CO TOXICITY: SYMPTOMS
CO toxicity mimics a wide range of conditions: the symptoms of acute exposure are well-known, and include headache, nausea and drowsiness.
Chronic exposure to low levels also damages the heart, brain and other tissues. Its effects can be wide-ranging, and include -
fatigue
low or unstable mood
cognitive decline
loss of vision
loss of hearing
other neurological disorders, such as tremor
impaired cardiac performance
Of note, end-organ damage due to CO inhalation can in some cases accumulate subclinically, with symptoms only becoming apparent after long-term exposure.
Children and the unborn are especially vulnerable to CO poisoning, which can also lead to -
stillbirth
low birth weight
developmental delay
behavioural disorders
If you are concerned that you or your family may have been exposed to CO, please consult a health professional without delay.
