Traveling with an ostomy is manageable but requires preparation, especially regarding how air travel affects the medical appliance. An ostomy is a surgically created opening on the abdomen that allows waste collection in an external pouch, often called a stoma bag. Stoma bags can inflate or “balloon” while on a plane, which is a normal and manageable reaction to changes in atmospheric pressure. Travelers can implement practical steps to prevent and manage this issue, ensuring a comfortable flight.
Why Stoma Bags Balloon at Altitude
The inflation of a stoma bag at altitude is due to simple gas physics related to changes in cabin air pressure. Commercial aircraft cabins are pressurized to simulate an altitude of 6,000 to 8,000 feet above sea level. As the aircraft ascends, the external pressure decreases, allowing gas within the digestive system and the sealed pouch to expand (Boyle’s Law). Although most modern pouches have charcoal filters designed to vent gas, these filters can sometimes become blocked by moisture or output. This blockage prevents the release of expanding air, resulting in the characteristic ballooning.
Essential Pre-Flight Preparation
Dietary Adjustments
Preventing excessive gas production starts with thoughtful dietary adjustments before the flight. For the 24 hours leading up to travel, adopt a low-residue diet to minimize intestinal output and gas. Avoid foods known to cause excessive wind, such as carbonated drinks, beans, and cruciferous vegetables like cabbage and broccoli.
Packing Supplies
Logistical planning requires careful packing of supplies. All essential ostomy supplies must be packed in a carry-on bag, as checked luggage can be lost or delayed. Pack at least double the amount of supplies typically needed for the trip to account for unexpected changes. Pre-cutting all appliance openings before leaving home is recommended, since scissors are prohibited in carry-on baggage. Finally, completely empty the pouch contents before boarding, ensuring the appliance is as flat and empty as possible.
Managing the Appliance While Airborne
Once airborne, the primary concern is managing gas accumulation during the ascent. If the pouch balloons, discreetly “burp” the bag to release the expanded air. For drainable pouches, open the tail slightly while in the lavatory, allowing the gas to escape before resealing. Proper hydration is necessary, as the low humidity increases the risk of dehydration, especially for those with an ileostomy. Sip water regularly, avoiding gas-promoting drinks like sodas or beer, and consider requesting an aisle seat near the restroom for quicker access.
Navigating Airport Security with an Ostomy
Passing through airport security is generally quick and respectful. The ostomy appliance may be detected by scanners, prompting security personnel to initiate a secondary screening. Travelers should discreetly inform the security officer about the medical device before the screening begins. Many ostomy users carry a Travel Communication Card, which explains their condition without requiring a verbal announcement. The standard secondary screening involves the traveler conducting a self-pat-down over the appliance, followed by the officer swabbing the traveler’s hand or clothing to test for trace elements. Travelers can request a private screening area if they are uncomfortable with the procedure being conducted in public.
