Lipedema or lipoedema is a chronic disorder of adipose tissue generally affecting the legs, which causes the legs and sometimes the arms to accumulate fatty tissue.[1] It is distinguishable by six characteristics:
it can be inherited;
it occurs almost exclusively in women;
it can occur in women of all sizes, from the seriously underweight to the morbidly obese;
it involves the excess deposit and expansion of fat cells in an unusual and particular pattern – bilateral, symmetrical and usually from the waist to a distinct line just above the ankles;
unlike normal fat, lipedematous fat generally cannot be lost through diet and exercise;
a pathognomonic indicator of lipedema is that the feet are spared.
Lipedema usually is triggered at puberty, but can trigger or worsen during or after pregnancy, at peri-menopause, and following gynecological surgery, i.e., surgery of the uterus, ovaries, or fallopian tubes or any surgery with general anesthesia. Lipedema can also be triggered by an extremely stressful situation such as a death in the family or a divorce because cortisol levels increase, causing an inflammation cascade, almost always misdiagnosed as simple weight gain. If lipedema is diagnosed early, which currently is very rare, it is possible to prevent a significant expansion of lipedematous fat cells and to alert patients to their heightened risk factors so they can take appropriate action.;
