Asherman's syndrome is inflammation of the lining of the uterus caused by scar tissue in the walls of the uterus. This is an uncommon condition that can cause changes in the menstrual cycle and can lead to miscarriage or infertility.

The scar tissue that causes Asherman's syndrome may form after surgery on the uterus, such as dilation and curettage (D&C) or after an infection of the uterus, such as tuberculosis or schistosomiasis. In some cases, this condition may cause increased pain or cramping during the menstrual cycle. And menstrual bleeding may decrease, or periods may stop completely.

Asherman's syndrome is treated with surgery to remove the scar tissue.
