What physiological changes are seen during alcohol withdrawal syndrome?

In alcohol withdrawal syndrome, one of the hallmark physiological changes is an increase in heart rate and heightened agitation. This occurs because the body, which has adapted to the presence of alcohol, begins to react to its absence. Alcohol typically has a depressant effect on the central nervous system; therefore, withdrawal leads to increased sympathetic nervous system activity.

As the body struggles to regain homeostasis, symptoms such as tachycardia (increased heart rate) and anxiety or agitation become pronounced. These responses are part of the body's effort to reestablish balance after the sudden removal of a substance it has become dependent on. It's common for patients to experience additional symptoms such as tremors, sweating, and potentially severe complications like delirium tremens. Understanding these signs is crucial for nurses and healthcare providers in order to monitor and manage patients during this critical time effectively.
