Cyanide poisoning occurs when cyanide, a highly toxic chemical, enters the body. It can be found in certain industrial processes, as well as in some seeds and fruit pits, such as those from apricots and cherries. When inhaled, ingested, or absorbed through the skin, cyanide prevents cells from using oxygen, leading to rapid cellular suffocation. Symptoms of cyanide poisoning include headache, dizziness, confusion, and difficulty breathing. In severe cases, it can result in loss of consciousness and death. Immediate medical attention is crucial, and treatments may involve administering hydroxocobalamin or sodium thiosulfate to help neutralize the toxin.
