How cholesterol does affect our physical living? What's the hazardous effect of having much cholesterol? Many questions are frequently asked by people having an excessive amount of body fat. Having High Cholesterol count on the blood is a dangerous sign or causes of having a heart disease or might cause heart problems. Cholesterol is a waxy, fatlike substance that your body needs to function normally.
Cholesterol is naturally present in cell walls or membranes everywhere in the body, including the brain, nerves, muscles, skin, liver, intestines, and heart. Your body uses cholesterol to produce many hormones, vitamin D, and the bile acids that help to digest fat. It takes only a small amount of cholesterol in the blood to meet these needs. If you have too much cholesterol in your bloodstream, the excess may be deposited in arteries, including the coronary (heart) arteries, where it contributes to the narrowing and blockages that cause the signs and symptoms of heart disease. High cholesterol is more common in men younger than 55 years and in women older than 55 years.
High cholesterol is the best known of all the many threats to a healthy heart. When excess amounts of this waxy, fat-like substance build up along the walls of the arteries, you face a dramatically higher risk of a complete blockage, leading to a heart attack or stroke. At normal levels, cholesterol is not a bad thing. On the contrary, it's an essential raw material used by the body to build cell walls and produce hormones such as estrogen and testosterone. The body produces its own supply of cholesterol in the liver, and it's found naturally in all animal products (such as meats, eggs, milk, and cheese). It poses a problem only when the body is unable to use or eliminate excessive supplies. Cholesterol is classified as a lipid. It is carried through the bloodstream attached to proteins, forming complexes called lipoproteins. There are two major types of lipoproteins: the low-density lipoproteins (LDL) commonly known as "bad" cholesterol, and the high-density lipoproteins (HDL) usually dubbed "good" cholesterol. It's the "bad" cholesterol that tends to form deposits on the artery walls. HDLs, on the other hand, help to clear excess cholesterol from the bloodstream. The ideal situation to aim for, then, is a low level of LDL cholesterol, a high level of HDL cholesterol, and a moderate total of both.
There are several factors that affect the level of cholesterol of our blood. Some causes are sometimes hereditary, that genetically influence the level of bad cholesterol in a person's blood. Excess weight may modestly increase your LDL (bad) cholesterol level. If you are overweight and have a high LDL cholesterol level, losing weight may help you lower it. Weight loss especially helps to lower triglycerides and raise HDL (good) cholesterol levels. Mental stress is one factor of the abnormal increase of LDL or bad cholesterol. Several studies have shown that stress raises blood cholesterol levels over the long term. One way that stress may do this is by affecting your habits. For example, when some people are under stress, they console themselves by eating fatty foods. The saturated fat and cholesterol in these foods contribute to higher levels of blood cholesterol. Many risk factors affect the cholesterol level of the body, proper diet and self-discipline helps neutralize the body's cholesterol count.
