What is the relation between cystic fibrosis and osmosis?

What is the relation between cystic fibrosis and osmosis?

Hmm: Besides both of them ending in -is, not much. But cystic fibrosis results from abnormal electrolyte movement across cell membranes in various organs of the body. Osmosis is a method of movement of molecules across membranes as well. ...Read more

How can cystic fibrosis affect p.I.E. S development?

Certainly: Cystic Fibrosis (CF) most common life-limiting genetic disorder of Caucasians, affecting approximately 30K people in the US. A, impacting mainly respiratory function. In recent years patients symptoms better controlled by genetic findings and better medications. Emotional & phys. Development depend on severity, time in hospital, complications. Morb. & mort.factors afect emotional, cognitive behavior. ...Read more

Can someone be diagnose with cystic fibrosis in their 40s?

Can someone be diagnose with cystic fibrosis in their 40s?

As a carrier: Genetic carrier testing:
more than 10 million americans are symptomless carriers of the defective CF gene. This blood test can help detect carriers, who could pass CF onto their children. To have cystic fibrosis, a child must inherit one copy of the defective CF gene from each parent. ...Read more

I have symptoms of cystic fibrosis. Is it possible to start show the symptoms in my 30s?

Yes: Yes it is possible. Presentation of cystic fibrosis varies greatly, and it is possible, depending on your specific mutation (and other factors) to present at a later age. In order to prevent late diagnoses, all states now have a newborn screen in place for cystic fibrosis. ...Read more

I have family members with cystic fibrosis. Is it possible to start show the symptoms in my 20s?

Yes: However, usually an adult who is diagnosed so late has usually had chronic problems with cough and "pneumonias". That said I've diagnosed a new case in a 38-year-old woman. ...Read more

What are the chances of a child getting cystic fibrosis among the different racial groups in the u.S.?

What are the chances of a child getting cystic fibrosis among the different racial groups in the u.S.?

Overall 1/3700: Acording to the CF foundation: the overall birth prevalence is 1/3700. It can occur in any race, however the greatest incidence is in caucasians of northern european descent, being 1/2500. The other major groups affected are hispanics 1/13500, african americans 1/15000.
More than 10 million of us carry one part of the defective gene, but to have the disease you must have a copy from both parents. ...Read more

What is cystic fibrosis?

Genetic disorder: It is a genetic disorder characterized by abnormal sodium channels, which affect a great deal of problems including the respiratory and digestive systems. It is most commonly diagnosed in infants failing to gain appropriate weight, and in children who have multiple chronic infections. ...Read more

What is cystic fibrosis exactly?

What is cystic fibrosis exactly?

Inherited disease: Cystic fibrosis (CF) is an inherited disease that affects the cells lining the lungs, sinuses, intestines, spleen and liver. It prevents chloride ions from crossing the cell membranes properly. This can clog organ ducts. In the lungs, the extra mucus crushes the cilia and leads to more lung infections. Medications can help; in late-stage disease, lung transplantation may be life-saving. ...Read more

What exactly is cystic fibrosis?

Cystic fibrosis: CF is a genetic disease that from birth causes the body to produce a thick and sticky mucus. This mucus interferes with the ability to breath and digest food. It is life threatening, but with good management people can live into their 40s and beyond with it. ...Read more

Cystic fibrosis, is it sexlinked?

Cystic fibrosis, is it sexlinked?

Autosomal recessive.: Cystic fibrosis (CF) is not sex-linked, but autosomal recessive. That means both parents can be silent carriers--totally unaware--then each passes down this recessive (inactive) gene to their child. This child develops CF because both copies of the formerly inactive gene (1 from each parent) now have no genetic "brake" (normal dominant gene) to prevent the CF gene from expressing itself. ...Read more

What is the severity of cystic fibrosis?

What is the severity of cystic fibrosis?

Variable: This depends on the individual patient. There are several hundred CF mutations that have varying degrees of severity. The most common mutation, df508, can cause failure to thrive in infants, recurrent and very serious lung infections during childhood and often pancreatic insufficiency in children. While early diagnosis and preventive treatment have improved, CF is still a fatal disease. ...Read more

In what way is cystic fibrosis inherited?

In what way is cystic fibrosis inherited?

CF is recessive: Cystic fibrosis is a disorder passed thru the genes of both parents, silent in the carrier parent & expressed in the affected kid who has inherited an affected gene from both parents. One mutation(delta 509) is the most common but others occur and variations in intensity do occur. I believe you can have carrier testing to see if u carry a gene, then avoid a starting a pregnancy with another carrier. ...Read more

Are there official recommendations for treating cystic fibrosis?

CF center: The usual suggestion for those with CF is to get treated at a CF center (a center accredited by the CF foundation) that has a multidisciplinary clinic. Nutrition, exercise, pulmonary toilet, and medications vary by age, lung function, and other problems and should be individualized. http://www.cff.org/livingwithcf/carecenternetwork/cffoundation-accreditedcarecenters/ can help you find one. ...Read more

What are the causes of differences in the severity of cystic fibrosis?

What are the causes of differences in the severity of cystic fibrosis?

Different mutations: Mutations in the cftr gene cause cystic fibrosis. The cftr gene provides instructions for making a channel that transports negatively charged particles called chloride ions into and out of cells. More than 1, 000 different mutations in the cftr gene have been identified in people with cystic fibrosis. Depending on the which mutations and other genetic factors, this leads to variability of disease. ...Read more

Is cystic fibrosis because of mucus?

Kind of...: Cystic fibrosis (CF) is a genetic disease. Patients with the disease are born with a defective gene that is part of the body's system for making mucus, sweat, and digestive fluids. Their mucus is therefore abnormally thick and causes blockages in the lungs, pancreas and other organs that damage them and make them prone to infections and other problems. ...Read more

Are cystic fibrosis and diabetes related?

In a way: Most patients with diabetes have either a failure of the pancrease (pancrelipase) to produce Insulin or develop resistance to Insulin for various reasons. In cf, there is pancreatic insufficiency due to injury to the pancrease (pancrelipase) from the disease itself... And this can lead to CF related diabetes (where more Insulin is needed). ...Read more

Why does cystic fibrosis shorten life span?

Why does cystic fibrosis shorten life span?

Chronic Illness: Progress in management has improved the quality of life for CF patients but it doesn't take away the basic vulnerabilities of the illness. In its worst forms, the illness shuts down production of enzymes that permit digestion of food & creates excessive mucous in the lungs that sets them up for deadly pneumonia & lung scaring. At some point, one of the complications will end their lives. ...Read more

Do people with cystic fibrosis have a lot of pain?

Cystic fibrosis: Patients with CF can suffer from sinus, respiratory, pancreatic, and biliary disease. They can also experience infertility, musculoskeletal disease, kidney stones, recurrent venous thrombosis, and small bowel obstruction. Obviously, some of these complications are associated with varying degrees of pain. It is probably more appropriate to ask about the overall morbidity of the disease. ...Read more

Why can't cystic fibrosis patient be near each other?
