Asthma is a chronic respiratory disease that affects the airways of the lungs. It is characterized by intermittent inflammation of the respiratory airways, causing them to narrow and making breathing difficult. Typical symptoms include wheezing, chest tightness, persistent cough, and breathing difficulties, especially at night or early morning. The underlying mechanism of asthma is an abnormal inflammatory response of the bronchi to various stimuli, such as allergens, pollution, stress, or physical exertion.
Etiology
The causes of asthma are multifactorial, involving both genetic and environmental factors. Major risk factors include exposure to allergens (dust, animal hair, pollen), air pollution, smoking, and early respiratory infections. Additionally, recent studies have highlighted the potential impact of vitamin D deficiencies on worsening asthma symptoms. The imbalance of the intestinal and respiratory microbiome, as well as prenatal and postnatal stress, are also recognized as factors that can influence the onset and severity of asthma.
Symptoms
Asthma symptoms vary in intensity and can progress in episodes. The most common include:
c2 Wheezing: A high-pitched whistle, especially during exhalation.
5c2 Chest Tightness: A feeling of constriction in the chest.
5c2 Persistent Cough: Often worse at night or early morning.
5c2 Shortness of Breath: Difficulty breathing, especially after physical exertion.
These symptoms can fluctuate, with periods of remission between episodes. Asthma can be classified into different categories, ranging from intermittent to severe persistent asthma, depending on the frequency and severity of symptoms.
Treatments
The treatment of asthma mainly aims to control airway inflammation and prevent attacks. Therapeutic options include:
5c2 Rescue Medications: Bronchodilators, such as salbutamol, are used to quickly relieve symptoms during attacks.
5c2 Preventive Medications: Inhaled corticosteroids (such as beclometasone) are commonly used to reduce chronic airway inflammation.
5c2 Leukotriene Receptor Antagonists: Used when corticosteroids alone are not sufficient.
5c2 Theophyllines: Medications that help widen airways by relaxing bronchial muscles.
5c2 Trace Elements: Treatments using trace elements like selenium and gold can be used in addition to modulate inflammatory response.
Prevention
Asthma prevention involves managing risk factors and adopting certain practices to reduce episodes:
5c2 Allergen Control: Minimizing exposure to domestic allergens (dust, animal hair, etc.) and using anti-mite covers.
5c2 Healthy Lifestyle: Avoiding smoking, maintaining regular physical activity, and managing stress.
5c2 Supplementation: Adequate vitamin D intake could play a role in preventing asthma attacks, although further studies are needed to confirm this link.
Asthma patients should regularly follow their treatment and adjust their medications based on medical advice.
