Alcohol consumption and stroke: benefits and risks.
alcohol consumption is associated with a lower risk for ischemic stroke. The purpose of this study hemorrhagic stroke in relation to alcohol drinking patterns . What you need to know. If you have had a haemorrhagic stroke, you must not drink alcohol for at least three weeks after your stroke. Drinking too much alcohol . Analyzing the link between alcohol and stroke. Researchers from the Karolinska Institute in Sweden and the University of Cambridge in the.
Alcohol and stroke risk Drinking too much alcohol contributes to a number of risk factors for stroke. If you have already had a stroke or transient ischaemic attack TIAyou can help reduce your risk of having another stroke by only drinking a safe amount of alcohol.
High blood pressure is the biggest risk factor for stroke, and drinking too much alcohol raises your blood pressure. Atrial fibrillation, which is a type of irregular heartbeat, can be triggered by drinking too much alcohol. Diabetes and being overweight also increase your risk of having a stroke. Both of these risk factors are linked to drinking too much alcohol.
Alcoholic drinks are high in calories and they do not have any nutritional value. Reducing the amount of alcohol you drink can help you achieve and maintain a healthy weight. Haemorrhagic stroke and alcohol A haemorrhagic stroke is caused by a break in the wall of a blood vessel in the brain. If you have had a haemorrhagic stroke, you must not drink alcohol for at least three weeks after your stroke.
Ask your doctor when it is safe to start drinking alcohol again. Drinking alcohol after a stroke Alcohol could interfere with the medicine you take to reduce your risk of having another stroke.
In particular, it can be harmful if you are taking blood-thinning medicine such as Warfarin. Talk to your doctor about whether it is safe to drink alcohol while taking medicine. Consuming alcohol safely The National Guidelines for Alcohol Consumption gives advice about safe amounts of alcohol. Remember, the Guidelines are for healthy people. Talk to your doctor about whether it is safe for you to drink at all, and whether the amounts in the Guidelines are safe for you.
The Guidelines state that healthy men and women should not drink more than two standard drinks on any day. This will reduce the long-term risk of harm from alcohol.

Guidelines also say you should not drink more than four standard drinks on one occasion. This will reduce the short-term risk of harm from that occasion, such as falls or accidents.
For spirits with 40 percent alcohol by volume, a standard drink is 30 mls. A ml glass of full-strength beer is 1.
Levels of alcohol consumption were evaluated using patients' self-reporting. Participants answered a series of questions using a questionnaire or an interview. Using standardized measures of alcohol, alcohol consumption was divided into four categories: The study adjusted for variables such as age, sex, smoking, body mass index BMIand diabetes. Results were published in the open-access journal BMC Medicine.
Alcohol may increase the risk of hemorrhagic stroke The meta-analysis looked at two different types of stroke: Ischemic stroke is the most common type of stroke.
It is caused by a blood clot blocking the flow of blood and oxygen from reaching the brain. A hemorrhagic stroke occurs either when an aneurysm bursts, or a weakened blood vessel leaks. The result is bleeding either inside the brain, causing an intracerebral hemorrhage, or, less commonly, bleeding between the brain and the tissue covering it, causing a so-called subarachnoid hemorrhage.
The study revealed that light and moderate alcohol consumption seemed to lower the risk of ischemic stroke, but it had no impact on the risk of developing hemorrhagic stroke. Susanna Larsson, lead author of the study, explains why this may be: This may explain the association between light to moderate alcohol consumption and lower ischemic stroke risk.
This is more apparent when looking at the heavy drinking category. The association between heavy alcohol consumption and these two types of stroke was stronger than that for ischemic stroke.

Susanna Larsson Therefore, even if moderate drinking may have a beneficial effect by lowering the risk of ischemic stroke, the disadvantages might outweigh the benefits. Strengths and limitations of the study Dr.
Larsson points out that the large sample size included in the analysis allowed for accurate associations between a wide range of alcohol consumption patterns and patient subgroups.
