Preparation for Your Full Body Checkup

---

The Day Before Your Check-up

Fasting

• Have a light meal before 8:00 PM.
• After 9:00 PM: no food. Water is permitted until you begin your fasting window.
• If you have indigestion, eat only porridge and finish by 6:00 PM.
• Your full fasting window (no food, water, gum, or smoking) begins 10 hours before your appointment time.
• Avoid alcohol, smoking, and overexertion. Get a full night's sleep.

Medications

• If you are under ongoing medical treatment, consult your doctor before the checkup.
• If you are scheduled for a gastroscopy or colonoscopy, and you take blood thinners (Aspirin, Coumadin/Warfarin, Plavix, etc.), consult your doctor first — biopsy may not be possible if taken within the last 7 days.

Female Patients

• Urine and cervical cancer tests should be done 5–7 days after menstruation ends.
• Avoid intercourse or vaginal suppositories 24 hours before a cervical cancer test.
• Mammography and breast ultrasound are restricted for clients who are breastfeeding.

Pregnancy

• Confirm pregnancy status before your checkup. Most tests can be performed during pregnancy except X-rays. Health checkups are generally not recommended during pregnancy, as standard prenatal care covers most of the same screenings.

• Remove nail accessories (cubic stones, etc.) from at least one finger before your visit.
