Complications & Risks of Bariatric Surgery or Weight Loss Surgery

Surgical mortality from bariatric surgery is generally less than 1%. Risks involved vary with the procedure, patientís age and medical conditions, and the expertise of the operating team.

Males have increased risk for morbidity and mortality compared to females undergoing this surgery.. What follows is a list of the possible complications of bariatric surgery:

Bleeding from the intestines

Infection of the wound

Blockage, tear in the bowels

Food intolerance

Vomiting or straining after surgery before the incision heals can cause a hernia. Laparoscopy assisted surgery greatly reduces hernia risk.


Nutritional consequences: Deficiency of calcium, vitamin D, vitamin B-12, iron.

Gastroesophageal reflux

Hiccups and bloating may occur due to the enlargement of the bypassed stomach


Blood clots in the legs or lungs

Heart attack


Urinary tract infection

Anesthetics problems may occur as in any major operation.

In bariatric surgery a condition called "rapid gastric emptying" or Dumping syndrome can occur. Dumping syndrome occurs when the lower section of the small intestine (jejunum) fills up too quickly with undigested food from the stomach, causing unpleasant digestive effects. Dumping syndrome can also be triggered in gastric surgery patients by consumption of simple carbohydrates (sugar, or some starches) or carbohydrates with a high glycemic index.

There are two variants of rapid gastric emptying: early and late dumping.

Early dumping typically starts during or immediately after a meal with symptoms like:

1. Abdominal cramps

2. Bloating

3. Palpitations

4. Nausea

5. Vomiting

6. Diarrhea

7. Shortness of breath

Late dumping typically occurs 1-3 hours after eating with symptoms like:

1. Weakness

2. Dizziness

3. Fatigue

In addition to my other letter. I also am having trouble with a foot that is going numb. Neruopathy from lack of vitamin b-12 and I am having trouble with my eye sight. I have double vision. they are testing me for mysethina gravis and MS. I am suffering daily all I believe due to the gastric bypass surgery.. I maybe wrong but I was without any of these problems before the surgery.. My dr. once said for being 333lbs. you'd never know it looking at all of my health issues or lack of and lab work. my health status was great I only was fat...I'd do anything to not have done this surgery and have my healthy fat life back...I can't believe I did this surgery so I could do more funny, I suffer daily in pain, losing my teeth, losing feeling in my foot and most of all I have to close my left eye to see or I'll see double vision. that takes away your independence.. OH what I wouldn't do to be a healthy fat functioning independently daily....
