Varicose Veins+Steroid Inhalers=Poor Healing?

I've been really scrounging for information about my upcoming sleeve surgery. I'm self pay, heading to Mexico and want to learn as much as I can in hopes that I heal as well as possible without complications. I found an article on bariatrictimes.com that explained how the stomach healed after surgery. I've always loved science, and biology so even though it was a bit technical I was intrigued with the details. Without quoting the whole study, one of the things that I learned was that the best healing takes place in the presence of good blood supply.

I have varicose and spider veins in my legs. I'm wondering if anyone thinks this may mean I could potentially have poor blood supply in other areas of my body, namely my stomach??

Also, I have used steroid inhalers for my asthma for better than 20 years. I'm supposed to rinse and spit out the Water after use, but sometimes I just take a drink and swallow it. Am I swallowing enough medication that it may change how my stomach heals after surgery??

Any sleeved nurses out there that could comment on that?

I have the option of a phone consult with my surgeon, but I don't want to seem like "the crazy lady with the hair-brained questions", even though I really am coming up with some random, oddball thoughts of late!
