Orthostatic Intolerance: Non-Drug Management
Peter Rowe, MD, of Johns Hopkins, first described the link between ME/CFS and orthostatic intolerance (OI): symptoms triggered or worsened by standing. His non-drug management approach layers fluid loading (roughly 2 to 3 liters a day), sodium loading (roughly 3 to 10 grams a day, physician-guided especially at the higher end), compression garments, and counter-maneuvers (leg crossing, calf raises, tensing muscles before and during standing). Any reconditioning happens only within a person's pacing envelope, never as graded exercise therapy or a push-through program. This is informational, alongside your physician's care.
Increase daily fluid intake to roughly 2 to 3 liters a day, spread through the day 2-3 L/day; confirm with your clinician, especially with kidney or heart disease
Higher fluid intake increases effective circulating blood volume, directly addressing one driver of orthostatic symptoms.
Increase dietary sodium, commonly in the 3 to 10 gram a day range depending on severity and physician guidance 3-10 g/day; the higher end specifically needs physician guidance, and this does not apply if you have hypertension, kidney disease, or the hyperadrenergic POTS subtype
Sodium loading helps the body retain the added fluid, compounding the blood-volume benefit above.
Wear waist-high or at minimum thigh-high compression garments 20-30 mmHg, waist-high preferred
Compression reduces blood pooling in the legs and abdomen on standing, directly countering the mechanism behind orthostatic symptoms.
Cross your legs, do calf raises, or tense your leg and abdominal muscles before and during standing or prolonged upright activity As needed whenever standing or upright for extended periods
Physical counter-maneuvers mechanically push blood back toward the heart and can blunt an orthostatic symptom spike in the moment.
If considering any gradual activity increase, do it only within your existing pacing envelope, never as a fixed, escalating exercise program n/a
ME/CFS is defined by post-exertional malaise. Rowe's own framework is explicit that reconditioning is not graded exercise therapy; pushing past your energy envelope is what triggers a PEM crash, not what fixes OI.
Rowe's research established that a large share of people with ME/CFS also have measurable orthostatic intolerance, meaning symptoms like lightheadedness, brain fog and fatigue worsen specifically with standing or being upright.

Is this for you
- People with ME/CFS who also feel worse standing or upright
- Anyone with a POTS/OI diagnosis alongside ME/CFS or long COVID
- Readers whose current care has not addressed the orthostatic component
Cautions
- Informational only, alongside your physician's care
- The higher end of sodium loading needs physician guidance; not appropriate for everyone
- Never graded exercise therapy or push-through; pacing always comes first with ME/CFS or PEM
