The Study of Dwarfism

The reason i chose to study Dwarfism is i find the subject very interesting. To know that someone can be 20-30 years old and only be 4 feet tall really astonishes me when you think about the human body being able to survive at that size.

The Definition of Dwarfism

Dwarfism is generally defined as an adult with the height being 4 ft tall or less. There are two types of Dwarfism. Disproportionate Dwarfism which is when the body is small but other parts of the body are average to others or can even be bigger then average size people. Diseases causing this form of Dwarfism inhibit the development of bones. The other category or type of Dwarfism is known as Proportionate Dwarfism. This type of Dwarfism is when all the body parts are the same size in proportion with the rest of the body. signs are noticed at a young age and stunts growth and development.

Body affected by Dwarfism

The arms and legs are short. The head of a person with dwarfism looks to big for the body. Then some dwarfs have proportionate body parts. so those body parts do not look too big or to small compared to the rest of their body.

What causes Dwarfism?

Dwarfism can be caused by any of more than 200 conditions. Causes of proportionate dwarfism include metabolic and hormonal disorders such as growth hormone deficiency. The most common types of dwarfism known as skeletal dysplasias, are genetic. Dwarfism is a mutation on the 4th chromosome.

How the disorder is treated.

Some of the treatments are ....Insertion of a shunt to drain excess fluid and relieve pressure on the brain.A tracheotomy to improve breathing through small airways.Corrective surgeries for deformities such as cleft palate, club foot, or bowed legs. Surgery to remove tonsils or adenoids to improve breathing problems related to large tonsils, small facial structures, and/or a small chest. Surgery to widen the spinal canal to relieve spinal cord compression.

How the disorder is diagnosed.

The height of the child. Hormone test and appearance are the big test done, along with head circumference and family history charts.

How many and what type of people are likely to have the disorder.

it affects about 1 out of 26000 to 40000 thousand people. It doesn't have anything to do with location and it is a pretty rare disease.

New information that i learned

I learned that a couple with dwarfism have a chance at having a kid of normal height. I also learned that there were treatments for Dwarfism.
