KEY POINTS<br />

• Binge drinking (too much too fast ) is a pattern corresponds to consuming 5 or more drinks<br />

(male), or 4 or more drinks (female), in about 2 hours.<br />

• Binge drinking while fasting may result in hypoglycemia and severe lactic acidosis.<br />

• Binge drinking may precipitate acute severe alcoholic hepatitis (AH) against a background <strong>of</strong><br />

chronic liver disease. Thirty day mortality in patients with severe AH may exceed 40%.<br />

• If you drink, drink moderately with food.<br />

PATTERN OF DRINKING<br />

In <strong>the</strong> United States, <strong>the</strong> pattern <strong>of</strong> drinking is divided into three categories: moderate, low-risk, and high risk.<br />

• Moderate drinking, according to <strong>the</strong> U.S. dietary guidelines, is up to 2 drinks per day <strong>for</strong> men and up to<br />

1 drink per day <strong>for</strong> women. Obviously, <strong>the</strong> definition <strong>of</strong> moderate drinking varies in different countries.<br />

• Low-risk drinking is not just ano<strong>the</strong>r term <strong>for</strong> "moderate" drinking, even though <strong>the</strong> weekly amounts may<br />

be <strong>the</strong> same, but <strong>the</strong> daily ones are different; <strong>the</strong> recommendations serve different purposes <strong>for</strong> different<br />

types <strong>of</strong> drinkers. Low-risk drinking <strong>for</strong> healthy men under age 65 is no more than 4 drinks on any day and<br />

14 per week, and <strong>for</strong> healthy women (and men over 65) is no more than 3 drinks on any day and 7 per week.<br />

• High-risk drinking comprises: 1) binge drinking (too much too fast - A “binge” is a pattern <strong>of</strong> drinking<br />

alcohol that brings blood alcohol concentration (BAC) to 0.08 gram percent or above. For <strong>the</strong> typical adult,<br />

this pattern corresponds to consuming 5 or more drinks (male), or 4 or more drinks (female), in about 2<br />

hours; and 2) chronic heavy drinking (drinking too much too <strong>of</strong>ten).<br />

BINGE DRINKING AND THE LIVER<br />

While drinking too much and too <strong>of</strong>ten over a long period <strong>of</strong> time results in alcoholic liver disease (ALD),<br />

which encompasses fatty liver, steatohepatitis, liver fibrosis and cirrhosis, and may proceed to hepatocellular<br />

carcinoma, binge drinking can lead to glycogen depletion, which would be aggravated in <strong>the</strong> presence <strong>of</strong><br />

liver disease, and may lead to acidosis and hypoglycemia. In addition, people who drink heavily tend to<br />

have hyperuricemia and hypertriglyceridemia, which may exacerbate diabetic hypertriglyceridemia.<br />

Correlation <strong>of</strong> Quantity and Frequency <strong>of</strong> Drinking and <strong>Liver</strong> Damage:<br />

The effects <strong>of</strong> drinking too much too fast, or too much too <strong>of</strong>ten on <strong>the</strong> liver have been sparingly studied.<br />

Past studies focused on <strong>the</strong> incidence <strong>of</strong> cirrhosis among alcoholics (Lelbach et al., 1975), or sought <strong>the</strong><br />

clinical manifestations <strong>of</strong> alcoholism among cirrhotic patients (Caroli et al.,). In <strong>the</strong>se two approaches,<br />

<strong>the</strong> quantity <strong>of</strong> alcohol consumed and <strong>the</strong> drinking pattern were undetermined. A third indirect approach<br />

attempted to correlate average quantities <strong>of</strong> alcohol consumption (based on demographic and economic<br />

statistics) with cirrhosis mortality. This approach, however, did not measure <strong>the</strong> quantity and frequency <strong>of</strong><br />

alcohol consumption, and did not provide in<strong>for</strong>mation on individual consumption and risk.<br />

In a prospective study, Kamper-Jørgensen and colleagues (2004) interviewed a cohort <strong>of</strong> 6152 alcoholabusing<br />

men and women about <strong>the</strong>ir drinking pattern, frequency <strong>of</strong> alcohol intake, duration <strong>of</strong> alcohol<br />

misuse, and beverage type. The rate <strong>of</strong> alcoholic cirrhosis mortality in men and women was, respectively,<br />

27- and 35-fold <strong>the</strong> rate <strong>of</strong> <strong>the</strong> Danish general population. They also reported that “alcohol has a threshold<br />

effect ra<strong>the</strong>r than a dose-response effect on mortality from alcoholic cirrhosis.”
