Symptoms of Carbon Monoxide Poisoning and When to Seek Medical Attention

Carbon monoxide (CO) is a colorless, odorless gas produced by incomplete burning of fuels such as wood, coal, gas, and oil. When inhaled, the gas binds to hemoglobin in the blood and prevents oxygen from getting to the body’s tissues, resulting in carbon monoxide poisoning.

Symptoms of carbon monoxide poisoning can vary and are often mistaken for flu-like symptoms.

Common symptoms include:

  • Headache
  • Nausea and vomiting
  • Dizziness and lightheadedness
  • Fatigue
  • Shortness of breath
  • Chest pain
  • Mental confusion
  • Loss of consciousness

If you’re experiencing any of the above symptoms, it’s important to seek medical attention immediately. Carbon monoxide poisoning can be fatal if left untreated.
