Hello,
Welcome to Healthcaremagic.
From your query i suspect that you may be suffering
Irritable bowel syndrome (IBS) or chronic
functional abdominal pain.
IBS patients usually suffer from worse abdominal pain in morning.Because colon is more active in morning.
It is not final diagnosis.
But you have to do further investigations to rule out any abdominal infections.
The following investigations may be helpful.
Complete blood count- To rule out anemia from parasitic infections
WBC count to rule out infections
ESR-
Erythrocyte sedimentation rate - To rule out any inflammation
Antibody testing to rule out coeliac disease
Colonoscopy and endoscopy to rule out any pathology in gastro intestinal tract.
To rule out liver and gallbladder disease, liver function test and
lipid profile.
To rule out kidney disease, do urinalysis, urea, creatinine and urine culture.
Hope this helps.
Take care.
