Hi.
Thanks for your query.
Noted the history of return from Dominican Republic, got little more regular than usual, you have to visit bathroom within 10 minutes of eating a meal, cramping pains, wants to know whether to be concerned or is this normal.
This is not at all normal.
The causes can be Inflammation of the intestines or other structures in touch with intestines.
Can be IBS that is
irritable bowel syndrome.
I would advise you the following:
Consult a Doctor immediately.
Clinical evaluation, examination and order for investigations of :
Stool, blood and urine.
Ultrasound of the abdomen to start with and
CT scan if
diverticulitis is found out.
A course of an antibiotic,
Metronidazole, probiotics and supportive treatment like multivitamins can helps you to get a cure within a few days.
If not you may need further investigations and management.
