My 39-year-old client Jennifer arrived about a year ago complaining about fatigue, joint pain, depression, and brain fog. Despite being incredibly healthy (Jennifer was a former competitive athlete who ate well and still exercised regularly), her primary physician had diagnosed her with lupus—an autoimmune disease where your immune system mistakenly attacks healthy tissue. She came to me convinced something more was going on, and indeed, a blood test revealed that Jennifer also had Epstein–Barr virus (EBV) and the gut-centered Helicobacter pylori (H. pylori).
