Does drinking water before a gestational diabetes screening test affect the results?

Patient's question:

I am 25 weeks pregnant. Yesterday, I went to the hospital for a gestational diabetes screening, and the results were good. This morning, I suddenly remembered that when I had this test yesterday, I was required to fast from 9 PM the night before until the screening was completed yesterday. However, when I woke up yesterday morning, I drank half a small cup of plain water, thinking that fasting only meant not eating breakfast. (I drank the water at 6:30 AM, and the test started at 8:30 AM.) Could this affect the test results? Do I need to go to the hospital again to have another test?

Doctor's answer:

Diabetes is an endocrine disease, primarily characterized by polydipsia, polyuria, polyphagia, and weight loss. However, many patients do not exhibit such typical symptoms, mainly showing elevated blood sugar levels.
Advice: If blood sugar remains consistently above normal, it indicates diabetes, and treatment should be initiated. Initially, dietary changes and exercise can be used. If these measures are insufficient to control blood sugar, additional hypoglycemic medications may be necessary. In daily diet, pay attention to controlling portions, avoiding excessive intake of high-sugar and high-starch foods, and regularly monitor blood sugar levels to adjust medications as needed. Wishing you good health and happiness.
