Hi, Welcome to healthcare magic I have read the query and understand your concern,in my opinion the nauseating feeling,burping and loose motions is most likely due to the infection of gastrointestinal tract called gastroenteritis resulting in indigestion of foods. In such cases I usually suggest my patients to: 1.To drink plenty of water with adequately supplemented electrolytes which replenishes the water and electrolyte loss due to diarrhea,vomiting and prevents dehydration.For this I suggest to mix a sachet of Electral powder in 1 liter of water and have it after each episode of diarrhea,vomiting. 2. tab.ciproflox-tz combination for it to take care of bacterial as well as amoebic infection. 3.Antacid like cap.omeprazole in the morning empty stomach will help relieve the acidity 3. Avoid eating spicy and oily foods for some days, soft foods like rice,fruit juices,soups preferred which are easy to digest. 4.Appropriate rest is very essential for a good immunity to fight against the infection. 5.Eat adequately, there is a wrong misconception that decreased food intake will reduce the diarrhea,in fact it leads to worsening of condition. Don t worry you will be fine in few days by following the above measures. Kindly rate my answer if you find it useful.Feel free to ask any further queries.Take care. Regards, Dr. Tushar Tamboli
