Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that diarrhea, vomiting, fever and weakness seems to be due to
stomach infection that can be due to bacterial infection,
Viral Gastroenteritis or Parasitic infestation..
As it is already 2 weeks I would suggest you to
consult a Gastroenterologist and get evaluated and a thorough clinical evaluation and investigations like Stool tests, blood test etc can help in diagnosis and treatment can be done accordingly..
As of now you can be advised to take fluid replacement therapy that is drinking plenty of oral rehydration solution..
You can take
Acetaminophen for reducing fever..
You can also take Loperamide to reduce loose motions and Ondensarton to relieve Vomiting and nausea..
You should take probiotics like Yoghurt, rice, cereals and banana in diet..
In case of bacterial infection you can be advised antibiotics and anti parasitic medication like
Albendazole for parasites..
Hope this information helps..
Thanks and regards.
