What Is Cystic Fibrosis?

*Cystic fibrosis (SIS-tik fi-BRO-sis), or CF, is an inherited disease of the secretory (see-KREH-tor-ee) glands. Secretory glands include glands that make mucus and sweat.

"Inherited" means the disease is passed from parents to children through genes. People who have CF inherit two faulty genes for the disease—one from each parent. The parents likely don't have the disease themselves.

CF mainly affects the lungs, pancreas, liver, intestines, sinuses, and sex organs.

Overview

Mucus is a substance made by tissues that line some organs and body cavities, such as the lungs and nose. Normally, mucus is a slippery, watery substance. It keeps the linings of certain organs moist and prevents them from drying out or getting infected.

If you have CF, your mucus becomes thick and sticky. It builds up in your lungs and blocks your airways. (Airways are tubes that carry air in and out of your lungs.)

The buildup of mucus makes it easy for bacteria to grow. This leads to repeated, serious lung infections. Over time, these infections can severely damage your lungs.

The thick, sticky mucus also can block tubes, or ducts, in your pancreas (an organ in your abdomen). As a result, the digestive enzymes that your pancreas makes can't reach your small intestine.

These enzymes help break down food. Without them, your intestines can't fully absorb fats and proteins. This can cause vitamin deficiency and malnutrition because nutrients pass through your body without being used. You also may have bulky stools, intestinal gas, a swollen belly from severe constipation, and pain or discomfort.

CF also causes your sweat to become very salty. Thus, when you sweat, you lose large amounts of salt. This can upset the balance of minerals in your blood and cause many health problems. Examples of these problems include dehydration (a lack of fluid in your body), increased heart rate, fatigue (tiredness), weakness, decreased blood pressure, heat stroke, and, rarely, death.

If you or your child has CF, you're also at higher risk for diabetes or two bone-thinning conditions called osteoporosis (OS-te-o-po-RO-sis) and osteopenia (OS-te-o-PEE-nee-uh).

CF also causes infertility in men, and the disease can make it harder for women to get pregnant. (The term "infertility" refers to the inability to have children.)

Outlook

The symptoms and severity of CF vary. If you or your child has the disease, you may have serious lung and digestive problems. If the disease is mild, symptoms may not show up until the teen or adult years.

The symptoms and severity of CF also vary over time. Sometimes you'll have few symptoms. Other times, your symptoms may become more severe. As the disease gets worse, you'll have more severe symptoms more often.

Lung function often starts to decline in early childhood in people who have CF. Over time, damage to the lungs can cause severe breathing problems. Respiratory failure is the most common cause of death in people who have CF.

As treatments for CF continue to improve, so does life expectancy for those who have the disease. Today, some people who have CF are living into their forties or fifties, or longer.

Early treatment for CF can improve your quality of life and increase your lifespan. Treatments may include nutritional and respiratory therapies, medicines, exercise, and other treatments.

Your doctor also may recommend pulmonary rehabilitation (PR). PR is a broad program that helps improve the well-being of people who have chronic (ongoing) breathing problems.

Other Names for Cystic Fibrosis

  • Cystic fibrosis of the pancreas
  • Fibrocystic disease of the pancreas
  • Mucoviscidosis (MU-ko-vis-ih-DO-sis)
  • Mucoviscidosis of the pancreas
  • Pancreas fibrocystic disease
  • Pancreatic cystic fibrosis

What Causes Cystic Fibrosis?

A defect in the CFTR gene causes cystic fibrosis (CF). This gene makes a protein that controls the movement of salt and water in and out of your body's cells. In people who have CF, the gene makes a protein that doesn't work well. This causes thick, sticky mucus and very salty sweat.

Research suggests that the CFTR protein also affects the body in other ways. This may help explain other symptoms and complications of CF.

More than a thousand known defects can affect the CFTR gene. The type of defect you or your child has may affect the severity of CF. Other genes also may play a role in the severity of the disease.

How Is Cystic Fibrosis Inherited?

Every person inherits two CFTR genes—one from each parent. Children who inherit a faulty CFTR gene from each parent will have CF.

