One of the most common questions we hear at Lagos ultrasound scan centres is: "Can I eat before my scan?" The answer depends on which type of ultrasound you're having. Here's your complete guide to fasting requirements for different scans in Lagos.
When You MUST Fast (No Food or Drink)
Abdominal Ultrasound (Liver, Gallbladder, Pancreas, etc.)
⏰ Fast for 4-8 hours before
✔ Why? Food causes gas that blocks organ visibility
✔ Small sips of water allowed
Tip: Schedule morning scans to fast overnight comfortably
✅ When You CAN Eat Normally
1. Pregnancy Ultrasounds
✔ Eat light meals to avoid nausea
✔ Exception: Very early scans (<8 weeks) may need a full bladder)
2. Thyroid/Neck abd Scrotal Ultrasound
✔ No restrictions
3. Breast Ultrasound
✔ No fasting needed
4. Musculoskeletal (Joint/Soft Tissue) Scans
✔ No preparation required
⚠️ Special Cases
For Diabetics in Lagos:
✔ Take morning medications with tiny water sips
✔ Bring snacks to eat immediately after your scan
✔ Inform your sonographer about your condition
Pediatric Scans:
✔ Babies/toddlers: 2-4 hour fast (consult your doctor)
💡 Why Preparation Matters
✔ Clearer images = More accurate diagnosis
✔ Avoids repeat scans (saves time & money)
✔ Prevents inconclusive results
Common Scenario: Patients who eat before gallbladder scans often get unclear results and need to reschedule.
