Which is safer and more effective: gastric bypass surgery or liposuction?

I have many friends and family who got a gastric bypass surgery and it looks great, but on the other hand, liposuction seems more convenient for wanting to really lose weight. I wanna know which process would be safer and more effective in losing weight.

Liposuction is not a way to lose weight. Whoever told you that is wrong. Liposuction is used to get rid of fat in a specific area of the body that no matter how much weight the person loses, this extra fat does not go away. The only way to get rid of it is to use liposuction.

Gastric bypass is used as a last resort for people that need to lose a lot of weight (usually 100+pounds). The two things are totally different as to what they do. If someone needs to lose over 100 pounds, liposuction would be useless for accomplishing that. You would have to poke holes all over their body and suck out fat from everywhere which would most likely kill them. If not, then they would just gain it back when they continue to eat as before. Gastric bypass creates a small pouch and bypasses the stomach leaving only a very tiny pouch stomach making it impossible to eat like before which creates the huge weight loss results. It also takes away the feeling of hunger after eating just a small portion of food which works perfect for those that overeat and never feel full. Liposuction does none of that.
