What are the symptoms of high blood sugar during pregnancy?

The main symptoms of high blood sugar during pregnancy include frequent urination, thirst, increased appetite, and no significant weight gain. Specifically, elevated blood glucose levels in pregnant women lead to excessive glucose excretion through urine, which stimulates the kidneys and causes increased frequency of urination, known as polyuria. At the same time, due to the increased urination, the body tends to lose water, causing pregnant women to feel thirsty frequently and drink more water. In addition, high blood sugar can affect the appetite of pregnant women, making them feel hungrier and eat significantly more, but their weight may not increase accordingly, and even weight loss may occur. These symptoms are common manifestations of high blood sugar during pregnancy; however, many pregnant women may not exhibit any symptoms when their blood sugar rises. Therefore, routine prenatal screening tests are very important. If high blood sugar is detected, timely medical consultation, blood glucose monitoring, and treatment should be conducted to ensure the health of both mother and baby.
