Too much of lipid and/or lipoproteins in the blood can lead to hyperlipoproteinemia. Hyperlipoproteinemia is also known as hyperlipemia or hyperlipidemia and is a metabolic disorder. This disease remains silent for years together; only when the person suffers any heart ailment does this condition come to light. Heredity and diet play a major role in the onset of this disease; hereditary blood fat disorders are the main cause for Hyperlipoproteinemia.
Other common conditions that can cause this condition are diabetes, liver and kidney disease, hypothyroidism, alcohol and cigarette smoking. Few medications like progesterone, beta blockers, etc also increase the fat level in the bloodstream. If left unattended or untreated hyperlipoproteinemia can lead to cardiovascular and cerebrovascular diseases. This condition is common in adults rather than in children and can occur both in men and women. Depending on the excessive chemical found in the blood stream, hyperlipoproteinemia can be classified into five types:
Type I – Elevation of triglycerides
Type II – Elevated cholesterol and in few cases elevated triglycerides
Type III – Elevated cholesterol and triglyceride levels with subsequent vascular diseases
Type IV – Elevated triglycerides alone but no risk of vascular diseases
Type V – Similar to type I
No specific symptoms are shown for hyperlipoproteinemia. In very rare cases when the fat level in the blood shoots up too high, fat gets deposited in the form of bumps in the skin and tendons, this is referred to as xanthomas. In few cases, the liver and spleen enlarge when the triglycerides level shoot up too high. This leads to Pancreatitis causing severe abdominal pain. The diagnosis of hyperlipoproteinemia can be made by measuring the triglycerides, total cholesterol, lipid profile, LDL and the HDL levels in the blood.
Lipoprotein (a) Test
Lipoprotein (a) is synthesized by the liver and is responsible for the initial onset of cardiovascular disease. It is generally found in the inner arterial lining leading to the accumulation of plaque and formation of atherosclerotic particles. This process occurs due to the initiation of foam cell accumulation which gradually leads to the formation of plaque in the coronary arteries. Lipoprotein (a) test is prescribed to analyze the probabilities of premature cardiovascular disease incidence.
Lipid profile under normal or slightly elevated values may have an underlying risk indicating the development of a cardiovascular condition which can be specifically determined by estimating the blood lipoprotein (a) value. The occurrence of lipoprotein (a) levels is a genetic cause which induces the onset of cardiovascular disease. The lifestyle of an individual in relation to cardiovascular disease is not an important factor for the increased lipoprotein (a) values. Lipoprotein (a) has structural similarity with blood clotting factors such as plasminogen which can lead to the formation of blood clots. Increased LDL values may associate with lipoprotein (a) in facilitating cardiovascular disease. The normal value of lipoprotein (a) is 30mg/dl. The test for lipoprotein is usually taken after 12 hours fasting.
Dyslipidemia indicates the presence of increased cholesterol in the blood. In general the cholesterol in the body is categorized as good and bad forms, thus referring to its functionality. Good cholesterol also known as high density lipoproteins are required for the body to carry out regular metabolic activities. Estimation of triglyceride levels in the blood serves as a key factor in identifying the amount of disordered fats in the body or dyslipidemia. Dyslipidemia is one of the important causes for the onset of coronary artery disease.
Clinical evaluations of blood cholesterol levels
Clinical presentation of blood cholesterol levels aids estimation of the onset of conditions such as dyslipidemia which leads to cardio vascular disease. Blood cholesterol determination includes the estimation of high density lipoproteins, triglycerides and low density lipoproteins. Values in the case of dyslipidemia contain increased total cholesterol levels i.e. high LDL levels and decreased HDL levels. These levels are checked on fasting for at least 10 hours. Clinical interventions are recommended in the treatment of dyslipidemia to understand the possibility of cardio vascular disease in a patient and to differentiate the primary and secondary categories of this disease.
Diabetes and dyslipidemia
Type 2 diabetes is an underlying medical condition in which dyslipidemia is often noticed. It is measured by the lipid profile analysis. Insulin resistance is the predominant cause of low serum HDL. Insulin resistance promotes another condition called hypertriglyceridemia. This eventually leads to the increase of LDL or low density lipoproteins in the blood which can initiate the onset of atherosclerosis. Patients suffering diabetes with increased values of LDL and VLDL fall under the risk group for coronary artery disease. In addition to this, the metabolism of lipids is directly associated with the release of thyroid hormone. In patients with diabetes and hypothyroidism, the chance of cardiovascular disease is imminent.
Dyslipidemia can occur because of various factors. Most of them are induced by altered lifestyle patterns affecting the metabolism of a person. Obesity is the predominant cause of cardiovascular disease which is directly associated with the presence of dyslipidemia in the person. Symptoms associated are lethargy, gasping and difficulty in participating in any kind of physical activity. Alcohol consumption is also a major cause for the onset of dyslipidemia as it is related to the damage caused to the liver which produces major enzymes for lipid metabolism and fat emulsification processes. Other caused include Cushing's syndrome, Polycystic ovarian disease and liver cirrhosis.
Dyslipidemia is a condition which is treated with effective counseling about healthy lifestyle choices. Eating right and handling stressful factors can subsequently act on the regulation of metabolism. Patients are advised to exercise regularly to prevent the onset of atherosclerosis caused because of dyslipidemia.
