Gastric sleeve surgery is a permanent surgical procedure, and it is not reversible. It is used as a permanent method to treat obesity by reducing the size of the stomach and modifying the digestive system.

During the surgery, the stomach is significantly reduced in size to form a shape that can accommodate less food. This allows for consuming smaller portions and fewer calories. By altering the digestive system, the absorption of nutrients is partially restricted, leading to weight loss.

After gastric sleeve surgery, a person continues to lose weight by maintaining a new dietary regimen and exercise program along with lifestyle changes. However, the process of post-operative weight loss is entirely dependent on the individual, and since the surgery is irreversible, it is not possible for the pre-operative weight to return.

Nevertheless, there can be challenges in weight control after gastric sleeve surgery in certain cases. For example, not adhering to post-operative lifestyle changes, reverting to unhealthy eating habits, or not engaging in exercise can affect weight loss. Therefore, it is important for the individual to regularly attend doctor’s appointments, seek support from a dietitian, and maintain healthy lifestyle habits for the post-operative process to be successful.

Gastric sleeve surgery is an irreversible surgical method that, along with lifestyle changes supporting weight loss, provides a lasting impact. However, the success of the post-operative process and the maintenance of weight loss are contingent on the individual.
