Cystic Fibrosis- Causes

Cystic Fibrosis, or Fibrocystic disease, is a mutation in a gene that a protein normally monitors the salts movement in and out of the cells. The gene is recessive and is located on the CFTR gene, or chromosome 7. Each parent must give their child the gene for Cystic Fibrosis or they will only be a carrier. Both males and females can give or receive this disease. It is a rare disease and everyone can get it, but mostly White Northern Europeans, Latinos, and Native Americans are prone to Cystic Fibrosis.

Cystic Fibrosis- Signs and symptoms

Cystic Fibrosis symptoms usually depend on how bad the disease is. If you have Cystic Fibrosis, you will most likely notice the signs at a young age, but some do not experience this until later on. Symptoms for this disease effect several things, including the respiratory system, digestive system, growth, and the reproductive system. These are very noticeable symptoms, as they include frequent coughing up of mucus, wheezing, hard to breathe making it difficult to exercise, many lung and sinus infections and stuffy noses. Other symptoms include little weight gain and growth and severe constipation.

Cystic Fibrosis- Treatments

A child at birth will always be tested for Cystic Fibrosis. If they happen to have the disease, the child will receive treatment right away. No cures exist for Cystic Fibrosis, but there are plenty of treatment options. People with the disease have to follow a regular treatment routine in order to keep lung health, receive good amounts of nutrition and keep growth levels normal. Thick mucus builds up in the lungs and airways, so a daily clearing is needed for normal breathing. This includes taking antibiotics and supplements. The affects of Cystic Fibrosis vary for each patient. For most, the disease gets worse overtime, but for others, it can get better. Sometimes you won't have as many symptoms, but at other times you will have a lot of symptoms. There are other treatments such as an Inflatable vest and breathing devices to help with breathing.

Cystic Fibrosis- Life with this disease

Although you can't completely get rid of your symptoms from Cystic Fibrosis, there are plenty of ways to stay healthy and experience less symptoms. People with this disease can't get the nutrients needed because the enzymes needed to digest food cannot get to the small intestine. This means that they will need 50% more calories than most normal people need to have. Other things that will help out are supplemental high calorie nutrition, extra fiber, and a higher intake of salt. Drinking lots of water and exercising daily can also severely reduce the symptoms and keep you feeling healthy. Since Cystic Fibrosis clogs up your reproductive organs with mucus, you will not be able to have kids without surgeries.

Cystic Fibrosis- Complications

This disease can cause many other complications that just the usual symptoms. With the respiratory system, you can get Bronchitis, Chronic infections, coughing up blood, and respiratory failure. The digestive system can also receive problems, like Diabetes and a blocked bile duct. Men with this disease are almost always infertile, so they cannot have children unless surgical procedures take place. Osteoporosis and Electrolyte imbalances are other problems that can occur. Most of these complications can be prevented with special care and treatment.
