Most Common Diagnoses in Primary Care
What a primary care doctor sees most, how it compares with national research, and what you can do besides take a pill. A guide for adults in Shreveport, Bossier City, and Northwest Louisiana.
You have a new diagnosis, or maybe three. You leave the office with a prescription and a follow-up in six months. You wonder if that is all there is. For most people, the most common diagnoses in primary care are high blood pressure, obesity, type 2 diabetes, anxiety, depression, heart disease, arthritis, functional decline in older adults, high cholesterol, and respiratory infections like colds and bronchitis. National research lists nearly the same conditions.[1][2][3] Most of these are long-term problems, and here is the good news: medication is only one of your tools. Time, a clear plan, and a doctor who knows your goals can make a real difference.
What Are the 10 Most Common Diagnoses in Primary Care?
At Shreveport Direct Care, I care for adults and children from birth to the end of life. When I look at what fills my schedule week after week, eight conditions rise to the top. These are anxiety, obesity, high blood pressure, diabetes, depression, heart disease, arthritis, and functional decline in older adults. Functional decline means slowly losing the ability to do everyday things, like climb stairs, drive, cook, or manage medicines.
To round out a top 10, I added two conditions that show up near the top of every national report: high cholesterol and acute respiratory infections. Here is the full list, with the conditions I see most in my own practice first.
High blood pressure (hypertension)
Obesity
Type 2 diabetes
Anxiety
Depression
Heart disease
Arthritis and joint pain
Functional decline in older adults
High cholesterol
Colds, sinus infections, bronchitis, and other respiratory infections
If you want a quick look at the conditions we treat every week, we also wrote a shorter guide to the top 10 conditions a family doctor in Shreveport treats. This article goes deeper. It compares my list with published research and talks about what helps beyond medication.
How My List Compares to Published Reports
You asked a fair question: is my clinic experience typical, or different? I compared my list with three well-known sources.
The first is the National Ambulatory Medical Care Survey (NAMCS), a large federal survey from the CDC. In 2018, Americans made about 860 million visits to doctors’ offices, and about 40% of those visits were to primary care doctors.[1] Leaving out checkups and pregnancy visits, the most common diagnoses were high blood pressure (about 33.6 million visits), type 2 diabetes (about 27 million), osteoarthritis (about 16.7 million), depression (about 13.1 million), colds and other acute respiratory infections (about 13 million), and high cholesterol (about 10 million).[1] One note: this survey counts visits to all office-based doctors, including eye doctors and other specialists, not only primary care.
The second is a 2018 review that pulled together 18 studies of primary care visits.[2] The 10 conditions doctors reported most often were upper respiratory infections, high blood pressure, routine health checkups, arthritis, diabetes, depression or anxiety, pneumonia, ear infections, back pain, and skin rashes (dermatitis).[2]
The third is a Mayo Clinic study of more than 140,000 people in Olmsted County, Minnesota, from 2005 to 2009.[3] It looked at what conditions people were diagnosed with over five years. Skin disorders topped the list, followed by arthritis and joint disorders, back problems, cholesterol problems, upper respiratory conditions, anxiety and depression, chronic nerve disorders, high blood pressure, headaches, and diabetes.[3]
Here is how they line up.
| Condition | Dr. Bass (SDC) | CDC office visit survey, 2018 [1] | 2018 review of 18 studies [2] | Mayo Clinic study [3] |
|---|---|---|---|---|
| High blood pressure | Yes | Yes (#1 disease) | Yes | Yes |
| Diabetes | Yes | Yes | Yes | Yes |
| Arthritis / joint pain | Yes | Yes | Yes | Yes |
| Depression | Yes | Yes | Yes | Yes |
| Anxiety | Yes | Partly (grouped with mood disorders) | Yes | Yes |
| High cholesterol | Added | Yes | No | Yes |
| Respiratory infections | Added | Yes | Yes | Yes |
| Heart disease | Yes | Yes (coronary disease, lower on list) | No | No |
| Obesity | Yes | Not in top 20 | No | No |
| Functional decline | Yes | No | No | No |
| Back pain | Not in top 10 | Yes | Yes | Yes |
| Skin problems | Not in top 10 | Yes | Yes | Yes (#1) |
So what does that tell us? The core is the same everywhere. High blood pressure, diabetes, arthritis, depression, and anxiety show up on every list, including mine.
The differences are interesting, and they make sense. Obesity rarely shows up in these reports because it is often not written down as the main reason for a visit. A doctor may record the blood pressure or the diabetes instead, even when weight is part of what drives both. I list it because I treat it directly. Functional decline also does not appear on these lists, partly because it is not one diagnosis. It is a pattern made up of weakness, falls, memory changes, and loss of independence. Because I care for older patients, including at home, I see it a lot. Skin problems, back pain, and colds are near the top of the national lists. I see them too. They just tend to be quick, one-time problems in my practice, while my schedule is filled with the long-term conditions that need more time.
