Low levels of carbon monoxide can lead to carbon monoxide symptoms that are not always obvious or present themselves in the same way as another ailment such as cold or flu – making this silent killer even more dangerous as it can be too late before you realise there is a problem.
The most common carbon monoxide poisoning symptoms for low levels of CO are as follows:
- dizzy spells
- stomach pain
- nausea and vomiting
- shortness of breath and difficulty breathing
The above symptoms will get worse the longer you continue to inhale carbon monoxide gas – sometimes rapidly (within two hours) dependant on the levels of CO. Long-term exposure to low levels of CO can result in mood swings, becoming increasingly agitated or depressed. You may also find you have difficulty concentrating or making decisions.
