This link if you copy and paste into your browser talks about evaluation/diagnosis of IBS and treatment ideas. https://www.mayoclinic.org/diseases-conditions/irritable-bowel-syndrome/diagnosis-treatment/drc-20360064 A history is where it begins along with a physical and they run tests from there. There are many good treatment options currently but it depends on what type of IBS you have. And one must also factor in diet and psychological effects that impact it.
