Why does cystic fibrosis cause a person's sweat to be abnormally salty?

Extra loss: Cystic fibrosis is caused by a genetic mutation of cftr protein that moves chloride ions out of cells in respiratory tract, but into the cells in sweat gland ducts. Since cftr protein is not functional in CF pts, excess chloride gets secreted in their sweat, which causes the sweat to have higher salt concentration. That is why a sweat test measuring chloride is used as a diagnostic test for cf. ...Read more

I wouldn't: There is no relationship between Hirschprung disease and CF. If you wand to know if you are an asymptomatic carrier of CF, the tests are available. However, you don't get to age 30 without symptoms when you have the disease and your fertility would also be diminished.If your wife is not a carrier, you can not produce babies with CF. ...Read more
