Fatty liver linked to increased risk of death from several diseases: Study

The researchers identified all patients diagnosed with MASLD in Sweden between 2002 and 2020, more than 13,000 patients in total, and analysed their risk of death from different causes compared to the general population.

The overall mortality rate for people with MASLD was almost twice as high. The risk was elevated for nearly all causes of death studied, but especially for death from liver disease (27 times higher mortality) and liver cancer (35 times higher mortality). However, the most common causes of death were cardiovascular disease and non-liver cancer, with mortality rates 54 and 47 per cent higher, respectively.

A holistic approach

People with MASLD also had an increased risk of dying from infections, gastrointestinal diseases, respiratory diseases, endocrine diseases or external causes, but not from mental illness.

“It is important that we do not only focus on the liver when treating patients with fatty liver disease,” says Hannes Hagström, adjunct professor at the Department of Medicine, Huddinge, Karolinska Institutet and senior physician at Karolinska University Hospital. “A holistic approach and early intervention involving different medical specialities can be crucial to improve the prognosis for these patients.”
