Decreased blood pressure. While alcohol withdrawal can lead to changes in blood pressure, the more common manifestation is an increase in blood pressure due to sympathetic overactivity. Increased heart rate is usually observed as well, and it's a more sensitive indicator of alcohol withdrawal than decreased blood pressure.

Decreased heart rate. Alcohol withdrawal often results in increased sympathetic activity, leading to elevated heart rate (tachycardia). The withdrawal-related increase in heart rate is a result of the autonomic nervous system's response to the abrupt cessation of alcohol's depressant effects. This is a more typical manifestation of alcohol withdrawal than decreased heart rate.

Hyperthermia. While alcohol withdrawal can cause an increase in body temperature, it's not one of the primary manifestations. The central nervous system hyperactivity associated with alcohol withdrawal is more likely to cause symptoms like anxiety, tremors, and seizures, rather than hyperthermia.

Hyperglycemia. Hyperglycemia is not a common manifestation of alcohol withdrawal. Instead, alcohol withdrawal is more commonly associated with hypoglycemia due to the effects of alcohol on liver function and glucose regulation.
