Bad eating habits, increased stress and also sedentary lifestyle are the main causes for growth obesity indexes and also the increase in the incidence of many diseases, among them TheDiabetes Mellitustype 2. In the world today, there are 371 million people with diabetes, most of them being type 2 diabetes, which is caused by a poor lifestyle.
In order to identify a possible type 2 diabetes, it is important that you take periodic exams every year, including a glycemic curve exam. Know below what the glycemic curve exam is, know what it is and what it is for and understand better how this exam can help in controlling your health.
Carbohydrates in food
Often, carbohydrates are considered major villains in food, as over the last few years there has been an expressive of various diseases that are directly related to the consumption of refined carbohydrates and products containing sugar.
It is important to understand that all nutrients are essential for a complete well-being, but some types of carbohydrates can cause health damage.
Carbohydrates are macronutrients and these are abundant in nature, being much used for centuries by our society. The main function of this macronutrient is to promote energy to the organism and to all its vital functions, being rapidly converted into glucose so that it is transported to all cells of the body human.
According to theDietary Reference Intakespublished by the USDA, it is recommended that between 45% and 65% of the calories come from carbohydrates.
Carbohydrates considered healthy are found in fruits, vegetables, vegetables, grains and whole grains. Carbohydrates that are considered bad and should be avoided are contained in refined grains and sugar they include sweets, white breads, white pasta, soft drinks, concentrated juices, biscuits, ice creams, among many other products processed.

What is glycemia?
The term glicemia refers to the amount of glucose present in the blood plasma, being a very important for the verification and diagnosis of certain diseases and control of problems such as diabetes. When the glycemia rates are below normal, this characterizes a hypoglycemia, and when these exceed the values considered normal, this characterizes a hyperglycemia.
Glycemia is basically regulated by two hormones, insulin and glucagon. Insulin is a hormone produced by the pancreas that allows the entry of glucose into cells so that it is transformed into energy. Glucagon is also a hormone produced by the pancreas and has an opposite effect to that of insulin because it is responsible for the increase in the rate of sugar in the bloodstream.
When a fall in blood sugar occurs, leading to hypoglycemia, glucagon comes into play. This is responsible for breaking the stored glycogen in the liver into glucose and also for bringing this glucose back into the bloodstream to help normalize the blood sugar rate. In diabetic patients, high blood glucose levels may inhibit the release of the glucagon hormone, leading to severe hypoglycaemia.
The rate of glycemia will vary greatly depending on the foods that are ingested and this will determine the amount of the hormone insulin that should be released by the pancreas. Normal blood glucose levels should be between 70 mg / dL and 100 mg / dL under fasting conditions for healthy adults. Among the many tests that are performed for checking blood glucose rates are the glycemic curve test.
What is the glycemic curve exam and what is it for?
The glycemic curve is a blood test done in conjunction with an oral test to measure the body's glucose tolerance which is also known as Oral Glucose Tolerance Test (TOTG). This test checks the body's ability to process a certain amount of glucose and is usually used to diagnose a possible diabetes picture.
Type 2 diabetes is a chronic disease that can affect how the body metabolizes glucose, resistance to the effects of insulin, which is the hormone regulating the entry of glucose into cells. When the body does not produce this hormone adequately, a number of symptoms can arise, including scarring, urge to urinate several times a day, tingling in the feet, changes in vision, frequent infections, many others. Type 2 diabetes is serious and can be fatal.

The glycemic curve test should always be performed fasting from 8 to 14 hours and preferably in the morning. The patient is subjected to a glucose overload consisting of an aqueous solution of 25% and with 75 g of oral glucose. Blood samples are then taken to determine the glucose dosage at various times until it reaches 120 minutes after the ingestion of the solution called the glycemic curve. classic.
Some care should be taken prior to this type of examination. It is not recommended to perform physical exercises before it, since these can cause changes in the bloodstream. The use of medicines that may cause changes in the glycemic curve should also be avoided. and that have some interference in the metabolism of carbohydrates, among them the medicines laxatives.
The reference values that are considered for a normal glycemic curve used for the glycemic curve exam are 100 mg / dL of glucose in the bloodstream for fasting, and up to 140 mg / dL of blood glucose after 2 hours of ingestion of it. For a result above 125 mg / dL up to 200 mg / dL glucose, a new examination may be requested for confirmation of the result and proper diagnosis.
In addition to analyzing the glycemic curve to check for any change in glucose metabolism, the test may also include the curve insulin resistance, which consists of an examination to evaluate the increase of insulin in response to glucose overload and also the resistance to insulin.
Glycemic curve examination is one of the most important routine exams, helping to verify the blood glucose levels and being fundamental for the correct diagnosis of diseases such as diabetes. There are several factors related to the performance of this test that may present a normal insulin curve or may show changes in results. Performing routine exams is critical to maintaining lifelong health.