The 10 Conditions, One by One
Below is a short look at each condition: what it is, how it compares to national data, and what can help besides medication. Medication is a tool, and often an important one. It is just not the only one.
1. High Blood Pressure
High blood pressure is the most common disease diagnosis in the CDC’s office visit survey, with about 33.6 million visits in one year.[1] It usually causes no symptoms, which is why so many people do not know they have it. Over time, it strains the heart, brain, kidneys, and eyes.
National guidelines list several proven non-drug steps that lower blood pressure: losing extra weight, eating more fruits and vegetables, cutting back on salt, moving more, and limiting alcohol.[10] For some people, these steps are enough. For others, they help medication work better at a lower dose. You can read more about why high blood pressure is worse in Louisiana men and whether weight loss can lower blood pressure.
2. Obesity
Obesity is a chronic disease, not a lack of willpower. It raises the risk of diabetes, high blood pressure, sleep apnea, joint pain, and heart disease. In 2024, 39.2% of Louisiana adults had obesity, the third-highest rate in the country.[4]
What helps is a plan built around your body and your life. That may include changes to when and what you eat, strength training to protect muscle, better sleep, and, for some people, medication such as a GLP-1. We focus on metabolic health, not just the number on the scale. Learn more about our physician-led weight loss program.
3. Type 2 Diabetes
Type 2 diabetes is the second most common disease diagnosis in the CDC survey.[1] In Louisiana, 15.4% of adults have been told they have diabetes, which ranks 47th among states.[5]
Here is one of the strongest findings in all of primary care. In a large national study called the Diabetes Prevention Program, people with prediabetes who lost 5% to 7% of their body weight and walked about 30 minutes a day, five days a week, cut their risk of getting diabetes by 58%.[7] For people who already have diabetes, food choices, meal timing, and activity can often improve blood sugar along with medication. We explain the science behind meal timing in why intermittent fasting works. We actually can help you lose weight, deprescribe and get off medications for both diabetes and high blood pressure.
4. Anxiety
Anxiety is one of the most common things I treat, and the Mayo Clinic study grouped it with depression in its top 10.[3] It can show up as worry that will not turn off, trouble sleeping, a racing heart, stomach problems, or feeling on edge.
Anxiety often has a story behind it: stress at work, caring for a parent, money worries, poor sleep, or too much caffeine. When I have time to hear that story, we can work on the causes, not just the symptoms. Therapy, regular exercise, better sleep, and sometimes medication all have a place.
5. Depression
Depression appears on every list I reviewed.[1][2][3] It is more than feeling sad. It can drain energy, sleep, appetite, focus, and joy.
Exercise is real medicine for depression. A 2024 review in The BMJ looked at many clinical trials and found that walking, jogging, yoga, and strength training all helped reduce depression, and that structured programs worked best.[8] Exercise does not replace therapy or medication when those are needed. It works alongside them. If you ever feel hopeless or have thoughts of hurting yourself, please call or text 988 right away.
6. Heart Disease
Heart disease is the leading cause of death in the United States.[11] It often grows quietly for years, driven by high blood pressure, diabetes, high cholesterol, smoking, and inactivity.
That is why so many conditions on this list connect. When we improve blood pressure, blood sugar, and weight, we also lower heart risk. For some patients, a test like a coronary calcium score helps us see how much plaque is already there and how hard to push on prevention.
7. Arthritis and Joint Pain
Osteoarthritis was the third most common disease diagnosis in the CDC survey, and joint problems appeared on every published list.[1][2][3] Knees, hips, hands, and backs wear down over time, especially with extra weight.
The American College of Rheumatology strongly recommends exercise for knee, hip, and hand arthritis, along with weight loss for people with extra weight.[9] It sounds backwards to move more when your joints hurt, but the right kind of movement often eases pain and keeps you active. Pain medicine, physical therapy, and sometimes injections can help too.
8. Functional Decline in Older Adults
This one is not on the national lists, but it is on mine. Functional decline is the slow loss of strength, balance, memory, or energy that makes daily life harder. It can look like a parent who stops cooking, misses bills, or falls. About 1 in 4 adults age 65 and older report a fall each year.[12]
Much of this can be slowed when we catch it early. Strength and balance work, a review of medicines that cause dizziness, vision and hearing checks, and home safety changes all help. Families can learn more about preventing falls and what it means when everyday tasks become a struggle.
