(CNN)People with diabetes who had trouble falling or staying asleep were 87% more likely to die of any cause over the next nine years than people without diabetes or sleep problems, a new study finds.
Poor sleep linked to weight gain in 2-year smartphone sleep tracking studyKnutson and her team also compared people with diabetes who slept well to people with the condition who often experience poor sleep.”People with diabetes who slept badly were 12% more likely to die over a nine-year followup period than people with diabetes who slept without frequent sleep disturbances,” Knutson said.The study is the first to look at the combination of diabetes plus sleep disturbances and mortality risk, she added.
Known link between diabetes and sleep problems
A study of this type can only show association and not causation, said sleep specialist Dr. Raj Dasgupta, an assistant professor of clinical medicine at the Keck School of Medicine at the University of Southern California, who was not involved in the research.Enter your email to subscribe to the Results Are In Newsletter with Dr. Sanjay Gupta.“close dialog”

Get better sleep by cuddling up with your partner“People with Type 2 diabetes are also predisposed to kidney issues and make multiple trips to the bathroom in the night because they’re always urinating, especially if their diabetes is poorly controlled,” he added. “They can also have damage to blood vessels which causes leg pain called neuropathy, and It’s hard to go to sleep because of that pain.”It’s also possible that poor quality sleep may impact the body’s ability to regulate blood sugars, thus contributing to the development of diabetes, Knutson said.”There’s experimental work which shows that if you take healthy people and disturb their sleep you see impairments in insulin sensitivity,” she said. “There could be a bidirectional association between the two, so if you have sleep issues for a long period of time it may actually lead to the development of diabetes.”
What to do?
Acknowledge and tackle your sleep problems, regardless of whether or not you have diabetes, Knutson said. Sleeping poorly is a risk factor for premature death from any cause all by itself.
