And that’s why magnesium deficiency can cause various health issues. The roots of this deficiency can be different: poor diet, malabsorption issues from conditions like Crohn's disease, excessive loss due to medications like diuretics, or chronic conditions like alcoholism and diabetes. Aging and chronic stress can also contribute to reduced magnesium levels. A lack of magnesium can lead to a range of health problems. These include muscle cramps and weakness, irregular heart rhythms, elevated blood pressure, and decreased bone density, raising the risk of osteoporosis. Mental health can also be affected, leading to symptoms of depression or apathy. In severe cases, magnesium deficiency can contribute to respiratory issues, hormonal imbalances, and even insulin resistance, which can be a precursor to Type 2 diabetes.