9. High Cholesterol
High cholesterol shows up in the CDC survey and the Mayo study.[1][3] Like high blood pressure, it causes no symptoms. It quietly builds plaque in the arteries.
Diet, exercise, and weight loss can lower cholesterol for many people. For people at higher risk of heart attack or stroke, a statin is often a good choice. The right answer depends on your overall risk, which is something we talk through together.
10. Colds, Sinus Infections, and Bronchitis
Upper respiratory infections topped the 2018 review of 18 studies and appear in the CDC survey.[1][2] Most are caused by viruses, so antibiotics do not help. Rest, fluids, and time usually do.
What patients need most here is access: a quick text or call to know whether this is a cold or something more serious. That simple step can save a trip to urgent care.
The Biggest Myth: “Medication Is All I Can Do”
The most common thing I hear from new patients is some version of this: “My doctor gave me a pill. I guess that is all I can do.” It is not true, and it is not their fault. In a rushed visit, there is only time to adjust a prescription. There is no time to talk about the rest.
I want to be clear. Medication is a good tool. Many of my patients need it, and I prescribe it. But for most of the conditions on this list, what you eat, how you move, how you sleep, and how you handle stress matter a lot too. The research above backs that up.
Most Common Chronic Diseases
Example of How This Works at Shreveport Direct Care
The following is an illustrative example, a composite of patterns we often see.
Imagine Denise, a 54-year-old office manager from Bossier City. She has high blood pressure, prediabetes, 40 extra pounds, and a lot of worry. She takes two blood pressure pills and thinks that is simply her life now.
At her first visit, we do not start with her numbers. We start with her. What does she want? She says she wants to keep up with her grandkids at the park and not end up like her mother, who had a stroke at 62. Now we have a goal that matters to her.
We learn she skips breakfast, snacks all afternoon, sleeps five hours a night, and has not exercised since her kids were small. We make a plan she believes she can do: regular meals, an evening walk with a neighbor, and a bedtime alarm. She texts me her home blood pressure readings each week. Over several months, she loses weight, sleeps better, and feels calmer. Her blood pressure improves enough that we are able to lower one of her medicines. Not every patient will see results like this, but many see real progress when the plan fits their life.
Why These Diagnoses Hit Harder in Shreveport and Northwest Louisiana
These conditions are common everywhere, but they are more common here. Louisiana ranks among the worst states for obesity, diabetes, and high blood pressure. About 43% of Louisiana adults have been told they have high blood pressure, compared with 34% nationally.[6] Obesity affects 39.2% of adults, and diabetes affects 15.4%.[4][5]
These conditions feed each other. Extra weight raises blood pressure and blood sugar. High blood pressure and diabetes raise heart risk. Pain makes it harder to stay active. Worry and low mood make it harder to stick with any plan. For families in Shreveport, Bossier City, and across the Ark-La-Tex, that means many adults are managing several of these conditions at once.
That is exactly why time matters. A 9-minute visit can refill a prescription. It cannot untangle four connected problems. Read more about why the 15-minute office visit is failing patients.
How Primary Care in Shreveport Can Look Different
At Shreveport Direct Care, I spend a lot of time talking with patients. I want to know your goals and how you see your own health before we make a plan. That conversation is often where the real answers are.
Our membership model makes that possible. For a flat monthly rate, you get longer visits, same-day or next-day appointments, and the ability to call or text me directly. That access lets us adjust your plan in real time instead of waiting months between visits. It is what comprehensive primary care is supposed to look like.

FAQs:
1. What is the most common diagnosis in primary care?
High blood pressure is the most common disease diagnosis at U.S. doctor office visits, with about 33.6 million visits in 2018. Routine checkups are even more common, but they are not a disease.
2. What are the most common chronic diseases?
High blood pressure, type 2 diabetes, obesity, high cholesterol, heart disease, arthritis, depression, and anxiety are among the most common long-term conditions treated in primary care.
3. Can these conditions be managed without medication?
Sometimes, and lifestyle changes help in almost every case. Diet, exercise, weight loss, sleep, and stress care can improve many of these conditions. Many people still need medication, and that is okay. Talk with your doctor before stopping any medicine.
4. Why are these conditions so common in Northwest Louisiana?
Louisiana has some of the highest rates of obesity, diabetes, and high blood pressure in the country. These conditions are linked, so having one raises the risk of the others.
5. Should I see a primary care doctor or a specialist for these conditions?
Most of these conditions can be managed well by a primary care doctor. A primary care doctor can also see how your conditions connect and refer you to a specialist when you truly need one.
6. How can a primary care doctor in Shreveport help me manage several conditions at once?
It takes time. At Shreveport Direct Care, longer visits and direct text access let us build one plan for all of your conditions, track your progress, and adjust between visits.
