Hi, Welcome to health care magic, Stomach upset or discomfort with vomiting feeling (nausea) is a commonest symptom among people seen nowadays. Can you tell me since how many days you are facing this problem and is there any specific diet after which you troubled stomach. Also feeling weakness and little shaky could be related to your anemia (low blood as you said) which should be investigated accordingly. The causes of stomach upset could be acute gastritis, gastroenteritis or Helicobacter pylori infection which needs to be further investigated. So,you must undergo routine blood investigations and H.pylori,liver function tests,urinalysis and stool for blood (to rule our recurrent amebiasis) and abdominal ultrasound to detect the underlying cause. Treatment is mainly depend on the cause but you should take symptomatic treatment meanwhile like 1) Antacids like h2 blockers (ranitidine) or proton pump inhibitors (pantoprazole or rabeprazole) will help to reduce excess acid production in stomach. 2) You can also take digene gel or liquid or ulcero-protective agents like sucralfate or bismuth subsallicylate to reduce the burning sensation. 3) Take albendazole for de-worming after your blood and stool tests but you will need prescription for that. Apart from medications you should also try some non-medical or dietary measures which are: 1) eat plain foods like boiled rice and green leafy vegetables without adding spices or oil. It will help to neutralize digestive acids and also they are easily digestible means there will be no need of extra stomach acid. 2) avoid oily,spicy and fast foods 3) avoid eating full stomach at a time rather have small meals frequently. 4) drink coconut water will help to reduce burning. 5) eat lots of fruits like banana and watermelon. You must see gastro physician who can examine you properly and prescribe the treatment. Regards,
