This Web site provides information and support to people  living with Hemihypertrophy and Hemihyperplasia (the overgrowth of one side of the body or part of the body), as well as those affected by Hemihypotrophy and Hemihypoplasia (the undergrowth of one side of the body or part of the body).

What is Hemi?  Hemihypertrophy, and Hemihyperplasia are often referred to as “Hemi” for short.  The terms refer to a medical condition in which one half of the body grows faster than the other half, causing a greater than normal asymmetry between the right and left sides of the body.  This difference can be in just one finger; just one limb; just the face; or an entire half of the body, including half the brain, half the tongue and the internal organs, or any variation in between. The skin is often thicker, and there may be more hair on the head, on the larger side.

Hemihyperplasia can occur as an independent condition without an identified syndrome, in which case it is referred to as Isolated Hemihyperplasia (this term is seen more in the United States) or Idiopathic Hemihyperplasia (this term is seen more outside of the United States).

Hemi is thought to occur in about 1 in 14,000 people. Isolated Hemihypertrophy occurs in about one in 86,000 live births. Females and males are affected equally.

Hemihypotrophy and Hemihypoplasia are the opposite of Hemihypertrophy and Hemihyperplasia.
