requiring comprehensive screening to identify underlying causes.
While coughing is a natural defense mechanism against foreign matter, excessive coughing that disrupts daily life is classified as chronic, highly sensitive to environmental or temperature shifts and requiring a professional clinical evaluation to identify the diverse underlying causes.
-
01
Acute Cough
Duration under 3 weeks, mostly caused by common colds.
Typically resolves spontaneously within 2 to 3 weeks. -
02
Subacute Cough
Duration of 3 to 8 weeks, driven by post-infectious infection.
Suspect early-stage asthma or gastroesophageal reflux (GERD). -
03
Chronic Cough
Duration over 8 weeks, severely disrupting daily activities.
Associated with asthma, eosinophilic bronchitis, or tumors.
-
01 Post-Nasal Drip
Caused by rhinitis or sinusitis, where excess mucus flows down the back of the throat.
Triggers a chronic cough, throat discomfort, and localized throat pain in severe cases.
Managed via saline nasal douching 2-4 times daily and avoiding overeating or caffeine. -
02 Bronchial Asthma
• A respiratory disease presenting with a dry cough, wheezing, and episodic dyspnea.
• Strongly suspected if coughing worsens at night, during cold weather, or post-cold over a month.
• Often exacerbated by environmental triggers such as tobacco smoke, exhaust, or fragrances. -
03 Bronchiectasis
• Chronic destruction of bronchial walls, frequently occurring after severe tuberculosis infections.
• Produces a persistent cough accompanied by over 30ml of thick sputum production per day.
• Diagnosed via CT/X-ray imaging to initiate management aimed at preventing disease progression.
-
04 GERD
• Acid reflux causing indigestion, heartburn, chronic coughing, and a lump sensation in the throat.
• Requires targeted long-term medical management typically lasting between 1 to 6 months.
• Strict lifestyle modification needed: Avoid caffeine and fast at least 2 hours before bedtime.
-
• Indicates suspected chronic bronchitis; accompanied by persistent cough or throat pain.
• Clinical evaluation required if respiratory symptoms consistently last for over 2 weeks. -
• Signals potential pneumonia or lung cancer; hemoptysis demands immediate medical tracking.
• Early intervention is vital before the underlying respiratory disease rapidly deteriorates. -
• Suggests bacterial infections like Pseudomonas aeruginosa or Haemophilus influenzae.
• Diagnosis needed if coughing persists over 2 weeks or sputum lasts for 2 months. -
• Linked to heavy air pollution, yellow dust, tobacco smoke, or fungal infections.
• Requires targeted screening to determine the precise environmental or infectious source.
