concentration of sugar in the blood is an important indicator of health.The body itself regulates blood glucose by insulin, which is secreted by the pancreas.If a person changes frequently sugar content in the blood, it can lead to diseases and disorders of metabolism.
By the way, high or low ratio may indicate the occurrence of pathological processes in the body (such as trauma, stress, infections, particularly hormonal disorders).That is why it is important to control the level of glucose, but not everyone knows how to donate blood sugar and what should be the preparation for this test.
Causes and symptoms increase in blood sugar
not always indicators of deviation from the norm is dangerous for health.High blood sugar is not always considered a disease and occurs virtually asymptomatic, if such jumps are temporary.
However, regular or chronic increase in blood glucose results in a whole range of serious complications: renal failure, neurological damage to the retina, cardiovascular disorder
Signs that may indicate an increased sugar, include the following:
- frequent hunger, gluttony;
- frequent bouts of thirst;
- polyuria (increased volume of urine);
- deterioration of visual acuity;
- increased fatigue, drowsiness;
- sudden weight loss;
- poor wound healing;
- dryness of the mouth;
- itchy skin;
- erectile dysfunction;
- cardiac arrhythmia;
- convulsions, coma.
rate of sugar in the blood glucose level
, usually in the morning (before the first meal) downgraded called post-level.Normal rate can range from 4.4 to 6.0 mmol / L, and the average is considered to be 5.5 mmol / L.During the day this value may vary slightly, but in general is in the normal range.To determine this amount, a person must take a blood test on an empty stomach.
After eating for an hour, this figure rises to several millimoles.Performance outside the normal range may be an indicator of the health of a person.Keeping a high level is called hyperglycemia, low - hypoglycemia.Persistent hyperglycemia shows the development of diabetes.
How to be tested for sugar
To control the level of glucose needed CBC.But how to donate blood sugar, they know not all.There are two types of tests to measure this indicator: Using the meter and analysis of blood from a finger or a vein.The advantage of the first method is its availability at home (need to purchase a device and regularly monitor their performance).Second performed in the laboratory and is considered more accurate and reliable.
But before you donate blood sugar, you should know some rules:
- before the analysis is not necessary to adhere to a special diet;
- analysis of the rent on an empty stomach, on the eve of it is not necessary to overeat;
- the results may be inaccurate if a person is sick (colds, sickness);
- the state of pregnancy can cause severe deviation of the results from the norm.
results obtained by the meter at home, give the opportunity to understand that an analysis of the blood, and also allow to observe how blood sugar levels affect different foods, physical activity or the presence of diabetes.This method is especially important for diabetics, who can control the disease and manage it on a daily basis.
to study the second method it is necessary to take a blood sample from a vein and conduct laboratory analysis of the sample in the blood sugar.If the index will be increased, then the exclusion of latent diabetes person will need to pass additional tests - oral test for glucose tolerance and determination of glycosylated hemoglobin in the blood.The essence of the first test is to measure the concentration of sugar fasting.Then the person takes glucose solution and the test is repeated in an hour and a half and two hours.The second test is to determine whether the increase in sugar in the blood over the last 3 months.
What raises blood sugar
often to reduce the blood glucose level, people resort to some foods that actually only aggravate the disease process.To include such food iskusstennye sweeteners.Studies have shown that substances such as saccharin, aspartame, sucralose and other sweeteners included in the composition may alter the microflora in the human intestine and induce unwanted changes in the body, such as glucose levels rise and the risk of developing diabetes.Therefore, before you donate blood for sugar, and in general for preservation of health should abandon such products.
which lowers blood sugar
Excessive reduction in the concentration of glucose in the blood is also a pathological phenomenon and its negative consequences for the organism.Its reduction by the following factors:
- poor diet, prolonged malnutrition, hunger strike;
- alcohol poisoning;
- diseases of the digestive system;
- metabolic disorders;
- an overdose of insulin for diabetes and so on.
to blood sugar has always remained within acceptable limits and does not affect the occurrence of pathological conditions, it is necessary to follow the simple rules:
- limit the intake of simple carbohydrates;
- follow the diet and avoid junk food;
- sports, lead an active and healthy lifestyle;
- watch weight.
