Hi,
Welcome to health care magic,
Stomach pain,bloating with nausea just after eating could have many causes which are
acute gastritis,gastric ulcer or
Helicobacter pylori infection or
food allergy or stress.
Your daughter should undergo routine blood investigations and H.pylori,liver function tests,urinalysis and stool for blood,abdominal ultrasound and upper gastrointestinal endoscopy to detect the underlying cause.
Treatment is mainly depend on the cause but she may take symptommatic treatment meanwhile.
Antacids like h2 blockers (ranitidine) or proton pump inhibitors (
pantoprazole or rabeprazole) will help to reduce excess acid production in stomach.
One can also take digene gel or liquid or ulcero-protective agents like sucralfate or bismuth subsallicylate to reduce the burning sensation.
Apart from medications she should eat plain foods like boiled rice and green leafy vegetables without adding spices or oil. It will help to neutriluze digestive acids and also they are easily digestible means there will be no need of extra stomach acid.avoid oily,spicy and fast food
Consult gastroenterologist for detailed medical history and clinical examination to diagnose the cause.
Thanks and Regards,
