Hi,
Thanks for posting your query.
With the available described details, there could also be possibility of acute
viral gastroenteritis.
Headache and
dizziness could be prodromal symptom of viral infection.
Dizziness could also be due to fatigue caused by pottasium loss in recurrent
vomiting.
You should consult with internal medicine specialist/ gastroenterologist and should go for thorough check up.
You should also go for
complete blood count, urine routine microscopic examination, and serum electrolytes, renal function test.
You should take complete antibiotic therapy, antispasmodics, anti-emetic, probiotics, antipyretics, if needed.
You should maintain your hydration status by taking potassium rich liquids.
Frequent diarrhea/ vomiting may cause loss of potassium with weakness and fatigue feeling.
Take
soft diet along with yogurt and banana.
Avoid milk and all milk related products.
Take care,
Dr. Mayank Bhargava
