Emphysema: Causes, Signs and Treatment

Do not smoke

In emphysema, the lungs’ air sacs are damaged over time, making breathing difficult. When these air pockets are punctured and leak, it decreases the available surface area for gas exchange. As a result of this illness, you may have difficulty breathing, particularly while exercising. Emphysema may lead to malnutrition and muscular weakness in the legs in advanced stages.

Emphysema is mostly caused by smoking, although other lung irritants may also play a role. Treatments such as stopping smoking and medicines may help slow the growth of the illness and control symptoms, but there is currently no cure for emphysema.

Causes of Emphysema: Exposure to Irritants and Genetic Factors

Long-term exposure to airborne irritants is the primary cause of emphysema. The lung air sacs’ inner walls are damaged, and one huge air gap is created rather than numerous tiny ones, leading to a decrease in oxygen supply to the blood. Tobacco use is the leading cause of emphysema in about 75% of patients. Chemical fumes or dust from the environment or the job, air pollution, and secondhand smoking are further potential irritants that might lead to emphysema. Alpha-1-antitrypsin deficiency and other rare genetic variables have also been linked to its development.

Smoking as the Leading Cause of Emphysema

Tobacco use is a major contributor to COPD and its most severe form, emphysema. Emphysema is more likely to develop in those who have been exposed to airborne irritants for a long time, such as those who smoke cigarettes, cigars, or pipes. It may be exacerbated by breathing in noxious substances such as air pollution, chemical fumes, or dust from the environment or the job. Emphysema may also be caused by a rare hereditary protein deficit known as alpha-1-antitrypsin deficiency.

A person may be at higher risk for getting emphysema if, for instance, they have smoked for many years and work in a plant with high amounts of chemical vapors. A person’s chance of developing alpha-1-antitrypsin insufficiency is increased if there is a history of the disorder in his or her family.

Symptoms of Emphysema

Symptoms of emphysema may be subtle at first but grow increasingly severe over time.

  • The most noticeable sign of emphysema is shortness of breath. This may start off mild and progress to the point where normal daily activities become challenging. Breathlessness may occur even while doing nothing strenuous.
  • Breathing might sound whistling or squeaky for some people with emphysema. This might be a sign of air being stuck in the lungs or of an obstruction in the airways.
  • As the condition advances, emphysema patients may also experience an increase in the frequency of respiratory infections. This is because airborne bacteria and viruses have an easier time penetrating and infecting lung tissue that has been injured.
  • Emphysema may lead to muscular weakness and weight loss in later stages. This is because the body’s other organs have to work harder to compensate for the fact that the lungs aren’t getting enough oxygen.

Diagnosing Emphysema: Medical History and Diagnostic Tests

Smoking is the leading culprit, although exposure to secondhand smoke, air pollution, and chemical fumes may also play a role. Emphysema may be diagnosed by a patient’s medical history and other testing. A spirometer is a piece of diagnostic equipment used to measure an individual’s lung capacity. Emphysema may be detected and diagnosed with the use of tests like a chest X-ray and a computed tomography (CT) scan. The efficiency with which a person’s lungs take in oxygen and exhale carbon dioxide from the blood may be measured using blood tests and noninvasive procedures.

Lung sounds for emphysema

Emphysema is characterized by wheezing, which may be detected using a stethoscope. The sounds coming from the lungs might be anything from wheezing to cracking. During a physical examination, a doctor or nurse will pay close attention to any signs of irregular breathing. Diagnostic studies, including chest x-rays, CT scans, and blood tests, may supplement a physical examination to confirm a diagnosis of emphysema.

COPD: Emphysema and Chronic Bronchitis

Smoking, air pollution, and chemical fumes may all lead to emphysema, a type of chronic obstructive pulmonary disease (COPD). Large air pockets form in the lungs as a result of the disease’s effect on the alveoli, or air sacs. This may lead to weariness, shortness of breath, and coughing. Imaging and respiratory tests may identify emphysema, and medicine and smoking cessation are effective treatments. COPD-related disorders, such as chronic bronchitis, may occur in tandem with the underlying condition. 

Is emphysema a restrictive or obstructive lung disease?

Emphysema is a subtype of COPD, which is a prevalent and curable lung condition marked by ongoing respiratory symptoms and airflow restriction.

The air sacs beyond the terminal bronchiole are largely affected by emphysema, making it a pathological diagnosis. Disruption of the lung parenchyma and lack of elasticity define this condition, together with the abnormal, permanent expansion of air pockets inside the lungs.

Doctors classify lung conditions as obstructive or restrictive lung diseases. Obstructive lung disease includes conditions that make it hard to exhale all the air in the lungs. In contrast, people with restrictive lung disease have difficulty fully expanding their lungs with air. Obstructive and restrictive lung diseases share the same main symptom: shortness of breath with exertion. Obstructive lung disease makes it harder to breathe, especially during increased activity or exertion, while people with restrictive lung disease cannot fully fill their lungs with air.

Pulmonary function tests are used to diagnose either restrictive or obstructive lung disease. The lung capacity and respiratory rate are evaluated using these tests. Imaging tests, such as chest X-rays and computed tomography (CT) scans, are also often used by clinicians. Bronchoscopy is a procedure used to examine the airways and collect tissue samples from the lungs in order to determine the lung condition causing obstructive or restrictive lung disease.


Treatment Options for Emphysema

Options for treating emphysema target symptom management, complication avoidance, and disease retardation.

The single most effective measure that emphysema sufferers may take to improve their condition is to quit smoking. It is also important to limit exposure to other lung irritants such as secondhand smoking, smog, and chemical odors.

Inhalers (bronchodilators) may be used to relax and open the air passageways in the lungs, while steroids can alleviate the symptoms of asthma and bronchitis. Respiratory infections may sometimes be treated with antibiotics.

Supplemental oxygen treatment may be necessary for patients with advanced emphysema, either at home or in a medical facility. Lung volume reduction surgery involves removing tiny wedges of diseased lung tissue from certain individuals.

Pulmonary rehabilitation includes education, dietary counseling, breathing methods, smoking cessation support, and an exercise program and is an important aspect of treating emphysema. Patients with physical impairments may benefit from engaging in regular physical exercise.
