Alcohol and PAD (Peripheral Arterial Disease): What to Know

Alcohol and PAD. Peripheral arterial disease (PAD) is caused by plaque (fat and cholesterol) in the arteries that supply the legs. The plaque narrows the arteries and decreases blood flow. It usually causes leg problems. The most common symptom of PAD is leg pain while walking. That’s claudication.

Over 200 million people around the world suffer the disease. This is important. That’s because PAD increases the risk of heart attack and stroke. People want to know the answer to a simple question. Are drinking alcohol and PAD related? And if so, how?

I. Other Symptoms of PAD

    • alcohol and PADChange in leg color.
    • Coldness in leg or foot.
    • Erectile dysfunction.
    • Leg numbness or weakness
    • Loss or slower hair growth on leg or foot.
    • Painful cramping in hip, thigh, or calf muscles when walking.
    • Shiny skin on leg.
    • Slower growth of toenails.
    • Sores on legs, feet, or toes that don’t heal.
    • Weak pulse in leg or foot.

II. Research on Alcohol and PAD

Strong Health Study

The Strong Heart Study involved 4,549 people the aged 45-74 years. Researchers found that those who drank alcohol were less likely to have PAD. It’s important that the researchers controlled for relevant factors. That is, they took into consideration such things as age, blood pressure, and cholesterol levels. That’s because such things are possible other reasons for the link.

Research generally finds that that the health benefits of drinking doesn’t depend on the form of alcohol. That is, beer, wine, and spirits (liquor) tend to have the same health benefits.

Rotterdam Study

The Rotterdam Study was in the Netherlands. Researchers studied 3,975 people aged 55 and older. They controlled relevant factors. The study found that drinking alcohol reduced PAD among non-smokers. It also found that among smoking women but not among smoking men.

Physicians’ Health Study

The Physicians’ Health Study is a randomized trial of 22, 071 male doctors in the U.S. Researchers followed them for 11 years. During that time 433 developed PAD.

The researchers controlled for age, smoking, exercise, diabetes, and family history of heart attack. They defined daily drinkers as having seven or more drinks per week. Then they compared them to those who had less than one drink per week. Daily drinkers had 16% lower risk of PAD.

Framingham Heart Study

alcohol and PADThe Framingham Heart Study is a population-based cohort study that began in 1948 in Framingham, MA. Researchers are now studying the third generation of people. They examined intermittent claudication (IC), a major symptom of PAD. 

The study controlled for many factors. It found that the greatest reduction in IC risk was at about one to two daily drinks for men. For women, it was at about one-half to one drink per day.

III. Risk Factors

You can control these risk factors. That is, things that increase your risk of PAD.

    • Not drinking alcohol in moderation.
    • Cigarette smoking.
    • Diabetes
    • High blood pressure.
    • High cholesterol. 
    • Obesity 
    • Physical inactivity.
