The lipedema pinch test
The pinch test means pressing or pinching a fold of tissue to see whether it hurts. Lipedema tissue is usually painful under pressure and ordinary fat is not, which makes it a useful signal. It is one sign among several, it is not a diagnosis, and a negative result does not rule lipedema out.
What it is checking
Tenderness. Tenderness is one of the features that can separate lipedema tissue from ordinary body fat, and in the US Standard of Care 80% of women with lipedema rate their pain at 5 or above out of 10, spontaneously and on pressure. That is not true of ordinary fat, and it is not true of cellulite, which is why the question "does it hurt when you press it" carries so much weight in a short appointment.
Why it is not a diagnosis
Pain has other causes, tenderness varies across the same limb, and pressing a less affected area can produce nothing at all. Clinicians read it alongside the other signs, and no single one of them is decisive on its own.
| Sign | What it points to |
|---|---|
| Tenderness on pressure | Lipedema tissue rather than ordinary fat |
| Symmetry, both limbs | Lipedema rather than lymphedema or a venous cause |
| Feet and hands spared | Lipedema rather than lymphedema |
| Bruising with no injury | Capillary fragility typical of lipedema |
| Disproportion that persists after weight loss | Lipedema rather than ordinary weight gain |
The Stemmer sign, which is a different test
The Stemmer sign asks whether you can lift a fold of skin at the base of the second toe or finger. If you cannot, that is a positive Stemmer and points toward lymphedema. Lipedema typically spares the feet, so Stemmer is usually negative in lipedema alone and can turn positive if a lymphatic component develops. The two tests are often confused because both involve pinching. How the two conditions differ.
What to do with the result
Treat it as one line of your history. Write down where it hurts, how much, and whether it is both sides, and bring that with you. The ten-question self-check covers the full set of signs, and how to get diagnosed covers who can confirm it.

Common questions
What is the lipedema pinch test?
Pinching or firmly pressing a fold of tissue on the affected limb to see whether it hurts. Lipedema tissue is characteristically tender or painful under pressure, while ordinary fat is not. Clinicians use it alongside other signs rather than on its own.
Does a positive pinch test mean I have lipedema?
No. It means the tissue is tender, which is one of several signs clinicians weigh together with symmetry, easy bruising, sparing of the feet, disproportion, and how the tissue responds to weight loss. Tenderness has other causes, and only a clinician can diagnose lipedema.
Can the pinch test be negative if I do have lipedema?
Yes. Pain varies between people and across the same limb, and pressing a less affected area can produce nothing. A negative result does not rule lipedema out, which is why it is never used alone.
What is the difference between the pinch test and Stemmer sign?
They test different things. The pinch test looks for tenderness in the fat tissue. The Stemmer sign checks whether you can lift a fold of skin at the base of the second toe or finger, and a positive Stemmer, meaning you cannot, points toward lymphedema. Lipedema typically spares the feet, so Stemmer is usually negative unless a lymphatic component has developed.
