COPD is a lung disease that causes breathing problems. All information about this chronic disease.
Every year, she is responsible for 18,000 deaths on average in France, according to Public Health France. COPD is a chronic, progressive respiratory disease that affects the airways. Most commonly associated with other conditions, it can cause Significant respiratory obstruction.
Definition, symptoms, stages, causes and treatment, we evaluate these lung diseases.
Definition: What is COPD?
chronic obstructive pulmonary disease, or chronic pulmonary obstructioncorresponds to a chronic respiratory disease affect the airways. It is characterized by slow and gradual obstruction of the airways and lungs.
COPD is most commonly associated with Chronic bronchitis or to Emphysema. In the vast majority of cases, the Smoking is the cause of diseasealthough air pollution and exposure to chemicals are also implicated.
According to the World Health Organization (WHO), more than three million people die around the world every year. So it will be The third leading cause of death. Individuals over 45 years of age are most affected.
The first symptom of COPD is Wet cough with phlegm (Spit out a whitish secretion) in the morning. This is called a “smoker’s cough.” There is also Shortness of breath on exertion (shortness of breath), increasing in severity as the disease progresses. Then this respiratory discomfort occurs at the slightest daily gesture, which changes the quality of life.
COPD also has stages of exacerbation Several times a year, no periods of marked exacerbation of symptoms.
Chronic obstructive pulmonary disease: different stages of development
There are several stages of COPD development and severity, ranked from 0 to 4. They are based on an indicator called FEV1, for Maximum volume of exhaled (air) in one second.
- stage 0 : This is the ‘at-risk’ stage of COPD. Some chronic symptoms such as a wet cough may be observed. Respiratory function test is normal.
- Stage 1 (light) : FEV1 greater than or equal to 80%, with or without chronic symptoms.
- Stage 2 (moderate) : FEV1 ranges from 50 to 80%. We often see a file exertional shortness of breath (Deficiency of air) of unknown origin.
- stage 3 (severe) : FEV1 ranges from 30 to 50%. This results in a decrease in physical abilities and a frequent need to catch one’s breath.
- Stage 4 (very severe) : FEV1 then is less than 30% or less than 50% with a respiratory failure. Shortness of breath appears at the slightest effort.
COPD causes and factors
The smoking, active as passive, is the leading cause of obstructive pulmonary disease, being responsible in about 80% of cases, according to Inserm. The longer and more intense the consumption, the higher the risk of disease. In fact, tobacco causes Mucus production in the bronchiWhich causes obstruction and the emergence of bronchial infections.
Besides smoking and cannabis use, another important risk factor for COPD isChronic exposure to contaminated productsWhether on the street (outdoor air pollution), at home (indoor air pollution) or at work (coal or silica dust, agricultural products, solvents, etc.).
Treatment: How do we treat COPD?
It is clear that the first step in treating COPD is Remove pathogensEither stop using tobacco or be exposed to pollutants. This initially slows the progression of the disease.
However, there is no No treatment can completely cure COPD. Medicines called BronchodilatorsIt can help reduce shortness of breath by expanding the airways. For people with chronic respiratory failure,Oxygen therapy Suggestion. It is an oxygen therapy that is taken daily.
sessions Respiratory physical therapy It is also indicated to improve respiratory capacity. It consists of a set of exercises that gradually allow to rehabilitate the respiratory system.
