Vertigo in underwater diving

Vertigo can be a significant concern for individuals who engage in underwater diving, as the unique physical and environmental conditions associated with diving can exacerbate balance and vestibular issues. The combination of changes in pressure, movement, and the underwater environment can contribute to the onset of vertigo, and for some individuals, it can pose risks to both their safety and well-being.

1. The Impact of Diving on Vertigo

A. Pressure Changes

• Barotrauma: During diving, changes in water pressure can affect the inner ear, which is responsible for balance. If the pressure inside the middle ear and the surrounding environment is not equalized properly, it can lead to discomfort, pain, and vertigo (known as barotrauma).
• Equalization: As a diver descends and ascends, the change in pressure can affect the Eustachian tubes and the vestibular system, which controls balance. Failure to properly equalize the pressure in the ears can trigger dizziness and vertigo.

B. Motion Sickness

• Disorientation: The sensation of movement underwater, coupled with the limited visual references, can lead to disorientation. This is especially true if there is any turbulence or rapid movement while diving. Some divers may experience motion sickness, which can cause dizziness and vertigo.
• Sensory Mismatch: The vestibular system, which controls balance, relies on visual and sensory input. If there is a mismatch between what the eyes see and the balance system feels (such as when the diver is moving underwater but doesn’t perceive it visually), it can lead to dizziness or vertigo.

C. Decompression Sickness

• Nitrogen Narcosis: Also known as “the bends,” nitrogen narcosis occurs at deeper depths, where the increased pressure can cause nitrogen to dissolve into the bloodstream and affect the central nervous system. Symptoms can include confusion, dizziness, nausea, and vertigo. This condition is typically reversible with ascent, but it can be dangerous if not recognized early.
• Decompression Sickness: If a diver ascends too quickly after spending extended periods at great depths, the nitrogen in the blood can form bubbles, leading to decompression sickness. Symptoms may include dizziness, vertigo, joint pain, and other neurological effects.

2. Types of Vertigo Experienced While Diving

A. Peripheral Vertigo

• Benign Paroxysmal Positional Vertigo (BPPV): BPPV is a common condition where small crystals in the inner ear become dislodged, leading to brief but intense episodes of vertigo when the head is moved in certain positions. For divers, BPPV can be triggered by sudden head movements or by the position changes associated with diving.
• Vestibular Disorders: Underwater environments can exacerbate pre-existing vestibular conditions, leading to vertigo. For example, Meniere’s disease (a disorder of the inner ear) or labyrinthitis (inflammation of the inner ear) may worsen in high-pressure conditions.

B. Central Vertigo

• Diving-Related Dizziness: If there are issues related to oxygen or blood flow, such as hyperventilation or hypoxia (low oxygen levels), the brain may experience dizziness or vertigo. These symptoms may not be strictly related to the inner ear but rather to neurological or circulatory changes caused by the diving environment.

3. Managing Vertigo While Diving

If you have a history of vertigo or balance disorders, special precautions need to be taken to safely dive without triggering or worsening vertigo. Here are some strategies for managing vertigo while diving:

A. Medical Evaluation

• Consult a Physician: Before starting any diving activity, individuals with vertigo or balance disorders should seek medical evaluation from a doctor, preferably one with experience in diving medicine. Your doctor can assess whether it’s safe for you to dive and recommend the necessary precautions.
• Vestibular Testing: Some individuals may undergo vestibular testing to assess their balance and inner ear function before participating in diving activities. If a vestibular disorder is detected, treatment options or recommendations for limiting diving may be discussed.

B. Proper Equalization

• Ear Equalization: Ensuring proper equalization of the ears is crucial to avoid barotrauma and dizziness. Divers should practice techniques like the Valsalva maneuver (pinching the nose and gently blowing to equalize ear pressure) or the Frenzel maneuver to maintain equal pressure between the inner ear and the surrounding environment.
• Ascend Slowly: Ascending too quickly can trigger vertigo and other complications, such as decompression sickness. It’s important to ascend slowly to allow the body to adjust to the changing pressure.

