Pulmonology Guide: Understanding Chest and Lung Health

medica-seed-editor · November 4, 2026, 1:21pm

Pulmonology focuses on the diagnosis and treatment of disorders affecting the lungs and respiratory organs, which can impact oxygen levels and cause chest pain.

Types of Chest Diseases and Their Effects

Respiratory issues vary based on the affected part of the chest:

Airway disorders: These lead to the narrowing or blockage of gas-transporting passages. Examples include asthma, chronic obstructive pulmonary disease (which includes emphysema and chronic bronchitis), cystic fibrosis, and acute bronchitis.
Lung tissue problems: These cause inflammation or scarring in the lung structure, hindering expansion and gas exchange, such as pulmonary fibrosis and sarcoidosis.
Pulmonary circulation disorders: These affect blood vessels due to clotting or inflammation, most notably pulmonary hypertension.
Chest wall problems: These include neuromuscular disorders such as myasthenia gravis and amyotrophic lateral sclerosis, as well as the impact of morbid obesity, which hinders chest expansion.

Other Lung Diseases and Common Conditions

There are various other lung diseases and chest injuries that may have different causes:

Infections: Such as influenza, pneumonia caused by fungi, bacteria, or viruses, and tuberculosis.
Tumors: Such as lung cancer, which may begin in the air sacs.
Acute conditions: Such as acute respiratory distress syndrome, which may require the use of ventilators.
Environmental irritants: Such as black lung disease, which affects coal miners.

The Difference Between Asthma and Allergies

Both are exaggerated immune responses to specific triggers, but they differ in symptoms and location:

Allergies: These often affect the upper respiratory tract, appearing as sneezing, runny nose, and watery eyes.
Asthma: A chronic inflammation that causes the bronchial muscles to contract and increases mucus secretion, leading to wheezing, persistent coughing, and difficulty breathing that may cause nighttime awakenings.

Angina and Thoracic Vertebrae

Issues in the chest area are not limited to the lungs:

Angina: This is related to heart health and occurs due to reduced blood flow; it is diagnosed via electrocardiogram (ECG), stress tests, or coronary angiography.
Thoracic vertebrae: This section consists of 12 vertebrae that protect the spinal cord and vital organs. They may be subject to mechanical pain due to poor posture, age-related degenerative diseases, or deformities such as scoliosis and kyphosis.

Frequently Asked Questions

What is the difference between asthma and allergies?

Allergies typically affect the upper respiratory tract, causing sneezing and a runny nose, while asthma is a chronic inflammation of the airways that causes shortness of breath and wheezing.

How is thoracic vertebrae pain treated?

Treatment depends on the cause; it may include physical therapy and exercises for muscle spasms, pain relievers and anti-inflammatories, or facet joint injections. In cases of fractures or deformities, braces or surgical intervention may be necessary.

What are the symptoms of chest infections in adults?

Symptoms vary between an intermittent cough, colored mucus, wheezing during breathing, and fatigue. In chronic cases, a cough with phlegm persists for 3 months per year for at least two consecutive years.

When to Visit a Pulmonology Specialist?

Medical care should be sought immediately if the following signs appear:

Fever above 38°C accompanied by chest pain and loss of appetite.
Coughing up blood or a sudden increase in the thickness and color of phlegm.
Respiratory symptoms persisting for more than three weeks.
Unexplained weight loss.
Severe difficulty breathing that prevents sleep or daily activities.
