I had been observing stomach pain,cramps,bloating,gas(flatulence) and constipation symptons for close to 18 months and consulted gastroenterology doctor. Underwent couple of gastro intestinal diagnosis(ultrasound of whole abdomen),blood test,Endoscopy of upper intestine. From the diagnosis doctors didn't find any issues and based on the results of diagnosis and symptoms I had shared with doctor, he mentioned that I had IBS(irritable bowel syndrome) and suggested medication to control symptoms,Took those medicines and didn't observe any improvement as such. Also started restricting foods which have an adverse reaction to IBS like reducing lactose and fructose rich foods,milk and increasing fiber intake Please suggest how I can tackle this situation..
