June 13th marks Global Fatty Liver Day, a global public education campaign dedicated to raising awareness about nonalcoholic fatty liver disease (NAFLD) and its more advanced form, nonalcoholic steatohepatitis (NASH).
These conditions represent a hidden epidemic, with an estimated 155 million people worldwide affected by NASH – and that number is projected to more than double by the year 2030. Organized by the Global Liver Institute, Global Fatty Liver Day, also known as NASH Day, serves as a crucial reminder of the importance of liver health screenings and awareness about these silent but potentially dangerous conditions.
Global Fatty Liver Day is an annual event that brings together healthcare professionals, patients, and advocates to share knowledge, resources, and support about NASH and NAFLD. Through various activities, including educational webinars, health screenings, and social media campaigns, Global Fatty Liver Day seeks to inform the public about the risks and consequences of fatty liver disease, as well as the importance of early detection and lifestyle changes in managing and preventing these conditions.
What Is NAFLD and NASH?
Nonalcoholic fatty liver disease, or NAFLD, is a common liver condition characterized by the accumulation of excess fat in the liver of people who consume little to no alcohol. NAFLD can progress to a more severe form of the condition known as nonalcoholic steatohepatitis, or NASH. When the condition progresses to NASH, inflammation and liver cell damage occur, causing the liver to swell. NASH poses a significant health risk due to its potential to cause serious liver complications. It may potentially lead to liver fibrosis and liver scarring, called cirrhosis, and even liver cancer. While both NAFLD and NASH are often asymptomatic in the early stages, their progression can lead to significant liver damage if left untreated.
Nonalcoholic Fatty Liver Disease: Are You at Risk?
Certain factors increase the risk of developing NAFLD and NASH. These include obesity, type 2 diabetes, metabolic syndrome, high cholesterol, hypertension, high triglycerides, hypothyroidism, sleep apnea, and polycystic ovary syndrome. Lifestyle factors such as poor diet and lack of physical activity may also contribute to the development of these conditions, and those who smoke or are over the age of 50 are also at an increased risk.
Understanding the risk factors is crucial for early intervention. Regular check-ups and liver health screenings are recommended for those at higher risk of developing the disease to detect and treat the disease early.
Symptoms and Causes of Nonalcoholic Fatty Liver Disease
NAFLD and NASH are often referred to as “silent” diseases because they can develop with little or no noticeable signs or symptoms. Fatigue and pain in the upper right abdomen (often mild) are the most common symptoms, along with an enlarged liver.
The primary cause of NAFLD is the accumulation of fat in the liver. When this fat build up leads to inflammation and liver cell damage, the condition progresses to NASH. While the cause is unknown, contributing factors include genetic predisposition, hormonal imbalances, and certain medications.
Nonalcoholic Fatty Liver Disease Diagnosis
Diagnosing NAFLD and NASH typically starts with a combination of medical history review, physical examination, and diagnostic tests. If NAFLD is suspected, a blood test is given to check liver enzymes, called a liver function test. Blood tests may not always show NAFLD. Imaging studies such as ultrasound or magnetic resonance imaging (MRI) may help with diagnosis. If NAFLD is diagnosed, further tests may be needed to determine the extent of liver fat and damage. This may involve another type of ultrasound scan called a Fibroscan, a special blood test, or a liver biopsy.
Early diagnosis is key for effective management of NAFLD and NASH. Regular monitoring and liver health screenings can help detect changes in your liver health and guide treatment plans to help slow or prevent disease progression.
When to Talk to Your Doctor
If you have risk factors for NAFLD or NASH, or if you experience symptoms such as persistent fatigue or abdominal discomfort, especially in the upper right abdomen, now is the time to consult with your healthcare provider. A healthcare provider can assess your risks, symptoms, and medical history to determine if diagnostic tests should be performed, and to make a plan for regular monitoring. Early detection and intervention can significantly improve outcomes and reduce the risk of severe liver damage.
Whether you are diagnosed with NASH or not, your doctor can provide guidance on lifestyle changes to help prevent NAFLD or stop the progression to NASH. These may include adopting a healthy diet, increasing physical activity, quitting smoking, and managing underlying conditions like diabetes and hypertension. In some cases, medication may be prescribed to manage specific aspects of the disease.
Global Fatty Liver Day on June 13th is a day to raise awareness about NAFLD and NASH, highlighting the importance of liver health screenings and early intervention. By understanding the risk factors, symptoms, and diagnostic methods, individuals can take proactive steps to protect their liver health. Through education and awareness, we can work together to reduce the burden of fatty liver disease and promote better liver health globally.
