Cystic fibrosis (CF) is a disease that is passed down through families. It is caused by a defective gene that makes the body produce abnormally thick and sticky fluid, called mucus. This mucus builds up in the breathing passages of the lungs and in the pancreas.
Excessive mucus can be a symptom of bronchitis, chronic obstructive pulmonary disease (COPD), bronchiectasis, or cystic fibrosis.
Conditions that can contribute to excess mucus include allergies, asthma, and bronchitis. Smoking and conditions like COPD and cystic fibrosis can also cause this symptom. Your doctor may order a sputum test to find the cause of your excess mucus.
The stomach, nose, sinuses, and throat can all produce mucus, so getting a good diagnosis requires a medical examination. Possible causes of excess mucus can be food allergies, an acid reflux from the stomach, or an infection.
Allergic reactions and respiratory infections like colds, the flu, and sinus infections can cause your body to produce even more mucus. Even something as simple as eating spicy food can trigger increased mucus production, and when you think about it, it makes sense.
It is a common symptom of conditions such as the common cold, sinusitis, and allergies. The excess mucus can be caused by inflammation or swelling of the nasal passages, which can be due to a variety of factors such as viral or bacterial infections, allergies, or irritants in the air.
Catarrh is a build-up of mucus in an airway or cavity of the body. It usually affects the back of the nose, the throat or the sinuses (air-filled cavities in the bones of the face). It's often temporary, but some people experience it for months or years. This is known as chronic catarrh.
CF mucus is often described as more solid and having a “flake” form. In addition, it has a higher concentration of proteins called mucins. Mucins make up the main component of mucus and are responsible for the gel-consistency of mucus.
A number of disorders may mimic CF: Hirschsprung's disease. bronchiolitis. protein calorie malnutrition.
Genetic testing may be done to see if you carry the mutated gene that triggers cystic fibrosis. A sweat test may also be conducted. CF causes higher than normal levels of salt in your sweat. Doctors will examine the levels of salt in your sweat to confirm a diagnosis.
Sometimes, however, signs of the disease may not show up until adolescence or even later. Infants or young children should be tested for CF if they have persistent diarrhea, bulky foul-smelling and greasy stools, frequent wheezing or pneumonia, a chronic cough with thick mucus, salty-tasting skin, or poor growth.
Just three decades ago, the average person with cystic fibrosis would live only to the age of 30, but now 50 years is typical, and some patients with CF live into their 80s. This means they live long enough for other health concerns to surface.
While most cystic fibrosis patients are diagnosed by the time they are two years old, and others are diagnosed in adulthood.
While cystic fibrosis is usually diagnosed in childhood, adults with no symptoms (or mild symptoms) during their youth can still be found to have the disease.
Symptoms of cystic fibrosis. The signs and symptoms of cystic fibrosis generally begin to occur around 6-8 months after birth, though this can differ significantly from person to person. Symptoms tend to differ depending on age and can affect various areas of the body.
CF causes thick mucus to build up and clog certain parts of the body such as the lung. The buildup is caused by an abnormal gene called CFTR (cystic fibrosis transmembrane regulator). CFTR controls the flow of water and salt in and out of the body's cells. Changes cause mucus to become thickened and sticky.
Cystic Fibrosis Diagnosis
Most people are diagnosed with CF at birth with newborn screening, or before 2 years of age. A doctor who sees the symptoms of CF will order a sweat test or a genetic test to confirm the diagnosis. A sweat test is the most common test used to diagnose CF. It is a painless test.
Bronchiectasis is a long-term condition where the airways of the lungs become abnormally widened, leading to a build-up of excess mucus that can make the lungs more vulnerable to infection. The most common symptoms of bronchiectasis include: a persistent cough that usually brings up phlegm (sputum) breathlessness.
