Can a woman who has lupus deliver a baby without medical intervention?

Yes!! I have lupus and had two beautiful children with little complication. I did have toxemia the last month of my second pregnancy, but my doctor said it wasn't necessarily from the lupus. My first was induced and I had an epidural. The second came so fast that I didn't need to be induced and there was no time for an epidural! They are both healthy. I had no side effects from my pregnancy that aggravated my lupus. I also nursed both of my children with no problems. I think the biggest issue with pregnancy and lupus is actually trying to conceive and making it past the 12 week mark. I had 2 miscarriages , 1 before each of my successful pregnancies. That was difficult but after each was born I came to understand why it happened that way. Good luck to your loved one.
