The crotch can be changed back after it is closed. Especially for the false hip breadth caused by bad living habits, such as incorrect sitting posture, you can shrink back and forth through active exercise and posture adjustment. However, for the real hip breadth, that is, hip breadth caused by the change of bone structure, it may not be fully recovered after the hip joint is closed, because the bones have been shaped and it is difficult to change through exercise.

If you want to prevent the crotch from swelling, it is recommended to maintain a correct sitting posture and standing posture, avoid sitting or leaning to one side for a long time, and do appropriate exercises, such as yoga and swimming, to strengthen the muscles of the waist and buttocks, so as to stabilize the pelvis and prevent the crotch from swelling.

Please note that if you have health problems about body parts, it is recommended to consult a doctor or professional health care personnel.
