Hi there I understand your concern... Diagnosis is very important in irritable bowel syndrome...you will need certain investigations to rule out other causes...investigations are ultrasound abdomen,liver function test,blood tests like complete heamogram,stool examination etc... There is no specific treatment of this disease. It can be controlled by altering diet pattern,psychological therapy and medicines. You can take course of antibiotics containing Ofloxacin and Ornidazole twice daily for five days... try eating several small meals instead of three large ones whenever you can...Avoid foods that irritate your stomach, especially those that are spicy, acidic, fried or fatty... avoid coffee,tea etc... Avoid stress,consider calming activities, such as meditation, yoga etc...sleep with head raised position and have dinner at least 2 hours before sleep...drink plenty of water, add fibre to your diet ..Consult nearest gastroenterologist they will do the needful.
