Alcohol affects the body more as you age, even with the same amount

Experts say that with age the same amount of alcohol can lead to higher blood alcohol levels and stronger effects because of shifts in body composition and slower liver processing.

Dry January has prompted many Americans to reassess drinking as they notice that alcohol no longer produces the same effects it once did. Experts report this shift often begins in the late 30s and early 40s. Physicians explain the body processes alcohol differently with age because liver enzymes slow and body composition shifts. For some women, menopause and hormonal changes can further change how alcohol affects them. Key points: - The same amount of alcohol can produce a higher blood alcohol concentration in older adults, according to experts and reporting from Harvard Health. - Age-related changes that affect alcohol processing include slower liver enzyme activity, reduced lean muscle, increased body fat, and lower total body water. - Hormonal changes in menopause can intensify alcohol’s effects and slow recovery for some women. - Research on hangover severity is mixed; some studies report fewer or less severe hangovers in older adults, while subjective experience may worsen due to increased pain sensitivity, poorer sleep, and higher inflammation. - Public health groups and clinicians note greater long-term risks with age, including falls, medication interactions, high blood pressure, cognitive decline, and cancer; alcohol is classified as a Group 1 carcinogen. - Some geriatricians and other clinicians report discussing alcohol use with aging patients as part of routine care. Summary: Aging alters how the body handles alcohol, increasing short-term effects and contributing to several long-term health risks; experts say these changes often appear by midlife. Undetermined at this time.
