What causes difficulty breathing when lying down? 20 possible conditions
It is not uncommon to become short of breath after physical activities or during moments of extreme stress. However, if you have difficulty breathing after lying down, this may be a sign or side effect of a serious medical condition. Certain diseases, anxiety disorders, and lifestyle factors may cause breathing difficulty, and this condition is not always a medical emergency. However, any difficulty breathing when lying down should be reported to your doctor right away.
Common causes for difficulty breathing when lying down are:
- panic disorder
- respiratory infections
- sleep apnea
- chronic obstructive pulmonary disease (COPD)
Sleep apnea is a condition that causes a person to have shallow or brief pauses in breathing while sleeping. This condition is usually caused by an obstruction in the airways.
Lying down too soon after eating may cause difficulty breathing. This may be due food regurgitating up your esophagus or due to the pressure of the food in your stomach pressing down on your diaphragm. Your diaphragm separates your stomach from your lungs. This uncomfortable feeling is generally relieved by sitting up for a few hours until the food digests.
People who are obese or extremely overweight may experience difficulty breathing when lying down. This is because excess weight puts pressure on the lungs and diaphragm. Wearing tight clothing may cause the same feeling.
In some cases, breathing difficulty can be a sign of a medical emergency. Severe causes for difficulty breathing when lying down include heart failure.
Initial symptoms may include a feeling of being breathless upon lying flat on your back. You may feel like you have difficulty taking deep breaths or breathing out. If this symptom was caused by a medical condition such as sleep apnea or COPD (a lung disease that blocks airflow), other symptoms may be present.
Symptoms of sleep apnea include:
- difficulty staying asleep
- feeling fatigued during the day
- snoring while sleeping
- waking up with headaches
- waking up with a sore throat
Symptoms of COPD include:
- chronic coughing
- difficulty breathing with activity
- frequent chest infections like bronchitis
If you experience any of the following symptoms along with difficulty breathing, seek medical attention immediately:
- pain in the chest
- pains in the arms and neck or shoulders (often described as shooting pain)
- rapid breathing
- rapid heart rate
- weak pulse
- dizziness upon standing or sitting
While breathing difficulty may not always be a sign of a serious medical condition, you should talk to your doctor about any breathing issues right away. To diagnose the underlying cause of your breathing difficulty, your doctor will perform a physical examination, review your symptoms, and ask you about your medical history. You should also notify your doctor if you begin having difficulty breathing after taking a prescription or over-the-counter medication. Certain drugs used to treat pain, muscle stiffness, or anxiety can cause breathing issues. (ALSA)
A physical exam will pay close attention to your heart and lungs. Additional tests may be needed, such as:
- chest X-rays to view the heart and lungs
- echocardiogram to better view and diagnose potential problems with heart function
- electrocardiogram (ECG) to test the electrical activity in the heart
Treatment will depend on the underlying cause of your breathing difficulty.
If you have a respiratory infection that causes breathing difficulty when lying down, your doctor may prescribe antibiotics or antiviral medications to help clear up an infection. However, in most cases minor chest infections may clear up without the use of any medications.
Difficulty breathing caused by obesity may be relieved temporarily by sleeping on your side instead of your back. Lying on your side decreases the pressure being put on your lungs by the excess weight. Talk to your doctor about successful weight loss or dieting plans to shed excess pounds and prevent future health concerns associated with obesity.
While there is no cure for COPD, breathing difficulties may be relieved after using fast-acting inhalers (such as Albuterol) or other medications used to clear up any infections of the lungs, such as bronchitis.
Difficulty breathing when lying down caused by sleep apnea may be helped with the use of assistive devices such as mouth guards or a continuous positive airway pressure (CPAP) device.
If an anxiety disorder is causing your breathing issues, various treatments can help ease symptoms. Group or one-on-one therapy may be help you cope with anxiety. Therapy is usually combined with antidepressant or antianxiety medications. These medications are available by prescription only.
