Hi,
Thanks for posting your query.
With the available described symptoms, there could be possibility of
gastroenteritis or
intestinal obstruction.
Presence of rumbling sound with
constipation suggests the intestinal obstruction and presence of diarrhea suggests the 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.
Effect of laxative last for few hours and may subsided itself.
You should maintain your hydration status by taking potassium rich liquids.
Take soft diet along with yogurt and banana.
Avoid milk and all milk related products.
Take care,
Dr. Mayank Bhargava
