In general, whether mercury poisoning can be self-cured depends on the severity of the symptoms and the dose of the poisoning. Mild mercury poisoning can be self-cured, but if the mercury poisoning is severe, it cannot be self-cured and must be treated through regular treatment to get better. In daily life, consuming aquatic products with excessive mercury content, etc. can easily cause mercury poisoning, and patients with mild mercury poisoning will experience dizziness, headache and stomatitis. Patients can promote self-healing of mercury poisoning in the body by eating more fresh fruits and vegetables and paying attention to rest. Large amounts of mercury poisoning are usually caused by excessive inhalation of mercury from occupations such as mercury mining, smelting of amalgams, and pharmaceuticals, leading to mercury poisoning. After a large amount of mercury enters the body, it is distributed in all tissues and organs through the blood circulation, and the metabolism of mercury is very slow, and the patient will have symptoms such as loose teeth, agitation, and easy anxiety. At this time, mercury poisoning cannot be cured by itself, and must be treated through regular treatment to get better.
