• no solid food for 3-4 hours before the exam

Balloon Dilation of Achalasia Cardia

Pneumatic balloon dilation is a primary, non-surgical treatment for achalasia cardia that uses a high-pressure, 30–35 mm balloon to tear the muscle fibers of the lower esophageal sphincter (LES), improving swallowing.

• 2–3 Days Before: Switch to a Soft Diet.
• 24–48 Hours Before (The Day or Two Prior): Switch to a Clear Liquid Diet.
• The Night Before: Strict NPO (Nil Per Os): Do not eat or drink anything after midnight.
• In cases of severe esophageal dilation (mega-esophagus), the doctor may require a liquid diet for up to 72 hours.

Endoscopy Anesthetia

Endoscopy anesthesia focuses on providing patient comfort, amnesia, and stability during gastrointestinal procedures (EGD, colonoscopy, ERCP) through a continuum of sedation, ranging from moderate to general anesthesia.

• 8 Hours Before: No solid foods (though for Achalasia, you are likely on a liquid diet for days prior anyway)
• 2 Hours Before: ABSOLUTELY nothing by mouth. Stop drinking clear liquids. No gum, no hard candy, no smoking.
• If you drink water right before the procedure, it may be cancelled.
• The anesthesiologist or CRNA will ask about previous reactions to anesthesia

• No fasting needed
• Take regular medications
• Wear loose clothing (legs/arms exposed easily)
• Avoid smoking 1–2 hours before (nicotine narrows arteries → affects results)
