Treatment of Malabsorption in Vitamin B12 Deficiency Due to Food-Bound Cobalamin Malabsorption

Clinical Scenario

This protocol applies to patients presenting with malabsorption in the context of vitamin B12 deficiency caused by food-bound cobalamin malabsorption — a condition in which cobalamin bound to food proteins cannot be adequately released and absorbed in the gastrointestinal tract.

Comorbidity in Focus

The defining feature of this scenario is vitamin B12 deficiency anemia arising from impaired absorption of food-bound cobalamin. Micronutrient deficiencies in malabsorptive syndromes require systematic screening and appropriate correction.

Treatment Approach (partial)

Management centres on lifelong cobalamin supplementation. The structured protocol specifies the route, dose, and schedule — details of the complete regimen are available via the full protocol below.

Treatment Goal

Correction of vitamin B12 deficiency with normalisation of vitamin B12 levels.

References

Patients with food-bound cobalamin malabsorption should receive lifelong supplementation either as a daily dose of 350 μg of cobalamin orally or as intramuscular injections of 1000-2000 mcg of cobalamin every 1-3 months.

In malabsorptive syndromes, micronutrient deficiencies should be screened, and any deficiency should be properly corrected.
