What are the different types of weight loss surgeries?

ANSWER

Restrictive surgeries work by shrinking the size of the stomach and slowing down digestion.

Malabsorptive/restrictive surgeries change how you take in food. They give you a smaller stomach and also remove or bypass part of your digestive tract, which makes it harder for your body to absorb calories.

Implanting an electrical device, the newest of the three techniques, prompts weight loss by interrupting nerve signals between the stomach and the brain.
