Patient's question:

Sure, here is the translation of the content you provided, with the exception of the "" which remains unchanged:
"Multi"

Doctor's answer:

Analysis of the condition: Blood lead levels should typically not exceed 100 units, and the ideal level is zero in the human body. However, excessive lead absorption through ingestion and inhalation can affect appetite, growth, and even cause anemia, hyperactivity, and other conditions. Therefore, in addition to advising on preventive measures, professional doctors may recommend taking some lead-excreting health supplements. Generally, a follow-up check is conducted after taking them for 2 months. If the level has dropped below 50 units, the supplements can be discontinued, but it is still necessary to continue taking fish oil and calcium regularly. Maintaining a high level of calcium and zinc in the body can inhibit the absorption of lead.
The "Qianguhua Oral Liquid" used in Shanghai, taken once daily, generally shows some effect in children. It also has nutritional benefits. It is recommended to take it under the guidance of a specialist doctor in your area, as health supplements available in different regions may vary.
Suggestions: The common clinical manifestations of lead's impact on children's neurobehavioral development include hyperactive behavior, such as distracted attention, impulsivity, and excessive liveliness. This is because lead poisoning can disrupt the brain's excitatory and inhibitory functions; inactivate and degenerate brain activity proteins, leading to the death of certain brain cells and the cessation of related functional activities; damage the blood-brain barrier, allowing excessive amounts of water and toxins from the blood to enter brain tissue, causing cerebral edema; and prevent synchronized neurodevelopment, disrupting the brain's network structure and impairing integration and coordination functions.
