What it feels like
Even a single glass can leave you flushed, dizzy, or hungover. You might feel overly tipsy, wake up sweating in the night, or notice a racing heart—like your body suddenly can’t process alcohol the way it used to.
Why it catches you off-guard
You’ve likely been drinking for decades with no issues. Then suddenly, your favorite drink makes you feel awful.

What's really happening
As your hormones shift during perimenopause and menopause, your body changes the way it processes alcohol. You may feel tipsy faster, have worse hangovers, or experience hot flashes, headaches, and heart racing after just one drink.
As your hormones shift during perimenopause and menopause, your body changes the way it processes alcohol. You may feel tipsy faster, have worse hangovers, or experience hot flashes, headaches, and heart racing after just one drink.
But why?
Lower estrogen, decreased liver efficiency, and less body water all contribute to heightened alcohol effects.
Lower estrogen, decreased liver efficiency, and less body water all contribute to heightened alcohol effects.
Scientific Breakdown
As you age, your liver becomes less efficient at metabolizing both alcohol and hormones. This means alcohol lingers longer, interferes with hormone clearance, and can increase symptoms like night sweats, mood swings, and poor sleep. Decreased water retention and alcohol-processing enzymes in women intensify its effects, often leading to stronger intoxication and hangovers.
Estrogen & progesterone fluctuate → increased sensitivity
Liver function slows → alcohol stays in system longer
Less body water → alcohol is more concentrated

Essentially…
Your body simply doesn’t process alcohol like it used to. The enzymes that break down alcohol are lower. Your liver is multitasking more than ever. And estrogen dips make you more vulnerable to the effects. That fun glass of wine now acts like a double shot of espresso—plus a diuretic and a sleep disruptor.

Lifestyle Suggestions
Dr. Flagg's Alcohol Strategy
While ZERO alcohol is by far the best for health span, that's no fun. Alcohol, after all, is a common part of the fabric of our culture.
#1 Anything you do daily is a habit. There are good habits and bad habits. Daily alcohol is a bad habit. Have some alcohol free days.
#2 When you drink, have 1 or maybe two, not 3 drinks. Start with a glass of water, sip on 1/2 a drink, have another glass of water then drink the other 1/2.
#3 We all know this saying! "Do not drink alone!" When you drink- socialize + interact. Keep that brain engaged in meaningful ways. We have scientific data showing very clear benefits of socializing and engaging.
A couple more more tips:
Drink earlier in the evening, not before bed
Eat before and during drinking

Myth-Busting
Wine might feel relaxing at first—but it often disrupts sleep, worsens hot flashes, and raises health risks. During menopause, wine may be the reason you’re wide awake at 3am.

Modern Guidance
Most experts now recommend no more than one drink per day for women, and even less during menopause. Pay attention to how alcohol affects your sleep, mood, and symptoms. Cutting back—even a little—can make a noticeable difference.
