I am currently in the process of fulfilling all of the requirements to have gastric bypass. I went to my GP for surgery clearance and he had some concerns. I have MCAS and I have issues almost on a daily basis with being nauseous and foods not agreeing with me due to my MCAS. He was wondering what it would be like for me post surgery. He is not opposed to the surgery. He says it is my decision and without MCAS he is all for it. He believes I will benefit from it. He just wants me to reach out to the community and see if anyone with MCAS has had the surgery before. Since the surgery can't be reversed it is best to make sure it will not hurt me before hand. So do any of you have MCAS (diagnosed prior to your surgery)? What was it like for you prior and post surgery? Has it helped or made it worse?

actually, RNY CAN be reversed, but it's a complicated surgery and they only do it if someone has severe medical issues that can't be resolved any other way.
