Cystic fibrosis (CF) is a hereditary condition affecting the secretory glands that produce mucus and sweat. The gene responsible for CF triggers the body to produce a thick, sticky substance that clogs the airways and leads to respiratory and digestive problems. The symptoms vary widely among individuals, depending on the severity of the condition. Understanding the signs and symptoms is crucial for early diagnosis and management. Today, we’ll explore 10 key symptoms to help you spot CF early.

A persistent cough producing thick mucus is often the first sign of CF.1 This cough isn’t merely an irritation; it’s a significant indication that the lungs are struggling with thick mucus obstructing the airways.
The body attempts to clear the blockage by coughing, but the thickness of the mucus makes this an ongoing challenge. Over time, the relentless coughing can lead to fatigue, interfere with daily activities, and even cause physical harm like fractured ribs.
Symptom 2: Frequent Lung Infections
CF patients are at an increased risk of contracting lung infections such as bronchitis and pneumonia. The thick mucus provides a breeding ground for bacteria, making it easier for infections to take hold. These infections are not only difficult to treat but can become chronic, causing permanent damage to the lungs and escalating the overall severity of the condition.
Symptom 3: Wheezing and Shortness of Breath
As the mucus clogs the airways, it becomes challenging to breathe properly. This leads to wheezing and shortness of breath, which can become progressively worse without proper treatment. The lack of oxygenation impacts daily life, making even simple tasks like climbing stairs or walking short distances a struggle. Exercise becomes almost impossible, further affecting overall health and well-being.
Symptom 4: Salty-Tasting Skin
One unusual symptom of CF is that the skin tastes salty. This occurs due to a defect in the body’s chloride channels, causing a higher concentration of salt in the sweat. Parents often notice this when kissing their children. This unique symptom has led to the development of a sweat test, which is an essential diagnostic tool for CF.2
Symptom 5: Poor Growth and Weight Gain
Digestive issues are a common part of CF, leading to poor growth and weight gain, especially in children. The thick mucus blocks the pancreas from releasing digestive enzymes, hampering the absorption of essential nutrients. Without these nutrients, the body struggles to grow and maintain weight, leading to a failure to thrive, and often requiring specialized dietary planning and supplementation.
Symptom 6: Intestinal Blockage
The thick, sticky mucus can lead to severe intestinal blockages, particularly in newborns. This can be life-threatening and usually requires immediate medical intervention. It’s often a signal to healthcare providers to test for CF, particularly if the blockage occurs soon after birth. This can lead to early diagnosis and treatment, improving the child’s long-term outlook.
Symptom 7: Severe Constipation
Along with intestinal blockages, severe constipation is a frequent problem due to the thick mucus obstructing the bowels. This isn’t merely a minor discomfort; it’s a major health concern that can lead to significant pain, requiring medical treatment. Proper hydration, diet, and sometimes medical intervention are needed to manage this symptom.
Symptom 8: Male Infertility
Infertility is an issue for most men with CF.3 The condition often blocks or even eliminates the vas deferens, the tube carrying sperm. Although this does not affect sexual function, it means that most men with CF are unable to father children without medical assistance. This symptom underscores the wide-ranging impact of CF, affecting not just physical health but family planning and emotional well-being.
Symptom 9: Clubbing of Fingers and Toes
Clubbing of the fingers and toes is a physical deformity often seen in chronic lung diseases like CF. The fingertips and toes become rounded and enlarged. While the exact mechanism behind clubbing is not fully understood, it’s thought to be related to long-term oxygen deprivation in the extremities. It’s often considered a sign of more advanced CF.
Symptom 10: Chronic Sinusitis
Inflammation and chronic infections in the sinuses are prevalent in CF.4 The thick mucus traps bacteria in the sinuses just as it does in the lungs, leading to continuous discomfort and a higher risk of infections. Treatment often involves antibiotics and other medications, but sinusitis can be a relentless and disruptive symptom for those with CF.
