People with diabetic peripheral neuropathy experience sleep disturbances more frequently than those without, particularly when neuropathic pain is present, and gabapentinoid medications reduce sleep interference scores by an average of 1.07 points.
- Sleep problems are more common in people with diabetic nerve damage, especially those with pain
- Poor sleep quality in diabetes may itself increase the risk of developing neuropathy
- Gabapentinoid medications appear to improve sleep interference scores in painful diabetic neuropathy
How this compares to prior research
While both diabetic neuropathy and reduced sleep quality are recognized as frequent complications of diabetes mellitus, their interaction and mutual influence have remained poorly understood. Previous research had not clearly established whether sleep disturbances were more common in people with diabetic neuropathy or whether poor sleep might contribute to neuropathy development. This review synthesized evidence from 32 studies to clarify these relationships.
Diabetes prevalence trends, global population, 1990–1999
Key findings
- Sleep disturbances were more prevalent in people with diabetic peripheral neuropathy compared to people without, especially in those experiencing neuropathic pain
- Obstructive sleep apnea was common in individuals with autonomic neuropathy
- Gabapentinoids reduced Sleep Interference Scores by a pooled mean difference of -1.07 points (95% CI: -1.86 to -0.28) in people with painful diabetic peripheral neuropathy
What this means in practice
- Ask your doctor about sleep quality if you have diabetic neuropathy, as addressing sleep problems may improve overall health outcomes
- Consider discussing gabapentinoid medications with your healthcare provider if neuropathic pain is disrupting your sleep
- If you have diabetes and poor sleep, note that improving sleep quality may help reduce your risk of developing nerve damage
Frequently asked questions
Does diabetic nerve damage affect sleep quality?
Yes, people with diabetic peripheral neuropathy experience sleep disturbances more frequently than those without the condition, particularly when neuropathic pain is present.
Can poor sleep increase the risk of diabetic neuropathy?
Evidence suggests that poor sleep quality in people with diabetes may itself increase the risk of developing diabetic neuropathy, indicating a bidirectional relationship.
Do gabapentinoid medications help with sleep in diabetic neuropathy?
Yes, gabapentinoids appear to reduce sleep interference scores in people with painful diabetic peripheral neuropathy by an average of 1.07 points.
Key terms explained
