Hi,
Thanks for posting your query.
With the available described details, there appears to high possibility of Acute
viral gastroenteritis.
You should consult with internal medicine specialist/ gastroenterologist and should go for thorough check up.
You should go for
complete blood count,
erythrocyte sedimentation rate,
ultrasound imaging, and serum electrolytes, renal function test.
You should take complete antibiotic therapy, antispasmodics, probiotics, antipyretics, if needed.
Whenever a patient comes with above mentioned symptoms, then generally 1st diagnosis is gastroenteritis. If your condition won't improve with antibiotic then only non infectious cause should be suspected.
Frequent watery diarrhea and vomiting may cause weakness due to loss potassium.
You should maintain your hydration status by taking potassium rich liquids.
