The virus that shook the world has a few symptoms we all know, such as loss of taste and smell. And by now, most of us have heard of the term “long-COVID”, referring to recovered COVID-19 patients who have symptoms long after they test negative for the virus. Long-COVID symptoms include continued absence of smell and taste, difficulty breathing, fatigue, and brain fog. If you have been struggling with this, there is hope!
According to an early study funded by the National Institutes of Health, about 70% of COVID-19-positive patients had lost their sense of taste and smell. A later study found that 61% of recovered COVID patients still had symptoms after 6 months. That is a long time to go without being able to smell anything!
So why are so many people not able to smell for months after they had the virus? Loss of smell (anosmia) is actually a sign that the brain is inflamed.
What Causes Brain Inflammation?
Diabetes, obesity, and insulin resistance are risk factors for severe COVID-19. In fact, this whole-population study in England showed that one third of all the COVID-19-related deaths occurred in people with diabetes. That’s a huge percentage!
While it is known that these are risk factors for severe COVID, emerging evidence is also tying these to long-COVID, especially loss of smell and taste. As we mentioned before, the loss of smell and taste is actually related to brain inflammation. This can be caused by insulin resistance.
When you eat, your food is broken down into glucose (sugar) molecules. Your body then releases insulin, which is a hormone that allows glucose to enter a cell and be used for energy. When your cells become resistant to it, glucose can no longer enter and be used. This causes two things: your cells no longer have an energy source, and inflammation starts to accumulate.
Insulin is an important hormone for brain function. Insulin resistance causes your brain to not have enough energy to function properly and become inflamed. It has been tied to the loss of smell that is common in diabetes patients, so it is no wonder that it is also the culprit behind your long-COVID symptom. Insulin resistance is also one of the most common culprits behind autoimmune disorders and dementia.
Other symptoms of insulin resistance:
- Sugar cravings after meals
- Feeling “hangry” between meals
- Weight loss resistance
Insulin Resistance and Alzheimer’s
Your inability to smell or taste anything months after you had COVID-19 is an important sign that you may have insulin resistance that is causing your brain to become inflamed. This is important for you to get on top of not only so that you can enjoy your essential oil diffuser again, but also so that you can protect your brain from long-term damage.
Insulin resistance and diabetes have been linked to neurodegenerative diseases such as Alzheimer’s and other dementias for the same reasons they cause the loss of taste and smell. Over time, insulin resistance causes the brain to become more inflamed and receive less fuel for cell energy. Correcting insulin sensitivity levels can help you prevent, and sometimes even reverse, dementia.
