A fatty substance that your body needs in order to function is cholesterol. Cholesterol helps form the cells that make up your body, it is made in the liver and is also found in some foods we eat. Excessive levels of cholesterol can be harmful to your body and can increase your risk for artery and heart disease.
Carriers of cholesterol in your blood include triglycerides, the major form of fat that moves through your blood stream.
Steep triglyceride levels could increase your risk for heart disease.
They might also show that you have or are at risk for diabetes. Sugar and alcohol can affect the blood triglyceride level. Weight loss if you are over weight, as well as decreasing your level of sweets and alcohol can help lower triglyceride levels.
Bad Cholesterol Low Density Lipoproteins (LDL)
As far as cholesterol goes Low Density Lipoproteins (LDL) are considered the "worst of the worst". Too much of this “bad” cholesterol in your blood can build up in your vessels. Such a build-up can cause vessels to constrict and narrow. This makes it hard for blood to travel and nourish the organs, which can often lead to a heart attack.
Good Cholesterol High Density Lipoproteins (HDL)
Then there are High Density Lipoproteins (HDL). The higher levels of HDL cholesterol are associated with a lower risk of heart disease. HDL is known as the “good” cholesterol as it tends to carry the extra cholesterol in your blood back to the liver so your body can get rid of it. If after testing it is discovered that your HDL level is too low, lifestyle changes might help. Changes such as a healthier diet, more exercise and no alcohol or tobacco use may also help prevent other diseases, and make you feel better overall.
