Are there metabolic problems linked to having chronic insomnia while hospitalized?
Chronic insomnia is a common issue for people in the hospital, and it may be linked to metabolic problems. A 2025 study of hospitalized adults found that many patients with chronic insomnia also had high blood sugar (hyperglycemia) and abnormal blood lipids (dyslipidemia) 4. This suggests that sleep problems in the hospital may be connected to metabolic health, though the study does not prove that insomnia causes these issues.
What the research says
A retrospective study of 871 hospitalized adults with chronic insomnia found that a significant proportion had elevated fasting blood glucose and dyslipidemia 4. The study did not compare these patients to a control group without insomnia, so it cannot determine whether insomnia directly causes metabolic problems or if other factors (such as the reason for hospitalization) are responsible. However, the findings align with broader research linking sleep disruption to metabolic issues. For example, night shift work, which disrupts sleep, has been associated with higher total cholesterol in male miners 6. Additionally, metabolic syndrome—a cluster of conditions including dyslipidemia and high blood sugar—is linked to sleep disturbances and other health problems 10. While the hospital study 4 provides direct evidence of metabolic abnormalities in hospitalized patients with chronic insomnia, more research is needed to understand the exact relationship.
What to ask your doctor
- Could my chronic insomnia affect my blood sugar or cholesterol levels?
- Should I have my fasting blood glucose and lipid panel checked while I'm in the hospital?
- Are there treatments for insomnia that might also help my metabolic health?
- How can I improve my sleep in the hospital to potentially reduce metabolic risks?
