February marks Heart Month in many countries, highlighting the importance of heart health. In London, Dr. Elijah Behr, a cardiologist at Mayo Clinic Healthcare, provides insights into fainting and its potential link to serious conditions.
Fainting, or syncope, is a temporary loss of consciousness caused by reduced blood flow to the brain. Dr. Behr describes vasovagal syncope as the most benign form of fainting. "In some people," he explains, "if they have a drop in blood pressure from emotional distress, pain, illness or dehydration... it starts to slow down."
Typically, this type of fainting resolves when the person falls and blood returns to the brain. However, Dr. Behr warns that fainting can be dangerous if it occurs in vulnerable situations.
Cardiac syncope is more concerning for healthcare professionals. It involves blackouts due to underlying heart diseases such as arrhythmias. "This is usually a more abrupt loss and return of consciousness than in simple fainting," Dr. Behr notes.
Individuals with family histories of heart problems or unexplained deaths should be vigilant about blackouts related to exercise or accompanied by palpitations. Symptoms may include lightheadedness, nausea, buzzing in the ears, and tunnel vision.
"If your blood pressure is getting low," advises Dr. Behr, "get your head level or below your heart." He cautions against standing immediately after fainting as it may lead to further complications.
Drinking water with electrolytes and adding salt to one's diet can help prevent future episodes. For persistent cases, medication might be necessary.
"If somebody has had simple fainting... it's best not to ignore it," says Dr. Behr. Visiting a GP or emergency department after a first episode is encouraged.
Older individuals experiencing recurrent faints should seek medical attention promptly due to possible underlying conditions.
Differentiating between seizures and faints requires professional assessment from both cardiologists and neurologists.
"It's very common," concludes Dr. Behr regarding fainting episodes but emphasizes that cognitive behavioral therapy (CBT) could assist those affected by negative thinking patterns related to their condition.
