I would be careful. We were well on our way to adopting - in the midst of a home study - and we ended up with a crummy social worker (nice lady, but oblivious) from a really well known and reputable agency. She ended up telling us she thought our chances of adopting were 50-50. I had disclosed my health issues, mostly in the context of how it brought my husband and I closer together. And I had a perm ileo at the time and no health problems at all.
We were subsequently told that the social worker should never have said that, that she was wrong, we would have most certainly been able to adopt. However, we got totally scared and opted to try IVF since the chances of success there were 40% and in our state it was 100% covered by insurance - our decision to adopt would have cost us a lot more. We wanted to do that and were committed to it but really got spooked by that person.
In the end we were really lucky with IVF - pregnant three times, first try each time, two live births. But I still think about adoption - if I were younger and had more financial resources, we might adopt, but as it is, we are settled as a family of 4.
Moral of the story - be sure you find an agency AND social worker you trust.
