is a fat (lipid) which is formed in a liver (about 80%) and plays huge value for good functioning of an organism. Cholesterol is in each cage of our organism, is used as construction material and takes part in production of sex and adrenal hormones.
- Other functions of cholesterol:
- Forms cellular membranes.
- Defines what molecules can get into a cage and what are not present.
- Takes part in formation of bile.
- Turns sunlight into vitamin D.
- D, E, K takes part in metabolism of vitamins A.
- Isolates nervous fibers.
Cholesterol is transported by means of special molecules – lipoproteida. They are three types:
- Lipoproteida of low density or "bad cholesterol". Transfer cholesterol from a liver to cages. If there is a lot of them in blood, there can be cardiovascular diseases.
- Lipoproteida of high density or "good cholesterol". Transports cholesterol back to a liver. Prevents cardiovascular diseases. In a liver cholesterol is split and removed from an organism.
- It is a universal form of fats. Coming to an organism, fats turn into triglycerides and remain in fat cages. Triglycerides together with cholesterol form "blood fats".
High level of "bad cholesterol" in blood can cause such diseases:
- Atherosclerosis – obstruction of arteries.
- Coronary heart trouble – injury of arteries which transport oxygen and blood in heart.
- Myocardial infarction – obstruction coronary arteries in a cardiac muscle. Result – death of a muscle.
- Stenocardia – insufficient intake of blood and oxygen in a cardiac muscle. Severe pain in heart.
- Stroke – obstruction of arteries which conduct to a brain. Because of the shortage of blood and oxygen of a cell of a brain die.
- Other cardiovascular diseases.
Symptoms of high level of "bad cholesterol" in blood:
- Yellow spots around eyes.
- Narrowing of coronary arteries of heart.
- Leg pains (arteries are narrowed and pass not enough blood and oxygen).
- Obstruction and rupture of vessels.
- Rupture of plaques.
The reasons of high level of "bad cholesterol" in blood:
- Food. Products rich with saturated fats: meat, sausage, hard cheese, fat, cream, flour products, pies, cakes, biscuits, etc.
- Inactive way of life. Physical exercises reduce amount of "bad cholesterol" in blood.
- Weight. People with an excess weight have the high level of "bad cholesterol" in blood.
- Smoking.
- Alcohol.
Methods of treatment of high level of "bad cholesterol" in blood:
- Sport
- Diet: fruit, vegetables, oats, whole grain, linen seed, garlic.
- Good dream (it is not less than 8 hours).
- Refusal of alcohol and smoking.
