Hypercholesterolemia - high cholesterol

Cholesterol can be inherited. Foodsfat consumed can also determine,hypercholesterolemia.
Causes include:
- Diet. Eating too much saturated fat cancholesterol increases. Theseunhealthy fats are found in products ofanimal. Beef, pork, veal, milk, eggs,butter and cheese contain saturated fat. Foodpackages that contain coconut oil, palm oil, orcocoa butter contain high amounts of fatsaturated. Margarine, fats and mostcookies, crackers, chips and other snacks containalso saturated fat- Body weight. Increased body weightit increases levels of triglycerides and HDL decreases the- Level of activity. Lack of physical activityincrease LDL and HDL it decreases the- Age and sex. After the age of 20 years, levelscholesterol begin, naturally, to grow. Tomen, cholesterol levels stop risingaround the age of 50 years. In women, are maintained bymenopause, then grow to levelscholesterol in men- General health. Some diseases, such asdiabetes or hypothyroidism, increasescholesterol levels- Family history. If there are morepeople who have high levels of familycholesterol (familial clustering exists), itdisease is inherited- Smoking. This can usually decreasesgood cholesterol.
In rare cases, cholesterol can be determinedan inherited condition called dyslipidemia, whichchange how the body uses cholesterol.People with this disorder can have total levelscholesterol over 250 mg / dl. Certain types ofinherited dyslipidemia can be difficult to treat.SymptomsCholesterol does not cause symptoms. It isusually discovered during analysis of bloodroutine, which causes increased levels oftriglycerides and cholesterol. Can be foundwhen another disease is diagnosed, determinedin part of hypercholesterolemia, such as for examplecoronary artery disease, strokestroke, peripheral arterial disease or inflammationthe pancreas. Some people with dyslipidemia, such asfamilial hypercholesterolemia may have symptomsdistinct, such as cholesterol deposits on skin(Xantoame). Cholesterol may be submitted also intendons hands or feet.Mechanism fiziopatogeneticSusBoth elevated LDL levels, and levelslow HDL cholesterol can lead to deposition inartery walls (plaques). This accumulation, calledatherosclerosis, hardens and narrows arteries and reducesblood flow to tissues, including the myocardium(Heart muscle).
Atherosclerosis can lead to:
- Coronary artery disease that causes painchest, heart attack, heart failure orarrhythmias (irregular heartbeat)- Stroke or strokestransient brain. Atherosclerosis whenaffects the blood vessels leading to the brain,can cause strokes ortransient strokes.- Peripheral arterial disease is caused byatherosclerosis of blood vessels that nourish hands,legs and other parts of the body. Reductionblood flow to leg cramps causethe calves, thighs and buttocks. Levelscholesterol naturally, with the advance inage. Also increases after menopause in women and thatresult of other diseases such as diabetes.Risk FactorsSome factors that increase riskhypercholesterolemia can be controlled. It is verysignificant decrease in risk as much as possible.Risk factors that can be controlled
Risk factors that can be controlled include:
- Diet high in saturated fat and cholesterol, whichincrease the level of LDL cholesterol and lowers cholesterol HLD- Increased body weight, which increases the level ofLDL and HDL decreases- Lack of physical activity that increases LDL and decreasesHDL- Smoking can lower HDL by 15%.
It is possible to control some of the diseases that increasecholesterol levels, including diabetes.
Risk factors that can not be controlled
- Family history. Coronary artery disease in relativesyounger than 55 years in men and younger than 65years for women means that people in this familyhave an inherited tendency for hypercholesterolemia- Age and sex. After the age of 20 years, levelscholesterol begin, naturally, to grow. Tomen, cholesterol levels stop risingaround the age of 50 years. The women keep up tomenopause, then grow to levelscholesterol in men.Call a specialitateSusHypercholesterolaemia is not usually anysymptoms. Sometimes the first sign of hypercholesterolemiais a heart attack, strokeor transient stroke. If thereany of these symptoms, it is recommendedcall 911 or other emergency service.
