, have to observe and practically write what you had / have taken and see the effect, believe me - there would be only a few things you would notice to have increased your problem. So why to restrict unless you are sure about the foods and beverages, start all the seasonal fruits if suit you.

I would advise you the following::
Please get the few tests which I recommended, if not already done.
If all the tests I mentioned are normal, then only you can be taken as a case of IBS.
The most important reason of IBS is Stress and anxiety.
''STRESS'' = stress is the most important cause of IBS. Please remember and you must have observed that when you do not have stress your problem with IBS is reduced
Change of lifestyle.
I think 'may be' you are not coping with something.

Remember the simple dictum in IBS : you have to undergo necessary investigations before you are labelled as a patient of IBS. Secondly IBS is easily treatable, controllable and within the ambit of your psychological set-up.
The moment the instigating or precipitating factors come into play the problem may re-start.

Take one more opinion of a Old / XXXXXXX General Surgeon or a Surgical Gastroenterologist. This may help you more.

I hope I have been trying my best to help solve your problem and will be happy to assist you till we have the final diagnosis and perfect treatment till you are cured of the problem. ( May I just know whether you are married or not and the job or the work you are into)

Brief Answer:
Heart is just above the stomach, normally felt in some.

Detailed Answer:
Hi.
Thanks for your appreciation.
Get the feedback about your single status and Software Engineer as a profession.

Your Query:
The lower part of the heart is placed just above the stomach, separated by just a thin diaphragm. When you are eating or drinking fast or doing walking, it is natural in many to have feeling of the heart beat in stomach. I do not think this is to worry about unless you have some cardiac problem.

Good that the stool culture is negative.
