Plus, the risks from high cholesterol aren't immediate. The damage accumulates over years -- even decades. High cholesterol in your 20s and 30s can take its toll in your 50s and 60s.
There is no set period in which cholesterol is guaranteed to drop. Cholesterol-lowering drugs usually produce a change in LDL within 6 to 8 weeks. It is possible for lifestyle changes to change cholesterol levels within weeks. However, it may take longer, usually about 3 months — sometimes more.
Completely reversing it isn't possible yet. But taking a statin can reduce the risk of complications from atherosclerosis. It fights inflammation, which stabilizes the plaque. For this reason, statins are often key to treating atherosclerosis.
With high cholesterol, you can develop fatty deposits in your blood vessels. Eventually, these deposits grow, making it difficult for enough blood to flow through your arteries. Sometimes, those deposits can break suddenly and form a clot that causes a heart attack or stroke.
Untreated or undertreated high cholesterol is associated with a lower life span due to the risk of heart attack and stroke, but it's still possible to live a long life with high cholesterol, provided you follow a heart-healthy lifestyle and take medication if needed.
The American Heart Association recommends that all adults have their cholesterol checked every 4 to 6 years, starting at age 20, which is when cholesterol levels can start to rise. As we age, cholesterol levels tend to climb. Men are generally at a higher risk than women for higher cholesterol.
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.
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.
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.
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.
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.
Fill Up on Fiber
Foods like oatmeal, apples, prunes, and beans are high in soluble fiber, which keeps your body from absorbing cholesterol. Research shows that people who ate 5 to 10 more grams of it each day saw a drop in their LDL. Eating more fiber also makes you feel full, so you won't crave snacks as much.
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.
Does what you eat before the test matter? Consuming a double cheeseburger, fries, and a milk shake right before having your blood drawn for a cholesterol test may lead to a follow-up fasting test if the triglycerides are very high. But eating normally has little effect on your lipid levels, including triglycerides.
For example, a diet rich in soluble fiber, plant sterols, and vegetable protein sources, such as soy and nuts, reduced LDL cholesterol by an average of 28.6% in just 4 weeks.
Types of Cholesterol
Levels of LDL cholesterol higher than 130 milligrams per deciliter (mg/dL) are linked to an increased risk for ischemic stroke.
Total cholesterol of 5.8mmols/l is higher than recommended, but could be reduced with simple diet and lifestyle changes rather than medical treatment.
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.
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.
If there's too much cholesterol in the blood, the cholesterol and other substances may form deposits (plaques) that collect on artery walls. Plaques can cause an artery to become narrowed or blocked. If a plaque ruptures, a blood clot can form. Plaques and blood clots can reduce blood flow through an artery.
Medication is typically recommended when: your cholesterol levels are high enough to increase your risk for cardiovascular disease (or you already had a cardiovascular event, such as a heart attack or stroke) you have an LDL level greater than 190 milligrams per deciliter (mg/dL)
