After the birth, the varicose veins usually recede, as the pressure of the previously enlarged uterus on the veins in the small pelvis is relieved and the hormonal changes also return to normal.

The tension in the vein walls increases again and their relaxation decreases. However, even after the birth, some valves may no longer close properly as a result of the prolonged strain. If there are additional risk factors such as obesity, lack of exercise, an inherited "weak connective tissue", a predominantly standing or sedentary job, etc., the varicose veins may reappear after some time. Regression is no longer possible in these cases.
