Definition of cholesterol
Cholesterol is a fatty substance that is the essential substance in the formation of cell membranes in all tissues of living organisms. Cholesterol also plays an important role in the process of metabolism, called metabolism. It is produced inside the body by several types of cells, All that the human body needs from it and push it to the blood to move to the rest of the cells, but cholesterol is another source to enter the blood of human food which is high in some foods such as meat and dairy products full fat.
And the high cholesterol level in the blood leads to the formation of deposits within the layers of the walls of arterial vessels, making them harder and harder to hard on the heart pumping blood, and it is also possible to break these deposits into small blood clots swim with blood until it faces a small artery Vtsdh, for example, An angina occurs in the heart, and if a brain artery causes a stroke.
Symptoms Associated With High Cholesterol
that Symptoms of high cholesterol Is not clear or even phenomenon, and it is possible to be a person with high cholesterol for a long time without knowing it only through blood tests, unless combined with other diseases, causing the following:
- CHD : It is one of the most common problems associated with the rise of cholesterol, which can be deposited inside the walls of the coronary arteries, causing stiffness in these arteries to make it difficult to pass the blood, and narrowing and reduce the proportion of blood flow in them, thus reducing blood flow to the heart muscle causing heart attacks or infarction Myocardial if the artery closes completely.
- brain attack : High atherosclerosis associated with high cholesterol may affect the arteries feeding the brain, any lack of cerebral perfusion or blockage of a cerebral artery leads to stroke.
- Endothelial diseases : Studies have shown that there is a strong relationship between high cholesterol and narrow peripheral arteries far from the heart and brain, where the fat deposits along the blood vessels, which causes the obstruction of blood flow, especially in the veins of the legs and feet.
- Hypertension : There is a close relationship between high cholesterol and high pressure as the lead hardening of the arteries and Tadhagaha because of the deposits of cholesterol and calcium to increase the voltage on the heart muscle, and makes them larger severely constrict to pay the blood in these vessels, and because blood pressure depends on two factors, namely the flow of heart strength, and the amount of vascular resistance So high cholesterol raises these two factors, leading to significantly higher pressure, which increases the risk of the heart muscle.
- Diabetes : Raise the proportion of sugar glucose in the blood ratio of harmful cholesterol and reduce the proportion of useful, which increases the risk of heart disease and accelerate the occurrence.
- Yellow tubers (yellow tumors) : Hypercholesterolemia is one of the causes of high cholesterol, a very high rate, as this sharp rise above (300 mg / dL) lead to the emergence of skin tubercles filled with yellow cholesterol either on muscle tendons, especially Achilles tendons in the foot, Or around eyelids.
- Erectile Dysfunction : The high cholesterol as mentioned earlier leads to damage to the blood vessels and this includes vessels feeding the reproductive organ, leading to weakness and inability to erect.
Cholesterol
The normal cholesterol in the body ranges from 140 to 200 mg / dL. Cholesterol is divided into two types. The first type is useful, a high-density lipoprotein, which must be higher than 40 mg / dL The second type, which is harmful, is a low-density lipoprotein, which must be less than 100 mg / dl in blood, which transfers cholesterol from the liver to the blood to be distributed to cells. Most organisms The real cores are made by integrating steroid, alcohol into the blood and yog Small proportions in the tissues of fungi and plant, while there is significant proportions in animal tissues, and it should be known that cholesterol is the basic building block that make hormones and vitamin D.
Cholesterol is produced by food and food. Cholesterol is also readily available in certain foods, such as shellfish, eggs, and shrimp. The liver and intestines produce cholesterol and then move to blood plasma through lipoproteins. When cholesterol is high in the blood due to food, Genetic factors cause many serious diseases such as atherosclerosis, heart infarction, angina or stroke due to blood clotting.
The high cholesterol is beneficial to protect against diseases called HDL cholesterol because it is beneficial to the body and harmless, and also transfers cholesterol beneficial to harmful cholesterol to the liver, which converts it to the gall bladder, but the beneficial cholesterol can not transfer all the amount of harmful cholesterol to the liver, leading to the deposition in the blood vessels Then blockage and lead to heart and kidney disease, and anyone can lower the cholesterol in the blood by eating a tablespoon of fish oil or the amount of one capsule a day.
Urgent treatment should be expedited especially if the cause of high cholesterol is due to heart disease and vascular disease.
