Ringing in the ears, or tinnitus, often isn't an ear problem but rather a brain issue where the brain produces sound to compensate for lost hearing at specific pitches. While loud noises and medication side effects can cause nerve damage, a significant factor often overlooked is chronic blood sugar elevation.
Chronic blood sugar elevation slowly damages the tiny blood vessels that supply the delicate nerves in the inner ear. These inner ear nerves are peripheral nerves, similar to those affected by diabetic peripheral neuropathy. High insulin levels can destroy the nervous system and lead to insulin resistance, starving the super-hungry nerves in the inner ear of fuel. Studies dating back to 2004 show a strong correlation between high insulin levels or pre-diabetic conditions and tinnitus.
Many people have reported significant improvement in their tinnitus by adopting intermittent fasting, low-carb, or ketogenic diets. These dietary changes help lower insulin levels, which in turn improves the fuel supply to the nervous system in the inner ear. Monitoring fasting insulin levels (aiming for below seven) is crucial, as normal blood glucose doesn't always reflect underlying insulin issues. Lowering blood glucose and insulin directly addresses the metabolic problem contributing to tinnitus.
While dietary changes address the root cause, two key nutrients can aid in nerve healing: Alpha-lipoic acid (600 mg daily for two months shown to significantly reduce ringing) and Benfotiamine (a form of vitamin B1 used for peripheral neuropathy). These nutrients work best in conjunction with diet changes to avoid recurrence of symptoms. It's recommended to take the standard dose of benfotiamine multiplied by four, spread throughout the day.
Results may vary depending on the severity and duration of tinnitus, but many should see improvements within seven days. Rating the intensity of tinnitus daily can help track progress. Tinnitus may be more noticeable at night due to how the body regulates fuel. Transitioning to burning fat for energy (ketones) by reducing carbohydrates can speed up results. Tinnitus is not necessarily permanent; consistent dietary changes and nutrient support can lead to significant improvement or resolution. Exploring prolonged fasting can further accelerate the process.
