The national disease: medical geography
Medical geography - a special branch of medicine that deals with the study of diseases in connection with the nationality and place of residence of the patient.

Some diseases are found only in people of a certain nationality or, in some regions - the so-called endemic diseases.

national disease may be associated with a genetic predisposition, or with the diet and lifestyle of some people.

Hereditary national disease

Genetic diseases associated with disturbances in the genome of the cells and are inherited.In many cultures there are defects in the genes that cause the appearance of specific diseases typical of people of the same nationality.

There is a racial predisposition to certain diseases, such as black people often suffer from hypertension, which flows from them harder than whites.

In Asia, where the main food was polished rice, met vitamin B1 vitamin deficiencies (beriberi disease) and related neurological disorders.National disease

Asian peoples can be considered and esophageal cancer - because of the tradition of eating overly spicy and hot food in the East it is diagnosed more often than in other regions.

In Russia, from genetic abnormalities are common cystic fibrosis, phenylketonuria, spinal amyotrophy and sensorineural hearing loss.

Chuvashia born many children with congenital osteoporosis, and in Mari El and Udmurtia - with ichthyosis (generalized violation of keratinization of the skin).
