I can understand your concern.
first of all, we should be diagnosing if its candida or not.
so, you should have mentioned your symptoms here rather than your own diagnosis because 99 out of 100 times, your diagnosis will be wrong.
a learned person diagnosed you with IBS and you are questioning his diagnosis based on your own diagnosis when you do not have one percent knowledge also about how the diseases work.
just consult a gastroenterologist and let him do the diagnosis part.
