Waking Up at Night Could Be a Sign of Fatty Liver Disease—And Stress May Be Involved, Study Finds

Key Takeaways:

  • MASLD patients wake more frequently and stay awake longer at night
  • Poor sleep may signal or worsen liver dysfunction
  • More research is needed on sleep-focused MASLD treatment

Restless nights and frequent awakenings may indicate metabolic-associated fatty liver disease (MASLD), a condition that often progresses silently. This finding comes from a study conducted by researchers at the University of Basel, recently published in the journal Frontiers in Network Physiology.

Restless Sleep and Fatty Liver Disease: The Study

To explore the connection between sleep disruptions and MASLD, researchers studied 46 adults diagnosed with the condition. Eight patients with cirrhosis unrelated to MASLD served as a comparison group, along with a control group of 16 healthy volunteers. Participants wore activity and body temperature monitors for four weeks and maintained sleep journals, providing detailed insights into their sleep patterns.

The results revealed that while sleep duration and time in bed were similar between MASLD patients and healthy controls, those with MASLD experienced significantly more restless nights. They woke up 55% more often and remained awake 113% longer during these episodes.

Additionally, MASLD patients reported lower sleep quality, with 32% attributing their disturbances to stress, compared to just 6% of the healthy group. They also napped more frequently and for longer periods during the day.

Topic Findings
What is MASLD? A liver condition caused by fat buildup, linked to obesity, diabetes, and metabolic syndrome.
Sleep and MASLD MASLD patients wake up 55% more often and spend 113% longer awake during the night.
Daytime Impact Patients nap more frequently and report lower overall sleep quality compared to healthy adults.
Study Participants 46 with MASLD, 8 with unrelated cirrhosis, and 16 healthy controls were monitored.
Interventions Tested A single session of sleep hygiene education was insufficient to improve sleep patterns.

Sleep Fragmentation: Cause or Effect?

The study concluded that sleep fragmentation may play a role in the progression of MASLD, but the direction of causality remains unclear. “We concluded from our data that sleep fragmentation plays a role in the pathogenesis of human metabolic-associated fatty liver disease. It remains unclear whether MASLD causes sleep disturbances or vice versa,” explains Dr. Sofia Schaeffer, corresponding author of the study.

Underlying factors, such as genetics, obesity, metabolic syndrome, and immune responses, are believed to contribute to both sleep disruptions and liver disease.

Can Improving Sleep Help Manage MASLD?

The research team also examined whether improving sleep could alleviate symptoms of MASLD. A single session of sleep hygiene education did not produce lasting changes in sleep patterns for either MASLD patients or healthy individuals.

“Future studies should explore follow-up sleep counseling or interventions like light therapy combined with other lifestyle changes to improve the sleep-wake cycle in MASLD patients,” notes Dr. Christine Bernsmeier, lead author of the study.

Final Thoughts

Waking up often during the night might seem like just a sleep issue, but it could be a sign your body’s under more strain than you realize. While this study raises important questions, it doesn’t give us all the answers. The sample size was small, and it’s still unclear whether poor sleep drives liver issues, or the other way around.

What’s clear is that stress, disrupted sleep, and metabolic health are all connected. If you’re dealing with restless nights alongside other risk factors like weight gain, fatigue, or high blood sugar, it’s worth having a broader conversation with your doctor.
