With summer comes warm weather and swimming. But for some people, simply knowing how to swim may not be enough to keep them safe, according to Daily MedNews..

This is because certain medical conditions significantly increase the risk of drowning, according to a new Canadian study.. The study found that about one in three adults and children over the age of 10 who drowned in Canada between 2007 and 2016 had a chronic illness, Pannochka, an online publication for girls and women aged 14 to 35, reports.. net First on the list were people with coronary heart disease, a common condition, and people with seizures. Women aged 20 to 34 with seizures were 23 times more likely to drown than the general population, researchers say..

“This is one of the risks that we warn people about, one of the risks that we are very, very aware of,” says Dr. Jacqueline French, professor of neurology at New York University School of Medicine in New York and chief medical officer of the Epilepsy Foundation..

This is a risk that a doctor will discuss with someone with a new diagnosis of epilepsy, French said.. For the study, the research team used data from nearly 4,300 drownings from a Canadian database..

Most drownings happen when someone is alone.. Swimming (25%) and boating (24%) resulted in drowning, with 36% occurring in lakes or ponds. About 81% of those who drowned were men. Investigators found that about 63% of drownings occurred in urban areas.

“If you have a heart attack on the ground, if you are walking or sitting quietly, you can call 911, or if your chest hurts while walking, you can stop,” said Dr. Benjamin Levine, professor of internal medicine at Southwestern Medical. in Dallas. “The river is a dangerous place where there is something that makes you lose consciousness or lose the ability to extricate yourself from the situation”.

Coronary artery disease affects about 20 million people in the United States, with the highest incidence in men aged 60 years and over, but the initial stage begins at age 20. Cardiac arrest - the sudden loss of cardiac function - is one of the most common causes of death for a person with this condition..

A person with coronary artery disease, including a previous heart attack, stent placement, or coronary bypass surgery, should be evaluated before embarking on an exercise program, Becker said..

“Due to physician recommendations for people with known heart conditions, swimming is recognized as an excellent means of low-impact, moderate-intensity exercise,” Becker said.. "

According to study co-author Dr.

Cody Dunn, an emergency physician at the University of Calgary, for people with seizure disorders, even taking a bath carries a risk..

“Bathtub drowning is common in people with seizure disorders, as well as most other pre-existing medical conditions,” the study authors write..

French says people with seizure disorders are often advised to take a shower instead of a bath, and they can use a device in the shower that will turn off the water in the event of a fall to prevent drowning in shallow water..
