“Doctor, it’s been two months since my gastric sleeve surgery… and I haven’t taken my
vitamins. But I feel fine. Do I really need them?”
That’s a question I hear more often than you might expect. And while the answer might seem
simple, the truth is more serious than it appears on the surface.
Why Vitamins Matter After Bariatric Surgery
Bariatric procedures like the gastric sleeve and gastric bypass change more than just your
stomach size. They change the way your body absorbs nutrients—sometimes drastically.
What Many Patients Don’t Realize:
Even though the gastric sleeve is primarily a restrictive procedure (reducing how much food you
can eat), research now shows it also reduces nutrient absorption. Key vitamins and minerals
affected include:
- Calcium
- Iron
- Vitamin B12
- Folate
- Fat-soluble vitamins (A, D, E, K)
This means that even if you feel fine in the beginning, your body might already be running on
nutrient reserves—and those don’t last forever.
What Happens If You Stop Taking Supplements?
Skipping your supplements doesn’t lead to immediate symptoms. That’s what makes it so
dangerous.
Over time, vitamin and mineral deficiencies can lead to:
- Weak bones or early osteoporosis
- Brittle teeth
- Fatigue and low energy
- Anemia
- Memory problems and mood changes
- Weakened immune system
If you had a gastric bypass, the risk is even higher. This procedure bypasses part of the small
intestine, where many nutrients are absorbed. Without supplementation, malnutrition can
develop quickly—even if you’re eating a balanced diet.
The Lifelong Commitment You Didn’t Expect (But Need)
Bariatric surgery is a powerful tool—but it’s not a one-time fix. Supplementation is a lifelong
commitment, just like staying hydrated and prioritizing protein.
Whether you’re two months post-op or two years, taking your vitamins every day is nonnegotiable.
Takeaway: Don’t Wait for Deficiency Symptoms
By the time you feel something’s wrong, it could already be too late to reverse some of the
damage. Consistency with supplements is what keeps you strong, energized, and thriving in your
new post-op life.
