According to a study1 by WebMD, about 10% of gastric bypass patients face postoperative complications that are usually not severe. There are certain lifestyles changes that one can make to minimize bariatric surgery risks.

Gastric Bypass Risks and Complications

1. Abdominal Pain

This is one of the most common side effects of gastric bypass, as more than half of the patients complain of post-operative abdominal pain.

There can be many causes for this and it is best to get yourself examined and find out the root cause. Rapid eating, intolerance to certain foods, irritable bowel syndrome, dumping syndrome, and ulcer disease are some of the reasons for abdominal pain.2

2. Nutritional Deficiencies

Nutritional Deficiencies

Since gastric bypass involves manipulating the gut, it leaves the body deprived of essential vitamins and minerals. According to a 2005 study conducted by Bloomberg and colleagues, and published in the Obesity Surgery journal,3 gastric bypass may result in the deficiency of:

  • Vitamin B12
  • Folate
  • Zinc
  • Iron
  • Copper
  • Calcium
  • Vitamin D

This may further result in:

  • Osteoporosis (Calcium deficiency)
  • Wernicke encephalopathy
  • Anemia (Iron deficiency)
  • Peripheral neuropathy
  • Fatigue

Prevention/Remedy

  • Take small meals.
  • Choose foods that are dense in nutrients.
  • Ensure 60 grams of protein in your diet every day.
  • Supplements
  • Calcium Citrate with Vitamin D, Vitamin B-12 and Iron should be taken regularly for protein deficiency.
  • Know the symptoms for nutritional deficiencies after gastric bypass.

3. Leakage

Leaking of gastric juices or acids through the staple line or sutures is another problem that may be encountered after a gastric bypass procedure. Gastric leaks may cause harm to nearby organs and tissues.

According to a January 2009 study approved by the ASMBS Executive Council, “gastrointestinal leak after gastric bypass is a known complication with a reported incidence between 1 and 5% in large case series of open and laparoscopic gastric bypass.”4

Prevention/Remedy

  • Using the right size of staples.
  • Over-sewing, either by hand, or by stapling devices.
  • Use of biological hemostatic or coagulating agents to prevent or stop leakage.

4. Ulcers/Blood Clots

In rare cases, gastric bypass patients may also experience ulcers in the stomach or the intestinal lining, as well blood clots in the lungs or legs.

Prevention/Remedy

  • Ulcers in the stomach or the small intestine can be cured by antibiotics.
  • Blood clots in the lungs or abdomen can be cured by anticoagulant medicines.

5. Gallstones

Gallstones

Gallstones are clumps or chunks of cholesterol and other similar matter that deposit in the gallbladder while or after quick and significant weight loss.

According to a report by the Bariatric and Metabolic Institute, Cleveland Clinic, nearly 33% of individuals who have had gastric bypass develop gallstones.5

Prevention/Remedy

According to the Cleveland Clinic, bile salt supplements should be taken for 6 months after the surgery to prevent gallstones.

6. Surgical Site Infection

A study conducted among 115 bariatric patients found that the chance of wound infection on the incisions is very less.6 If the procedure has been done laparoscopically, the chance of an infection is even lesser. 9 out of 10 people do not experience any such complications.

7. Bowel Obstruction due to Internal Hernia

One of the most common complications after laparoscopic gastric bypass surgery is bowel obstruction due to internal hernia.7

Prevention/Remedy

  • Quit smoking
  • Maintain a healthy body weight
  • Avoid straining during urination or bowel movements