Children who inherit one faulty CFTR gene and one normal CFTR gene are "CF carriers." CF carriers usually have no symptoms of CF and live normal lives. However, they can pass the faulty CFTR gene to their children.

The image below shows how two parents who are both CF carriers can pass the faulty CFTR gene to their children.

Who Is at Risk for Cystic Fibrosis?

Cystic fibrosis (CF) affects both males and females and people from all racial and ethnic groups. However, the disease is most common among Caucasians of Northern European descent.

CF also is common among Latinos and American Indians, especially the Pueblo and Zuni. The disease is less common among African Americans and Asian Americans.

More than 10 million Americans are carriers of a faulty CF gene. Many of them don't know that they're CF carriers.

What Are the Signs and Symptoms of Cystic Fibrosis?

The signs and symptoms of cystic fibrosis (CF) vary from person to person and over time. Sometimes you'll have few symptoms. Other times, your symptoms may become more severe.

One of the first signs of CF that parents may notice is that their baby's skin tastes salty when kissed, or the baby doesn't pass stool when first born.

Most of the other signs and symptoms of CF happen later. They're related to how CF affects the respiratory, digestive, or reproductive systems of the body.

Respiratory System Signs and Symptoms

People who have CF have thick, sticky mucus that builds up in their airways. This buildup of mucus makes it easier for bacteria to grow and cause infections. Infections can block the airways and cause frequent coughing that brings up thick sputum (spit) or mucus that's sometimes bloody.

People who have CF tend to have lung infections caused by unusual germs that don't respond to standard antibiotics. For example, lung infections caused by bacteria called mucoid Pseudomonas are much more common in people who have CF than in those who don't. An infection caused by these bacteria may be a sign of CF.

People who have CF have frequent bouts of sinusitis (si-nu-SI-tis), an infection of the sinuses. The sinuses are hollow air spaces around the eyes, nose, and forehead. Frequent bouts of bronchitis (bron-KI-tis) and pneumonia (nu-MO-ne-ah) also can occur. These infections can cause long-term lung damage.

As CF gets worse, you may have more serious problems, such as pneumothorax (noo-mo-THOR-aks) or bronchiectasis (brong-ke-EK-ta-sis).

Some people who have CF also develop nasal polyps (growths in the nose) that may require surgery.

Digestive System Signs and Symptoms

In CF, mucus can block tubes, or ducts, in your pancreas (an organ in your abdomen). These blockages prevent enzymes from reaching your intestines.

As a result, your intestines can't fully absorb fats and proteins. This can cause ongoing diarrhea or bulky, foul-smelling, greasy stools. Intestinal blockages also may occur, especially in newborns. Too much gas or severe constipation in the intestines may cause stomach pain and discomfort.

A hallmark of CF in children is poor weight gain and growth. These children are unable to get enough nutrients from their food because of the lack of enzymes to help absorb fats and proteins.

As CF gets worse, other problems may occur, such as:

  • Pancreatitis (PAN-kre-ah-TI-tis). This is a condition in which the pancreas become inflamed, which causes pain.
  • Rectal prolapse. Frequent coughing or problems passing stools may cause rectal tissue from inside you to move out of your rectum.
  • Liver disease due to inflamed or blocked bile ducts.
  • Diabetes.
  • Gallstones.

Reproductive System Signs and Symptoms

Men who have CF are infertile because they're born without a vas deferens. The vas deferens is a tube that delivers sperm from the testes to the penis.

Women who have CF may have a hard time getting pregnant because of mucus blocking the cervix or other CF complications.

Other Signs, Symptoms, and Complications

Other signs and symptoms of CF are related to an upset of the balance of minerals in your blood.

CF causes your sweat to become very salty. As a result, your body loses large amounts of salt when you sweat. This can cause dehydration (a lack of fluid in your body), increased heart rate, fatigue (tiredness), weakness, decreased blood pressure, heat stroke, and, rarely, death.

CF also can cause clubbing and low bone density. Clubbing is the widening and rounding of the tips of your fingers and toes. This sign develops late in CF because your lungs aren't moving enough oxygen into your bloodstream.

Low bone density also tends to occur late in CF. It can lead to bone-thinning disorders called osteoporosis and osteopenia.

How Is Cystic Fibrosis Diagnosed?

