Could a surgical abortion cause permanent damage? is it possible for a professional surgical abortion to cause my body permanent damage?

Yes, but...: One uncomplicated abortion very rarely causes damage or gives later fertility problems. A good obg or fertility doc can help evaluate you if you have concerns.

Avoid complications: Yes, with all surgical procedures there is risk for complication; bleeding, infection, recurrence, scarring. During consenting these possibilities are discussed, the risk/benefit analysis. Only after consent, is a procedure performed. If you are not well after your surgery, contact your doc. If you have fever or vomiting get in right away.
