A person is considered at high risk for developing heart disease if their total cholesterol level is higher than 240 mg/dL, LDL levels are higher than 160 mg/dL (190 mg/dL is even higher risk), and if the HDL level is below 40 mg/dL.
Blood cholesterol is measured in units called millimoles per litre of blood, often shortened to mmol/L. As a general guide, total cholesterol levels should be: 5mmol/L or less for healthy adults. 4mmol/L or less for those at high risk.
Types of Cholesterol
Levels of LDL cholesterol higher than 130 milligrams per deciliter (mg/dL) are linked to an increased risk for ischemic stroke.
If a person's reading is 130–159 mg/dl, it is borderline high, while readings of 160–189 mg/dl are high. A reading of at least 190 mg/dl is very high.
As a guide, health authorities recommend cholesterol levels should be no higher than 5.5 mmol per litre if there are no other risk factors present, or LDL levels less than 2 mmol/l for those who smoke, have high blood pressure or pre-existing heart disease.
Research shows lowering cholesterol can lower the risk of another stroke by about 20%. National Stroke Guidelines strongly recommend taking medication to lower LDL cholesterol to under 1.8 mmol/L (70 mg/dL). - Recommended for patients after stroke caused by a blood clot.
A cholesterol level of 6.5 mmol/L is considered very high.
Your doctor will also look at ratios of your good and bad cholesterol and whether you have any risk factors of heart disease. Cholesterol is a fat produced by the cells in the body and obtained from animal-based foods.
Your health care team may prescribe medicine if: You have already had a heart attack or stroke or have peripheral arterial disease. Your LDL cholesterol level is 190 mg/dL or higher. You are 40–75 years old and have diabetes and an LDL cholesterol level of 70 mg/dL or higher.
Soluble fiber can reduce the absorption of cholesterol into your bloodstream. Soluble fiber is found in such foods as oatmeal, kidney beans, Brussels sprouts, apples and pears. Add whey protein. Whey protein, which is found in dairy products, may account for many of the health benefits attributed to dairy.
Chronic stress leads to consistently high levels of stress hormones, which in turn can lead to consistently high blood pressure, blood sugar, cholesterol, and/or triglycerides.
The lowdown. High cholesterol does not directly cause fatigue. Fatigue is often associated with the complications of high cholesterol, but high cholesterol does not typically cause symptoms. High cholesterol can lead to coronary artery disease, peripheral artery disease, or stroke if left untreated.
Some behaviors or conditions can cause sudden increases in blood cholesterol. This includes high coffee intake, rapid weight loss, cigarette smoking, and psychological stress. Being pregnant and taking certain medications, such as antihypertensive drugs, can also quickly increase cholesterol.
High cholesterol has no symptoms. A blood test is the only way to detect if you have it.
Low-density lipoprotein (LDL) cholesterol.
The most important thing your doctor will keep in mind when thinking about statin treatment is your long-term risk of a heart attack or stroke. If your risk is very low, you probably won't need a statin, unless your LDL is above 190 mg/dL (4.92 mmol/L).
When people have high cholesterol their LDL (bad) is high and their HDL (good) is low. Eating healthy, regular exercise and drinking plenty of water will help to bring down cholesterol levels within 2-3 weeks.
Tisch Center for Women's Health at the NYU Langone Medical Center, says it can take between three to six months to see lower LDL numbers through just diet and exercise, noting that it takes longer to see changes in women than men.
While coffee does not contain cholesterol, it can affect cholesterol levels. The diterpenes in coffee suppress the body's production of substances involved in cholesterol breakdown, causing cholesterol to increase. Specifically, coffee diterpenes may cause an increase in total cholesterol and LDL levels.
If you're taking a statin medication to lower your cholesterol, you will need to keep taking your prescription, or your cholesterol will likely go back up. Stopping your statin can put you at risk of having heart disease and other preventable health problems like stroke and heart attack from high cholesterol.
People who have had a heart attack or stroke will be advised to take a statin to help reduce the risk of them having another event. You'll also be advised to take a statin if you're considered to be at significant risk of developing cardiovascular disease, or of having a heart attack or stroke.
TC:HDL ratio
Above 6 is considered high risk - the lower this figure is the better. Above 6 is considered high risk - the lower this figure is the better.
According to Michos, an ideal LDL cholesterol level should be less than 70 mg/dl, and a woman's HDL cholesterol level ideally should be close to 50 mg/dl. Triglycerides should be less than 150 mg/dl. As Michos notes, total cholesterol levels well below 200 mg/dl are best.
High cholesterol means having a total cholesterol level above 200 milligrams per deciliter (mg/dL). This applies to both men and women over age 20.
