What Happens if You Don't Take Vitamins After Bariatric Surgery?

Life after bariatric surgery demands a lifelong commitment to nutritional well-being. Prescribed vitamins are the cornerstone of this journey. This section explores the critical consequences of overlooking vitamin supplementation post-surgery.

Iron Deficiency

Our findings show that iron deficiency after bariatric surgery is a common but often preventable complication. It can lead to anemia, characterized by fatigue, weakness, and pale skin.

Iron is crucial for producing hemoglobin, a protein in red blood cells that carries oxygen throughout the body. A deficiency can significantly impact energy levels and overall health.*

Moreover, it can exacerbate the risk of infections and impair cognitive functions.

To prevent iron deficiency, it's vital to adhere to a supplement regimen. Our Cherry Bariatric Iron Soft Chew with Vitamin C offers a convenient and tasty solution to meet your iron needs after bariatric surgery, ensuring optimal absorption and supporting your overall health.

B Vitamin Deficiency

B vitamins, including B12, folate, and thiamine (vitamin B1), play significant roles in the body's metabolic processes.

Deficiencies can result in a variety of health issues, including neurological problems, fatigue, and mood changes.

They can cause symptoms like:

  • Numbness
  • Tingling in the hands and feet
  • Difficulty walking
  • Cognitive disturbances

Folate and thiamine deficiencies can similarly impact the body's ability to produce energy from food, leading to increased fatigue and weakness.

Incorporating the best B12 supplement for bariatric patients into your daily routine can help mitigate the occurrence of these deficiencies.

Calcium & Vitamin D Deficiency

Calcium and vitamin D deficiencies can lead to weakened bones, increased risk of fractures, and conditions like osteoporosis.

Calcium is vital for building and maintaining strong bones, while vitamin D is essential for calcium absorption. Without adequate levels of vitamin D, calcium cannot be absorbed effectively, compounding the problem.*

To combat these deficiencies, patients are advised to take calcium after bariatric surgery. Vitamin D supplements are also recommended.

Indicators of Vitamin Deficiency

Symptoms can vary widely but often include fatigue, weakness, mood changes, and physical symptoms like hair loss (explore our top vitamins for hair loss after gastric sleeve), brittle nails, and skin changes.

Lack of vitamin B12 may lead to neurological issues like:

  • Paresthesia (tingling sensation)
  • Numbness
  • Coordination disturbances

Bariatric Vitamin Requirements

This section dives into the essential bariatric vitamins and minerals needed to support recovery, promote long-term health, and prevent nutritional deficiencies.*

Gastric Bypass

It's essential for gastric bypass patients to take a high-potency multivitamin that includes iron, folate, and vitamin B12. A bariatric-specific multivitamin should be taken daily to ensure adequate nutrient levels.

Given the reduced capacity to absorb nutrients, calcium citrate with vitamin D supplementation is also recommended as an additional supplement if your multivitamin doesn't already contain these essential nutrients.

What happens if you don

Patients should aim for 1200-1500mg of calcium daily, divided into two or three doses (not exceeding 500-600mg in each dose), to maximize absorption.

These soft chews provide convenient calcium supplementation in a strawberry flavor, making it enjoyable to maintain essential nutrients for post-bariatric surgery patients.

Gastric Sleeve

Our research indicates that, following a gastric sleeve procedure, vitamin requirements must compensate for the reduced stomach size.

A comprehensive multivitamin is key. It should contain vitamins A, D, E, and K, and minerals like iron.

Vitamin B12 supplementation is critical due to the reduced capacity to absorb this vitamin from natural food sources. Similarly, iron supplementation is necessary to prevent anemia.

Gastric Band

For those who undergo gastric band surgery, adhering to a specific vitamin regimen is vital for ensuring optimal recovery and long-term health.

Again, a daily multivitamin is essential. This supplement should include vitamin D for bone health, B vitamins for energy metabolism, and vitamin C for immune support and wound healing.*

How to Avoid Post-Op Deficiencies

Maintaining optimal nutrient levels after bariatric surgery is fundamental to successful recovery and long-term health.

Following a supplement plan tailored to your specific type of bariatric surgery is important. This plan should cover all necessary vitamins and minerals, as your altered digestive system might not absorb efficiently from food.

Similarly, incorporating nutrient-dense foods into your diet is vital. Focus on foods high in vitamins, minerals, and fiber, yet low in calories, to ensure you're getting the nutrients you need without excessive calorie intake.


Through this comprehensive guide, we've dissected the pitfalls of ignoring vitamin supplementation, ranging from the risks of iron, B vitamins, calcium,and vitamin D deficiencies to identifying the early signs of vitamin deficiency.

We've delved into specific needs following gastric bypass, gastric sleeve, and gastric band surgeries and shared actionable strategies to forestall postoperative nutritional gaps.
