Pregnancy is a difficult period for the body of any woman.
When a fetus is born in the body of the future mother, simply “revolutionary” changes occur, the development of which is able to influence absolutely all the processes occurring in the tissues and organs.
Under the influence of hormonal changes, the organ systems begin to work more actively in order to provide decent living conditions not only for the woman, but also for the future baby.
Often, such changes provoke sudden sugar jumps. To control the situation, the future mother can be sent to undergo additional research, one of which is the glucose tolerance test.
The role of proper preparation for glucose tolerance test during pregnancy
The glucose tolerance test is one of the studies that provide the most accurate result and finally confirm or deny the presence of diabetes in a pregnant woman.
It lasts about 2 hours, during which the woman gives venous blood every 30 minutes.
Experts carry out the sampling of the biomaterial until the reception of the glucose solution and after it, which makes it possible to obtain detailed information on the change in indicators. Like many other options for research on sugar, this type of procedure requires careful preparation of the body for the collection of biomaterial.
The reason for such stringent requirements is that the level of glycemia in a person’s blood is impermanent and changes under the influence of various external factors, as a result of which it is impossible to obtain reliable results without prior preparation.
By eliminating extraneous influence, experts will be able to obtain accurate data on how exactly pancreatic cells will react to glucose in the body.
Glucose tolerance test - how to prepare for pregnant?
It is known that the glucose tolerance test is passed strictly on an empty stomach, therefore it is strictly forbidden to eat in the morning of blood sampling.
Also do not recommend to use any drinks, except for ordinary water without sweeteners, flavors and gases. The amount of water can not be limited.
Meals should be stopped for 8-12 hours before the appearance in the laboratory. If you go hungry for more than 12 hours, you run the risk of getting hypoglycemia, which will also be a distorted indicator with which all subsequent results cannot be compared.
What not to eat and drink before taking the test?
So, as we said above, for pregnant women who are taking a test for glucose tolerance, it is important to follow a diet.
To stabilize the glycemic level, it is recommended to moderate consumption or minimize in the diet:
- spicy and salty treats;
- smoked meat;
- Coffee and tea;
- sweet drinks (juices, Coca-Cola, Fanta and others).
However, this does not mean that a woman should completely eliminate carbohydrates and starve.
Eating foods with only a low hypoglycemic index or malnutrition will have the opposite effect in the form of low glycemia.
What can you eat and drink?
To maintain the level of sugar content at a stable level, eliminating its jumps, will help the presence in the basis of the diet:
- different types of porridge;
- low-fat boiled meat and fish;
- low-fat dairy products;
- fruits and vegetables;
- weak herbal tea.
It is advisable to include the listed products in the diet for a couple of days, making them basic in your menu.
Their slow absorption will contribute to the gradual penetration of glucose into the blood, as a result of which the sugar level will remain approximately at the same level during the entire preparation period.
What else needs to be considered before donating blood for sugar?
In addition to the correctly chosen products and well-organized ration, the observance of some other simple rules, the neglect of which will negatively affect the result of the study, is equally important.
So, if you received a referral for a glucose tolerance test, follow these rules:
- if you were nervous the day before, put the study aside for a couple of days. Stressful situations distort hormones that, in turn, can provoke either an increase or a decrease in glucose level;
- You should not take the test after X-rays, physiotherapy, as well as during a cold;
- if possible, medication containing sugar, as well as beta-blockers, beta-adrenomimetic and glucocorticosteroid drugs should be excluded. If you cannot do without them, take the right medication immediately after completing the test;
- Before going to the laboratory, you should not brush your teeth or freshen breath with chewing gum. They also contain sugar, which instantly penetrates the blood. As a result, you will receive initially incorrect data;
- if you have a strong toxicosis, be sure to warn your doctor about this. In this case, you do not have to drink a solution of glucose, the taste of which can only aggravate the condition. The composition will be administered to you intravenously, which will exclude the occurrence of bouts of vomiting.
In some publications, you can see the following advice: “If there is a park or a square near the laboratory, in the intervals between blood sampling you can walk through its territory”. This recommendation is considered by most experts to be incorrect, since any physical activity may contribute to a decrease in blood sugar levels.
But experts, it is important to see what kind of reaction will be the pancreas without the influence of external factors. Therefore, in order to avoid errors in the results, it is better not to neglect the previously established rule.
What time do I need to test for glucose tolerance?The glucose tolerance test is carried out in the morning and always on an empty stomach.
According to experts, it is at this time that it is easiest for a patient to withstand a long hunger strike at the expense of hours of nighttime sleep.
Theoretically, provided that the preparation rules are properly followed, the test can be taken at any time of the day.
But, taking into account the fact of convenience, most medical centers still take blood for analysis from patients in the morning.
How to prepare for the glucose tolerance test during pregnancy:
Competent preparation for glucose tolerance test is the key to a correct result and correct diagnosis.
The study of the dynamics of indicators in the testing process makes it possible not only to confirm gestational diabetes in a pregnant woman, but also to identify less large-scale pathologies associated with impaired carbohydrate metabolism.
