What is Bronchiectasis? What Are the Symptoms? How Is It Diagnosed and Treated?

What is Bronchiectasis, What Are the Symptoms, and How Is It Diagnosed and Treated: Bronchiectasis is a chronic lung disease in which the airways (bronchi) that carry air to the lungs become permanently widened and their structure deteriorates over time. Symptoms such as frequent coughing, excessive phlegm, and recurrent infections can make daily life difficult. The good news is that when the disease is detected early and followed up regularly, most patients can lead a comfortable and active life.

What Is Bronchiectasis and How Does It Develop?

Our lungs contain airways that allow us to breathe, which branch out and become thinner like tree branches; these are called bronchi. In bronchiectasis, these airways become permanently widened and their walls weaken due to recurrent infection and inflammation. Because the flexible structure of the bronchial wall is damaged, this resulting dilation is irreversible.

The disease follows a chronic course and progresses over time if left untreated. It is most commonly seen in the lower left region of the lung. While some individuals are born with it, in most patients, it develops later as a result of past infections, immune system problems, or foreign bodies entering the respiratory tract. However, in approximately 40% of patients, a definitive cause cannot be found.

What happens in the lungs:

The inner surface of healthy bronchi is covered with a thin layer of mucus (phlegm). This layer serves to trap and expel harmful substances and germs from the air we breathe. When the bronchi widen, this mucus accumulates more than normal and becomes difficult to expel.

The accumulated mucus creates a suitable environment for germs. As infection develops, the bronchi are further damaged, which leads to more mucus accumulation and new infections. This creates a vicious cycle, and the damage in the lungs deepens over time. The goal of treatment is to break this very cycle.

Types of bronchiectasis:

Three main types are defined according to the shape of the bronchial dilation:

• Cylindrical (tubular) type: The most common and generally the mildest type. The bronchi widen like a smooth tube.

• Varicose type: The bronchi widen and narrow in places; its appearance resembles varicose veins. It is a moderate type.

• Cystic (saccular) type: The most severe type. The bronchi widen to the point of becoming sacs (cysts) filled with secretions.

What Causes Bronchiectasis:

Bronchiectasis usually occurs as a result of damage left by another problem affecting the lung. The main causes are as follows:

Past lung infections:

One of the most common causes is severe lung infections, especially those experienced in childhood. Diseases such as pneumonia, tuberculosis, whooping cough, and measles can cause permanent damage to the bronchial walls. This risk increases in infections that are not treated in a timely and adequate manner. Fungal infections and some viral infections can also damage the airways.

Immune system problems:

People with weak immune systems are more susceptible to infections; recurrent lung infections also pave the way for bronchiectasis. Connective tissue diseases such as rheumatoid arthritis and scleroderma, inflammatory bowel diseases such as Crohn's disease and ulcerative colitis, as well as conditions like HIV and diabetes can increase the risk.

Hereditary and congenital causes:

In some patients, the cause is hereditary. In developed countries, the most common hereditary cause is cystic fibrosis, which leads to the production of thick and sticky secretions, causing airway obstruction and infection. In addition, some genetic diseases such as primary ciliary dyskinesia and alpha-1 antitrypsin deficiency, as well as conditions where the bronchial structure develops differently from birth, can also lead to bronchiectasis.

Smoking and environmental factors:

Smoking irritates the bronchi, lowers resistance to infections, and worsens the course of the disease. Long-term exposure to harmful chemical gases and smoke also damages the airways. In addition to these, chronic lung diseases such as COPD, reflux disease where stomach contents flow back, airway obstructions, and some benign bronchial tumors can also contribute to bronchiectasis.

What Are the Symptoms of Bronchiectasis

Symptoms vary from person to person. While some patients have only mild complaints, others may have various symptoms that make daily life difficult. Complaints often develop slowly over months or even years.

Persistent cough and excessive phlegm:

The most common symptom is a persistent cough that occurs almost every day. The cough increases especially in the mornings and after physical activity. The cough is usually accompanied by abundant phlegm; the phlegm is often yellow-green in color and can sometimes be foul-smelling. Thickening and foul-smelling phlegm often indicate an increase in infection.

Shortness of breath and chest pain:

Due to the mucus accumulated in the airways and the damage that occurs over time, shortness of breath may occur; this can be felt even during mild exertion. There may also be pain in the chest, a feeling of fullness, or wheezing when coughing or taking a deep breath.

Blood in the phlegm (hemoptysis):

In a significant portion of patients, blood may come with phlegm; this is called hemoptysis. Most of the time, it is in the form of light streaks of blood in the phlegm. However, rarely, a larger amount of blood may come; this situation requires urgent evaluation. When you see a significant amount of bloody phlegm, consult a healthcare institution without delay.

Fatigue and fever:

Due to chronic infection and the inability to get enough oxygen, there may be constant fatigue and weakness. During periods when the infection flares up, fever, night sweats, and a deterioration in general condition may be observed.

Changes in fingertips (clubbing):

When sufficient oxygen cannot be obtained for a long time, the fingertips may widen and become rounded, and the nails may become bulbous like a spoon. This finding, called "clubbing," usually appears in advanced stages.

How Is Bronchiectasis Diagnosed?

Diagnosis begins with listening to your complaints. Your doctor will evaluate how long the symptoms have been going on, your past lung infections, your chronic diseases, and your family history. Then, some tests are performed to clarify the diagnosis.

