After gastric bypass or certain other types of weight loss surgery, the health benefits often happen right away. For instance, your diabetes might improve dramatically. The same might be true of high blood pressure, arthritis, sleep apnea, high cholesterol, and other conditions.

What happens to your body after gastric bypass?

Immediately after gastric bypass surgery, you may have liquids but no solid food as your stomach and intestines begin to heal. Youll then follow a special diet plan that changes slowly from liquids to pureed foods. After that, you can eat soft foods, then move on to firmer foods as your body is able to tolerate them.
