Adults of any age can have problems with alcohol. In general, older adults don’t drink as much as younger people, but they can still have trouble with drinking. As people get older, their bodies change. They can develop health problems or chronic diseases. They may take more medications than they used to. All of these changes can make alcohol use a problem for older adults.
Alcohol, also known as ethanol, is a chemical found in beverages like beer, wine, and distilled spirits such as whiskey, vodka, and rum. Through a process called fermentation, yeast converts the sugars naturally found in grains and grapes into the alcohol that is in beer and wine. Another process, called distillation, concentrates alcohol in the drink making it stronger, producing what are known as distilled spirits.
Limited research suggests that sensitivity to alcohol’s health effects may increase with age. As people age, there is a decrease in the amount of water in the body, so when older adults drink, there is less water in their bodies to dilute the alcohol that is consumed. This causes older adults to have a higher blood alcohol concentration (BAC) than younger people after consuming an equal amount of alcohol.
This means that older adults may experience the effects of alcohol, such as slurred speech and lack of coordination, more readily than when they were younger. An older person can develop problems with alcohol even though his or her drinking habits have not changed.
Drinking too much alcohol can cause health problems. Heavy drinking over time can damage the liver, the heart, and the brain. It can increase the risk of developing certain cancers and immune system disorders as well as damage muscles and bones.
Drinking too much alcohol can make some health conditions worse. These conditions include diabetes, high blood pressure, congestive heart failure, liver problems, and memory problems. Other health issues include mood disorders such as depression and anxiety. Adults with major depression are more likely than adults without major depression to have alcohol problems.
Many older adults take medicines, including prescription drugs, over-the-counter (non-prescription) drugs, and herbal remedies. Drinking alcohol can cause certain medicines not to work properly and other medicines to become more dangerous or even deadly. Mixing alcohol and some medicines, particularly sedative-hypnotics, can cause sleepiness, confusion, or lack of coordination, which may lead to accidents and injuries. Mixing medicines also may cause nausea, vomiting, headaches, and other more serious health problems.
Medications stay in the body for at least several hours. So, you can still experience a problem if you drink alcohol hours after taking a pill. Read the labels on all medications and follow the directions. Some medication labels warn people not to drink alcohol when taking the medicine. Ask a doctor, pharmacist, or other health care provider whether it’s okay to drink alcohol while taking a certain medicine.
