Dyslipidemia, or how what you eat affects your blood

For many years, cardiovascular disease has continued to be a leading cause of death in Europe and the world. According to a press release, one of the main risk factors for these diseases is dyslipidemia or, more simply, changes in blood fats.

“Dyslipidemia is primary when it is caused by genetic factors, in other words, inheritance or secondary when it develops due to an unbalanced diet, a high calorie, high fat and high fat diet, and lack of physical activity. Diabetes mellitus, chronic kidney and liver disease, thyroid dysfunction, and alcohol abuse can also contribute to the development of secondary dyslipidemia. This condition can occur at different ages, but it is especially dangerous for men over 40-45 years old, when atherosclerosis, angina, myocardial infarction or stroke can develop, “says I. Šapranauskienė.

She notes that a lipidogram helps assess the risk of cardiovascular disease. It is a test that measures the levels of total, ‘good’ and ‘bad’ cholesterol and triglycerides in the blood and evaluates their proportion. If your total cholesterol exceeds 7.8 mmol / l and your ‘bad’ cholesterol exceeds 6 mmol / l, you should be concerned. The higher these rates, the greater the risk of atherosclerosis.

In case of increased fat in the blood, it is recommended to consult a cardiologist, who will perform additional detailed tests and prescribe treatment.

Deceptive liver disorders.

The liver is extremely important, and often one of the most vulnerable internal organs. They help eliminate harmful substances from the body, but the abuse of alcohol, fatty foods and carbohydrates can irreversibly damage them in the long term.

By the way, liver disease: extremely misleading. In the early stages, these diseases often show no symptoms, and by the time they appear, the disease is already well advanced. Determining impending liver damage can be helped by measuring enzyme levels in a blood test.

What indicates that the liver is damaged?

GGT (gamma glutamyltranspeptidase) – one of the most sensitive indicators of liver damage. An increase in their activity may be evident in the early stages of the disease. This generally means liver damage due to long-term exposure to alcohol or toxins resulting from liver metastases.

ALT (GPT, alanine aminotransferase)An increase in the activity of the AST enzymes (GOT, aspartate aminotransferase) indicates alteration of the permeability of the parenchymal cells, developing liver damage. The nature of liver damage can be judged by which enzyme, AST or ALT, is most active.

ALP (alkaline phosphatase) increased activity is generally not associated with impaired liver function itself, but with occlusion of the large bile duct, for example, due to stone or cyst disease. Furthermore, an increase in ALP activity may indicate bone (osteoporosis, metastasis), sometimes intestinal pathology.

MCV (mean volume of erythrocytes) an increase is likely in patients with liver or bone marrow damage. Other possible causes are a lack of vitamin B12 or folic acid, hypoplasia of the bone marrow (underdevelopment). When folic acid deficiency is detected, the probable cause of the pathology is chronic alcoholism.

A common increase in bilirubin (liver pigment) can be caused by congenital and acquired liver diseases, such as Ziliber syndrome, when the liver cannot process bilirubin properly.

“If the listed liver function tests don’t change, the chances of liver damage are very low. In only 2% of cases, the pathological process of the liver occurs without significant changes in any of these indicators, ”says I. Šapranauskienė, head of the Laboratory Diagnostic Center.

Gout: a disease of those who like to eat a lot and deliciously

Gout is a fairly common chronic disease caused by a disorder of uric acid metabolism. For a long time, it was called the disease of the wealthy in society, because most patients consumed a lot of red meat, seafood and alcohol. The effect of food on the appearance of gout is undeniable. “Many years of observations have confirmed the assumption that gout attacks generally occur in people who are not indifferent to food,” says I. Šapranauskienė.

Gout is more common in men over the age of 40. In this disease, increased levels of uric acid in the blood and other body fluids cause sodium urate crystals. These crystals can settle in joints, tissues, and internal organs. The appearance of crystals in the joint causes acute inflammation of the joint – gouty arthritis. The joint suddenly swells, becomes red, you feel intense pain as soon as you touch it.

So if you suffer from joint pain, especially at night, drink a lot of alcohol, do not follow a diet, or if you have had a family history of this disease, you should have a blood test and blood test to assess your acid levels uric.

Preventive tests help prevent serious illness.

Unfortunately, it is common for us, until we endure serious problems, we still tend to shake hands with various health ailments, not to mention preventive check-ups. According to I. Šapranauskienė, such a faulty practice should be abandoned, because some even very serious diseases do not have obvious symptoms for a long time.

“Each of us should have a preventive health check-up at least once a year, perform the necessary preventive blood and urine tests. Their results can say a lot about our health and lifestyle, and most importantly, to help prevent serious diseases, “says I. Šapranauskienė.
