Does Lack Of B12 Affect Your Hearing?

I asked Google AI, the title of this post and received this answer.

Yes, a lack of vitamin B12 can affect your hearing, potentially leading to tinnitus (ringing in the ears) and hearing loss. Deficiencies can cause nerve damage (demyelination) in the auditory nerve and damage the small blood vessels in the inner ear.

Impact on Hearing

Tinnitus: Studies suggest B12 deficiency is linked to tinnitus, with some research indicating that supplementation can improve or reverse these symptoms.

Hearing Loss: Low B12 levels are associated with a higher prevalence of hearing impairment, particularly in older adults.

Inner Ear Damage: A lack of B12 may cause degeneration of the cochlear nerve.

Developmental Issues: In children, B12 deficiency may interfere with auditory development.

Causes and Risk Factors

Deficiency can result in high homocysteine levels, which may impair blood flow to the cochlea.

Risk factors for low B12 include:

Vegetarians/Vegans: Due to limited dietary intake.

Adults Over 60: Due to reduced absorption.

Digestive Disorders: Conditions like Coeliac or Crohn’s disease.

Medications: Long-term use of metformin or antacids.

If you are experiencing persistent tinnitus or hearing changes, it is recommended to consult a doctor to check your B12 levels.

I fairly sure that my hearing fits that pattern. Although, I’ve never had tinnitus.

Can B12 Injections Improve Eyesight?

i had one of my three-monthly B12 injections today and my eyesight seems better.

So I asked Google AI, the title of this post and received this answer.

Yes, B12 injections can improve eyesight if vision problems are caused by a vitamin B12 deficiency. Injections can help reverse vision loss associated with B12 deficiency, such as in cases of optic neuropathy. They may also help lower the risk of developing age-related macular degeneration, though this is linked to maintaining sufficient vitamin levels rather than treating existing vision loss.

Note that when I typed the question into Google, Google appeared to predict I might type it.

As my hearing seems better, whilst, I’m watching  the television, I repeated the question with hearing and received this answer.

B12 injections may improve hearing for individuals with a B12 deficiency, particularly those with tinnitus, because low levels can damage nerves in the ear. For people without a deficiency, evidence suggests B12 injections have little to no effect on hearing. Studies show that B12 supplementation can reduce the severity of tinnitus in those who are deficient.

I shall keep having the injections.
