Prevalence, Sonographic Grading and Factors Associated with Metabolic Dysfunction-Associated Steatotic Liver Disease among Adults with Type 2 Diabetes Mellitus: A Multicenter Cross-Sectional Study in Uganda
This multicenter cross-sectional study in Uganda reveals a 54.5% prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) among adults with type 2 diabetes, identifying age, hypertension, obesity, poor glycemic control, and elevated triglycerides as key independent risk factors.

In many parts of the world, a quiet shift is happening inside the bodies of people with type 2 diabetes. For years, doctors have focused on blood sugar, but they are increasingly aware that the liver is often struggling alongside the pancreas. When the liver becomes filled with excess fat, not because of heavy drinking but because of how the body processes sugar and energy, it enters a state now called metabolic dysfunction-associated steatotic liver disease. This condition is not merely a storage issue; it can silently progress to scarring, inflammation, and serious liver failure. The connection is strong: the same factors that make blood sugar hard to control—such as excess weight, high blood pressure, and abnormal fat levels in the blood—also drive fat into the liver. Because this disease often shows no symptoms until it is advanced, finding it early is a major challenge, especially in regions where advanced medical imaging is scarce.
A team of researchers in Uganda decided to look closely at this hidden burden. They traveled to two regional hospitals, one in the central-east and one in the west, to examine the livers of adults living with type 2 diabetes. Their goal was simple but vital: to see how common this fatty liver condition was, how severe it had become, and which specific health factors made it more likely to appear. They worked with 422 adults who were already receiving care for their diabetes. To ensure their findings were accurate, they carefully excluded anyone with a history of heavy alcohol use, viral hepatitis, or other known liver diseases, focusing strictly on the metabolic link. The team used abdominal ultrasound, a safe and accessible imaging technique that uses sound waves to create pictures of the inside of the body, to detect and grade the amount of fat in the liver. They also measured blood sugar control, blood pressure, body weight, and levels of fats circulating in the blood.
The results revealed a significant health concern. More than half of the adults with diabetes in this study, specifically 54.5 percent, were found to have fatty liver disease. This means that for every two people with diabetes in these clinics, one likely had fat accumulating in their liver without knowing it. When the researchers looked at the severity of the condition, they found that most cases were mild. About three-quarters of those with the disease had only a small amount of fat, which showed up as a slight brightening on the ultrasound images. A smaller group had a moderate amount, and very few had severe fat accumulation. This pattern suggests that while the condition is widespread, it is often caught at an early stage where it might still be reversible with lifestyle changes.
The study also pinpointed exactly who was most at risk. The likelihood of having fatty liver disease increased steadily with age. Adults in their late forties and fifties, and especially those over sixty, were significantly more likely to have the condition than younger adults. Beyond age, five other factors stood out as powerful predictors. People with high blood pressure were nearly twice as likely to have fatty liver. Those with a body mass index of thirty or higher, which indicates obesity, faced a similar increase in risk. The state of their diabetes control mattered deeply; patients whose blood sugar levels were not well managed were more than twice as likely to have the condition. Finally, high levels of triglycerides, a specific type of fat found in the blood, were strongly linked to the disease. When these factors were present together, the risk grew even higher.
These findings offer a clear path forward for doctors and patients in Uganda and similar settings. The study confirms that fatty liver disease is a common companion to type 2 diabetes in this region, affecting a substantial portion of patients. It also demonstrates that a simple ultrasound scan can effectively identify the problem early, before serious damage occurs. The researchers suggest that checking the liver should become a standard part of diabetes care, particularly for older patients or those with high blood pressure, obesity, or poor blood sugar control. By identifying these cases early, medical teams can work with patients to manage their weight, diet, and medications, potentially stopping the disease before it progresses to more dangerous stages. The study does not claim to have solved the problem, but it provides a reliable map of where the problem exists and who needs help most urgently.
