Thank you for the information,
By your history it seems that you may have the condition which in medical terminology is called Irritable Bowel Syndrome or IBS though you do not have the typical all the symptoms.
Symptoms of IBS-
- abdominal pain,
- diarrhea etc.
The exact cause of IBS not known. It is usually diagnosed by exclusion of other disease.
In most cases no cause is detected. It may be precipitated by -
- certain foods
- low immunity to fight infection
Some dietary measures can help.
Avoid foods that may make diarrhea worse-
- milk products,
- sugar rich foods,
- fatty foods,
- gas-producing foods like beans, cabbage, radish, broccoli etc.
- alcohol etc.
Other common causes of unusual bowel habit are-
- inflammatory bowel disease
- malabsorption syndrome
- polyp etc.
IBS though causes discomfort, does not cause any organic damage to gut.
You should consult doctor to exclude other causes.
I hope this information will be helpful.
Please ask if you need any clarification.
