Fasting during pre-employment medical examinations generally does not allow drinking water, as doing so may affect the test results and lead to inaccuracies.

Fasting usually means abstaining from all food and drink for a certain period. Before medical checkups—whether pre-employment or other types—individuals are typically required to fast completely, avoiding both food and liquids. Patients should fast for approximately 8 hours, meaning they should refrain from eating or drinking anything after midnight the previous night to ensure accurate test results.

If one drinks water while supposed to be fasting before a medical exam, the water will enter the body and bloodstream, potentially diluting the blood. During blood tests, this could interfere with the results and compromise their accuracy. This is especially important in pre-employment physicals, where test outcomes can significantly impact hiring decisions. Therefore, to ensure successful employment, it's essential to follow the examination guidelines strictly.

In addition, patients should maintain a calm and positive mindset during the examination and avoid excessive nervousness. They should also refrain from taking any medications before the exam, as these might influence the test results.
