Vitamin D deficiency may be related to the development of the metabolic syndrome for the menopausal woman.
The metabolic syndrome (or syndrome X) is a deregulation of the metabolism of macronutrients (carbohydrates and lipids in particular) that can lead to serious complications such as the development of type 2 diabetes or increased risk of heart disease and accidents cerebrovascular diseases. A metabolic syndrome is diagnosed when at least three of the following factors are present: abdominal overweight, high blood pressure, high blood sugar, high triglyceride levels, high cholesterol. This syndrome is more prevalent for people over 50 years old.
A study published in January 2018 by researchers at the University of Sao Paulo (Brazil) suggests that postmenopausal women with vitamin D deficiency are more likely to develop a metabolic syndrome than others. Thus, maintaining an adequate level of vitamin D in postmenopausal women would reduce the risk of metabolic syndrome.
The study was conducted on 463 women aged 45 to 75 who did not take vitamin D supplements and had cardiovascular disease. Only a third of these women had sufficient vitamin D levels. 57% of women who did not have adequate vitamin D levels had metabolic syndrome, compared to 39% of women with adequate levels of vitamin D.
The lack of vitamin D
Some physiopathological mechanisms may explain the effect of a lack of vitamin D on the metabolic syndrome: vitamin D influences the secretion of insulin.
This lack of vitamin D can be caused by various factors: the reduction of outdoor sports activities and therefore a decrease in sun exposure or a decrease in the ability of the skin to synthesize vitamin D (caused by age )