C. Controlled Movements

• Slow Movements: Sudden, jerky movements underwater can provoke dizziness or vertigo, particularly in individuals prone to vestibular issues. Perform slow and deliberate movements, especially when turning the head or changing direction.
• Avoiding Rapid Depth Changes: Avoid making rapid dives or sudden depth changes. Diving at a controlled, moderate pace reduces the likelihood of triggering vertigo and helps with pressure equalization.

D. Decompression Protocols

• Follow Diving Tables or Dive Computers: Ensure that you follow safe ascent protocols, including proper use of diving tables or dive computers. These tools help ensure that you ascend slowly and avoid decompression sickness, which can contribute to dizziness and vertigo.
• Decompression Stops: For deep dives, make the necessary decompression stops to allow your body to safely release nitrogen from the bloodstream. Failing to do so can lead to serious complications, including vertigo and neurological issues.

E. Hydration and Nutrition

• Stay Hydrated: Dehydration can worsen vertigo symptoms, so drink plenty of water before and after diving. Avoid alcohol, which can lead to dehydration and exacerbate dizziness.
• Eat Balanced Meals: Maintaining stable blood sugar levels is important to avoid dizziness. Eat a light, nutritious meal before diving, as low blood sugar can contribute to vertigo.

F. Breathing Techniques

• Regulated Breathing: Avoid hyperventilation, which can lead to lightheadedness or vertigo. Practice slow, deep, and controlled breathing throughout the dive. This ensures that your oxygen levels remain stable and reduces the chances of feeling dizzy.
• Relaxation: Stress and anxiety can contribute to vertigo and make it harder to maintain balance underwater. Keep calm and focused during the dive. If you start feeling unwell, signal your buddy and ascend slowly.

G. Equipment

• Well-Fitting Equipment: Ensure that your diving mask, regulator, and other equipment are fitted properly. An ill-fitting mask or regulator can cause discomfort and may contribute to dizziness or vertigo.
• Use of Stabilizing Devices: If needed, use stabilizing equipment such as a buoyancy control device (BCD) to help maintain stability and avoid disorientation.

4. When to Avoid Diving with Vertigo

For some individuals, vertigo may be a contraindication for diving. People with the following conditions should generally avoid underwater diving:

• Severe or Untreated Vestibular Disorders: Conditions like Meniere’s disease, labyrinthitis, or untreated BPPV may make diving unsafe due to the risk of sudden vertigo attacks.
• Uncontrolled Vertigo: If you are experiencing frequent or severe vertigo episodes, especially those that involve imbalance, nausea, or dizziness, diving may pose a significant safety risk.
• Recent Ear Surgery or Infections: Any recent ear surgery, ear infections, or injuries to the ear should be healed before considering diving, as they can exacerbate the risk of barotrauma and vertigo.

5. Signs of Vertigo or Dizziness While Diving

• Nausea or Vomiting: If you feel nauseous or start vomiting while diving, this could be a sign of vertigo or other medical issues. Ascend slowly and seek medical help if necessary.
• Confusion or Disorientation: If you begin to feel confused or disoriented during a dive, it could indicate a more serious problem like nitrogen narcosis or decompression sickness. Make sure to ascend slowly and immediately communicate with your dive buddy or instructor.

Conclusion

Vertigo during underwater diving is a complex issue that requires careful management and consideration of the various factors at play. Pressure changes, motion sickness, decompression sickness, and pre-existing vestibular conditions can all contribute to dizziness or vertigo in divers. To safely manage vertigo while diving, it’s crucial to follow proper equalization techniques, dive slowly, stay hydrated, and consult with medical professionals before diving if you have a history of balance disorders. If vertigo symptoms occur, it’s important to address them immediately by signaling your dive buddy and slowly ascending to the surface.
