Blackfoot
Blackfoot Disease
Blackfoot disease (pronunciation: /ˈblækˌfʊt diːˈziːz/) is a severe form of peripheral arterial disease (PAD) that was endemic among the native population of Taiwan in the early to mid-20th century. The disease is named after the characteristic black discoloration of the feet of those affected.
Etymology
The term "Blackfoot" is a direct translation of the Chinese term "黑脚病" (hēi jiǎo bìng), which describes the black discoloration of the feet in advanced stages of the disease. The disease was named by the local population of Taiwan, where it was endemic.
Symptoms
The primary symptom of Blackfoot disease is gangrene in the lower extremities, leading to the characteristic black discoloration of the feet. Other symptoms include pain in the legs and feet, numbness, and difficulty walking.
Causes
Blackfoot disease is caused by chronic exposure to arsenic in drinking water. The disease was particularly prevalent in areas of Taiwan where the groundwater contained high levels of arsenic.
Treatment
Treatment for Blackfoot disease involves removing the source of arsenic exposure and managing the symptoms of the disease. In severe cases, amputation of the affected limb may be necessary.
