Understanding your health numbers can feel like deciphering a secret code. These metrics, often presented during routine check-ups, are powerful indicators of your overall well-being. They offer insights into your risk for various diseases and provide a roadmap for making informed lifestyle choices. This guide aims to demystify common health numbers, empowering you to take control of your health journey.
Decoding Key Health Metrics
Let’s break down some of the most important health numbers and what they signify.
Blood Pressure
Blood pressure measures the force of your blood against your artery walls. It’s recorded as two numbers: systolic (the pressure when your heart beats) and diastolic (the pressure when your heart rests between beats), expressed as millimeters of mercury (mmHg).
- Normal: Less than 120/80 mmHg
- Elevated: Systolic between 120-129 mmHg and diastolic less than 80 mmHg
- Stage 1 Hypertension: Systolic between 130-139 mmHg or diastolic between 80-89 mmHg
- Stage 2 Hypertension: Systolic at least 140 mmHg or diastolic at least 90 mmHg
High blood pressure (hypertension) often has no symptoms, earning it the nickname “the silent killer.” Untreated hypertension can lead to serious health problems, including heart disease, stroke, and kidney disease. Lifestyle modifications, such as diet, exercise, and stress management, can often help lower blood pressure.
Regular blood pressure monitoring is crucial, even if you feel fine. Home blood pressure monitors are readily available and can provide valuable insights into your blood pressure trends over time.
Cholesterol
Cholesterol is a waxy substance found in your blood. While your body needs some cholesterol to function properly, high levels can increase your risk of heart disease.
- Total Cholesterol:
- Desirable: Less than 200 mg/dL
- Borderline High: 200-239 mg/dL
- High: 240 mg/dL and above
- LDL Cholesterol (Bad):
- Optimal: Less than 100 mg/dL
- Near Optimal/Above Optimal: 100-129 mg/dL
- Borderline High: 130-159 mg/dL
- High: 160-189 mg/dL
- Very High: 190 mg/dL and above
- HDL Cholesterol (Good):
- Low: Less than 40 mg/dL (for men), less than 50 mg/dL (for women)
- Optimal: 60 mg/dL and above
- Triglycerides:
- Normal: Less than 150 mg/dL
- Borderline High: 150-199 mg/dL
- High: 200-499 mg/dL
- Very High: 500 mg/dL and above
LDL cholesterol contributes to plaque buildup in your arteries, leading to atherosclerosis. HDL cholesterol helps remove LDL cholesterol from your arteries. Triglycerides are another type of fat in your blood; high levels are often associated with obesity, diabetes, and heart disease.
High cholesterol often presents no symptoms. A lipid panel, a blood test that measures your cholesterol levels, is the only way to know your numbers. Consult your doctor to determine the appropriate frequency for cholesterol testing based on your individual risk factors.
Blood Sugar (Glucose)
Blood sugar, or glucose, is your body’s main source of energy. Your blood sugar levels fluctuate throughout the day, depending on when you eat. High blood sugar levels over time can lead to diabetes.
- Fasting Blood Sugar:
- Normal: Less than 100 mg/dL
- Prediabetes: 100-125 mg/dL
- Diabetes: 126 mg/dL or higher
- A1C (Glycated Hemoglobin):
- Normal: Less than 5.7%
- Prediabetes: 5.7-6.4%
- Diabetes: 6.5% or higher
Fasting blood sugar is measured after an overnight fast. The A1C test provides an average of your blood sugar levels over the past 2-3 months. Prediabetes means your blood sugar levels are higher than normal but not high enough to be diagnosed with diabetes. Making lifestyle changes, such as diet and exercise, can often prevent or delay the onset of type 2 diabetes.
Body Mass Index (BMI)
Body Mass Index (BMI) is a calculation that uses your height and weight to estimate your body fat. While it’s not a direct measure of body fat, it’s a useful tool for assessing your weight status.
- Underweight: Less than 18.5
- Normal Weight: 18.5-24.9
- Overweight: 25-29.9
- Obese: 30 or higher
BMI is just one factor to consider when evaluating your health. Muscle mass, age, and ethnicity can also influence your body composition. Consult your doctor for a comprehensive assessment of your weight status.
Waist Circumference
Waist circumference measures the size of your waist. Excess abdominal fat, even in people with a normal BMI, is associated with an increased risk of heart disease, type 2 diabetes, and other health problems.
- Men: Less than 40 inches
- Women: Less than 35 inches
Measure your waist circumference around your bare abdomen, just above your hip bones. Make sure the tape measure is snug but not constricting.
Heart Rate
Your heart rate, also known as your pulse, is the number of times your heart beats per minute. A normal resting heart rate for adults is typically between 60 and 100 bpm.
- Normal Resting Heart Rate: 60-100 bpm
Factors that can affect your heart rate include age, fitness level, stress, and medications. A consistently high resting heart rate may indicate an underlying health problem.
Kidney Function (GFR)
Glomerular filtration rate (GFR) measures how well your kidneys are filtering waste from your blood. It is a key indicator of kidney function.
- Normal GFR: Typically 90 or above (ml/min/1.73 m2)
A lower GFR indicates that your kidneys may not be functioning as well as they should. Chronic kidney disease (CKD) is often diagnosed based on a GFR below 60 for three months or longer.
GFR is usually estimated from a blood test that measures creatinine levels. Other factors, such as age, sex, and race, are also considered in the calculation.
Liver Function Tests (LFTs)
Liver function tests (LFTs) are a group of blood tests that help assess the health of your liver. They measure the levels of certain enzymes and proteins in your blood.
- Common LFTs include: ALT, AST, Alkaline Phosphatase, Bilirubin, Albumin
Abnormal LFT results can indicate liver damage, inflammation, or disease. Elevated levels of liver enzymes, such as ALT and AST, may suggest liver cell injury.
