ABSTRACT
Alcohol is readily absorbed into the bloodstream from the stomach, small intestine, and colon, given its water solubility. It is distributed to all tissues. Calculations of the prevalence of alcohol use disorder vary greatly depending upon the methods employed. The percentage of respondents with alcohol use disorder in the prior 12 months who sought help or treatment was 7.7; among those with alcohol use disorder in their lifetime, the percentage was 19.8. It has also been established that family history of alcohol use disorder increases the likelihood of developing a use disorder and therefore including this in family history taking is a relevant part of screening. Alcohol use disorder among physicians is common: 10–12% of doctors develop a substance use disorder, of which alcohol use disorder is the most prevalent, at about 50%. Symptoms of alcohol withdrawal include hypertension, tachycardia, diaphoresis, tremulousness, dilated pupils, disorientation, hyperarousal, and seizures.
