Blood pressure
If your blood pressure were high, wouldn't you know it? "Unfortunately, more frequently there are no symptoms—that's the issue," says Christie Ballantyne, M.D., a cardiologist and professor of medicine at Baylor College of Medicine in Houston. High blood pressure, also called hypertension, can lead to heart attack, stroke and kidney disease. "We could prevent 80 percent of problems caused by high blood pressure if people would get checked and take the proper steps," Dr. Ballantyne says.
For the average healthy adult, these are the numbers to go by:
- Optimal blood pressure: Less than 120/80
- Pre-hypertension: 120-139/80-89
- High blood pressure: 140/90
High blood pressure controlled with medication should be less than 140/90. If you have diabetes, it should be less than 130/80. Learn more Facts about Hypertension
Cholesterol
Many of us know our total cholesterol, but not our lipid profiles. That's a fancy name for the types of fats in the blood. "What a lot of people believe is that if they're being treated with medication for high cholesterol, they're cured," says internist H. Timothy Dombrowski, D.O., an associate professor of medicine at the University of Medicine and Dentistry of New Jersey-School of Osteopathic Medicine. "They don't realize that if they stop their medication, their lipid issue will resurface."
For adults without chronic disease or major risk factors for heart disease, these are the recommended levels for total cholesterol and the various forms that cholesterol takes in the blood:
Optimal total cholesterol: less than 200
LDL ("bad") cholesterol:- Optimal: less than 160
- Cause for concern: more than 160
- Men: more than 45
- Women: more than 50
- Desirable: less than 150
- Borderline: 150-199
- Problem: 200 or more
- Serious problem: 500

Blood sugar
High blood sugar or diabetes can lead to other ailments. Among them are high blood pressure, kidney disease, visual problems, heart disease, and stroke.The following are the important numbers for blood sugar.
Blood sugar (after an eight-hour fast):- Optimal: less than 100
- Pre-diabetes: 100-125 (at risk for diabetes; change lifestyle)
- Diabetes: 126 or higher
"If we catch this earlier, diet and exercise can prevent progression into diabetes," Dr. Dombrowski says. "The message here is to prevent progression when you're pre-diabetic. Don't blow it off."
If you have diabetes, you'll have A1C tests from time to time. These measure your average blood sugar levels over the past two or three months to see how treatment is working. The A1C goal, set by the American Diabetes Association, is 7 percent or less; 6 percent or less is even better.
