Is it possible to have scar tissue from a natural miscarriage? i'm having a hysteroscopy and my doctor said she suspects it might be ashermans syndro

Asherman's syndrome: Asherman's syndrome can be caused by extensive scarring of the lining of the uterus, usually as a result of serious infection. A "natural" miscarriage is not generally associated with such. It is unlikely that Asherman's is present, especially if you are now having fairly normal periods (3-5 days if not on oral birth control).

Natural miscarriage: If you had a natural miscarriage without a surgical D & C procedure to follow, then Asherman's syndrome is an exceedingly rare occurrence Hysteroscopy will provide insight into the possible cause of any scar tissue if seen.

Yes : Sometime you can develop scar tissue from curettage ,so anyway hysteroscope is a good way to evaluate
