The circulatory system of the human body is its lifeblood.
This is also very true for the human ear. The tiny, intricate inner ear system is actually an energy hog. It punches way above its weight (which is miniscule).
So, any overall issues with blood flow will negatively affect hearing.
And that’s why there is — regrettably — a link between diabetes and hearing loss. It’s now clear that the onset of the condition is also a risk factor for both short- and long-term development of hearing issues. In fact, it is currently calculated that diabetes doubles a person’s chances of developing hearing loss.
This is because the delivery of glucose — which is, in effect, how cells fill their gas tanks — is degraded by diabetes. Instead of it being normally transferred to cells, glucose builds up in the bloodstream. Cells become starved for energy, leading to a myriad of problems.
One of those difficulties is that the functioning of the ear’s many pieces declines.
And it’s not just a lack of direct energy transference that is the problem. Higher than normal levels of glucose also damage blood vessels over the long-term, meaning the issue the inner ear’s cells being malnourished is supplemented by the fact that the transfer mechanism — the circulatory system — is simultaneously being damaged.
This is yet another reason why diabetes should be taken extremely seriously and a physician’s advice on how to manage it followed methodically. A host of extreme problems — organ failure, blindness, amputation — can result from untreated diabetes.
Add hearing loss to that sad list.
