Gestational diabetes refers to the onset or first-time detection of varying degrees of hyperglycemia during pregnancy, including pre-pregnancy unrecognized glucose intolerance and diabetes. Typical clinical symptoms of gestational diabetes include polyuria, polydipsia, polyphagia, or recurrent vulvovaginal candidiasis. If the pregnant woman's weight is greater than or equal to 90 kilograms, and the current pregnancy is complicated by excessive amniotic fluid or macrosomia, there is also a high suspicion of gestational diabetes. In severe cases or those with poor blood sugar control, not only is there an increased risk of preterm labor but also miscarriage, and in severe cases, ketoacidosis may occur.

What is gestational diabetes?

The group of people who were diagnosed with diabetes before pregnancy is called gestational concurrent diabetes. Those who were not diagnosed with diabetes before pregnancy, but were diagnosed after becoming pregnant, are referred to as having gestational diabetes. Eighty percent of women are diagnosed with gestational diabetes, while twenty percent have gestational concurrent diabetes.

What should people with gestational diabetes eat?

For patients with various types of diabetes, the general principle of dietary control is low salt, low fat, and a diabetes-specific diet. This means that fats and calories must be controlled. However, pregnancy is a special period that requires an adequate intake of nutrients to meet the needs of the fetus. Therefore, gestational diabetes should be managed based on one's nutritional status, and, after evaluating one's condition, sufficient high-quality protein should be supplemented. It is advisable not to consume fats, such as chicken, duck, fish, and meat, but cooking methods should be chosen carefully. Fish can be consumed steamed, and meat can be steamed or stewed, as these meats are sources of protein. However, soup should not be consumed as it is particularly high in fat. Additionally, foods like pig's feet or animal organs, which have high cholesterol levels, should be consumed in moderation. The overall principle is the same as for diabetes, but it is essential to ensure the pregnant woman's nutritional needs are met and that the fetal weight gradually increases as the pregnancy progresses. Of course, if insulin intervention is needed to some extent, insulin must be used to keep blood sugar levels within the required range.

What are the symptoms of gestational diabetes?

The symptoms of gestational diabetes vary depending on the severity of the disease. Most cases of gestational diabetes are symptomless and are only detected when high blood sugar levels are found during diabetes screening. Therefore, it is recommended to perform a 75g glucose screening during pregnancy, at the very least, fasting blood sugar should also be checked because most diabetic patients do not notice any symptoms on their own. If the diabetes is more severe, the patient may experience symptoms such as increased thirst, increased appetite, weight loss, and frequent urination.

Can you drink yogurt if you have gestational diabetes?

Regarding yogurt, there are two scenarios. Currently, you can make yogurt at home with a yogurt maker. If it's homemade yogurt and you haven't added sugar, it is okay to eat because it contains probiotics and nutritious ingredients, which are actually beneficial for pregnant women. However, the yogurt sold in stores contains very high sugar levels because anyone who has made yogurt would know that unsweetened yogurt is very sour. The kind sold in stores tastes that way because a large amount of sugar is added, not to mention various additives. This is very unfavorable for blood sugar control in patients with gestational diabetes. Therefore, we recommend that pregnant women should drink less or even avoid commercial yogurt. In fact, we can obtain these nutrients by drinking regular milk, like pure milk.
