Can an opioid overdose cause brain lesions on both sides of the brain?
Yes, an opioid overdose can potentially cause bilateral brain lesions. This happens because opioids can slow breathing to dangerously low levels, a condition called respiratory depression.
When breathing becomes too shallow or stops, oxygen levels in the blood drop severely. This lack of oxygen can damage brain tissue on both sides of the brain, potentially leading to lesions.
The brain is extremely sensitive to oxygen deprivation. Even a few minutes without adequate oxygen can cause permanent damage to brain cells throughout the brain, not just in one area.
This is why opioid overdoses are medical emergencies. If you suspect someone is overdosing, call 911 immediately and administer naloxone if available. Naloxone can quickly reverse the overdose by blocking opioids from working and restoring normal breathing.
Signs of an opioid overdose include:
- Losing consciousness
- Extremely small pupils
- Very slow or shallow breathing
- Choking or gurgling sounds
- Limp body
- Purple lips or fingernails
- Cold, pale, or bluish skin
Quick medical intervention is critical to prevent brain damage and save lives.
