Common Respiratory Disorders

Upper respiratory disorders affect airways above the vocal cords, including the nose, sinuses, and throat, causing nasal congestion and sneezing. Lower respiratory disorders impact airways below the vocal cords, primarily the lungs, and include conditions like asthma, bronchitis, and pneumonia that cause wheezing and breathing difficulties.

The common cold and allergic rhinitis result from infections or allergen exposure. These conditions trigger nasal congestion, sneezing, coughing, and runny nose symptoms. Inflammatory upper respiratory conditions such as pharyngitis, tonsillitis, and laryngitis stem from bacterial or viral infections affecting throat tissues.

Asthma is a chronic inflammatory disorder causing airway hyperresponsiveness and reversible airflow obstruction, manifesting as wheezing, breathlessness, and chest tightness. Chronic bronchitis causes inflammation of the bronchial tubes, leading to persistent coughing and mucus production rather than reversible airflow obstruction.

Pneumonia inflames the alveoli and fills them with pus, commonly caused by bacteria, viruses, or fungi. This inflammation leads to fever and difficulty breathing. In bacterial pneumonia specifically, pus accumulates in the alveoli, severely impairing gas exchange and oxygen delivery.

Other significant lower respiratory disorders include pulmonary hypertension, cystic fibrosis, pulmonary fibrosis, and chronic obstructive pulmonary disease (COPD). These conditions can severely affect lung function and overall quality of life, requiring comprehensive management and treatment strategies to preserve respiratory health.

Treatment varies depending on disorder nature and severity. Medications manage symptoms and prevent flare-ups, while lifestyle changes such as quitting smoking and improving indoor air quality support recovery. Respiratory therapy or surgery may be necessary for severe or complex cases to preserve lung health.

Upper respiratory infections present with nasal congestion, sneezing, coughing, and runny nose. Inflammatory conditions like pharyngitis and tonsillitis cause throat soreness and difficulty swallowing. These symptoms may cause discomfort and impede daily activities, requiring appropriate diagnosis and management for recovery.
