Urinary tract infections - which plague millions of Britons - are three times more likely to cause a stroke within 30 days of infection, the researchers say

Urgency infections & # 39; TREBLE your risk of having a stroke in the next 30 days & # 39 ;, find study

  • UTI is three times more likely to cause ischemic stroke, the most common type
  • Ischemic stroke occurs when blood clots block blood flow and oxygen to the brain
  • Researchers say that UTI ensures that blood vessels clog up and have difficulty transporting blood

Urinary tract infections (UTI & # 39; s) can increase your chances of having a stroke, a study has warned.

Scientists have discovered that patients with UTIs are three times more likely to have a cerebral infarction within 30 days of catching the bug.

Ischemic strokes occur when a blood clot blocks blood flow and the supply of oxygen to the brain, the NHS says. They are the most common type of stroke.

Various other infections were found to increase the risk of stroke, including blood poisoning, abdominal, skin and respiratory problems.

The researchers looked from 2006 to 2013 at all visits from hospitals and emergency care to hospitals in the state of New York.

They compared patient records to see if they had infections in the four months prior to suffering a stroke.

For all infections, the risk of stroke was higher within 30 days after infection, the team of academics discovered.

Dr. Mandip Dhamoon, senior study author, said: “Healthcare providers should be aware that a stroke can be caused by infections.

& # 39; Investigation into the preceding weeks or months of a patient's life before the stroke can sometimes help alleviate the possible causes of a stroke if there was an infection during that period.


& # 39; Our research shows that we need to do more to understand why and how infections are associated with the occurrence of different types of strokes, and that will help us determine what we can do to prevent these types of strokes.

& # 39; These findings suggest that there may be implications for vaccination, antibiotic regimens or intensive antithrombotic treatments, not only to prevent infections, but to prevent stroke in people who are considered risky. & # 39;

Compounds were also investigated with two other types of stroke – intracerebral bleeding caused by ruptured blood vessels in the brain, and subarachnoid bleeding, an unusual type that results from bleeding on the inner lining of the brain.

For intracerebral, the strongest association with prevention was for UTI, blood poisoning and respiratory infections.

Breathing was the only infection associated with subarachnoid hemorrhage.


UTI & # 39; s arise when bacteria urinate the kidneys, the kidneys, the bladder and the tubes that run between them.

Symptoms include frequent urge to urinate, pain while urinating, and abdominal discomfort.

Women are up to 30 times more likely to suffer than men because their urethra – the tube through which urine leaves the body – is shorter than that of a man and closer to the rear passage.

More than half of women have at least one UTI during their lifetime, and a third of them have three or more episodes per year.

The findings were published in the Journal of The American Heart Association.



The best way to help prevent a stroke is by eating healthily, exercising regularly and smoking too much and drinking too much alcohol.

These lifestyle changes can reduce your risk of problems such as:

  • arteries become clogged with fatty substances (atherosclerosis)
  • high bloodpressure
  • high cholesterol


An unhealthy diet can increase your chances of having a stroke, as this can lead to an increase in your blood pressure and cholesterol levels.

A low-fat, high-fiber diet is usually recommended, including lots of fresh fruit and vegetables (5 A day) and whole grain.


You should limit the amount of salt you eat to no more than 6 g (0.2 oz) per day because too much salt raises your blood pressure: 6 g of salt is about 1 teaspoon.


For most people it is recommended to do at least 150 minutes (2 hours and 30 minutes) of moderate intensity aerobic activities, such as cycling or speed walking, every week.

Stop smoking

Smoking significantly increases the risk of stroke. This is because it narrows your veins and causes your blood to clot faster.

Reduce alcohol

Excessive alcohol consumption can lead to high blood pressure and cause an irregular heartbeat (atrial fibrillation), both of which can increase the risk of stroke.

Heavy drinking multiplies the risk of stroke by more than 3 times
