Risks of Bariatric Surgery
Bariatric surgery can transform your life.
But like any major surgery, it carries risks.
Knowing these risks can help you make an informed decision — and protect your health.
Here’s a simple, clear look at the top 10 risks of bariatric surgery and smart ways to minimize them.
1. Infection Major Risks of Bariatric Surgery
Risk:
Infections can happen after any surgery, including bariatric procedures.
How to minimize:
Follow all aftercare instructions.
Keep your incisions clean.
Take prescribed antibiotics if needed.
2. Blood Clots
Risk:
Blood clots, especially in the legs (deep vein thrombosis), are a serious concern.
How to minimize:
Walk around as soon as your doctor allows.
Wear compression stockings.
Stay active during recovery.
3. Nutritional Deficiencies
Risk:
Some surgeries, like gastric bypass, change how your body absorbs nutrients.
This can lead to vitamin and mineral deficiencies.
How to minimize:
Take daily supplements.
Attend regular follow-up appointments.
Eat a balanced diet recommended by your dietitian.
4. Dumping Syndrome
Risk:
Eating sugar-heavy foods too quickly after surgery can cause nausea, vomiting, or diarrhea.
How to minimize:
Eat small, slow meals.
Avoid sugary foods and drinks.
Follow your bariatric meal plan closely.
5. Gallstones
Risk:
Rapid weight loss after surgery can trigger the formation of gallstones.
How to minimize:
Some patients are prescribed medication to prevent gallstones.
Gradual weight loss also helps.
Stay hydrated and follow your nutritionist’s advice.
6. Bowel Obstruction
Risk:
Scar tissue or hernias can cause blockages in the intestines after surgery.
How to minimize:
Report any unusual pain, bloating, or vomiting immediately to your doctor.
Early intervention can prevent bigger problems.
7. Leakage from Staple Lines
Risk:
If the staples or sutures in your stomach don’t heal properly, leaks can happen.
How to minimize:
Choose an experienced, board-certified surgeon.
Follow strict post-op guidelines on eating and activity.
Don’t rush your recovery.
8. Acid Reflux
Risk:
After a sleeve gastrectomy, some patients develop or worsen acid reflux.
How to minimize:
Eat smaller meals.
Avoid lying down right after eating.
Your surgeon might suggest medication or further evaluation if needed.
9. Psychological Challenges
Risk:
Rapid physical changes can bring emotional challenges like depression or anxiety.
How to minimize:
Get mental health support before and after surgery.
Join a support group.
Talk openly with your care team about how you’re feeling.
10. Weight Regain
Risk:
Some patients regain weight years after surgery if they return to old habits.
How to minimize:
Commit to long-term lifestyle changes.
Stick to healthy eating and regular exercise.
Attend follow-up visits to stay on track.
