Kelsy Clark

Kelsy Clark is a writer and creator sharing practical resources and honest perspectives on life with chronic illness. Living with POTS, MCAS, hypermobility, and fibromyalgia, Kelsy creates the books and tools she wishes she had when first diagnosed, helping others understand, track, explain, and navigate their experiences. Her books include Living with POTS, Nobody Told My Coach, and The Ultimate POTS Workbook. Visitors can also find a practical POTS guide, printable symptom tracker, and Notion management dashboard.

Alongside writing, Kelsy makes videos and shares reflections on everyday life, training, appointments, and learning to live well with chronic illness. She offers six weeks of one-to-one POTS support, grounded in lived experience rather than medical advice, and creates Chronic Illness Club apparel, including hoodies and T-shirts. Her site also features updates on training for the Philadelphia Half Marathon with Team Uplifting Athletes, recommended products, and occasional emails with new resources and personal insights.
