“A decrease in sunlight pushes the body to store more cholesterol than usual as a protective measure. The seasonal variation in cholesterol levels could lead to more progression of fatty liver disease in the winter. Physical activities decrease during winters, and skipping exercise routine may be a contributor to the increase in cholesterol readings,” said Ravinder Pal Singh, Head of liver Transplant and Gastrosciences at Super Specialty Hospital.
Contending that physical exercise is the best way to keep obesity and diabetes away, which in turn helps to keep the liver damage-free, Singh said: “The association between high cholesterol and fatty liver disease becomes more apparent with the arrival of the winter months.”
“Cholesterol levels are highest during the winter months and lowest during the summer months. The reasoning behind the seasonal variability in blood cholesterol levels is unclear, especially because there is no significant difference in dietary intake,” said Singh.
Several medical statistics showed that 80 per cent of people who are obese or diabetic are more prone to liver diseases during winter and remaining 20 per cent suffer from non-alcoholic fatty liver (NAFL).
