FEATURES OF MANIFESTATION OF NONALCOHOLIC STEATOHEPATITIS IN OBESE PATIENTS AFTER LAPAROSCOPIC SLEEVE GASTRECTOMY

The state of energy starvation is the main phenomenon of the early postoperative period of bariatric surgery. All organs and systems of the body undergo such changes. Under normal physiological conditions, with the development of energy hunger, there is an excitation of metabolic centres in the hypothalamic-pituitary system of the brain. Transmitted impulses from chemoreceptor cells increase lipolysis, which ultimately leads to the mobilisation of large amounts of fatty acids from the fat depot to the liver. Excessively high concentrations of ketone bodies due to rapid weight loss are accompanied by the development of ketonemia, the severity of which depends not only on the compensatory capabilities of the body but also on the condition of the liver. Ketonemia is one of the common side effects reported by patients after bariatric surgery. Despite this, the evidence for the incidence of ketonemia after various bariatric surgeries and the mechanism of the development of this phenomenon is very limited. In this regard, this scientific article is devoted to the features of the manifestation of ketonemic syndrome in obese patients after the most popular type of bariatric surgery - laparoscopic longitudinal resection of the stomach.
