How a PCP Can Help Detect Common Health Issues in Young Adults

Chronic health conditions don’t always wait till later in life to appear. Many begin in young adulthood — often without clear or noticeable symptoms — which is why having a trusted primary care provider to support your whole health matters.

According to the Centers for Disease Control and Prevention (CDC), more than half of adults ages 18 to 34 in the U.S. are already living with at least one chronic health condition, a reminder of the importance of early care and prevention.

What are some of the most common health issues in young adults, and how can primary care services help? Learn what to look for and why catching concerns early can make a meaningful difference in your long-term health, from your 20s to the decades beyond.

How Common Are Chronic Conditions in Young Adults?

The CDC reports that up to 23% of all young adults in the country have more than one chronic condition, including health issues like obesity, depression and high blood pressure.

In a 2025 CDC study, the number of young people with one or more chronic health conditions rose from about 52% to 59%. This means that your friends, family or coworkers may be dealing with health issues that they might not even be aware of. Scheduling a visit with your primary care provider can help you navigate any health issues you may be experiencing.

The Most Common Health Issues in Young Adults (and Why They Matter)

There are a few common health conditions young adults should be aware of, all of which can be detected early with regular primary care visits.

1. Obesity and Metabolic Risk

   According to the CDC, about 25.5% of adults aged 18 to 34 years old suffer from obesity. This is concerning because obesity is associated with a higher risk of heart disease and diabetes, among other conditions.

   It’s common to think, “I’ll deal with this health issue later,” but changes that start in your 20s and 30s can already be affecting your health. Early guidance from a primary care provider (PCP) can help you make realistic, sustainable changes.

2. Elevated Cholesterol and Other Metabolic Markers

   In 2023, the CDC reported that elevated cholesterol was among the most reported chronic health issues in young adults. Over time, elevated cholesterol can contribute to plaque buildup in the arteries, increasing the risk of heart disease.

   A PCP can identify these issues during an annual wellness visit by performing a lipid panel via blood draw. Knowing your cholesterol levels allows you to start making lifestyle changes, or if necessary, begin taking medications.

3. High Blood Pressure (Hypertension/Elevated BP)

   High blood pressure doesn’t always cause noticeable symptoms, which is why it’s often called a “silent” condition. In 2019, about 10.7% of young adults reported high blood pressure, and that number continues to rise.

   Even mildly elevated blood pressure can strain your heart, blood vessels and kidneys over time. Regular checkups allow your PCP to spot changes in your blood pressure early and help you protect your long-term health.

4. Mental Health

   Another of the most common chronic diseases in young adults is depression. In 2019, the CDC reported that 21.3% of young adults reported experiencing depression. In 2023, a significant number of studies show that this remains a top issue for young adults.

   Depression and anxiety can affect sleep, energy, appetite and stress levels. And your mental health can have an impact on physical health as well. Primary care visits create space to talk openly with your PCP about mood, stress and emotional well-being, and to help you get connected with additional support when needed.

5. Asthma, Respiratory Issues and Other Long-Term Conditions

   Respiratory issues are not as common as metabolic issues in young adults, but asthma and asthma-related symptoms are still problematic. Chronic respiratory issues can impact quality of life and productivity. Without treatment, they can get worse as time passes.

   A PCP can help identify triggers, manage symptoms and prevent flare-ups before they interfere with your quality of life.

6. The “Hidden Danger” of Multiple Conditions (Comorbidity/Multimorbidity)

   In 2019, about 22% of young adults were living with two or more chronic conditions. When conditions overlap, they can increase the risk of more serious health problems down the road.

   Primary care providers look at the bigger picture, not just isolated symptoms, which helps them recognize patterns and address concerns early. Schedule your annual wellness visit at AdventHealth Primary Care+ today.

Why Young Adults Sometimes Skip Care and What That Costs Them

A PCP is your first point of contact for preventive care, health screenings and everyday health concerns. Still, many young adults skip regular checkups, often because they feel healthy or assume problems can wait.

The challenge is that many chronic conditions don’t cause obvious symptoms at first. By the time signs appear, they may be harder to manage. Seeing your PCP regularly helps catch concerns early, when they’re often easier to treat. Early detection also helps prevent future complications from untreated illnesses.

Practical Tips for Young Adults

One of the first things to keep in mind is how often you should see your PCP. Schedule a yearly wellness visit, or more often if you have chronic conditions.

Other tips to prevent chronic conditions or manage them if caught early include:

• Focus on healthy, daily habits like balanced nutrition, regular movement, adequate sleep and stress management
• Avoid smoking and limit alcohol
• Pay attention to family history and other risk factors
• Check cholesterol and blood pressure regularly, even if you feel fine
• Speak up if you’re feeling overwhelmed, anxious or low

Keeping track of this information, even in a simple note or app, can help you and your PCP work together more effectively.

Your Health Is Worth It, Especially When You’re Young

When you’re young, life feels long. So, it’s natural to feel like you have plenty of time to address any health concerns. Especially if you feel mostly healthy or like any issues are minor. But many chronic conditions develop slowly, often long before you have any noticeable symptoms. That’s why early detection and consistent care matter so much.

Regular visits with your primary care provider help you protect your health now and set you up for a healthier future.
