The following is a list of possible side-effects and complications to consider before having weight-loss surgery. We will discuss these in more detail at your office consultation.
1. Anastomotic leak (leak from a connection made to the bowel, usually requires re-operation and long hospital stay)
2. Anastomotic stricture (narrowing or obstruction at an intestinal connection resulting in vomiting)
3. Bowel obstruction/strangulation/internal hernia/ischemic bowel possibly needing removal (associated with pain and vomiting, usually requires re-operation)
4. Injury to an abdominal or pelvic organ/structure (especially the liver, spleen, pancreas, bile duct, stomach, esophagus, colon, bowel, diaphragm, urinary bladder, nerve or blood vessel)
5. Conversion to an open operation (due to bleeding, poor exposure, large liver, tension on intestines, etc.)
6. Incisional hernia (more likely if procedure is done open)
7. Infection or abscess (due to a leak, spillage of intestinal contents, underlying infection, etc)
8. Bleeding and the potential need for blood transfusion. Blood transfusion carries the risk of infection with bacteria, parasites (malaria), and viruses (hepatitis, HIV/AIDS).
9. Need for additional surgery or procedures to treat any complication that may occur
10. Prolonged hospital stay or readmission may be needed to treat complications
11. Deep Vein Thrombosis (blood clot in a vein)
12. Pulmonary Embolus (blood clot going to lung, fatal 30% of the time)
13. Atelectasis (lung collapse causing fevers, possibly pneumonia)
14. Pneumonia, lung infection and fluid around the lungs (pleural effusion)
15. Heart attack (myocardial infarction)
16. Stroke
17. Pancreatitis
18. Rhabdomyalysis (breakdown of the muscle in the body)
19. Pressure ulcer or decubitus (skin breakdown, may require skin grafting)
20. Allergic reaction to anesthesia, medications or materials
21. Nerve or ligament injury from positioning or lying on the operating table
22. Kidney failure and/or the need for dialysis
23. Need for ICU care
24. Need for a ventilator (machine to help you breathe)
25. Multi-system organ failure (liver, kidneys, lungs, etc.)
26. Poor cosmetic results (ugly scar, keloid, unattractive incisions, contour defects)
27. Chronic pain, discomfort, numbness, burning or tingling in the incisions or anywhere else (abdomen, back, extremities)
28. Transient or chronic nausea/vomiting due to strictures, gastroparesis, food intolerance, etc.
29. Dysphagia (difficulty or painful swallowing)
30. Diarrhea, constipation, foul smelling gas and stools
31. Heartburn (acid reflux) symptoms
32. Ulcers or gastritis
33. Intestinal perforation due to ulcer, foreign body, obstructed food, etc.
34. Development of food intolerances/loss of taste
35. Dumping syndrome (abdominal pain, heart palpitations, sweating, nausea, diarrhea)
36. Hair loss or thinning
37. Development of malnutrition or vitamin deficiency
38. Anemia
39. Metabolic bone disease (loosing calcium from the bone because of inadequate intake and supplementation) with possible osteoporosis, secondary hyperparathyroidism and bone fractures
40. Failure to lose an adequate amount of weight
41. Loss of too much weight
42. Development of loose or redundant skin
43. Sterility or inability to become pregnant
44. Increased ability to become pregnant
45. Birth defects or fetal injury if you become pregnant. This is less likely once weight has stabilized and laboratory tests are normal. Usually, about 2 years after surgery.
46. Postoperative depression or other psychological reaction to surgery
47. Need to revise or reverse the procedure at some point in the future because of nutritional deficiencies, excessive weight loss, pain or other reasons
48. Extended disability, financial hardship as a result of complications related to weight loss surgery
49. Parts of your stomach and/or intestines will be inaccessible by endoscopy.
50. Death (1% nationwide) within 30 days
