A selenium overdose can cause a condition called selenosis, which leads to various health problems.
Understanding Selenosis
Selenosis, or selenium toxicity, occurs when there is an excessive amount of selenium in the body. While selenium is an essential trace element needed for various bodily functions, too much of it can be harmful.
Symptoms of Selenosis
The symptoms of selenosis can vary depending on the severity of the toxicity. According to the reference material, a selenium overdose can cause:
- Skin lesions
- Nervous system abnormalities
In severe cases, selenosis can lead to more serious health issues, including:
- Tremors
- Kidney failure
- Cardiac failure
- Respiratory distress
- Death
Rarity of Selenosis
Fortunately, severe selenosis is rare in the United States. However, it's still important to be mindful of selenium intake through diet and supplements.
Selenium: Essential vs. Toxic
| Aspect | Selenium Deficiency | Selenium Toxicity (Selenosis) |
|---|---|---|
| Cause | Insufficient dietary intake | Excessive intake through diet or supplements |
| Common Symptoms | Weakened immune system, thyroid issues | Skin lesions, nervous system abnormalities, tremors, kidney/cardiac failure |
| Rarity | More common than selenosis in developed countries | Rare, especially in the United States |
| Treatment | Selenium supplementation under medical supervision | Cessation of selenium intake and supportive medical care |
