Shortness of breath at night: causes, diagnosis, and treatment of the symptom
About the Symptom
Nighttime shortness of breath, or nocturnal dyspnea, is a condition in which a person experiences difficulty breathing while asleep. This can manifest as feelings of a lack of air, rapid breathing, or a sense of panic. Nighttime shortness of breath can be either a seasonal occurrence or a symptom of more serious conditions, such as heart failure, obstructive sleep apnea, or lung diseases. If you notice that your breathing becomes heavy, especially in a horizontal position, this may indicate the need to consult a specialist for diagnosis and treatment.
During sleep, the body relaxes, and often people do not realize how their breathing changes. Nighttime shortness of breath can lead to frequent awakenings, disrupting sleep quality and causing daytime fatigue. It is important to understand that nighttime shortness of breath can be a signal of potential health issues, so it is recommended to carefully monitor how often it occurs and what factors may provoke it. For example, factors such as excess weight, smoking, or the presence of chronic diseases can contribute to worsening the condition. Consult a doctor to rule out serious pathologies and receive advice on alleviating symptoms.
Diseases
Shortness of breath at night, or orthopnea, can be a sign of various diseases that require the attention of medical specialists. One of the most common causes of nighttime shortness of breath is cardiovascular diseases, such as heart failure. In this condition, the heart cannot effectively pump blood, leading to fluid accumulation in the lungs and, consequently, difficulty breathing. Additionally, lung diseases such as chronic obstructive pulmonary disease (COPD) and asthma can also cause episodes of shortness of breath, especially when lying down, when the lungs experience additional pressure.
One should not forget about the impact of neurological diseases, such as dysfunction of the central nervous system, which can disrupt the control of breathing. Nighttime shortness of breath can also be associated with sleep apnea, a condition where there is a temporary cessation of breathing during sleep. Each of the aforementioned diseases requires comprehensive diagnosis and appropriate treatment to alleviate symptoms and improve the patient’s quality of life.
- Heart failure
- Chronic obstructive pulmonary disease (COPD)
- Asthma
- Sleep apnea
- Pneumonia
- Pulmonary embolism
- Pleurisy
- Neurological disorders
Diagnosis
Proper diagnosis is a key stage in identifying the causes of shortness of breath, especially if it occurs at night. A variety of conditions can lead to this symptom, and a competent doctor should conduct a thorough analysis of the patient’s condition. First of all, the specialist collects a medical history by inquiring about the nature of the shortness of breath, associated symptoms, and possible triggers. Recording information about the duration and intensity of episodes can provide significant clues to the source of the problem.
Various diagnostic procedures are used to confirm the diagnosis. They may include imaging methods, functional tests, and laboratory analyses. The main goal of diagnosis is to determine whether shortness of breath is a result of cardiovascular diseases, lung pathologies, or other disorders, which often requires the involvement of specialists from different fields of medicine.
- General clinical blood tests
- Chest X-ray
- Computed tomography (CT) of the chest organs
- Spirometry
- Electrocardiogram (ECG)
- Ultrasound examination (US) of the heart
- Nocturnal polysomnographic studies
- Tests for blood oxygenation levels
Which doctor to consult
If you experience shortness of breath at night, it is important not to delay a visit to the doctor. This symptom may indicate various diseases that require timely diagnosis and treatment. You may need to see several specialists, depending on your accompanying symptoms and medical history.
The first doctors to consult are a therapist and a pulmonologist. The therapist will help conduct an initial examination and determine possible causes of shortness of breath, and will refer you to more narrow specialists if necessary.

Types of Nighttime Dyspnea
Nighttime dyspnea can manifest in various ways, and each may indicate different causes. One type is paroxysmal nocturnal dyspnea, characterized by a sudden episode of shortness of breath during sleep. This type of dyspnea is often accompanied by coughing and can lead to waking a person due to respiratory distress. Causes can range from cardiovascular diseases to bronchial asthma.
Another common type is orthopnea, which manifests as difficulty breathing while in a horizontal position. People with this type of dyspnea may feel relief when sitting up. Orthopnea is often seen in patients with heart failure and chronic lung diseases, and requires immediate medical attention.
- Paroxysmal nocturnal dyspnea (sudden shortness of breath during sleep)
- Orthopnea (difficulty breathing while lying down)
- Coughing dyspnea (episodes of shortness of breath accompanied by coughing)
- Nocturnal wheezing (wheezing sounds while breathing)
- Exacerbation of chronic respiratory diseases (e.g., asthma or COPD)
Causes of shortness of breath at night
Shortness of breath at night is a symptom that can be caused by various factors, and its causes can be both physiological and pathological. It is important to understand that the occurrence of shortness of breath at night often signals the presence of serious diseases. First and foremost, respiratory diseases such as asthma or chronic obstructive pulmonary disease (COPD) can be the cause of shortness of breath. In such cases, patients may experience difficulty breathing while lying on their back due to the accumulation of secretions or inflammatory processes in the lungs.
Additionally, nighttime shortness of breath may be related to cardiovascular diseases such as heart failure. In this case, fluid may accumulate in the lungs, causing difficulty in breathing. There are also other causes, such as allergic reactions, excess weight which may lead to compression of the airways during sleep, or neurological disorders. Thus, identifying the causes of nighttime shortness of breath requires careful diagnosis and consultation with specialists.
- Respiratory diseases (asthma, COPD)
- Cardiovascular diseases (heart failure)
- Allergic reactions
- Excess weight and obesity
- Neurological disorders
Common Related Pathologies
Nightly shortness of breath can be a symptom of various diseases that require careful analysis and diagnosis. One of the most frequent causes is heart failure, where the heart cannot effectively pump blood, leading to fluid accumulation in the lungs and difficulty breathing when lying down. This process is often accompanied by coughing fits and wheezing, which can impair sleep quality and the patient’s overall physical activity.
Additionally, nighttime shortness of breath can also be associated with respiratory diseases such as asthma or chronic obstructive pulmonary disease (COPD). In these cases, shortness of breath occurs due to narrowing of the airways, making normal breathing difficult during sleep. This is especially noticeable at night when patients may wake up from choking or a lack of air.
- Heart failure
- Chronic obstructive pulmonary disease (COPD)
- Asthma
- Pneumonia
- Allergic reactions
- Sleep apnea
