seleniumpoor

Seleniumpoor refers to a deficiency in the essential trace mineral selenium. Selenium plays a crucial role in various bodily functions, including antioxidant defense, thyroid hormone metabolism, and immune system support. Deficiency can occur due to low selenium content in soil and, consequently, in the food grown in that soil, or due to poor absorption from the diet.

Symptoms of selenium deficiency can vary depending on the severity and individual factors. Mild deficiency might present with subtle signs, while severe deficiency can lead to more pronounced health issues. These can include impaired immune function, making individuals more susceptible to infections. It is also linked to Keshan disease, a cardiomyopathy primarily affecting children and women in selenium-deficient regions, and Kashin-Beck disease, a type of osteoarthritis. Cognitive impairment and muscle weakness have also been observed in some cases.

Diagnosis typically involves assessing dietary intake and, in some instances, blood or urine selenium levels. Treatment involves selenium supplementation, usually through oral supplements or by increasing consumption of selenium-rich foods such as Brazil nuts, seafood, organ meats, and eggs. Preventing selenium deficiency involves ensuring adequate intake through a balanced diet or, where necessary, fortification of staple foods in affected regions. The recommended daily intake of selenium varies by age and life stage.
