Asthma is a condition characterized by the narrowing and swelling of airways, often accompanied by excess mucus production. Symptoms include difficulty breathing, coughing fits, wheezing during exhalation, and shortness of breath. Triggers can vary, with allergens like pet dander or dust being common culprits. Some individuals may experience asthma symptoms in response to specific diets or physical activity. Genetic factors can contribute, with a familial history of allergic symptoms such as asthma, allergic rhinitis, and urticaria.

< Allergic Rhinitis:

Allergic rhinitis results from the immune system's reaction to foreign substances like pollen, bee venom, or pet dander. The immune system produces antibodies in response to these allergens, leading to inflammation in the skin, sinuses, airways, or digestive system. Allergy severity varies, ranging from mild inflammation to severe emergencies like anaphylaxis. While extreme allergies may not be curable, medications can help alleviate symptoms.

Pulmonary Fibrosis involves scarring and stiffness of lung tissues, making breathing challenging and potentially leading to respiratory failure, heart failure, or other complications. Researchers attribute Pulmonary Fibrosis to factors such as genetics, immune system activity, smoking, and exposure to lung irritants like chemicals and infections. Initially thought to be primarily caused by inflammation, it is now believed that scarring results from a specific healing process over time.

COPD is characterized by inflammation and thickening of lung airways, accompanied by the destruction of the tissue responsible for oxygen exchange. This condition leads to reduced airflow in and out of the lungs, resulting in decreased oxygen intake and difficulty expelling carbon dioxide. Referred to as chronic bronchitis or emphysema, COPD symptoms often include a combination of both conditions. While prevention and treatment options are available, it is crucial to address COPD promptly to maintain lung function and overall well-being.