Doctors diagnose cystic fibrosis (CF) based on the results from various tests.

Newborn Screening

All States screen newborns for CF using a genetic test or a blood test. The genetic test shows whether a newborn has faulty CFTR genes. The blood test shows whether a newborn's pancreas is working properly.

Sweat Test

If a genetic test or blood test suggests CF, a doctor will confirm the diagnosis using a sweat test. This test is the most useful test for diagnosing CF. A sweat test measures the amount of salt in sweat.

For this test, the doctor triggers sweating on a small patch of skin on an arm or leg. He or she rubs the skin with a sweat-producing chemical and then uses an electrode to provide a mild electrical current. This may cause a tingling or warm feeling.

Sweat is collected on a pad or paper and then analyzed. The sweat test usually is done twice. High salt levels confirm a diagnosis of CF.

Other Tests

If you or your child has CF, your doctor may recommend other tests, such as:

  • Genetic tests to find out what type of CFTR defect is causing your CF.
  • A chest x ray. This test creates pictures of the structures in your chest, such as your heart, lungs, and blood vessels. A chest x ray can show whether your lungs are inflamed or scarred, or whether they trap air.
  • A sinus x ray. This test may show signs of sinusitis, a complication of CF.
  • Lung function tests. These tests measure how much air you can breathe in and out, how fast you can breathe air out, and how well your lungs deliver oxygen to your blood.
  • A sputum culture. For this test, your doctor will take a sample of your sputum (spit) to see whether bacteria are growing in it. If you have bacteria called mucoid Pseudomonas, you may have more advanced CF that needs aggressive treatment.

Prenatal Screening

If you're pregnant, prenatal genetic tests can show whether your fetus has CF. These tests include amniocentesis (AM-ne-o-sen-TE-sis) and chorionic villus (ko-re-ON-ik VIL-us) sampling (CVS).

In amniocentesis, your doctor inserts a hollow needle through your abdominal wall into your uterus. He or she removes a small amount of fluid from the sac around the baby. The fluid is tested to see whether both of the baby's CFTR genes are normal.

In CVS, your doctor threads a thin tube through the vagina and cervix to the placenta. The doctor removes a tissue sample from the placenta using gentle suction. The sample is tested to see whether the baby has CF.

Cystic Fibrosis Carrier Testing

People who have one normal CFTR gene and one faulty CFTR gene are CF carriers. CF carriers usually have no symptoms of CF and live normal lives. However, carriers can pass faulty CFTR genes on to their children.

If you have a family history of CF or a partner who has CF (or a family history of it) and you're planning a pregnancy, you may want to find out whether you're a CF carrier.

A genetics counselor can test a blood or saliva sample to find out whether you have a faulty CF gene. This type of testing can detect faulty CF genes in 9 out of 10 cases.

How Is Cystic Fibrosis Treated?

Cystic fibrosis (CF) has no cure. However, treatments have greatly improved in recent years. The goals of CF treatment include:

  • Preventing and controlling lung infections
  • Loosening and removing thick, sticky mucus from the lungs
  • Preventing or treating blockages in the intestines
  • Providing enough nutrition
  • Preventing dehydration (a lack of fluid in the body)

Depending on the severity of CF, you or your child may be treated in a hospital.

Specialists Involved

If you or your child has CF, you may be treated by a CF specialist. This is a doctor who is familiar with the complex nature of CF.

Often, a CF specialist works with a medical team of nurses, physical therapists, dietitians, and social workers. CF specialists often are located at major medical centers.

The United States also has more than 100 CF Care Centers. These centers have teams of doctors, nurses, dietitians, respiratory therapists, physical therapists, and social workers who have special training related to CF care. Most CF Care Centers have pediatric and adult programs or clinics.

Treatment for Lung Problems

The main treatments for lung problems in people who have CF are chest physical therapy (CPT), exercise, and medicines. Your doctor also may recommend a pulmonary rehabilitation (PR) program.

Chest Physical Therapy

CPT also is called chest clapping or percussion. It involves pounding your chest and back over and over with your hands or a device to loosen the mucus from your lungs so that you can cough it up.

