Withdrawal is not only uncomfortable. It puts real strain on the heart and blood vessels, and the risks depend on the substance.
Alcohol withdrawal
The nervous system, held down by alcohol, rebounds into overdrive. Blood pressure and heart rate climb, with sweating, tremor and anxiety. In severe cases, including delirium tremens, heart rhythm problems and dangerous blood pressure spikes can occur. Alcohol withdrawal should be medically supervised.
Opioid withdrawal
Heart rate and blood pressure rise modestly, with sweating, goosebumps, yawning, diarrhea, vomiting and aches. It is rarely life-threatening for healthy adults, but dehydration from vomiting and diarrhea can strain the heart, and the misery drives return to use.
Sedative withdrawal
Stopping benzodiazepines or similar sedatives abruptly after regular use can cause dangerous withdrawal, including seizures. Taper only with medical guidance.
Who is at higher risk
People with heart disease, high blood pressure, older adults and anyone who has had severe withdrawal before should withdraw under medical care.
