What is Respiratory Infections & Asthma?
Respiratory infections and asthma are common health conditions that affect the respiratory system. Respiratory infections, caused by viruses or bacteria, can lead to symptoms like coughing, wheezing, chest tightness, shortness of breath, and fatigue. Common infections include the common cold, flu, pneumonia, and bronchitis. Asthma, a chronic condition, causes inflammation and narrowing of the airways, leading to difficulty breathing, wheezing, and coughing, especially during physical activity or exposure to triggers like allergens, cold air, or smoke.
Causes Of Respiratory Infections & Asthma:
- Viral Infections: Common viruses like the flu, common cold, or respiratory syncytial virus (RSV) can lead to respiratory infections.
- Bacterial Infections: Bacteria such as Streptococcus pneumoniae or Mycoplasma pneumoniae can cause conditions like pneumonia or bronchitis.
- Environmental Factors: Exposure to allergens, pollutants, or irritants such as cigarette smoke can weaken the respiratory system, making it more susceptible to infections.
- Weakened Immune System: Individuals with compromised immune systems, such as those with HIV, diabetes, or other chronic conditions, are at higher risk.
- Genetics: Family history of asthma or other allergic conditions can increase the likelihood of developing asthma.
- Allergens: Pollen, dust mites, pet dander, and mold can trigger asthma symptoms in sensitive individuals.
Symptoms of Respiratory Infections & Asthma:
- Shortness of Breath – Difficulty breathing or a feeling of tightness in the chest.
- Wheezing – A high-pitched whistling sound when breathing, especially during exhalation.
- Chest Pain or Tightness – Discomfort or tightness in the chest area, particularly with deeper breaths.
- Increased Sensitivity to Triggers – Symptoms worsen with exposure to allergens, smoke, or changes in weather.
- Increased Mucus Production – Excess mucus in the airways, causing coughing or difficulty breathing.
- Coughing – Chronic coughing, especially at night or in the early morning, often dry or accompanied by mucus.
