Drinking alcohol is common among older adults, with nearly half of those aged 65 and above reporting consumption in the past year. However, as we age, our body's ability to process alcohol changes, and drinking can have more profound effects. These effects can include an increased risk of falls, medication interactions, increased risk of cancer, liver disease, and early mortality. Older adults may also find that their tolerance for alcohol decreases, and they experience stronger effects without increasing their consumption. Additionally, alcohol can worsen existing health conditions and interact dangerously with certain medications. As such, it is recommended that older adults limit their consumption or abstain from drinking altogether, especially if they have specific health conditions, take certain medications, or plan to drive or operate machinery.

What You'll Learn
Alcohol is metabolised differently by the body after 65
According to family medicine specialist Donald Ford, MD, "the basic process by which alcohol is metabolised doesn't change, but after age 65, several factors can alter the way you process it".
Circulation slows down
After 65, circulation slows down. "Less blood is flowing through your liver, so the process of metabolising alcohol slows, and more toxic metabolites may accumulate," says Dr. Ford.
Loss of lean muscle mass
As we age, we lose lean muscle mass. "Because we lose lean muscle mass with age, a higher concentration of alcohol remains in the bloodstream, says Dr. Ford. "So you feel more effects from the same amount of alcohol."
Development of chronic conditions
By the time we reach 65, we may have developed chronic conditions that require medication. "Alcohol competes with medicines for processing by your liver and wins," says Dr. Ford. This can cause issues with the effectiveness of medications such as sedatives, blood pressure medications, and blood thinners.
Sleep difficulties
Alcohol can compound the sleep difficulties that are common after age 65. While it may help people fall asleep, alcohol interrupts sleep, makes it less restful, and causes earlier awakenings.
Falls become more dangerous
As we age, we become more prone to falling, and the consequences of alcohol-related falls tend to be more serious after 65. "Tripping on a stair and hitting your head is far more likely to cause significant injury when you are older," says Dr. Ford.
Nutritional deficiencies
Drinking too much alcohol can put you at risk of nutritional deficiencies, which are more common among the elderly. "The consequences of nutritional deficiencies range from minor to major, says Dr. Ford. "Folate deficiency causes anemia in adults, but thiamine deficiencies can trigger delirium."

Alcohol affects older people more profoundly
As we age, our bodies change, and so does our ability to tolerate alcohol. There are several reasons why alcohol affects older people more profoundly.
Firstly, aging leads to a decrease in muscle mass and an increase in fat tissue. This change in body composition results in a higher blood alcohol concentration (BAC) in older adults compared to younger individuals. The amount of water in our bodies also decreases with age, further contributing to a higher BAC. This means that an older person who consumes the same amount of alcohol as a younger person will generally experience stronger effects.
Secondly, the processing of alcohol by the body slows down with age. The liver, which is responsible for metabolizing alcohol, receives less blood flow as we get older, leading to a slower breakdown of alcohol. This results in a higher concentration of alcohol remaining in the bloodstream, causing more pronounced effects.
Thirdly, older adults are more likely to be taking various medications for age-related health conditions. Alcohol can interact negatively with many prescription and over-the-counter medications, including those for anxiety, depression, allergies, and pain. Mixing alcohol with certain medications can be dangerous or even deadly.
Additionally, physical and mental functions, such as coordination, vision, hearing, and reflexes, tend to decline with age. When combined with the effects of alcohol, this can lead to a significantly increased risk of accidents, such as falls, slips, or car crashes.
Finally, aging can lower the body's tolerance for alcohol, and older adults generally experience the effects of alcohol more quickly than when they were younger. This increased sensitivity to alcohol can further heighten the risks associated with drinking.
In conclusion, while an occasional drink may be fine for older adults, it is important to recognize that alcohol affects them more profoundly due to physiological changes, decreased liver function, medication interactions, impaired physical and mental functions, and increased sensitivity to alcohol. Understanding these factors can help older adults make informed decisions about their alcohol consumption and minimize potential risks.

