Local gigantism

Local gigantism is when a part of your body grows a lot more than it normally should. Imagine if one of your fingers grew really, really big and looked like a giant finger compared to your other fingers.

This can happen if there is a problem with the way your body is growing and developing. Sometimes, a part of your body can start to grow too much because of a problem with your genes, which are like instructions for how your body should grow. Other times, an injury or a problem with your hormones can cause local gigantism.

Local gigantism can cause problems for the person who has it. For example, if your foot grew much bigger than your other foot, you might have trouble finding shoes that fit. You might also have trouble walking or running.

Doctors can help people with local gigantism. They might give them medicine to help control their hormones or they might do surgery to remove the part of the body that is growing too much.
