Serum Ferritin in Metabolic Syndrome-Mechanisms and Clinical Applications.

Metabolic syndrome (MS) is a cluster of conditions including central obesity, hypertriglyceridemia, low HDL cholesterol, hyperglycaemia, and hypertension with a prevalence rate of 20−25% of the world’s adult population. Metabolic syndrome is often characterized by insulin resistance, which some have suggested is a major supportive connection between physical inactivity and MS. Various studies suggest that moderately elevated iron and ferritin levels are associated with an increased prevalence of metabolic syndrome and are markers of insulin resistance.

Obesity as an Important Marker of the COVID-19 Pandemic.

In December 2019, the emergence of the new coronavirus disease 2019 (COVID-19) began in Wuhan, China. Thereafter, the disease has been spreading rapidly across the world, with about 300 million registered cases worldwide, and the numbers are also exponentially increasing in India, with about 34 million registered cases by the end of 2021. Among the comorbidities, obesity may increase the risk of hospitalization due to COVID-19 infection as it is related to immune system dysfunction.