You might sit down or lie on your stomach with your head down while you do CPT. Gravity and force help drain the mucus from your lungs.

Some people find CPT hard or uncomfortable to do. Several devices have been developed that may help with CPT, such as:

  • An electric chest clapper, known as a mechanical percussor.
  • An inflatable therapy vest that uses high-frequency airwaves to force the mucus that's deep in your lungs toward your upper airways so you can cough it up.
  • A small, handheld device that you exhale through. The device causes vibrations that dislodge the mucus.
  • A mask that creates vibrations that help break the mucus loose from your airway walls.

Breathing techniques also may help dislodge mucus so you can cough it up. These techniques include forcing out a couple of short breaths or deeper breaths and then doing relaxed breathing. This may help loosen the mucus in your lungs and open your airways.

Exercise

Aerobic exercise that makes you breathe harder can help loosen the mucus in your airways so you can cough it up. Exercise also helps improve your overall physical condition.

However, CF causes your sweat to become very salty. As a result, your body loses large amounts of salt when you sweat. Thus, your doctor may recommend a high-salt diet or salt supplements to maintain the balance of minerals in your blood.

If you exercise regularly, you may be able to cut back on your CPT. However, you should check with your doctor first.

Medicines

If you have CF, your doctor may prescribe antibiotics, anti-inflammatory medicines, bronchodilators, or medicines to help clear the mucus. These medicines help treat or prevent lung infections, reduce swelling and open up the airways, and thin mucus. If you have mutations in a gene called G551D, which occurs in about 5 percent of people who have CF, your doctor may prescribe the oral medicine ivacaftor (approved for people with CF who are 6 years of age and older).

Antibiotics are the main treatment to prevent or treat lung infections. Your doctor may prescribe oral, inhaled, or intravenous (IV) antibiotics.

Oral antibiotics often are used to treat mild lung infections. Inhaled antibiotics may be used to prevent or control infections caused by the bacteria mucoid Pseudomonas. For severe or hard-to-treat infections, you may be given antibiotics through an IV tube (a tube inserted into a vein). This type of treatment may require you to stay in a hospital.

Anti-inflammatory medicines can help reduce swelling in your airways due to ongoing infections. These medicines may be inhaled or oral.

Bronchodilators help open the airways by relaxing the muscles around them. These medicines are inhaled. They're often taken just before CPT to help clear mucus out of your airways. You also may take bronchodilators before inhaling other medicines into your lungs.

Your doctor may prescribe medicines to reduce the stickiness of your mucus and loosen it up. These medicines can help clear out mucus, improve lung function, and prevent worsening lung symptoms.

Treatments for Advanced Lung Disease

If you have advanced lung disease, you may need oxygen therapy. Oxygen usually is given through nasal prongs or a mask.

If other treatments haven't worked, a lung transplant may be an option if you have severe lung disease. A lung transplant is surgery to remove a person's diseased lung and replace it with a healthy lung from a deceased donor.

Pulmonary Rehabilitation

Your doctor may recommend PR as part of your treatment plan. PR is a broad program that helps improve the well-being of people who have chronic (ongoing) breathing problems.

PR doesn't replace medical therapy. Instead, it's used with medical therapy and may include:

  • Exercise training
  • Nutritional counseling
  • Education on your lung disease or condition and how to manage it
  • Energy-conserving techniques
  • Breathing strategies
  • Psychological counseling and/or group support

PR has many benefits. It can improve your ability to function and your quality of life. The program also may help relieve your breathing problems. Even if you have advanced lung disease, you can still benefit from PR.

Treatment for Digestive Problems

CF can cause many digestive problems, such as bulky stools, intestinal gas, a swollen belly, severe constipation, and pain or discomfort. Digestive problems also can lead to poor growth and development in children.

Nutritional therapy can improve your strength and ability to stay active. It also can improve growth and development in children. Nutritional therapy also may make you strong enough to resist some lung infections. A nutritionist can help you create a nutritional plan that meets your needs.

