Lipedema/ Lipoedema (both spellings are used interchangeably) is a cronic disorder of the adipose tissue generally affecting the legs, and sometimes the arms, but not the feet, to accumulate fatty tissue. It occurs almost exclusively in women and is typically dismissed as simple obesity. If you have struggled with fat hips and legs and/or upper arms, and that fat would not go away despite diet and exercise, you may have lipoedema.
Believed to be hormonal in nature, lipoedema usually is triggered at puberty, but can appear during or after pregnancy, menopause, extreme stress, surgery or other trauma.
