Detailed Answer:
Hello and thank you for choosing HealthcareMagic for your query,

I've gone through all your details and appreciate your concern.

Most likely, the problem you are having is called Dyspepsia.

Dyspepsia, in layman's language is known as indigestion. It is a term that describes discomfort or pain in the upper abdomen. However, it's not a disease in itself. Dyspepsia is a group of symptoms which often include bloating, belching nausea etc.

As the onset in your case is acute(one day history) Most likely cause of change in color of stool is due to intake of particular food.It takes about 72 hours for food ingested to clear up from body hence wait for minimum 72 hours for stools to return back to normal color:
Take a proton pump inhibitor like Esomeprazole 40 mg twice daily along with a prokinetic drug (eg.Domperidone) for 3 days. This will provide you symptomatic relief from symptomsof dyspepsia (you may need to obtain prescription for this from your local physician).

Antacid like Pepto bismol continue taking them
Any over counter probiotic should be taken for few days to provide relief in symptoms of indigestion.

Apart from this, some dietary restrictions are to be followed-

- Avoid alcohol or smoking.
- No aerated beverages.
- Take light non spicy easily digestible food for few days.
- No Fast food like pizza or burger should be taken.
- Drink a cup of cold milk daily.
- Avoid fatty foods.


Bloating and acid can be caused by any kind of food. In most of the cases, it's fatty foods which cause these symptoms. Any food whether it's fat or protein or complex carbohydrate when can not be properly digested, releases large amount of gases like hydrogen, methane, carbon dioxide which causes burping.
Hope I've answered your query.
