In recent years, there has been significant interest in the role of adipose tissue in determining the bioavailability of vitamin D, which is attributable to the well-known inverse correlation between obesity and serum 25-hydroxyvitamin D concentrations, described for all age groups, nationalities, places of residence, and independent of gender. Screening studies show that obesity is inferior to low sun exposure as a predictor of vitamin D deficiency severity, while the prevalence of obesity has already reached global pandemic proportions and is observed in about 39% of the world’s adult population. Obesity has been shown to be associated with increased mortality due to its association with comorbidities, including type 2 diabetes mellitus (DM2), arterial hypertension, dyslipidemia, osteoarthritis, and sleep apnea. At the same time, both at the physiological and biochemical levels, the active form of vitamin D has been shown to have many effects that counteract the adverse effects of obesity, which may reduce the risks of tissue damage in obesity and associated metabolic disorders, such as DM2 and cardiovascular diseases. Treatment of obesity, including bariatric surgery, does not always lead to favorable changes in the status and action of vitamin D, which must be taken into account in clinical practice.
