I am 25 years. i weigh 224 an i am thinking about doing a gastric bypass to lose weight. do u think that's a good choice for me?

Would need to know: Your bmi and lean/fat body composition, but generally speaking unless you are 4ft 10inches, 224 lbs is not gastric bypass territory. At most perhaps lap band but would recommend diet and exercise.

Gastric bypass: That depends on your height. If you are 5'3" and have no medical problems, you would qualify. If you are 5'7" and have medical problems like diabetes, high blood pressure, sleep apnea, asthma, gerd, etc., you would also still qualify. It is all dependent on your body mass index (bmi). You need a bmi greater than 40 if healthy, or greater than 35 if you have medical problems.
