Type 2 Diabetes and Sleep Disturbances
Diabetes is a fast increasing lifestyle metabolic disorder. Adequate sleep is important for proper functioning of the body. The rampant deprivation of sleep can lead to a slew of health ailments.
Human sleep occurs in the form of circadian cycle. A circadian rhythm implies to a 24-hours physiological cycle that determines the sleep and waking pattern of living beings.
Diabetes type 2 affects the normal sleep-wake cycle however not much is known about the exact mechanism causing it.
Tomoko Nakanishi et al conducted a study to analyze the bedtime, waking time and average estimated sleep in non-type 2 diabetic and type 2 diabetic individuals. The study was published in the journal of Diabetology and Metabolic Syndrome 2012.
106 respondents were categorized in two groups: non-type 2 diabetics (32) and type 2 diabetics (74). Questionnaire comprising of various questions on sleep status and lifestyle related diseases was given to them and results were analyzed.
It was discovered that on weekdays the type 2 diabetic respondents went to bed later than the non-type2 diabetics. Type 2 diabetic patients also woke up relatively later than the non-diabetics on weekdays and holidays. However no considerable differences were noticed in the sleep duration in the two groups of respondents. Type 2 diabetics were reported to sleep more than the non-diabetics in daytime.
The study concluded that the irregularities of sleep-wake cycle are common in type 2 diabetic individuals in contrast to non- type 2 diabetics. Further research is required to confirm the role of such sleep abnormalities in type2 diabetes mellitus patients.
