Hi
I have gone through your query.
Based on the information I feel you have
gastroenteritis.
Most cases of gastroenteritis are caused by viruses and requires only symptomatic treatment, consuming contaminated foods or drinks is another common cause.
You do not need antibiotic and also not anti diarrhoeal agent.
I would suggest you to drink plenty of water or electrolyte solutions to prevent
dehydration.
Add bland foods to your diet, such as bananas, toast, oatmeal and rice in small amounts every couple of hours. Avoid spicy food. Restrict meat for few days.
You can take curd which will be beneficial.
You can take capsule
omeprazole 20 mg before breakfast, empty stomach once daily for a week. Probiotics like sporolac or ecobion will be beneficial.
If the above measures doesn't help, i would have asked for stool routine examination and based on the report I would have decided on the next line of management (requirement of antibiotic)
Hope this helps
Take care.
