Black Coffee and Caffeine
While water is permissible, black coffee is off the menu. Here’s why:
- Caffeine: Coffee contains caffeine, which acts as a diuretic, promoting urine production. Increased urination can affect certain lab results.
- Fluid Balance: Although some believe coffee contributes to fluid intake, it can lead to dehydration due to its diuretic effect.
Medications and Fasting
- Over-the-Counter and Prescription Medications: Unless advised otherwise by your doctor, you can continue taking your daily medications. Common drugs like blood thinners and blood pressure medications won’t interfere with fasting bloodwork.
- Headache Relief: If you have a headache, taking an ibuprofen or another over-the-counter pain reliever won’t impact your test results.
Oops! I Forgot to Fast
If you accidentally ate or drank something before your blood test, don’t panic. Here’s what to do:
- Inform Your Doctor: Let your healthcare provider know about the slip-up.
- Avoid Unnecessary Tests: If your results come back normal, you’re likely okay. No need for unnecessary retesting.
