Dangers of Low HDL From the standpoint of heart health, the total cholesterol level can never be too low. A problem, however, arises when the HDL drops below 40 mg/dL. Quite simply, the less HDL there is in your blood, the less LDL you can clear from the body.

Several studies have suggested that the keto diet can affect cholesterol levels. When people consume low amounts of carbohydrates, the liver produces fewer triglycerides, which may be involved in raising HDL cholesterol levels. However, the keto diet may raise LDL cholesterol levels in some people.

When there is too much cholesterol in your blood, it builds up in the walls of your arteries, causing a process called atherosclerosis, a form of heart disease. The arteries become narrowed and blood flow to the heart muscle is slowed down or blocked.

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).

LDL cholesterol levels should be less than 100 mg/dL. Levels of 100 to 129 mg/dL are acceptable for people with no health issues but may be of more concern for those with heart disease or heart disease risk factors. A reading of 130 to 159 mg/dL is borderline high and 160 to 189 mg/dL is high.

Reduced levels of LDL 'bad' cholesterol were seen in those women who ate at least five servings of nuts a week. This was only true of those women who had blood samples available, which was around one-fifth of participants. Levels of HDL 'good' cholesterol were not increased.

On a low-carb diet, HDL tends to go up and triglycerides down, while Total and LDL cholesterol tend to stay the same. LDL particle size tends to increase and LDL particle number tends to go down.

HDL is considered good because it takes the bad LDL out of your blood and keeps it from building up in the arteries. The standard recommendation has been to keep HDL levels high (40 to 60 milligrams per deciliter [mg/dL]) and LDL low (less than 100 mg/dL). (See "Lipid levels in adults.")

For HDL cholesterol, or "good" cholesterol, higher levels are better. High-density lipoprotein (HDL) cholesterol is known as the "good" cholesterol because it helps remove other forms of cholesterol from your bloodstream. Higher levels of HDL cholesterol are associated with a lower risk of heart disease.

Trans fats raise your LDL (bad) cholesterol. They also lower your HDL (good) cholesterol. High LDL along with low HDL levels can cause cholesterol to build up in your arteries (blood vessels). This increases your risk for heart disease and stroke.

Certain medicines, including steroids, some blood pressure medicines, and HIV/AIDS medicines, can raise your LDL level. Other medical conditions. Diseases such as chronic kidney disease, diabetes, and HIV/AIDS can cause a higher LDL level.

HDL takes the "bad," LDL (low density lipoprotein) cholesterol out of your blood and keeps it from building up in your arteries. LDL cholesterol is known as bad cholesterol because it leads to the development and build up of plaque on the walls of your arteries.

HDL (high-density lipoprotein), or “good” cholesterol, absorbs cholesterol and carries it back to the liver. The liver then flushes it from the body. High levels of HDL cholesterol can lower your risk for heart disease and stroke.

It is sometimes called the "bad" cholesterol because a high LDL level leads to a buildup of cholesterol in your arteries. HDL stands for high-density lipoproteins. It is sometimes called the "good" cholesterol because it carries cholesterol from other parts of your body back to your liver.

Losing as little as 5% of your body weight can lower your cholesterol levels. One study found that adults who took part in a 12-week exercise program lowered their LDL by 18 points, and their total cholesterol dropped 26 points.

Your LDL cholesterol number is: Optimal if it is less than 100. Near optimal/above optimal if it is 100-129. Borderline high if it is 130-159.

Triglycerides are not a type of cholesterol, but they are part of a lipoprotein panel (the test that measures cholesterol levels). A normal triglyceride level is below 150 mg/dL. You might need treatment if you have triglyceride levels that are borderline high (150-199 mg/dL) or high (200 mg/dL or more).
