Following a myomectomy, a woman may be left with a drooping belly. The most effective way to address this issue is through exercise. The abdominal muscles have 8 layers, including the skin, fascia, and muscles. These muscles are essential for maintaining a flat stomach and minimizing the “abdominal pouch.” To achieve a flat stomach after a myomectomy, you must follow a healthy eating and exercise regimen. Aim to get at least 20 minutes of aerobic exercise a day.
