How can asthma cause a stroke?
Asthma is a chronic inflammatory disease that causes the airways to become swollen and narrow. According to Dr. Kadam Nagpal, Head of Neur Immunology at Salubritas Medical Center (New Delhi, India), this prolonged inflammation is not only limited to the lungs but can also affect blood vessels, making them vulnerable and forming blood clots - the leading cause of stroke.
Some drugs that treat asthma such as corticosteroids can increase blood pressure, retain water and cause metabolic disorders, thereby increasing the risk of stroke, adds Dr Vikas Mittal.
The effects of asthma on the heart and brain
Asthma is not just a simple difficulty breathing, but can also create a burden on the cardiovascular system through the following mechanisms:
Lack of oxygen: Severe asthma can reduce the amount of oxygen delivered to the organs, causing the heart to work harder and increasing pressure on the brain.
Inflammation and vascular damage: Chronic inflammation can damage the lining of blood vessels, creating conditions for plaque and atherosclerosis - the leading risk factor for stroke.
Stress hormones: When you have a stroke, your body secretes stress hormones like adrenaline and cortisol, causing your heart rate and blood pressure to increase increasing the risk of stroke.
How to reduce the risk of stroke if you have asthma
Control inflammation properly: Comply with asthma treatment, use anti-inflammatory drugs as prescribed.
Keep your blood pressure stable: Limit salty foods, avoid processed foods, and monitor your blood pressure regularly.
Exercise moderately: Choose light exercises such as walking, swimming - avoid activities that trigger a breathing spell.
Don't smoke and limit exposure to polluted environments: These are two factors that aggravate both asthma and blood vessel problems.
Regular health check-ups: Monitor your respiratory and cardiovascular performance and talk to your doctor to adjust your treatment regimen as needed.
Note
Dr. Vikas Mittal emphasizes that asthma not only affects the lungs but can also harm the heart and brain if not treated properly. Controlling your illness, living healthy and checking your health regularly will help you not only breathe easily but also protect your heart and brain health.
