Shortness of Breath in Adults

Common Causes

• Asthma — Airways may narrow due to inflammation or triggers like allergens, making it harder to breathe during attacks.
• Heart failure — The heart might not pump blood well, leading to fluid buildup in the lungs that reduces air flow.
• Anxiety or panic attacks — Stress could speed up breathing, creating a sense of air hunger even when oxygen levels are normal.
• Anemia — Low red blood cells might carry less oxygen, so the body works harder to breathe.
• Obesity — Extra weight could press on the lungs and diaphragm, limiting how much air you take in.
