Одним из осложнений в послеоперационном периоде является снижение минеральной плотности костной ткани, что приводит к повышенному риску переломов. Существует множество различных механизмов нарушения минерального обмена после бариатрических операций, однако ключевую роль играет снижение всасывания кальция и витамина D. Известно, что витамин D участвует во всех основных процессах, протекающих в костной ткани. Он является наиболее важным эндокринным регулятором кальциевого гомеостаза в организме, обеспечивая всасывание 90% кальция в кишечнике. У пациентов с морбидным ожирением имеется высокий риск дефицита витамина D еще до проведения операции, который может усугубиться после оперативного вмешательства и при отсутствии своевременного лечения привести к тяжелым нарушениям фосфорно-кальциевого обмена. Обнаружено, что высокие дозы витамина D после бариатрических операций могут способствовать улучшению состояния костного метаболизма и, как следствие, предотвращению развития тяжелых переломов после операции, что в целом благотворно влияет на качество жизни и трудовой прогноз. Результаты имеющихся на сегодняшний день исследований открывают новые возможности для профилактики и лечения послеоперационных осложнений, связанных с нарушением костного обмена.</p></abstract><trans-abstract xml:lang="en"><p>This article provides a review of current literature on the effect of various doses of vitamin D on the parameters of calcium and phosphorus metabolism in patients after bariatric surgery.</p><p>The decrease of bone mineral density is one of the most frequent complications of the bariatric surgery, which increases the risk of fractures. There are many different mechanisms for impaired mineral metabolism after bariatric surgery, but a decrease in the absorption of calcium and vitamin D plays a key role in this process. Vitamin D is the most important endocrine regulator of calcium homeostasis in the body, which provides the absorption of 90% of calcium in the gut. Patients with morbid obesity have a high risk of vitamin D deficiency even before surgery, which may worsen after operation and in the absence of timely treatment lead to severe disturbances of calcium and phosphorus metabolism.</p><p>It was found that high doses of vitamin D after bariatric surgery can improve parameters of bone metabolism, and, as a result, prevent fractures after surgery, which generally has a beneficial effect on the quality of life and labor prognosis. The results of the studies available to date open up new opportunities for the prevention and treatment of postoperative complications associated with impaired bone metabolism.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>витамин D</kwd><kwd>ожирение</kwd><kwd>кальций</kwd><kwd>бариатрическая операция</kwd><kwd>гастрошунтирование</kwd><kwd>остеопороз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>vitamin D</kwd><kwd>obesity</kwd><kwd>calcium</kwd><kwd>bariatric surgery</kwd><kwd>Roux-en-Y</kwd><kwd>osteoporosis</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Who.int [Internet].