Physical examination

Your lungs are listened to with a stethoscope. Depending on the mucus and dilation in the airways, abnormal breathing sounds called "rales" may be heard. The color and amount of your phlegm, whether there is bloody phlegm, and how much shortness of breath affects your daily life are also evaluated.

Imaging methods (Tomography and X-ray)

The most valuable method in the diagnosis of bronchiectasis is high-resolution computed tomography (CT) of the lung. Tomography shows the dilation in the bronchi, wall thickening, and structural changes in detail and confirms the diagnosis.

A chest X-ray is usually the first-step test; although it provides some clues, it may be insufficient to show bronchiectasis on its own. For this reason, in case of suspicion, further examination is performed with tomography. In some cases, bronchoscopy may also be required to directly view the inside of the airways.

Pulmonary function tests

These tests, performed by blowing into a device, measure your lung capacity and the degree of narrowing in the airways. They are also repeated regularly to monitor the course of the disease over time.

Phlegm and blood tests

A phlegm culture determines which germ is causing the infection; this allows for the selection of the most appropriate antibiotic for you. Blood tests evaluate the infection and the immune system. When necessary, cystic fibrosis tests and genetic examinations can also be performed to investigate the underlying cause.

Bronchiectasis Treatment and Quality of Life

The main goal of treatment is to control symptoms, reduce infections, and slow the progression of the disease. Although bronchiectasis does not disappear completely, the quality of life improves significantly with the right treatment. Treatment is planned specifically for each patient.

Drug therapy

Antibiotics are used to control infections; the choice of medication is made according to the result of the phlegm culture whenever possible. Mucolytic drugs that thin the phlegm and make it easier to expel, and bronchodilator drugs that open the airways and reduce shortness of breath can also be added to the treatment. In patients who have frequent attacks, low-dose long-term antibiotic treatment that is effective against both germs and inflammation may be considered. Flu and pneumonia vaccines are also important in protecting against infections.

Respiratory physiotherapy and pulmonary rehabilitation

Regularly clearing phlegm from the airways is one of the most important parts of treatment. Special positions called postural drainage, breathing exercises, and auxiliary devices such as flutter help to expel sticky phlegm more easily. Pulmonary rehabilitation programs increase lung capacity and endurance with exercise training. These techniques can be applied regularly at home after being learned under the guidance of a physiotherapist.

Surgical treatment

If the disease is concentrated in a limited area of the lung and cannot be sufficiently controlled with medication, the surgical option comes to the fore. In this case, the diseased lung region (lobe) is removed. The success rate of surgery is quite high in suitable patients.

Today, most of these surgeries can be performed using the closed (camera-assisted, VATS) method. Since small incisions of a few centimeters are used in this method, patients usually feel less pain and are discharged within a few days. As with any surgery, there is a possibility of complications such as bleeding or infection; however, this risk is low in suitable patients. In patients whose quality of life has deteriorated significantly, who have recurrent bloody phlegm, or who are frequently hospitalized, surgery can significantly improve the quality of life.

Lifestyle recommendations

• If you smoke, quit immediately and stay away from cigarette smoke.

• Pay attention to consuming enough fluids to make it easier to expel phlegm.

• Eat a balanced diet and do regular, light exercise with your doctor's approval.

• Stay away from dusty, smoky, and polluted environments.

• Get your flu and pneumonia vaccines regularly.

• Do not skip your check-ups and apply without delay when your complaints increase.

What happens if it is not treated?

In untreated bronchiectasis, infections become more frequent, hospitalizations increase, and the disease can progress to respiratory failure by further impairing lung functions over time. Rarely, emergencies such as severe bleeding can also occur. For this reason, early diagnosis and regular follow-up are of great importance.

Frequently Asked Questions

Bronchiectasis does not disappear completely because it is a permanent change that has occurred in the airways. However, this does not mean that the disease will restrict your life. With the right medications, regular respiratory physiotherapy, and healthy lifestyle habits, symptoms can be kept under control. Patients who are diagnosed early and followed up regularly mostly lead an active and comfortable life.

Bronchiectasis is a condition that requires lifelong follow-up. It is important not to skip your check-ups, to stay away from cigarettes and cigarette smoke, to avoid dusty and polluted environments, to take enough fluids, to eat a balanced diet, and to do the regular exercise recommended by your doctor. Do not forget to get your flu and pneumonia vaccines, follow the recommendations for respiratory physiotherapy, and apply immediately when your complaints increase. Ask for a phlegm culture to be done if possible before starting antibiotics.

Although it is not possible to prevent some causes (e.g., hereditary diseases), there are ways to reduce the risk: Treating lung infections completely, not interrupting medications, getting flu and pneumonia vaccines, following the vaccination schedule of children, and staying away from cigarettes and harmful smoke are at the beginning of these. Especially in children, if a foreign body is swallowed, a healthcare institution should be consulted immediately as the airway may be blocked.

Bronchiectasis is a chronic disease and although it does not heal completely, it can be controlled. With early diagnosis, regular follow-up, and correct treatment, your symptoms can be kept under control; your quality of life will increase significantly. Quitting smoking, getting your vaccines, applying your respiratory physiotherapy regularly, and not skipping your check-ups are the most important steps to successfully managing the disease. Remember: bronchiectasis is a condition that can be lived with comfortably when managed correctly.
