'Fatigue is one of the most common problems I see in my primary care clinic. Many of those with autoimmune diseases struggle with it every day, but even people who don’t suffer from a chronic disease often complain of fatigue, relying on caffeine to get them through the afternoon.
What people don’t often realize is that fatigue may be related to more than sleep deprivation. In my experience, it’s often a symptom of depleted and starved mitochondria. The reason for depleted and starved mitochondria is frequently an insufficiently nutrient-dense diet, exacerbated by the nutrient-depleting effects of medication.
In other words, the medication you take, along with your dietary choices, can be what is actually keeping you exhausted.'
