They are also known to decrease capillary fragility.

It results from occlusion of dermal capillaries by fat, and increased capillary fragility.

The Hess test or Rumpel-Leede test is a medical test used to assess capillary fragility.

Adverse effects include neuropsychiatric syndromes, gastrointestinal disturbances, proximal myopathy, hyperglycemia, aseptic necrosis, capillary fragility, and immunosuppression.

Interfering factors with this test are women who are premenstrual, postmenstrual and not taking hormones, or those with sun damaged skin, since all will have increased capillary fragility.

A tourniquet test (also known as a Rumpel-Leede Capillary-Fragility Test or simply a capillary fragility test) determines capillary fragility.
