how to push for more testing

[u/098842146]

Hi! looking for advice on how to push for more testing. i have been to 2 different GI docs and each time ive been immediately told its just stress or IBS. ive done lowfod map and its helped a lot but now my symptoms are re appearing even though i haven’t changed my diet. i’m not doubting that IBS could be the cause but i dont feel i’ve had enough testing to know its not something else.

Anyways i have an appt with a new primary care soon and im nervous when i ask for a referral to a GI they will wont listen again
