For individuals with mild to moderate vestibular disorders who are effectively managing their symptoms, flying is generally possible. However, understanding the condition and taking specific precautions is essential to minimize the risk of acute dizziness during a flight.

Vestibular disorders are balance-related conditions, categorized into peripheral and central types. They originate from the 8th cranial nerve and its connections. Damage to this system causes erroneous information transmission, leading to imbalance, blurred vision, dizziness, and tinnitus.

The inner ear's vestibular system processes information about body posture, movement, and balance. During takeoff or landing, pressure changes can stimulate this system if the Eustachian tube functions poorly or the inner ear is overly sensitive, potentially triggering symptoms. Additionally, aircraft turbulence during flight can force the vestibular system to constantly adjust. This leads the brain to receive inconsistent signals from the vestibular system and vision, resulting in lightheadedness, nausea, and dizziness. Psychological factors such as anxiety, stress, or fear of motion sickness also activate the sympathetic nervous system, affecting breathing and blood flow, which can worsen vestibular symptoms.

To ensure a smoother journey, several precautions are recommended. Before flying, patients should avoid alcohol and coffee, ensure adequate sleep, and consult a doctor for a check-up and disease assessment. Depending on the case, a doctor may prescribe medication to prevent dizziness or motion sickness, thereby reducing the risk of an acute episode during the flight.

During the flight, individuals with vestibular disorders should prioritize seats near the aircraft wings, as these areas typically experience less turbulence than the front or rear of the plane. Choosing an aisle seat also allows for easier movement if needed. Throughout the flight, keep your head stable, look straight ahead, avoid sudden head movements or bending your head down, and rest with your eyes closed. It is also advisable to avoid reading books or looking at screens for extended periods.

However, if you are experiencing an acute phase with severe rotational dizziness, significant nausea or vomiting, loss of balance, tinnitus, or sudden hearing loss, it is strongly recommended to opt for an alternative mode of transportation.
