Hepatologist and gastroenterologist Sergey Vyalov told why it is dangerous to take iron preparations without a prescription and what is the danger of iron excess in the body, MedicForum reported.

Most people today are concerned about the opposite problem - how to increase iron levels in the body and raise ferritin? Low iron is fraught with a drop in hemoglobin, and one may not be far from anemia. But just as serious are the consequences of an overabundance of iron. 

When iron becomes too much, and the body does not have time to consume it, the liver is subjected to enormous overload, so powerful that it leads to its destruction. 

"It is categorically not recommended to take iron for prophylaxis without having first undergone the appropriate tests, especially in high doses," the doctor said.
