Know your heart Numbers
We're talking the big three -- cholesterol, blood pressure, and blood sugar -- plus, two more you should probably know: homocysteine and C-reactive protein. Consider these numbers a stock ticker for your ticker. They tell you how you're doing, and when you need to do more. When you have them measured, make sure your doctor also tells you what your goal levels should be and what you can do to get there. Getting more active, losing weight, and making smart food choices can help get these numbers in a healthy range.
Cholesterol is a fatty, waxy substance found in foods, and produced by our liver. It is used to protect nerves, construct cell tissues, and make certain hormones. Cholesterol is a very important substance, and is needed in small quantities for the body to function correctly. In high quantities, however, it can have an adverse effect on our health.
Your cholesterol level is measured in milligrams per deciliter of blood (mg/dL) - there three measures - one for HDL cholesterol, which is the 'good' kind of cholesterol, one for LDL cholesterol, which is the 'bad' kind, and one for your triglyceride level. Your optimal cholesterol levels will vary depending on your height, weight, gender, age, blood pressure, and a number of other hereditary and lifestyle factors - including whether or not you smoke.
Blood Pressure :
The following classification of blood pressure applies to adults aged 18 and older. It is based on the average of seated BP readings that were properly measured during 2 or more office visits.
Note : These Numbers are considered to be on an average basis of the world population and can vary vastly depending on your location, age, sex and many other factors. Please consult your doctors to be exact on your blood pressure advice.
Classification of blood pressure for adults
S=systolic, D= diastolic, all units in mmHg
Hypotension S < 90 and D< 60
Normal S= 90 – 120 and D= 60 – 80
Prehypertension S =121 – 139 or D= 81 – 89
Stage 1 Hypertension S= 140 – 159 or D= 90 – 99
Stage 2 Hypertension S ≥ 160 or D ≥ 100
Blood sugar: Normal glucose levels fall between 70 and 150 mg. Levels typically are lower in the morning, and rise after meals. Blood sugar levels falling consistently above 150 are indicative of hyperglycemia, or high blood sugar. Chronic low levels, falling below 70, characterize hypoglycemia, or low blood sugar.
