Whether you can drink coffee before a CT scan depends on the type of scan. If your CT scan involves contrast dye, it’s typically advised to avoid coffee and other caffeinated drinks for a few hours beforehand, especially if fasting is required, as hydration is important and caffeine can impact kidney function. If the scan does not involve contrast, drinking coffee is usually fine unless your doctor has given specific instructions otherwise. It’s always a good idea to check with your healthcare provider for clear guidelines.
Whether you can drink coffee before a CT scan depends on the type of scan and whether contrast dye is used. For a CT scan without contrast, drinking coffee is generally allowed. However, if contrast is required, especially oral or IV contrast, you may need to avoid coffee for a few hours before the scan, as caffeine can affect hydration and kidney function. Always follow the specific instructions provided by your healthcare provider to ensure accurate results and a smooth procedure.



There is no issue with drinking coffee and having a CT scan.
I would advice nothing to eat or drink at least one hour before your exam.
