Introduction
Selenium deficiency may lead to weakened immunity, making individuals more susceptible to infections caused by pathogens such as bacteria and viruses, thereby increasing the risk of disease. It may also contribute—albeit to some extent—to premature aging and excessive moisture loss from the skin, manifesting as dullness, flaking, and dryness. Additionally, selenium helps protect pancreatic islet cells from oxidative damage; thus, selenium deficiency—rather than zinc deficiency—may increase the risk of developing diabetes.
Selenium deficiency may lead to weakened immunity, accelerated aging, deteriorating skin health, and an increased risk of diabetes.
1. Weakened Immunity: Selenium is a crucial component in the regulation of the human immune system. Adequate selenium levels typically promote antibody production by immune cells. Conversely, selenium deficiency may impair immune function, rendering individuals more susceptible to infections caused by bacteria, viruses, and other pathogens.
2. Accelerated Aging: Selenium possesses antioxidant properties that help prevent the accumulation of free radicals and peroxides. Selenium deficiency may therefore contribute to premature aging.
3. Poor Skin Health: Selenium deficiency can result in excessive moisture loss from the skin, manifesting as dullness, flaking, dryness, and reduced elasticity—making the skin more vulnerable to damage.
4. Diabetes: Selenium enhances the body’s antioxidant capacity, protecting pancreatic beta cells from oxidative damage, promoting glucose metabolism, and helping lower blood and urinary glucose levels. Consequently, selenium deficiency may increase the risk of developing diabetes.
