After Gastric Bypass, Does the Stomach Enlarge?

Although it is necessary to learn the stomach anatomy completely for a clear answer, we can say yes as a short answer. However, this does not mean that your stomach will grow. If the patients are fed in accordance with the diet and continue their lives in a healthy way, the stomach will of course not expand.

However, if the patients cannot be fed in accordance with the diet and eat binges, if they continue the desire to snack at night from time to time and make it a habit, the constant filling of their stomach will cause permanent stomach enlargement. Gastric enlargement, of course, does not include the period of the stomach in its original state. However, your stomach may become enlarged permanently after surgery.
