Some of this variability has to do with genetics (the unique set of variations in your DNA) and epigenetics (how your lifestyle and environment influence the expression of your genes). Some of it has to do with the balance and diversity of your gut bacteria, the regulation of your immune system, the fluctuations in your hormones, and your level of inflammation at any given moment. In fact, what causes inflammation in you may be completely different from what causes inflammation in someone else, and how inflammation affects your health and functioning is also unique.
