As we age, hearing loss can become a common occurrence, especially if we’re exposed to loud noises frequently. Working in a noisy environment without ear protection, like a factory floor, can also contribute to future hearing loss. These are well-known causes. However, there’s a new contender in the mix that you might have already guessed: Covid-19.
Yes, the same virus that has turned our lives upside down in recent years might also have a connection to hearing loss. But let’s be clear: We’re still in the early stages of understanding Covid-19’s impact fully. New insights about the virus are constantly emerging from ongoing scientific research. While some studies suggest a potential link between Covid-19 and hearing loss, this research is still preliminary and requires further confirmation. So, let’s delve into the current state of knowledge.
Can Covid-19 Really Cause Hearing Loss?
First and foremost, let’s debunk a common misconception: There is absolutely no evidence that Covid-19 vaccines cause hearing loss. This holds true for all authorized vaccines, whether it’s Pfizer, Moderna, or Novovax. These vaccines don’t affect your ears in any way. It’s akin to blaming a nutritious salad for causing diabetes.
This principle applies to both traditional vaccines and the new mRNA vaccines. The benefits of these vaccines far outweigh any potential risks for most individuals. If you have concerns about vaccines, consult your doctor and seek information from credible sources.
With that cleared up, let’s focus on the topic of hearing loss.
How Could Covid-19 Lead to Hearing Loss?
So, how could Covid-19 potentially cause hearing loss, specifically sensorineural hearing loss, which results from damage to the auditory system and is usually irreversible?
There are a couple of theories, and either one, or perhaps both, could be contributing factors.
Theory #1: Inflammation
Covid-19 triggers inflammation in your upper respiratory tract, which could impact your ears as well. After all, your nose, mouth, and ears are interconnected. Inflammation might lead to hearing loss through:
Fluid Buildup: Inflammation can narrow drainage pathways, making it harder for fluids to escape efficiently. Accumulated fluid can hinder your ability to hear. Typically, your hearing returns to normal after symptoms subside, which wouldn’t qualify as sensorineural hearing loss.
Cell Damage: Remember that viruses replicate by hijacking your body’s cells, resulting in damage. Given that Covid-19 affects your vascular system, damage to the vascular connections between your ears and brain can occur. This type of damage would be considered sensorineural hearing loss and might be permanent.
For inflammation-induced hearing loss, steroids are often effective. Researchers are still exploring ways to prevent sensorineural hearing loss. While the extent to which vaccines protect against this type of hearing loss isn’t entirely clear, any level of protection is better than none.
Theory #2: Long Covid
The second theory, though less understood in terms of cause and effect, is more substantial based on patient experiences. You’ve likely heard about Long Covid by now—where symptoms linger long after recovering from the virus itself.
People with Long Covid continue to experience Covid-related symptoms, often debilitating, for months or even longer after the initial infection. The exact cause of Long Covid remains unclear but it’s a recognized phenomenon.
In February 2021, a systematic review examined data on long-term auditory complications resulting from Covid-19. Here are the findings:
- 7.2% reported vertigo
- Tinnitus was reported by 14.8%
- 7.6% experienced hearing loss after contracting Covid-19
There’s indeed a connection between Long Covid and hearing issues, though the direct cause and effect relationship is yet to be established. Various symptoms, including hearing problems, are associated with Long Covid.
Facts vs. Anecdotes
When someone shares a personal experience of contracting Covid-19 and subsequently facing hearing loss, that’s an anecdote. It’s a single individual’s account. While their reality is undeniable, it might not be sufficient for scientists to form treatment strategies. This is why research is critical.
The more information researchers gather, the clearer the picture becomes regarding Covid-19’s potential risks, including hearing loss.
However, there’s much more to uncover. The link between Covid-19 and hearing loss is neither confirmed nor refuted at this stage; ongoing research is essential. Regardless of the cause, if you’re experiencing hearing loss, seeking help promptly is crucial. If you suspect you’re dealing with hearing loss, don’t hesitate to reach out to us.