In addition to having a well-balanced diet that's rich in calories, fat, and protein, your nutritional therapy may include:

  • Oral pancreatic enzymes to help you digest fats and proteins and absorb more vitamins.
  • Supplements of vitamins A, D, E, and K to replace the fat-soluble vitamins that your intestines can't absorb.
  • High-calorie shakes to provide you with extra nutrients.
  • A high-salt diet or salt supplements that you take before exercising.
  • A feeding tube to give you more calories at night while you're sleeping. The tube may be threaded through your nose and throat and into your stomach. Or, the tube may be placed directly into your stomach through a surgically made hole. Before you go to bed each night, you'll attach a bag with a nutritional solution to the entrance of the tube. It will feed you while you sleep.

Other treatments for digestive problems may include enemas and mucus-thinning medicines to treat intestinal blockages. Sometimes surgery is needed to remove an intestinal blockage.

Your doctor also may prescribe medicines to reduce your stomach acid and help oral pancreatic enzymes work better.

Treatments for Cystic Fibrosis Complications

A common complication of CF is diabetes. The type of diabetes associated with CF often requires different treatment than other types of diabetes.

Another common CF complication is the bone-thinning disorder osteoporosis. Your doctor may prescribe medicines that prevent your bones from losing their density.

Living With Cystic Fibrosis

If you or your child has cystic fibrosis (CF), you should learn as much as you can about the disease. Work closely with your doctors to learn how to manage CF.

Ongoing Care

Having ongoing medical care by a team of doctors, nurses, and respiratory therapists who specialize in CF is important. These specialists often are located at major medical centers or CF Care Centers.

The United States has more than 100 CF Care Centers. Most of these centers have pediatric and adult programs or clinics. For more information about CF Care Centers, go to the Cystic Fibrosis Foundation's Care Center Network webpage. (Link is external.)

It's standard to have CF checkups every 3 months. Talk with your doctor about whether you should get an annual flu shot and other vaccines. Take all of your medicines as your doctor prescribes. In between checkups, be sure to contact your doctor if you have:

  • Blood in your mucus, increased amounts of mucus, or a change in the color or consistency of your mucus.
  • Decreased energy or appetite.
  • Severe constipation or diarrhea, severe abdominal pain, or vomit that's dark green.
  • A fever, which is a sign of infection. (However, you may still have a serious infection that needs treatment even if you don't have a fever.)

Transition of Care

Better treatments for CF allow people who have the disease to live longer now than in the past. Thus, the move from pediatric care to adult care is an important step in treatment.

If your child has CF, encourage him or her to learn about the disease and take an active role in treatment. This will help prepare your child for the transition to adult care.

CF Care Centers can help provide age-appropriate treatment throughout the transition period and into adulthood. They also will support the transition to adult care by balancing medical needs with other developmental factors, such as increased independence, relationships, and employment.

Talk with your child's health care team for more information about how to help your child move from pediatric care to adult care.

Lifestyle Changes

In between medical checkups, you can practice good self-care and follow a healthy lifestyle.

For example, follow a healthy diet. A healthy diet includes a variety of fruits, vegetables, and whole grains. Talk with your doctor about what types and amounts of foods you should include in your diet.

Other lifestyle changes include:

  • Not smoking and avoiding tobacco smoke
  • Washing your hands often to lower your risk of infection
  • Exercising regularly and drinking lots of fluids
  • Doing chest physical therapy (as your doctor recommends)

Other Concerns

Although CF requires daily care, most people who have the disease are able to attend school and work.

Adults who have CF can expect to have normal sex lives. Most men who have the disease are infertile (unable to have children). However, modern fertility treatments may help them.

Women who have CF may find it hard to get pregnant, but they usually can have children. If you have CF, you should talk with your doctor if you're planning a pregnancy.

Although CF can cause fertility problems, men and women who have the disease should still have protected sex to avoid sexually transmitted diseases.

Emotional Issues

Living with CF may cause fear, anxiety, depression, and stress. Talk about how you feel with your health care team. Talking to a professional counselor also can help. If you're very depressed, your doctor may recommend medicines or other treatments that can improve your quality of life.

Joining a patient support group may help you adjust to living with CF. You can see how other people who have the same symptoms have coped with them. Talk with your doctor about local support groups or check with an area medical center.

Support from family and friends also can help relieve stress and anxiety. Let your loved ones know how you feel and what they can do to help you.
