How can we help?
Cystic fibrosis (CF) [SIS-tic fye-BRO-sis] is a genetic disease, which means a disease that is inherited, or passed from parents to a child. Most of the time, CF affects the mucus [MEW-kuhs] lining in your liver, intestines, lungs, pancreas, sinuses, and sex organs. CF affects your mucus and sweat glands, making your mucus thick and sticky.
Mucus helps protect the body. Healthy mucus is usually slippery, but slightly thicker than water.
In people who have CF, their mucus can become so thick that it clogs the lungs, making it hard to breathe. People that have CF can also have frequent lung infections, which can cause lung damage.
The thick mucus can also block the tubes in your pancreas, which prevents enzymes from getting to your intestines, making it difficult to absorb nutrients such as fats and proteins from the food that you eat.
Although it can affect a few different organs, the thick mucus that CF creates usually has the biggest effects on how you breathe and digest food.
Symptoms can be very different from person to person. Sometimes symptoms show up at birth, and sometimes they show up later. Also, in some cases, you may have few symptoms, or very mild symptoms when you are younger, but get more or worse symptoms when you get older. Sometimes you may have few symptoms, and other times your symptoms may be more severe.
If CF is developed from birth, some of the first symptoms of CF include:
Respiratory symptoms may include:
Digestive symptoms may include:
Reproductive symptoms may include:
CF may also cause clubbing, which is when the tips of the fingers become wider and rounder as the lungs are not moving enough oxygen into your bloodstream due to the mucus blockages. Clubbing usually develops later in life.
CF may also cause >low bone density, which could lead to osteoporosis or other bone problems.
Other signs and symptoms of CF are generally due to an imbalance of nutrients and minerals in the blood. CF causes your sweat to become very salty, which causes you to lose a lot of salt when you sweat. You may become dehydrated more easily than other people.
It is important for you to see a doctor if you suspect you have CF so that you can begin treatment as soon as possible. It is important to start treatment as soon as possible because CF can have serious complications, and may also develop into, or cause, more severe conditions such as:
CF is an inherited disease, which means it is passed from parents to a child. Even if you do not have the symptoms of CF, or have been diagnosed with CF, you can still be a carrier for the disease and pass CF on to your child.
You can get tested to find out if you have the genes that cause CF, which may help as you think about having children. If you and your partner are both carriers of CF, it is more likely that your children will have CF.
If you and your partner both have CF, your child will have CF. There are two types of tests that can help you find out if you are a carrier of CF, both of which are safe to take during pregnancy.
To find out if you are a carrier of CF, your doctor can:
There are many different ways to test for CF. These tests include:
Monitoring tests
If you test positive for CF, you doctor may order other tests to monitor the progression of the illness. These other tests may include:
Although there is no cure for CF, there are many different treatments to help ease your symptoms, depending on the severity of your CF.
It is important to catch CF as early as possible so that you can begin treatment early.
