How Long After Sleeve Surgery Can I Smoke (And Why)?

Exact Answer: Never (Ideally)

Sleeve surgery, also known as vertical sleeve gastrectomy, involves removing eighty percent of a person’s stomach. This surgical procedure reduces the size of the stomach and induces weight loss by restricting food intake.

By altering the anatomy of the gastrointestinal tract, sleeve gastrectomy changes signals in the body resulting in decreased hunger and increased feelings of fullness after meals which results in the weight loss process.

The surgery involves small incisions on the abdomen region, through which surgical instruments enter the abdominal cavity. The surgeon may employ the use of general anesthesia. Now, the surgeon divides the stomach into two unequal parts. The surgeon now removes the larger part of the two and the smaller part, which is the size of a banana, functions as the new stomach.

The surgery in itself is minimally invasive, and therefore recovery is quick. Proper precautions need to be employed to avoid any complications.
