Will Drinking Water The Day Before The Fasting Blood Sugar Test Affect The Results Of The Examination?
Dear doctor … my father has high blood sugar and wants to go to the hospital. Usually a blood check is performed, which is told to fast at least 8 to 10 hours. But in the morning my father drank water. Does it affect the results of blood checks? Because he chose to postpone to check his blood tomorrow.
Hello Sharah, thank you for the question.
Fasting blood sugar examination is an examination carried out to determine the amount of sugar in the blood after a person fasts for at least 8-10 hours beforehand. Fasting that is intended in this examination is mainly to do fasting from consuming foods or drinks that contain sugar or other caloric content which if consumed can obscure the amount of sugar that is in the actual blood, where if the results are used it can lead to misdiagnosis of diagnosis or therapeutic decline. blood sugar level.
Regarding the consumption of water that is done the day before the examination, it will not affect the results of fasting blood sugar tests the next day because fasting in excess of the specified time will not give better examination results, but may cause worse side effects such as for example electrolyte disturbances, dehydration, kidney damage, and so on. So if indeed your father decides to postpone the examination, your father can eat and drink as usual, but is limited to 8-10 hours before conducting the examination the next day.
I hope this helps.
