Mary was diagnosed with Lupus and she was able to manage it through a combination of medicine and healthy lifestyle. “Acupuncture has helped me manage the pain, and Yoga keeps me flexible,” she shared in one of her interviews. “Being physically active also helps to fight the fatigue associated with symptoms of lupus, so I try to work out daily on an elliptical machine and treadmill.”
In addition, she made changes on her diet practices. “I’ve also learned that certain foods can make my symptoms worse, so I avoid alfalfa sprouts and bell peppers, and eat a primarily gluten-free diet, since that reduces the symptoms of lupus,” she explained.
