World Liver Day: Fatty Liver Disease and Obesity
Liver Disease occurring from excess fat accumulation is called Fatty Liver Disease or Non-Alcoholic Steato-Hepatitis (NASH). This arises from the excess fat deposition in liver cells in people who take little or no alcohol. Hence the fat accumulation is purely from diet and Obesity. This is currently the most common liver disease in the world affecting almost 80-100 million people.
World Liver Day:
The excess fat affects the function of the liver which gradually deteriorates. This is also considered one of the factors of Metabolic Syndrome. In its most severe form, this can lead to permanent liver damage i.e. Cirrhosis i.e. scarring of the liver. This causes liver failure requiring the liver transplant. NASH may progress to cirrhosis in ~20% of patients, and NASH-related cirrhosis is considered a major cause of cryptogenic cirrhosis and liver-related death.
Fatty liver contributes to Insulin resistance and type 2 Diabetes. Bariatric Surgery helps in gradual, stable and long-term weight loss. Many patients with early changes of cirrhosis have shown significant improvement in liver inflammation after Bariatric Surgery. Weight loss after Bariatric surgery helps remove fat accumulated in the liver, thus improving their function. It has also shown to stabilize or reverse the changes of liver damage due to NASH. Many national and international studies have proven with liver biopsy, the improvement in liver changes after Bariatric Surgery. Bariatric Surgery can help stabilize or reverse fatty liver changes, thus protecting severely obese patients from going into liver failure.
World Liver Day:
It is observed on every 19 April, to spread awareness about the liver-related disease. The liver is the second largest and the most complex organ in the body, with the exception of the brain.
