What is the down side to gastric bypass?

What is the down side to gastric bypass?

Potential risks: Gastric bypass is a major surgery - never to be approached casually. As with any major surgery, there exist complications - even the possibility of dying! on the other hand, when a person has multiple "co-morbidities" of obesity (diabetes, high blood pressure, sleep apnea, etc.), the benefits may outweigh the risks. Talk to your doctor, your family, and yourself as you make this important choice. ...Read more

Is there a diet that I can go on to shrink my gastric bypass pouch back down to the size that it was. Have lost over 200+ want to go another 50 lbs. ?

Is there a diet that I can go on to shrink my gastric bypass pouch back down to the size that it was. Have lost over 200+ want to go another 50 lbs.  ?

Probably not: Diet alone will not shrink the pouch. However, limiting your portion sizes should help. Be sure you are limiting high fat foods and carbohydrates. Most people eat too much of these. If you limit them you should lose weight. Also, are you exercising? If you walk daily it should help with weight loss. Be sure to talk with your doctor about a good goal weight. Good luck! ...Read more

I am a 28yo woman, 2yr.Post op gastric bypass. I am often nauseas & go days vomiting keeping.Only liquids down.What could be the cause? Dr says im fine

Possible stricture: If the nausea and vomiting have been occuring since surgery it may be your gastric pouch was made to small. If the symptoms are more recent, there is the possibility of an anastomotic stricture or marginal ulceration. Evaluation of the bypass anatomy with an upper endoscopy or an UGI study would be appropriate. ...Read more

Diagnosed me with bile induced gastritis. Wants to do a gastric bypass. In my 40's,(5'4", 203), but isn't there a less invasive answer?

Diagnosed me with bile induced gastritis. Wants to do a gastric bypass. In my 40's,(5'4", 203), but isn't there a less invasive answer?

Options: Probably theist popular weight loss operation at the moment is a sleeve gastrectomy. Its not really less invasive, but has less potential for long term side effects. There are also some newer endoscopic therapies, but they are not so effective. Ask your doctor if a consultation with a Bariatric surgeon is appropriate. Hope this helps! ...Read more

S/p gastric bypass sugery by you 12/2010. I have a high pth level w/low calcium levels , 4 tests all high, can this be parathroid cysts? Scan was ?

High PTH low ca: This condition is due to your gastric bypass. Calcium and vitamin D are absorbed in the small bowel. This is now bypassed. The PTH is elevated due to low calcium absorption and likely low vitamin D. This can be corrected medically, but in rare cases the bypass had to be reversed to correct the condition when it resulted in severe hypocalcemia. ...Read more

Clean is good: If you mean a 10 day meal replacement with a balanced low sugar shake like medifast or glucose-controlled boost (plus all vitamins) it should be ok. However, the best diet to work with a bypass is a solid meal (protein and veggies) with no sipping, fewer slider foods, no sweets and no bad snacks.

What possibility does a 24 year old woman have of skin sagging after gastric bypass?

Depends on Weight: This depends on the starting weight of the patient. At 24, you skin is definitely more elastic than a 60 y.o., and some of it will retract back to "normal". But ultimately it depends on the size of the person before the bypass, and the weight lost after. The more the skin is stretched before the surgery, and the more weight loss, the more skin will sag. ...Read more
