Poitrine et poumons

Asthme

Le système respiratoire comprend les poumons, la trachée et le diaphragme, parmi d'autres structures et organes. Vous aurez appris tout cela lors des cours de biologie à l'école, mais depuis, beaucoup considèrent la respiration comme acquise. Cependant, une toux ou une respiration sifflante pourrait être le signe de problèmes plus graves à venir.

Asthme

Asthma is a chronic disease of the airways that causes breathing difficulties. When exposed to triggers, the airway linings swell, excess mucus is produced, and the surrounding muscles tighten, making breathing difficult.

les difficultés respiratoires

Difficulty breathing is the subjective feeling of being unable to get enough air or having to work too hard to breathe. It can feel like chest tightness, gasping, or an inability to take a full breath. Severe breathing problems require emergency medical attention.

Infections pulmonaires

Chest and lung infections (often called lower respiratory tract infections) occur when viruses, bacteria, or fungi invade your airways or lung tissue. The most common types are bronchitis and pneumonia.

Douleur thoracique

Chest pain refers to any discomfort, ache, or pressure felt anywhere between the neck and the upper abdomen. While frequently associated with heart issues, it can also originate from respiratory, gastrointestinal, muscular, or psychological conditions.

BPCO

COPD is a progressive lung condition that makes it hard to breathe. It is an umbrella term for long-term respiratory diseases, primarily emphysema (damage to the air sacs) and chronic bronchitis (inflamed, mucus-filled airways).

Toux

A cough is a natural reflex to clear your airways of irritants, mucus, or foreign particles. It is usually caused by a viral infection, allergies, or environmental irritants. A cough lasting over three weeks should be evaluated by a healthcare professional.

Affections pulmonaires

Lung conditions are broadly classified by how they affect breathing and the respiratory system. They can damage the airways, the tiny air sacs (alveoli) responsible for gas exchange, or the surrounding lung tissue and blood vessels.
