Congestion

What Is Congestion?

Congestion is the buildup of excess fluid or mucus in the body’s tissues or airways, causing a feeling of blockage or fullness. The term most commonly refers to nasal congestion, but it can also describe congestion in the chest or lungs associated with certain respiratory or heart conditions.

The underlying cause determines the most appropriate treatment for congestion.

Why Congestion Matters

Congestion can make breathing more difficult, interfere with sleep, reduce comfort, and, in some cases, signal a more serious medical condition that requires treatment.

Common Causes of Congestion

  • Common cold
  • Influenza (flu)
  • COVID-19
  • Allergies
  • Sinus infections
  • Chronic obstructive pulmonary disease (COPD)
  • Heart failure causing fluid congestion

Common Symptoms

  • Stuffy or blocked nose
  • Runny nose
  • Chest tightness
  • Cough
  • Difficulty breathing
  • Facial pressure
  • Difficulty sleeping

How Is Congestion Treated?

Treatment depends on the cause and may include rest, hydration, saline nasal sprays, medications, humidified air, allergy management, or treatment of an underlying heart or lung condition.

How Home Care Can Help

Home care professionals monitor breathing, encourage hydration, assist with prescribed treatments, reinforce medication schedules, observe for worsening symptoms, and communicate concerns to the healthcare provider.

Home Care Tip

Drink plenty of fluids unless your healthcare provider advises otherwise. Staying hydrated can help thin mucus and make congestion easier to manage.
