With POTS, standing pulls blood down into the legs and abdomen, and the heart races to keep up. Graduated compression helps veins push that blood back up, which is why clinicians often recommend it as an early, non-drug measure. NursingRx knee-highs are 14-18 mmHg — light everyday support. Most POTS guidance favours firmer, waist-high compression, so treat these as a gentle option and check with your clinician.
In postural orthostatic tachycardia syndrome (POTS), standing lets blood settle in the legs and abdomen. Less blood returns to the heart, and the heart rate climbs to compensate — the dizziness, fatigue and racing pulse many people describe.
Graduated compression squeezes most at the foot and less further up, helping veins move blood back toward the heart. Clinical guidance lists compression garments among the first non-drug measures for orthostatic intolerance, alongside fluids, salt and exercise as advised by a clinician.
Studies of POTS and orthostatic intolerance show the biggest benefit from waist-high or abdominal compression, often 30-40 mmHg, because much of the pooling happens in the abdomen and thighs. Knee-highs alone tend to help less.
NursingRx knee-highs (18 mmHg foot, 16 mmHg ankle, 14 mmHg calf) are light everyday support. They can ease tired, heavy legs and suit people who cannot tolerate firmer garments, but they are not a substitute for the compression level a POTS clinician recommends.
Clinicians commonly suggest 20-30 mmHg or 30-40 mmHg, ideally waist-high or with an abdominal binder, because pooling occurs in the abdomen and thighs as well as the calves. Light 14-18 mmHg knee-highs offer gentler support and may be a starting point for comfort, but ask your clinician what level suits you.
They can help leg heaviness and mild swelling, but research suggests lower-leg compression alone has a smaller effect on POTS symptoms than compression that covers the thighs and abdomen. Many people combine knee-highs with an abdominal binder.
Put them on in the morning before getting up for long, while blood has not yet pooled, and wear them during the hours you are upright. Take them off at night unless a clinician advises otherwise.
No. Compression is one supportive measure. POTS management is individual and usually includes fluids, salt, graded exercise and sometimes medication under a clinician's care.
This page is general information, not medical advice. Get assessed before relying on compression if any of these apply:
Fainting, or near-fainting that is new or getting worse
Chest pain, shortness of breath or palpitations with exertion
Symptoms you have not had diagnosed — POTS needs a clinical assessment
Arterial disease, diabetic neuropathy or reduced sensation in the feet
Broken, fragile or ulcerated skin on the legs
Heart failure or any condition where a clinician has limited compression
