key visual screening after gastric sleeve

The nutritional status of patients 5 years later: why nutritional screening after a Gastric Sleeve is essential

The Gastric Sleeve, or Sleeve Gastrectomy, has become the most frequently performed bariatric procedure worldwide. Postoperatively, patients are at risk of developing micronutrient deficiencies, due to limited oral intake, food intolerances and malabsorption. To assess the need for nutritional screening after a Gastric Sleeve, was assessed in a retrospective study. Data was collected on the long-term nutritional status of 1793 Gastric Sleeve patients over a 5-year follow-up period.

Nutritional screening for deficiencies and hypervitaminosis

Prior to surgery, deficiencies were observed for vitamin D, vitamin B12, iron and ferritin, and these deficiencies still prevailed 5 years after surgery, accompanied by deteriorated anemia. In contrast, excess levels of vitamin B1, B2 and B6 were observed 1 year after operation. These gradually declined to normal levels, with only vitamin B6 still being in excess after 5 years.

After 5 years % deficient % excess
Iron 40 5
Ferritin 50 5
Vitamin D 38
Vitamin B1 3
Vitamin B6 23
Vitamin B12 15 8

Tailored supplementation is required

The data shown in this study demonstrate that levels of multivitamins and minerals are continuously changing in the years after a Gastric Sleeve. This emphasizes the need for a regular nutritional screening and subsequent adequate supplementation, not only for the short term, but also for the longer term after surgery.
