Will IBS reduce the effectiveness of my contraceptive pill?

abbiedarlin1 asked:
I have irritable bowel syndrome. In my form, i have lots of diarrhoea throughout the entire day most days. It’s at random times and not at the same times each day. Wondering if all this diarrhoea from IBS makes my contraceptive pill less effective? If it does, by how much?

Yes it’s likely to make it less effective if you get diarrhea within 1/2 an hour of taking it. Otherwise it should be absorbed.
I am a Gastroenterologist and I can assure you that your IBS will have no affect on the absorption of your contraceptive pill. This is because absorption is not an issue in IBS patients, whether IBS-D or IBS-C.
If you do develop malabsorption problems then the diagnosis of Irritable Bowel Syndrome is wrong.
