Generally, according to the amount of lead in patients’ bodies, different methods are adopted to excrete lead from the body clinically. First, if the lead content in the patient’s body is mildly elevated, the excess lead in the body can be excreted by increasing water intake and forming urine through the kidneys. Patients can eat more protein-rich foods such as eggs, milk, lean meat, etc., which can form compounds not easily absorbed with lead and reduce the absorption of lead by the body. Patients can also eat more fresh vegetables and fruits, as well as crude fiber-rich foods such as cucumber, tomatoes, fungus, sweet potatoes, corn, etc. to excrete the lead in the body through feces. Secondly, if the lead level in the patient’s body is obviously elevated and the lead needs to be excreted through drugs, it is recommended to be hospitalized in time, because the drugs for excreting lead contain obvious side effects and need to be used under the guidance of doctors.
