Many tests are performed during pregnancy, one of which is the glucose load test ordered for every pregnant woman between 24 and 28 weeks of pregnancy. Ensuring that the test is performed is very important because it helps to avoid the risk of many abnormalities in fetal development and minimizes the risk to the woman herself.

Why is too much glucose in the blood so dangerous?

Glucose in a woman's blood is not just in her bloodstream. It also penetrates the placental barrier, where it affects the baby's pancreas and forces it to produce more insulin.

It is a side effect too intensive child growth. Newborn babies of women with gestational diabetes usually stand out large birth weight. There is also a tendency to get through them lower Apgar score. Unfortunately, that's not all. The determination of blood glucose levels and, if necessary, starting treatment is also important from the point of view of the risk of fetal immaturity and the occurrence of obstetric complications. Perinatal injuries, preeclampsia and polyhydramnios are more common in women with gestational diabetes, while their children are at increased risk of developing neural tube defects and heart defects.

A woman suffering from gestational diabetes must take into account with a higher risk of termination of pregnancy by Caesarean section.

Bearing in mind what was written above: it should be clearly stated that it is the responsibility of every pregnant woman to perform a glucose load test. Detection of irregularities allows you to avoid all the abovementioned irregularities and bring pregnancy safely to the end.

How to prepare for a glucose load test during pregnancy?

Although some sources indicate that you do not have to go to the test on empty stomach, doctors and people working in the laboratory clearly emphasize that this is a prerequisite. You should hold your food 12 hours before the test. It's not everything. Gynecologists also recommend that you have dinner the previous day do not eat fruit or eat sweets. You can drink mineral water before the test.

For glucose load test we usually come in the morning, but you can do the test in the afternoon (as long as you take into account the above 12-hour non-eating requirements). In private establishments we can easily buy glucose, but it is best to buy it at the pharmacy (50 grams or 75 grams - depending on the doctor's prescriptions) and additionally buy lemon, whose juice will neutralize the too-sweet taste of the drink.

We dissolve glucose in 150 ml of water, about 2/3 cup of water.

What is the glucose load test?

An oral glucose load test (GCT) is performed between 24 and 28 weeks of pregnancy, which allows you to check how your body metabolizes sugar. In pregnancy, this process may be a little different due to the changed hormonal balance.

Before consuming glucose dissolved in water, a small amount is taken up finger blood which is the initial value (this value should not exceed 105 mg / dl).

After drinking the solution after an hour blood is drawn and the glucose level is determined (the correct value is less than 140 mg / dl). If the result is higher than 140 but lower than 180 mg / dl, an oral test with 75 g glucose is required.

In this case, your blood sugar level is measured after the first and second hours after drinking 75 g of glucose. Diabetes is diagnosed if the fasting blood glucose level is from 105 mg, after 180 mg and more, and after two hours 140 mg and higher.

Important information

  • glucose solution should be consumed within 5 minutes,
  • after drinking the solution, stay in one place, do not walk, do not move,
  • possible reactions: nausea, dizziness, weakness, increased sweating and even fainting,
  • lying down helps some women eat glucose (you can ask for it at the collection point, explaining the fear of vomiting)
  • you can also try to sit on the floor with your head between your knees (it helps some women)
  • it is worth considering taking an accompanying person for examination,
  • While waiting for your second blood donation, you must not eat anything. You can only drink natural mineral water.
  • stress, some medications (e.g. beta blockers, steroids) may affect the test result. Therefore, it is worth informing your doctor about taking them.

What other pregnancy tests should you do? Unfortunately, doctors often do not order everyone! See what you owe to NFZ and ensure good pregnancy.
