Will wrapping belly after delivery helps to reduce belly size? There’s no evidence that a belly wrap will help you lose weight. While you may be down a few pounds after using one, this is mainly due to water loss. As soon as you hydrate and eat, the number on the scale will go right back up. The only proven way to lose weight is through proper diet and adequate exercise. ❇️Real benefits of Postpartum Belly Wraps❇️ 👉🏼Helps relieve pain 👉🏼Helps you get moving 👉🏼Helps increase blood flow 👉🏼
