Guide To High Cholesterol
High Cholesterol Levels - Definition and Diagnosis
WEIGHT LOSS Cholesterol Is A Type Of Fat
Cholesterol is a substance known as a lipid, a type of fat. Most of the body's supply of cholesterol is produced in the liver, but some is derived from food (eg. eggs and meat). In simple terms, there are two types of cholesterol: a 'good' type called high density lipoprotein (HDL) and a 'bad' type called low density lipoprotein (LDL). Triglyceride is another lipid, closely related to cholesterol, whose levels, like those of HDL and LDL, should also be monitored.
WEIGHT LOSS High Cholesterol Levels
A high level of cholesterol in the blood is a condition known as hypercholesterolemia. This is a form of hyperlipidemia (also known as lipemia, lipidemia, lipoidemia, hyperlipoidemia) which means simply: excess lipids in the bloodstream. The other type of hyperlipidemia, in addition to hypercholesterolemia, is called hypertriglyceridemia which means: excess levels of triglycerides in the blood.
WEIGHT LOSS What Constitutes A High Cholesterol Count?
Cholesterol levels in the blood (serum cholesterol) are most accurately measured by taking a blood sample after the patient has fasted for 12 hours.
WEIGHT LOSS Optimum Serum Cholesterol
For a middle-aged person, the optimal range of total cholesterol is 115-200 mg/dL (3-5.2 mmol/L). If total cholesterol exceeds 200 mg/dL (5.2 mmol/L), the doctor is likely to take a close look at the patient's levels of HDL, LDL and triglycerides, since it is the proportion of LDL-cholesterol to HDL-cholesterol, and triglyceride level which predicts the likelihood of adverse health consequences such as atherosclerosis.
WEIGHT LOSS US Diagnosis Of High Cholesterol
- Desirable: Less than 200 mg/dL
WEIGHT LOSS UK Diagnosis Of High Cholesterol
- Ideal level: less than 5mmol/l.
WEIGHT LOSS High Cholesterol - Health Risk Assessment
Note that the significance of a specific cholesterol count cannot be assessed without taking into account the ratio between good HDL and bad LDL cholesterol, the triglyceride count, and the presence/absence of other cardiovascular risks, such as smoking, diabetes, raised blood pressure (hypertension), and any likelihood of inherited or familial hypercholesterolemia due to a genetic defect. For example, it is possible for a patient to have a high level of "total" cholesterol yet still have a relatively low cardiovascular risk because of low LDL cholesterol, an absence of other lifestyle-risk factors or because their family history is free from coronary disease. On the other hand, hypertriglyceridemia (high levels of triglycerides) has been linked to atherosclerosis, even when cholesterol levels are normal.
WEIGHT LOSS When Are HDL Cholesterol Levels Too High?
In America, HDL is assessed as follows:
- Less than 40 means you're at higher risk
for heart disease.
WEIGHT LOSS When Are LDL Cholesterol Levels Too High?
In America, LDL is assessed as follows:
- Less than 100 mg/dL (Optimal)
WEIGHT LOSS When Are Triglyceride Levels Too High?
In America, tryglyceride levels are assessed as follows:
- Less than 150 mg/dL (Normal)
WEIGHT LOSS Diagnosis Of High Cholesterol
After fasting for 12 hours, during which only water should be consumed, a patient gives a blood sample which is then used to measure the level of cholesterol, LDL-cholesterol, HDL-cholesterol and triglyceride in the bloodstream. Typically cholesterol levels rise during pregnancy and drop significantly during serious illness.
WEIGHT LOSS Evidence Of Vascular Disease
If the cholesterol count is high, the doctor may seek evidence of cardiovascular disease by measuring the pulse, blood pressure, listening to the heart, and other large arteries, monitoring kidney function with a blood test and arranging an electrocardiogram (ECG).
WEIGHT LOSS When to Have Your Cholesterol Count Checked?
Ideally, men aged 35 and older and women aged 45 and older should have their cholesterol measured annually, although this regularity may vary according to your cholesterol level and what other health risk factors you have.
