A recent study reported that there is a blood type that can influence the risk of early stroke.

The study said, according to the Science Alert website, that people who have blood type A are more likely to have a stroke before age 60 than people who have other blood types.

The study, prepared in 2022, which included genomic research, showed a clear relationship between the A1 subgroup gene and early stroke.

The researchers combined data from 48 genetic studies, which included nearly 17,000 people who had had a stroke and nearly 600,000 people without strokes. The ages of all participants ranged from 18 to 59 years.

The study found that people whose genomes were coded for a variety of blood types were 16 percent more likely to have a stroke before age 60, compared with a group of other blood types.

For those with the O1 group gene, the risk was 12 percent lower.

However, the researchers noted, the additional risk of stroke in people with type A blood is small, so there’s no need for extra vigilance or screening in this group.

“We don’t yet know why type A blood poses a higher risk,” said Stephen Kitner, senior author of Neurology and Vascular Sciences at the University of Maryland, in a 2022 statement.

“But it’s likely related to blood clotting factors such as platelets, the cells that line blood vessels, as well as other circulating proteins, all of which play a role in blood clot formation,” he added.

People in the study lived in North America, Europe, Japan, Pakistan and Australia, and people of non-European ancestry made up just 35% of the participants. Future studies with a more diverse sample could help clarify the significance of the findings.

“It is clear that we need more follow-up studies to elucidate the mechanisms of increased stroke risk,” Kittner said.

The authors say strokes in young adults are less likely to be caused by the buildup of fatty deposits in the arteries (a process called atherosclerosis) and more likely to be caused by factors related to clot formation.

The study also found that people with type B blood were about 11 percent more likely to have a stroke than people without strokes, regardless of their age. The genetic sequences of blood types A and B were also associated with a slightly increased risk of blood clots in the veins, which is called venous thrombosis.

Winter can affect our health in many ways, and health experts suggest that during the coldest months, the drop in temperature can have unexpected effects on the heart, further increasing the risk of stroke.

A stroke occurs when there is a sudden loss of brain cells or the death of brain cells due to blood deposits following a blockage in an artery.

And in this regard, Dr. Kunal Bahrani, Director of Neurology, Fortis Escorts Hospital, said that a stroke occurs when blood flow to the brain is cut off due to a blocked blood vessel in the brain or rupture of blood vessels in the brain, which is called hemorrhagic stroke.

According to the World Health Organization, stroke is the second leading cause of death and the third leading cause of disability. In fact, one in four people are at risk of having a stroke in their lifetime. Therefore, Dr. Bahrani advised making lifestyle changes to prevent stroke, especially in the winter.

Precautions to reduce the risk of stroke, including:

Strokes can be prevented by taking your prescribed medications regularly, which can include blood pressure medications, cholesterol-lowering medications called statins, and medications that prevent blood clots such as aspirin and other blood thinners.

Some medications that help keep blood sugar close to normal help prevent stroke.

Lifestyle changes such as exercise, smoking cessation, and a diet rich in fruits, vegetables, and low-fat dairy products go a long way toward preventing strokes.

It may also help to reduce your salt intake, as recommended by your doctor, to 5 g per day or 1 teaspoon per day.

Movement or activity, even for short periods of 5 to 10 minutes after every hour of inactivity, has health benefits.

Lose weight If you are overweight, it is helpful to limit your alcohol consumption to safe limits.

It is advisable to quit tobacco in all its forms, be it oral, cigarettes or bidirectional.