Alcohol can worsen health conditions
As we age, alcohol can worsen existing health problems and have dangerous interactions with medications. Alcohol can also impair a person's judgment, coordination, and reaction time, increasing the risk of falls, car crashes, and other accidents. Here are some specific ways in which alcohol can worsen health conditions:
- Increased risk of falls and injuries: Older adults are more prone to falling, and the consequences of alcohol-related falls tend to be more serious. Older people also have thinner bones, which break more easily. Alcohol increases the risk of balance problems and falls, leading to hip or arm fractures and other injuries.
- Interference with medication: Alcohol can interfere with the processing of prescription and over-the-counter medications. It competes with medicines for processing by the liver and can lead to dangerous interactions. For example, alcohol can increase the potency of sedatives and augment the effects of blood thinners, increasing the risk of serious bleeding.
- Worsening of health conditions: Alcohol can worsen certain health conditions such as osteoporosis, diabetes, high blood pressure, stroke, ulcers, memory loss, and mood disorders. It can also make some medical conditions harder to diagnose and treat, such as heart-related issues.
- Liver disease: Excessive drinking can lead to a toxic build-up of acetate in the liver, causing cirrhosis.
- Nutritional deficiencies: Drinking too much can put you at risk of nutritional deficiencies, which are more common among the elderly.
- Sleep disturbances: While alcohol may help you fall asleep, it interrupts sleep, makes it less restful, and causes earlier awakenings.
- Increased risk of certain cancers: Alcohol contributes to an increased risk of oral cancers and other types of cancer.
- Mental health issues: Alcohol misuse or heavy drinking can be linked to depression and anxiety in older adults.
- Impaired driving: Alcohol impairs judgment, coordination, and reaction time, increasing the risk of traffic accidents. This risk is higher for older drivers, who tend to be more seriously hurt in crashes.
- Social and relationship problems: Alcohol misuse can strain relationships with family and friends and, in extreme cases, contribute to domestic violence and child abuse or neglect.

Alcohol can have dangerous interactions with medication
As we age, our bodies process alcohol differently. After 65, circulation slows down, and less blood flows through the liver, which means that more toxic metabolites may accumulate in the body. Older people also tend to have developed chronic conditions that require medication, and alcohol can have dangerous interactions with many common prescription and over-the-counter medications.
Alcohol and Medication Interactions
Alcohol can interact with medications in two main ways: pharmacodynamic interactions and pharmacokinetic interactions. Pharmacodynamic interactions occur when a medication's side effects, such as drowsiness, are magnified by alcohol consumption. This added drowsiness can interfere with concentration, judgement, and the ability to operate machinery or drive a vehicle. Pharmacokinetic interactions occur when alcohol changes the processes of drug absorption, metabolism, or excretion. Alcohol and medications may compete for the same liver enzymes, which can cause medications to be less effective or to build up and cause toxic effects.
Common Medications that Interact with Alcohol
- High blood pressure medication
- Sleeping pills (sedatives and hypnotics)
- Pain medications (analgesics)
- Skeletal muscle relaxants
- Cholesterol medications
- Cardiovascular (heart) medications
- Central nervous system (CNS) agents like sedatives or narcotic pain relievers
- Metabolic medications, such as diabetes medicines
- Antidepressants
- Opioid painkillers
- Steroids (corticosteroids, or anti-inflammatory medications)
- Nonsteroidal anti-inflammatory drugs (NSAIDs)
- Herbal remedies such as kava kava, St. John's wort, chamomile, valerian, and lavender
Side Effects of Alcohol and Medication Interactions
- Nausea and vomiting
- Headaches
- Drowsiness
- Dizziness
- Fainting
- Loss of coordination
- Internal bleeding
- Heart problems
- Difficulties in breathing
- Liver damage
- Low or high blood pressure
- Falls or injury due to accidents
- Slowed breathing (respiratory depression)
Special Considerations for Older Adults
Older adults are at a higher risk of harmful alcohol-medication interactions. As we age, our bodies break down alcohol more slowly, so alcohol remains in the system longer and has a greater potential to interact with medications. Older adults are also more likely to be taking multiple medications that interact with alcohol. Additionally, older adults tend to have a lower percentage of body water relative to fat, which further increases the risk for complications.

Alcohol increases the risk of accidents
Additionally, as we age, we lose lean muscle mass, which means that a higher concentration of alcohol remains in the bloodstream, increasing the effects of alcohol. This can lead to a higher risk of falls, car crashes, and other unintentional injuries. Older adults are also more likely to be taking prescription medications, which can have dangerous interactions with alcohol.
Even a small amount of alcohol can affect driving ability. At a blood alcohol concentration (BAC) of 0.08 g/dL, crash risk increases exponentially, and it is illegal to drive at or above this limit in all 50 US states and Puerto Rico (with the exception of Utah, where the limit is lower, at 0.05). In 2022, there were 2,337 people killed in alcohol-related crashes where the driver had a BAC of 0.01 to 0.07 g/dL.
Furthermore, alcohol negatively affects our cognitive abilities and impairs our judgment, reasoning, muscle coordination, and reaction time, all of which are essential for operating a vehicle safely. As alcohol levels rise in a person's system, these negative effects on the central nervous system increase.
The more you drink, the greater the effect, and the risk of crashing is even greater for young males. Drivers with a BAC of 0.08 are approximately four times more likely to crash than drivers with a BAC of zero, and at a BAC of 0.15, drivers are at least 12 times more likely to crash.
In summary, alcohol significantly increases the risk of accidents, especially for older adults due to their reduced ability to process alcohol and increased sensitivity to its effects. Driving under the influence of alcohol is illegal and extremely dangerous and can lead to serious injuries and fatalities.
