What Causes Wheezing When Lying Down? Symptoms, Diagnosis & Treatment

What Causes Wheezing When Lying Down?

Wheezing can be an alarming sensation. You may experience wheezing when lying down as a whistle or squeaky sound when breathing out. This symptom often signals an underlying condition that makes it more difficult to breathe.

Asthma

Asthma is one of the most common causes of wheezing. This chronic condition inflames and narrows the bronchial tubes in your lungs. Irritants like pet dander, smoke, pollution, or a respiratory infection can trigger asthma symptoms like:

• Coughing
• Shortness of breath
• Chest tightness
• Wheezing when breathing out

Lying down can worsen asthma symptoms because gravity causes more pressure on the lungs. This extra weight makes it harder to push air out, resulting in that whistling wheeze.

COPD

Chronic obstructive pulmonary disease (COPD) is a progressive disease that makes it difficult to breathe. COPD includes chronic bronchitis and emphysema.

With COPD, less air flows in and out because of inflammation and damage in the airways and air sacs. Common symptoms include:

• Constant coughing with mucus
• Wheezing or whistling sound when breathing out
• Chest tightness
• Shortness of breath, especially with activity

Lying down can intensify wheezing since gravity limits how well your lungs can expand and contract.

Pulmonary Fibrosis

Pulmonary fibrosis is a lung disease that causes scarring in the lungs. With pulmonary fibrosis, the lung tissue becomes damaged and scarred over time, impeding oxygen flow.

Scarring from pulmonary fibrosis makes the lungs less flexible and elastic. Symptoms include:

• Shortness of breath
• Chronic dry, hacking cough
• Fatigue and weakness
• Wheezing

Gravity pressing down on stiff lung tissue can lead to wheezing when lying down.

Heart Failure

When the heart cant pump enough blood to meet the bodys needs, its called heart failure. Fluid can back up into the lungs in heart failure, causing breathing difficulties.

Common symptoms of heart failure include:

• Fatigue
• Shortness of breath with activity or when lying down
• Wheezing or rattling sound when breathing
• Chronic cough
• Swelling in legs, feet, or abdomen

The wheezing occurs due to fluid accumulation in or around the lungs. Gravity causes more fluid shift into the lungs when lying flat.

When to See a Doctor About Wheezing

Occasional mild wheezing may not require medical care. But seek emergency care if you experience:

• Severe wheezing or shortness of breath
• Difficulty speaking
• Swelling of the lips or face
• Rapid heartbeat

These signs may indicate anaphylaxis, a life-threatening allergic reaction that requires an epinephrine injection.

See your doctor if you experience wheezing along with:

• Fever
• Cough with green or yellow mucus
• Unexplained weight loss
• Swelling in the legs or abdomen

Review all your medications with your doctor since some may cause wheezing as a side effect.

Diagnosing the Cause of Wheezing When Lying Down

To determine the cause of your wheezing, your doctor will:

• Take a medical history
• Perform a physical exam
• Listen to your breathing with a stethoscope

They may order additional tests such as:

• Pulmonary function tests - These measure how well your lungs take in and release air.
• Chest x-ray - This creates images of your lungs and heart to check for abnormalities.
• CT scan - This detailed imaging test can reveal lung damage and other issues.
• Arterial blood gas - This blood test gauges oxygen and carbon dioxide levels.
• Echocardiogram - This ultrasound checks heart function.

Treatment Options for Wheezing When Lying Down

Treatment focuses on managing the underlying cause of wheezing. Options may include:

Medications

Types of medications used for wheezing and breathing issues include:

• Bronchodilators - These medications relax tightened airway muscles to make breathing easier. Inhaled short-acting bronchodilators provide quick relief for wheezing episodes. Long-acting forms help control chronic symptoms.
• Inhaled steroids - These counter airway swelling and mucus production.
• Oxygen therapy - Additional oxygen can ease breathing difficulties.
• Diuretics - Also called "water pills," these remove excess fluid that could accumulate in the lungs.

Pulmonary Rehabilitation

This therapeutic program combines patient education, breathing techniques, exercise training, and nutritional counseling. Pulmonary rehabilitation aims to improve overall lung function.

Surgery

Surgery may help remove damaged lung tissue or widen constricted airways. Procedures for chronic wheezing and breathing problems may include:

• Lung volume reduction surgery
• Lung transplant
• Airway stent placement

Severe, recurrent wheezing can damage lung tissue over time and interfere with quality of life. Work closely with your healthcare provider to protect lung health.

Preventing Wheezing Episodes

You can reduce flare-ups of wheezing by:

• Taking all prescribed medications for lung disease
• Quitting smoking and avoiding secondhand smoke
• Controlling indoor asthma and allergy triggers
• Exercising to strengthen breathing muscles
• Maintaining a healthy weight
• Getting recommended vaccines like the flu shot and pneumonia vaccine

Let your doctor know if you experience increased wheezing episodes, even with preventive care. Adjustments to your treatment plan may help.
