Which of these therapies may be used to treat iron overload?

Question

Quizplus · Accepted Answer

Chelation therapy is the most common therapy used to treat iron overload. Chelation agents are drugs that bind to excess iron in the body and remove it through urine or feces. Other therapies, such as gastric bypass surgery, may indirectly help with iron overload by reducing the amount of iron absorbed from food, but they are not direct treatments. Vitamin C supplements and calcium supplements are not recommended for iron overload as they can actually increase iron absorption. Blood transfusions are used to treat anemia, which can sometimes be a result of iron overload, but are not a direct treatment for iron overload itself.
