Wheezing in Adults

Common Causes

• Asthma — Chronic airway inflammation and spasms may narrow breathing tubes, especially with triggers like allergens or exercise.
• Chronic Obstructive Pulmonary Disease (COPD) — Long-term lung damage, often from smoking, can cause ongoing airway blockage and mucus buildup.
• Gastroesophageal Reflux Disease (GERD) — Acid reflux might irritate airways, leading to spasms and wheezing in some cases.
• Heart Failure — Fluid buildup in the lungs could narrow airways, mimicking breathing problems.
• Allergies or Anaphylaxis — Severe reactions to foods, insects, or pollen may cause sudden airway swelling.
