Vitamin D – substitution after malabsorption operations

Petr Hlavatý1, Petra Šrámková1

+ Affiliation


Vitamin D is a biologically active substance with a significant impact on human health. More than 100 years ago, fish oil, containing high concentrations of vitamin D, was administered to infants and young children as an effective means of preventing rickets. Later, vitamin D treatment was shown to prevent softening of bone, even in adults. In additon to its association with bone health, vitamin D has been shown to have neuromuscular, immunomodulatory, and cardiovascular activities, as well as antiproliferative and anti-angiogenic effects. Vitamin D deficiency is common, especially in the elderly, as well as being one of the most common deficiencies in patients after bariatric surgery. Therefore, it is necessary to monitor vitamin D levels in these patients pre-operatively and at regular postopertive intervals. Patients undergoing malabsorption surgery must take lifelong vitamin D supplements.
