Prediabetes-related health problems and nonalcoholic fatty liver disease (NAFLD) frequently exist together. Obesity, poor dietary habits, and a sedentary lifestyle are similar risk factors for both conditions. When blood glucose levels are greater than the normal value but not yet at the diabetes level, are referred to as prediabetes. NAFLD is the accumulation of excess fat in the liver where alcohol consumption is not the cause. Both conditions do not cause symptoms in the early stages but can ultimately lead to serious health issues such as type 2 diabetes, damage to the liver, and heart disease. The goal of this article is to explain how these two conditions are related, why it is important to identify both conditions early, and how lifestyle modifications can reverse these conditions or prevent serious health problems down the road.
How are prediabetes and NAFLD related?
Prediabetes and nonalcoholic fatty liver disease (NAFLD) are both closely associated with insulin resistance; when the body cannot use insulin effectively, blood glucose levels increase, and the liver begins to store excess fat, resulting in nonalcoholic fatty liver disease. Many people with prediabetes do not know they have NAFLD, but research shows these two conditions often occur together. Studies say more than 70% of people with type 2 diabetes or prediabetes may also have NAFLD.
Nonalcoholic fatty liver disease and prediabetes can both develop quietly without clear symptoms. Untreated, NAFLD can lead to liver inflammation or even cirrhosis, while prediabetes can develop into diabetes. A healthy lifestyle, which includes a balanced diet, exercise, and weight management, can help prevent both conditions. Doctors may ask for diagnostic tests for NAFLD in people with prediabetes to prevent long-term damage.
Does everyone with prediabetes develop NAFLD?
Not everyone with prediabetes develops NAFLD, but the risk is much higher. NAFLD, or nonalcoholic fatty liver disease, often appears in people with high blood sugar levels. When insulin is not functioning properly, sugar accumulates in the blood, and the liver begins storing excess fat. Because it has to do with the unexpected use of insulin resistance, prediabetes and NAFLD are often connected. However, there are other factors like genetics, lifestyle, and body weight which can also contribute a lot.
Some people with prediabetes will never develop NAFLD because they eat healthy and exercise. Others will develop fatty liver, especially if they have obesity or insulin resistance. While some people do not have symptoms of NAFLD, if left untreated, it can result in liver damage.
Healthcare providers suggest that people with prediabetes have regular check-ups with blood work to screen for NAFLD disease early. There is overlap between NAFLD and prediabetes; both can be modified with diet, exercise, and weight loss. The sooner one can address their prediabetes or NAFLD, the lower the risk the individual will be for other health problems.
What’s the long-term risk if you ignore prediabetes and NAFLD?
Ignoring prediabetes and fatty liver can lead to serious long-term health problems. If left untreated, prediabetes often turns into type 2 diabetes, which can damage the kidneys, eyes, and nerves. At the same time, fatty liver, also known as nonalcoholic fatty liver disease (NAFLD), can get worse. It may progress to liver inflammation, scarring (fibrosis), or even cirrhosis, which is permanent liver damage.
Prediabetes and fatty liver often develop without telling signs or symptoms. Many people aren’t aware they have either one until it becomes a big issue for their health. Some studies suggest that approximately 70% of people with diabetes mellitus have NAFLD. Prediabetes and NAFLD can together increase the risk of cardiac complications and liver failure.
Making simple changes—like eating healthy, exercising, and losing weight—can reverse early damage. For those who are at risk, early screening is advised by doctors. Managing prediabetes and fatty liver early helps prevent serious complications and improves long-term health.
Can you reverse NAFLD if you have prediabetes?
Yes. You can usually reverse NAFLD if you’re prediabetic, especially if both conditions are identified early. Excess fat is accumulated in the liver, which causes NAFLD (nonalcoholic fatty liver disease). If you’re prediabetic, your blood sugar is higher than normal, but you don’t have diabetes. These two issues are sometimes associated with insulin resistance as well as unhealthy lifestyle behaviours like poor nutrition, exercise avoidance, and weight gain.
Most people are able to reduce fatty liver and continue to lower blood sugar by simply making healthy lifestyle changes. The suggestion is to lose 5–10% of your body weight through a healthy combination of a well-balanced diet and daily exercise. Reducing weight will help the liver optimally function and insulin to be used better in the body. Additionally, liver health will be improved by reducing alcohol, fat, and sugar.
Most individuals with prediabetes or NAFLD do not have alarming symptoms, which is why health checks are important. If you act quickly, you can reverse any permanent damage to your body and likely prevent longer-term issues such as diabetes, inflammation of the liver, or capabilities for heart disease. Prevention is key.
