Getting ready for an X-ray? One of the most common questions people ask is, “Can I eat or drink before my imaging appointment?” The answer depends on the type of X-ray you’re having. At Valence Medical Imaging, we want to make your visit stress-free and simple, starting with easy-to-follow X-ray dietary guidelines.
Knowing what to eat—or avoid—before your diagnostic imaging makes a big difference. It helps your images come out clear and accurate, so your doctor can make the best diagnosis and treatment plan.
Here’s your full guide to eating and drinking before an X-ray, with expert dietary advice for every type of imaging.
Why Your Diet Matters Before an X-Ray
Some X-rays require fasting to prevent food or drink from affecting the quality of the images. Others allow a light meal before your test. It all depends on what part of your body is being scanned.
When You Can Eat Before an X-Ray
You can eat and drink normally if you’re getting:
- A chest X-ray
- An arm, leg, hand, or foot X-ray
- A head or neck X-ray (unless otherwise instructed)
These tests don’t involve your stomach or digestive system, so fasting isn’t needed. However, always follow your X-ray prep instructions from the radiology team.
When You Should Avoid Eating or Drinking
You may be asked to fast for 4 to 12 hours before imaging if you’re getting:
- An abdominal X-ray
- A pelvic X-ray
- An X-ray with contrast (like a barium swallow or enema)
- Any X-ray that checks your stomach, intestines, or digestive organs
This helps keep your stomach empty, so there’s no gas or food that could block the view. It also helps prevent nausea if a contrast dye is used.
What to Avoid Before a Fasting X-Ray
If you’re told to fast, avoid the following:
- Solid foods of any kind
- Milk or dairy products
- Coffee or tea with cream
- Gum or candy
- Carbonated drinks
Stick to clear fluids only if allowed, like:
- Water
- Apple juice
- Clear broth (if instructed)
Do not eat or drink anything unless your radiologist or imaging team says it’s okay.
Special Instructions for Contrast X-Rays
If your test includes barium contrast or other dyes, you’ll be given extra X-ray fasting guidelines. You might need to:
- Drink a special prep liquid the night before
- Follow a clear liquid diet for 24 hours
- Avoid eating for 8 to 12 hours before your appointment
These tests require extra care, so follow every step in your X-ray prep form.
Medication and Medical Conditions
Still take your daily medications unless your doctor or radiologist says otherwise. If you have diabetes, kidney problems, or are pregnant, ask about special prep. A quick pre-imaging diet consultation can help you feel more confident and prepared.
Tips to Get Ready for Your Imaging Appointment
Here are a few helpful reminders to make the process smoother:
- Follow all fasting instructions exactly
- Bring your health card and referral form
- Arrive early for your appointment
- Wear loose, comfortable clothing
- Call your radiology center if you’re unsure about anything
