Know your numbers: A simple step toward better health

Many common conditions, including high blood pressure, high cholesterol, diabetes, and heart disease, can develop silently without noticeable symptoms. That's why one of the most important things you can do for your health is to know your numbers. 

“Knowing your numbers” (e.g., blood pressure, cholesterol, blood sugar, Body Mass Index (BMI), etc.) is one of the most powerful—and actionable—foundations of preventive care and chronic condition management.  

"It is one of the simplest ways to take control of your health," said Darryel Wilson, MD, Piedmont Physicians at Brown Bridge in Covington. "When you understand where you stand, you and your healthcare provider can work together to reduce your risk for serious health problems down the road." 

Numbers you should know 

• Blood pressure – Key indicator of heart health and stroke risk.  
  Aim for blood pressure below 140/90, with systolic (top number) under 140 and diastolic (bottom number) under 90.
• Cholesterol (LDL, HDL, Total) – Helps assess risk for heart disease.  
  Aim for an LDL (bad) cholesterol of less than 130.  
• Blood sugar (Glucose/A1C) – Essential for detecting and managing diabetes.  
  The Centers for Disease Control and Prevention (CDC) says blood sugar should be 80 to 130 mg/dL before meals. It should stay below 180 mg/dL two hours after meals.  
• Body mass index (BMI) or weight trends – Signals risk for multiple chronic conditions. 
  Calculate your BMI using the National Institutes of Health (NIH) Calculator. The CDC considers a BMI of 18.5 to 24.9 healthy, 25 to 29.9 overweight, and 30 or higher obese.

Targets may vary depending on your individual risk and health history. Talk to your provider about what your numbers mean.  

Why knowing your numbers matter 

Knowing your numbers enables early detection and preventive action. It supports chronic care, accountability, measurable progress, risk reduction, and stronger provider partnerships. 

These numbers can reveal health concerns before symptoms appear. Early awareness allows lifestyle changes or medication when most effective. Dr. Wilson suggests the following heart-healthy lifestyle changes: 

• Avoid tobacco products. Do not smoke. Eat a healthy diet with lean proteins, plenty of fruits and vegetables, and healthy fats. 
• Stay physically active. 
• Manage stress. 
• Get 7-9 hours of sleep every day. 

Schedule your wellness visit 

A primary care provider can help you understand your numbers and track changes over time. They can also create a plan to help you stay healthy. Regular checkups provide the information needed to manage blood pressure, improve cholesterol, and help prevent diabetes.

An annual wellness visit and simple screenings help you know your numbers, understand your risks, and take steps toward better health.
