Comparison of Mg Vs. K Supplementation on Insomnia in Diabetics

Overview

Insomnia is increasing alarmingly among the population. Micronutrient fluctuations have been shown to effect insulin secretion, period of circadian cycle and quality of sleep in all ages. This study is aimed to identify the impact of magnesium and potassium supplementation on insomnia severity and duration, and insulin resistance, quality of life, sleep hormones, serum magnesium and potassium levels. Moreover, the study will help to find out the link between insomnia and micronutrients among patients of diabetes mellitus so that the burden of the disease in the society could be reduced.

Sleep is the essential component to maintain good health of an individual. Insomnia is defined as a condition that affects an individual by inability to get sufficient quality sleep or problem in maintaining sleep that is important for healthy functioning, performance and well being. Insomnia can exist in healthy individual or comorbidly with other medical diseases. Latest researches indicate that intolerance of glucose in the body, resistance to insulin hormone, decreased acute response of insulin to glucose and increased chances of having type 2 diabetes are reasons for reduced or interrupted sleep. Several electrolytes and minerals influence the sleep cycle. Magnesium is important in regulation of central nervous system excitability, through ion channel conductivity. Magnesium is a muscle relaxant and inducer of the deeper sleep. Hypomagnesemia is a common feature in patients with type 2 diabetes. Although diabetes can induce hypomagnesemia, magnesium deficiency has also been proposed as a risk factor for type 2 diabetes. Magnesium supplementation improves sleep efficiency, sleep time and sleep onset latency, early morning awakening, and insomnia objective measures such as the concentration of serum renin, melatonin, and serum cortisol, in older adults. High ambient potassium levels have been shown to shorten the period of circadian rhythms in a variety of organisms. Little is known about the effects of dietary mineral nutrients on human sleep quality. Potassium depletion has been shown to cause glucose intolerance, which is associated with impaired insulin secretion . Recently, there has been growing evidence from both animal and human studies indicating that high sodium and low potassium intakes are associated with a high risk of insulin resistance or diabetes. The Study is aimed to: 1. To compare the effect of magnesium and/ or potassium on insomnia patients with diabetes mellitus 2. To compare the gender and age based response to magnesium and/ or potassium on insomnia patients with diabetes mellitus 3. To compare the effect of magnesium and/ or potassium on insulin resistance among insomnia patients with diabetes mellitus 4. To compare the effect of magnesium and/ or potassium on sleep hormones among insomnia patients with diabetes mellitus 5. To compare the effect of magnesium and/ or potassium on serum electrolytes (Mg, K) among insomnia patients with diabetes mellitus 6. To compare the effect of magnesium and/ or potassium on quality of life (QOL) among insomnia patients with diabetes mellitus MATERIAL AND METHODS Study Design: Randomized Controlled Trial (single blind) Settings: Study will be conducted at 1\. Akhuwat Health Services, Lahore Duration of Study: 18 months (after the approval of synopsis) Sample Size: is 280 and with expected 20% drop out: 320 Sampling Technique: Non probability purposive sampling Inclusion Criteria: * Patients of diabetes mellitus with insomnia * Adult diabetic patients aged between 19 to 65 years * Patients of both genders * Diabetic patients of insomnia with or without antidiabetic drugs
