Weight and Your Liver Health- with Emily Sutton, PharmD
When it comes to health, we often hear about the importance of maintaining a healthy weight. However, what many people might not realize is that excess weight can have serious consequences on our internal organs, particularly the liver. In recent years, nonalcoholic fatty liver disease (NAFLD) has been on the rise, becoming a significant concern in the medical community. In fact, NAFLD has quickly become the leading cause of liver disease worldwide, surpassing even hepatitis and alcohol abuse. To shed light on this important topic, we've brought in an expert, Emily Sutton, a clinical pharmacist specializing in chronic diseases, diabetes, and obesity. In this episode, we'll delve into the details of metabolic liver disease, its impact, and how you can take steps to maintain liver health.
Meet Emily Sutton
Emily Sutton is a clinical pharmacist with expertise in chronic diseases, diabetes management, and obesity. She holds a Doctorate of Pharmacy degree from the University of Iowa and completed her residency at the University of Mississippi. Based in Vermont, Emily is committed to providing equitable care and access to appropriate medications for patients from diverse backgrounds.
The Hidden Impact of Excess Weight on the Liver
Emily's journey into exploring liver health began during her pharmacy studies, where she noticed a surprising number of patients with liver issues, despite not displaying the typical signs associated with liver disease. This prompted her to dig deeper and attend a lecture by a liver specialist, where she learned about nonalcoholic fatty liver disease (NAFLD). NAFLD is a condition where excess fat accumulates in the liver, leading to inflammation and potential scarring. This condition often goes unnoticed until it progresses to more severe stages.
Emily's experience in Vermont, particularly with patients from Asian countries, highlighted the diversity of individuals affected by NAFLD. Even those with lower BMIs were at risk due to varying fat metabolism. This realization sparked her interest in understanding the relationship between obesity, metabolic syndrome, and liver health.
The Complex Connection: Obesity, Metabolic Syndrome, and Liver Health
Obesity and metabolic syndrome play significant roles in the development of NAFLD. Metabolic syndrome refers to a cluster of conditions, including high blood pressure, high blood sugar, excess abdominal fat, and abnormal cholesterol levels. These factors can contribute to insulin resistance and chronic inflammation, which increase the risk of liver damage.
Emily emphasizes that the amount of weight isn't the sole determining factor for liver health. Genetics, body composition, and overall metabolic health play a vital role. Some individuals with only a small amount of excess weight can experience liver issues due to their body's tolerance to fat accumulation.
NAFLD and Its Progression
NAFLD progresses over time, and its severity can range from simple fatty liver (steatosis) to nonalcoholic steatohepatitis (NASH), which involves inflammation and scarring of the liver. In severe cases, NASH can lead to cirrhosis and even liver cancer. However, it's important to note that not everyone with NAFLD will progress to these advanced stages. Much of the focus should be on identifying the early signs of liver dysfunction and implementing appropriate interventions
The Power of Weight Loss
Emily emphasizes that weight loss is a crucial intervention for individuals with NAFLD. Research has shown that a weight loss of 5% to 10% can significantly improve liver health, and a weight loss of 15% or more can even reverse the condition in some cases. The focus should be on sustainable weight loss that an individual can maintain over the long term.
Lifestyle Changes and Medications
While there are currently no medications specifically approved for treating NAFLD, lifestyle changes play a significant role in managing the condition. Weight loss, a healthy diet, and exercise are essential components. Emily points out that some newer medications used for diabetes management, like GLP-1 receptor agonists, have shown promise in improving liver health due to their anti-inflammatory effects.
Early Detection and Monitoring
Emily emphasizes the importance of early detection and monitoring for NAFLD. Regular blood tests that include liver enzymes, such as AST, ALT, and ALP, can provide valuable insights. Elevated levels of these enzymes might indicate liver dysfunction. Additionally, a simple calculation called the Fib-4 index can estimate the degree of liver scarring. Early detection allows for interventions to prevent or slow down disease progression.
Understanding the connection between obesity, metabolic syndrome, and liver health is crucial for preventing and managing NAFLD. While NAFLD has become a leading cause of liver disease worldwide, there's hope in the power of lifestyle changes, particularly weight loss. Emily Sutton's insights shed light on the importance of early detection, regular monitoring, and making sustainable choices for overall health. With the right knowledge and actions, individuals can take control of their liver health and reduce their risk of NAFLD-related complications.
