Can you tell me how noticable is the salty skin with cystic fibrosis?

Can you tell me how noticable is the salty skin with cystic fibrosis?

Not a reliable sign: Salty taste on kissing is one of the features of cystic fibrosis (CF) due to excess salt loss in sweat of CF patients. The chloride content of sweat is used as a diagnostic test for confirming the diagnosis of cf, but tasting the saltiness of skin is not reliable by itself. If there is a concern about cf, please contact your nearest CF center for an evaluation & sweat test. ...Read more

How noticeable is the salty skin that people get with cystic fibrosis?

Depends on Severity: This would depend on the severity of the disease state in the individual, but by and large, it's enough of a difference from "normal" sweat to make one take notice. Clinically, the sweat chloride level is measured twice to make the diagnosis of cystic fibrosis (cf). The cutoff level to make the diagnosis of CF is 60 milliequivalents per liter of sweat chloride. ...Read more

Is there a reason having cystic fibrosis makes your skin salty?

Is there a reason having cystic fibrosis makes your skin salty?

Chloride channel...: The genetic defect that causes cystic fibrosis (CF) interferes with the body’s ability to move salt in and out of cells. The salt that cannot be absorbed is excreted through the skin by the sweat glands, resulting in salty sweat. Sometimes, there may even be visible salt deposits on the skin. Salt excretion by the sweat glands is the basis of the most common test used to diagnose cf. ...Read more

How can you expect life to bevfor a person with cystic fibrosis after a lung transplant?

How can you expect life to bevfor a person with cystic fibrosis after a lung transplant?

Varies: Not everyone has a similar experience post lung transplant. In general, respiratory symptoms and breathing, overall improve, and people are able to do activities they were not able to do before as easily. Not all respiratory symptoms go away. Various medications are required and close follow up is mandatory. Survival after lung transplantation is ~ 50% at 5 years. ...Read more

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

When will the symptoms appear in a person who is affected of cystic fibrosis?

Varies: Newborns can present with bowel obstruction from lthickened meconium , early stool, from lack of normal enzymes.Sometimes bowel atresia and twisted bowel in utero are other manifestations. In child, respiratory symptoms may result with over aeration and asthmatic symptoms from mucus plugging in lungs. Malabsorption, fatty liver, and anemia in early childhood. Some mild forms do not show until later. ...Read more

Why could cystic fibrosis cause a person to be malnourished?

Pancreatic insuffic: The pancrease (pancrelipase) is the organ that (among other things) secretes enzymes that help the body absorb fat. In CF the pancrease (pancrelipase) can become clogged and fail to do this... So the patient needs to take enzymes orally. Additionally, when the lungs are injured enough, cfers will start having a lack of appetite as well, the cause of this is less clear. ...Read more

Is it possible for a person to have a "minor" form of cystic fibrosis so-to-speak? And if yes, how would it manifest?

Yes: I would rather use a term "mild" or "atypical" instead of minor form of cystic fibrosis. Cystic fibrosis is caused by mutation involving cftr gene, and there are a few hundred different mutations. Atypical or mild form of CF manifest at a later age than in infancy as often seen in classic form, and mild in symptoms. ...Read more

What happens if there is an intrapulmonary shunt or the person has cystic fibrosis, can they survive on a ventilator?

What happens if there is an intrapulmonary shunt or the person has cystic fibrosis, can they survive on a ventilator?

Yes: Shunts and CF do not preclude survival on a ventilator. It may be more difficult to clear secretions from CF on ventilator but can be done ...Read more
