At present, the main method to treat U-shaped pregnancy, U-shaped stretching and U-shaped stria is laser therapy. Different devices have different effects, but the timing of treatment is more important. The earlier a pregnant woman is pregnant, the better the curative effect. It is better to start treatment one week after delivery, and it will be more difficult to treat if it takes too long. Generally speaking, half a year after delivery is the golden period of treatment, and it is better to choose a professional hospital than a small clinic.
