Heart disease is often seen as a problem that only affects older adults, but more and more young people are being diagnosed with heart conditions.
In fact, research shows that heart disease is becoming more common in people under the age of 40.
This shift has raised concerns among doctors and researchers, who are now working to understand what’s behind the rise and how to prevent it.
Many of the causes are linked to lifestyle, but some people may also have genetic risks or underlying medical conditions.
One of the biggest causes of heart disease in young adults is poor diet. Many people eat foods that are high in sugar, salt, and unhealthy fats.
These eating habits can lead to obesity, high blood pressure, and high cholesterol—all of which increase the risk of heart disease. Fast food, sugary drinks, and processed snacks are especially harmful when consumed regularly over time.
Lack of physical activity is another major factor. Exercise helps keep the heart strong and supports good circulation. When people don’t move enough, it increases the chance of gaining weight and developing other risk factors like diabetes and high blood pressure.
The American Heart Association recommends at least 150 minutes of moderate exercise each week, but many young adults don’t meet this goal.
Smoking and vaping are also dangerous habits linked to heart disease. Smoking damages the blood vessels and reduces oxygen in the blood, making the heart work harder.
Even vaping, which is often marketed as safer than smoking, can harm the heart and lungs. Studies have shown that nicotine and other chemicals in e-cigarettes can raise blood pressure and cause inflammation in the blood vessels.
Stress is another surprising factor. Many young adults deal with financial worries, job pressure, relationship problems, and academic stress. Chronic stress increases levels of hormones like cortisol, which can raise blood pressure and contribute to heart problems over time. Poor sleep and unhealthy coping habits like drinking or overeating can make things worse.
Some causes of heart disease in young people are related to medical conditions. Diabetes, for example, increases the risk of heart disease, especially if it is poorly managed. High blood pressure, even when it shows no symptoms, can slowly damage the arteries.
Some people may also have inherited conditions like familial hypercholesterolemia, which causes very high cholesterol levels from a young age.
Drug and alcohol use can also play a role. Cocaine and other stimulants can cause sudden heart attacks, even in healthy young people. Heavy alcohol use can weaken the heart muscle and lead to irregular heart rhythms.
Recent studies also suggest that COVID-19 may increase the risk of heart inflammation and other cardiovascular problems in some young people, even after recovery. This is still being researched, but it adds another layer of concern.
The good news is that most cases of heart disease in young adults can be prevented. Healthy eating, regular exercise, not smoking, managing stress, and getting regular checkups can all reduce risk.
If you have a family history of heart disease or other risk factors, it’s important to talk to your doctor and get tested early. Taking care of your heart now can protect your health for decades to come.
