Uneven weight loss - is this lipedema? (Photo)

Lipedema is usually symmetric. Which means it affects both sides of the body equally. It usually starts in the legs and it usually only affects the trunk when all the body has been affected by the disease. The are other fatty [subcutaneous adipose tissue] diseases that affect the trunk and can be asymmetric. I recommend you consult with a fat disease specialist at your local university.

All people have significant asymmetry of their body.
Asymmetry, primarily based on bone structure and soft tissue layers tend to be more symmetrical.
Still most people will have significant difference in size of one side of the body compared to the other.
