What is the Effect of Alcohol on Blood Pressure?

Alcohol can cause several of your body functions to go haywire, your blood pressure chiefly among them. Drinking a small to moderate quantity of alcohol (10 to 28 g) can initially lower your blood pressure for up to 12 hours, beyond which it spikes your blood pressure levels. Long term alcohol consumption or heavy drinking is associated with elevated blood pressure levels (>130/80 mm Hg) and hypertension (>140/90 mm Hg). 

Alcohol is thought to raise your blood pressure through the following mechanisms:

  • Heavy alcohol consumption triggers the release of a hormone called renin, which regulates sodium levels and electrolyte balance in your body as a part of the Renin-Angiotensin-Aldosterone System (RAAS). Increased activity of renin in your blood can lead to the production of angiotensin I and angiotensin II, hormones that cause your blood vessels to constrict, which raises your blood pressure levels. Angiotensin II also stimulates the release of aldosterone, a hormone that retains sodium and water in your body, further increasing your blood pressure.
  • Alcohol interferes with the release and functioning of nitric oxide, which is a vasodilator. Due to this, your arteries remain tense or constricted, which increases your blood pressure.
  • Long term alcohol consumption is also linked to increased cortisol (stress hormone) levels in your body. Increased levels of cortisol are linked to an elevation in your heart rate and blood pressure levels.

How Much Alcohol Can You Safely Consume With High Blood Pressure?

Though a moderate consumption of alcohol is associated with improvement in heart health, any consumption of alcohol leads to increased blood pressure levels. For this reason, most people with hypertension are advised to quit alcohol or limit their consumption to one drink a day in women and two drinks a day in men. 

The following are the recommended quantities of consumption for different types of alcohol.

  • Beer: 1 drink = 12 ounces or 355 ml
  • Red wine: 1 drink = 5 ounces or 148 ml
  • Hard liquor: 1 drink = 1.5 ounces or 44 ml
  • Total alcohol consumption: 10 to 12 g a day (calculated based on the quantity and strength of the drink consumed).

What Type of Alcohol Can Hypertensives Safely Consume?

If you have hypertension, having any amount of alcohol can spike your blood pressure. So instead of alcoholic beverages, try drinking non-alcoholic wine or beer. Hard liquor (distilled drinks like whiskey, gin, vodka, rum, etc.) should be avoided.

Are There Any Risks of Over Consuming Alcohol?

Regular and excessive alcohol consumption can lead to the following health problems:

  • Impaired judgment and mental faculties
  • Liver damage
  • Damage to the pancreas
  • Increased risk of diabetes
  • High blood pressure
  • High cholesterol levels
  • Weight gain and obesity
  • Increased risk of heart attack, stroke, and cardiovascular damage
  • Increased risk of developing cancer (especially breast cancer in women)
  • Weakened immune system
  • Interpersonal issues that can adversely affect social, professional, and familial relationships and mental health
  • Alcohol poisoning, alcohol dependence, and addiction
  • Sexual dysfunction and decreased fertility in men
  • Increased risk of miscarriage in pregnant women
  • Stillbirth or developmental challenges in children born of women who consumed alcohol during pregnancy

Are There Any Possible Health Benefits of Alcohol Consumption?

The benefits offered by alcohol would depend on your age, gender, health, and any medications you are taking, etc. The risks of alcohol consumption may outweigh the benefits if you have prior health conditions like metabolic syndrome, high blood pressure, diabetes, liver or kidney dysfunction, or if you are pregnant or taking any medications.

  • In healthy individuals, moderate alcohol consumption may improve heart health and decrease your chances of having a heart attack or stroke.
  • Mild to moderate alcohol consumption may also help you relax and de-stress, thus improving your mood.
  • Some types of alcohol like red wine and whiskey have polyphenols, substances with antioxidant properties that are also found in abundance in tea and dark chocolate. These polyphenols can help lower low-density lipoprotein (LDL or bad) cholesterol levels and also improve the high-density lipoprotein (HDL or good) cholesterol levels in your body.
