You should consult with internal medicine specialist/ gastroenterologist and should go for thorough check up.
You should take complete antibiotic therapy, probiotics, and antispasmodics.
You should avoid milk and all milk related products.
You should take potassium rich diet such as banana, juice, and coconut water.
