Origin of the name/history of the disease
The name celiac comes from "coeliac" which is derived from the Greek Koilia, which means belly. The "coeliac flux" is an old expression meaning the same as diarrhea. The disease celiac is not just diarrhea though it just means that the disease pertains to the abdomen.
The celiac disease comes from early farmers and hunters. But because the wheat and grain of the crops and fields did not have high levels of gluten they were not exposed to the disease very often. Those who were infected would contract other diseases due to excessive defense. The disease did not hit hard until industrial quantities of gluten were introduced. The disease usually affects children at birth so you would think the disease would just die off. Wrong. The hinters and farmers developed an excessive defense to the disease. The defense would focus on the disease, which would make the person affected susceptible to other viruses. Also, breast-feeding preserves some children from the disease. The antibodies from the milk help fight the infections.
Loci of the gene/populations at risk/how common
Celiac has been mapped to the major histocompatibillity on chromosome 6.
Celiac mostly affects people of European descent and rarely affects blacks or Asians. It affects infants and can kill them at birth due to infections, malnutrition, and malabsorption. Those affected suffer damage to the villi in certain regions of the intestines. Sometimes the disease becomes triggered after surgery, pregnancy, childbirth, v infection or severe emotional stress. The longer someone was breastfed the later the symptoms appear.
Celiac is the most common disease in Europe. In Italy 1 in 250 people have celiac and in Ireland about 1 in 300 people have it. About 1 in 4,700 people in America have Celiac. This is uncommon since Americans are descendants of Europeans. Red Cross had a recent study in which they took random blood samples and tested them for Celiac....
