Drinking alcohol regularly, especially in larger amounts, raises blood pressure over time and is a common, reversible cause of hypertension. Heavy or binge drinking can also trigger irregular heart rhythms (sometimes called 'holiday heart'), weaken the heart muscle over years, raise triglycerides, and contribute to weight gain.
Reducing or stopping alcohol can lower blood pressure within weeks and brings wider heart and general health benefits. Health guidelines suggest keeping within low-risk limits, and there is no need to start drinking for any supposed heart benefit, as the risks outweigh it.
If you have high blood pressure, an irregular heartbeat or take heart medicines, ask your doctor or pharmacist about alcohol, since it can interact with some medications. If you find it hard to cut down, your doctor can offer support.
