Compression garments

A simple, drug-free way to keep blood from pooling in the legs. Waist-high medical compression reduces the blood-flow drop that causes dizziness on standing, and it carries almost no risk.

Short version: medical-grade, waist-high compression keeps blood from pooling and eases standing symptoms. Low-risk and first-line; abdominal coverage matters more than calf-only.

Pushing blood back up

Compression garments squeeze the legs and abdomen so less blood pools below the waist on standing, reducing the drop in brain blood flow that drives dizziness.1

What standing up does Lying downheart rate about 72,blood spread evenly stand up Standingblood pools in the legs;to compensate the heartraces 30+ beats faster POTS = the racing heart on standing;orthostatic intolerance = dizzy, foggy, faint upright
Standing is a small cardiovascular stress test. Gravity pulls blood into the legs, and the body must tighten vessels and adjust heart rate to keep the brain supplied. When that reflex misfires, the heart compensates by racing (POTS) and the brain is briefly under-supplied, felt as dizziness, lightheadedness, and fog on standing.

What the evidence says

Reviews list compression among practical first-line measures, with abdominal and full-leg (waist-high) compression more effective than calf-only. Trial evidence is modest but the risk is essentially nil.2, 3

first-line, low-risk

Using it

Medical-grade waist-high compression, put on before getting up, tends to help most for POTS and orthostatic intolerance. It pairs naturally with fluids, salt, and paced activity.

What we don't know

Honest about the edges of the evidence. These are open questions, not settled answers.

  • The best garment strength and coverage, which is undertested.
  • How much it adds on top of fluids and salt.
  • Why tolerance varies.
