Vitamin and Mineral Absorption Problems After Gastric Sleeve Surgery

Sleeve gastrectomy is a bariatric surgery procedure that reduces the size of the stomach and promotes weight loss. After this surgery, nutritional intake decreases, and absorption of some vitamins and minerals may be inadequate. Long-term deficiencies can lead to serious health problems.

Vitamin and Mineral Deficiencies After Gastric Sleeve Surgery
1. Vitamin B12 Deficiency
Why? Because the stomach shrinks, the production of intrinsic factor, which is necessary for B12 absorption, decreases.
Symptoms: Fatigue, forgetfulness, depression, numbness in the hands and feet
Solution: B12 supplements (pills, sublingual tablets, injections)
2. Iron Deficiency
Why? Iron absorption becomes more difficult due to decreased stomach acid.
Symptoms: Weakness, pale skin, hair loss, dizziness
Solution: Taking iron supplements with vitamin C increases absorption. 3. Vitamin D and Calcium Deficiency
Why? Calcium absorption decreases due to inadequate nutrition and decreased stomach acid.
Symptoms: Bone pain, risk of osteoporosis, muscle weakness
Solution: Vitamin D and calcium supplements (calcium citrate form is recommended).
4. Folic Acid (B9) Deficiency
Why? Decreased food intake and malabsorption
Symptoms: Anemia, pale skin, nervous system problems
Solution: Multivitamins containing folic acid
5. Zinc and Magnesium Deficiency
Why? Insufficient intake due to restricted diet
Symptoms: Hair loss, weakened immune system, muscle cramps
Solution: Supplements containing zinc and magnesium
Recommendations for Vitamin and Mineral Supplements After Gastric Sleeve Surgery

✔ Multivitamin Use: At least 1-2 multivitamins should be taken daily.
✔ Regular Blood Tests: B12, iron, and vitamin D levels should be monitored.
✔ Healthy Diet: Prioritize protein, vegetables, and healthy fats.
✔ Doctor’s Checkups: Precautions should be taken before symptoms of deficiency appear.

To prevent vitamin and mineral deficiencies after gastric sleeve surgery, regular supplementation and a healthy diet are vital.
