Wondering if POTS is the name of what my post-COVID brother is suffering from
postural orthostatic tachycardia syndrome, or POTS, was coined in 1993 by Dr. Phillip Low and his team at the Mayo Clinic, though it went by other names throughout history. POTS precludes standing for more than a few minutes at a time, because autonomic damage prevents blood vessels in the lower extremities from properly returning blood to the heart and brain against gravity. Heart rate can double or triple on standing, and lack of oxygen to the brain and upper body lead to many of the symptoms seen in POTS patients: dizziness, headaches, shortness of breath, chest pain, “brain fog.”
If a POTS patient does stay vertical for a prolonged period, he or she can be left with massive fatigue, light and sound sensitivity, tingling extremities, temperature intolerance and gastrointestinal problems (again, all the bodily functions of the autonomic nervous system gone awry).
