Hello, My Aunt In Sweden Has Two Failing Kidney's. I'm

Hello, my aunt in sweden has two failing kidney's. I'm considering donate one of mine. I'm 61, exellent health. All test has come back 100%. My concern is, before I go to Sweden for further tests. I have hypothyroidism since 10 years. I also have an mirco endonoma on my pituritary gland since I was 22. Could these two conditions prevent me from donating.
Thank you very much for your time.
