A person who is having difficulty breathing feels short of breath, has trouble inhaling or exhaling, or feels as though they cannot get enough oxygen.
Very often, people experience trouble breathing after exercising or when they feel anxious. In some cases, breathing difficulties can signal a medical condition, so it is essential to work out the cause.
In this article, we look at the possible reasons why people might experience difficulty breathing. We also cover the diagnosis, treatment, and prevention of this symptom.
Colds or flu
People with a common cold or the flu may have difficulty breathing. These illnesses cause the following symptoms, which can make breathing more difficult:
- stuffy nose
- a sore throat
- inflamed airways
- excess mucus in the airways
When a cold, flu, or chest infection is the cause of breathing difficulties, the symptoms should clear up when the illness resolves. Learn how to ease the symptoms of a cold here.
Anxiety can cause physical symptoms, including shortness of breath or breathing difficulties. A person’s breath is likely to return to normal once their anxiety eases.
Other symptoms of anxiety include:
- feeling nervous or on edge
- raised heart rate
- a sense of doom
- difficulty concentrating
- digestive problems
People may sometimes experience extreme anxiety or panic attacks that resemble a heart attack. Other symptoms of a panic attack can include:
- a raised or pounding heartbeat
- a feeling of choking
- chest pain
- numbness or tingling
- chills or heat sensations

Asthma is a chronic disease that causes the airways leading to the lungs to become inflamed.
As with other chronic conditions, a person’s asthma will flare from time to time, usually as a result of exposure to a trigger. Triggers can vary between people but could include exercise, smoke, or particular allergens.
Common asthma symptoms include:
- chronic coughing
- tightness in the chest
- difficulty sleeping due to coughing or wheezing
A person who has obesity or does not exercise regularly may experience periods during which they have difficulty breathing.
Short periods of exertion can cause a person to feel out of breath.
If weight or a lack of exercise is the cause of breathing difficulty, starting an exercise regimen and following a healthful diet can significantly contribute to reducing or eliminating the problem.
COPD is a term that describes several lung disorders, including chronic asthma, emphysema, and chronic bronchitis. COPD symptoms may worsen at night due to changes in the way that a person breathes while sleeping.
COPD can cause a range of symptoms, such as:
- shortness of breath
- chest pain
- fatigue, as a result of reduced oxygen in the blood
According to the American Lung Association, emphysema is one of the diseases under the COPD umbrella.
Emphysema thins and destroys the alveoli, or air sacs, in the lungs. The inhalation of cigarette smoke is a leading cause of this condition.
The primary symptoms of emphysema include:
- increased phlegm
- shortness of breath during activities
Anaphylaxis is a severe allergic reaction. It is a life-threatening condition that requires immediate medical attention. Anaphylaxis progresses quickly, but it has some early warning signs and symptoms.
These may include:
- tightness in the throat
- trouble breathing
- a hoarse voice
- abdominal pain
- cardiac arrest
- rapid heartbeat
- low blood pressure
- a sense of doom
As pregnancy progresses, the fetus becomes bigger and can start to push on surrounding organs and muscles. These include the diaphragm, which is a muscle directly below the lungs that helps a person take deep breaths.
If the uterus pushes against the diaphragm, this can make it more difficult for the person to take deep breaths.
In addition to the expanding uterus, people may experience difficulty breathing during pregnancy due to progesterone, a hormone that the body produces in larger quantities during pregnancy. Progesterone can make someone feel as though they cannot take a deep breath.
If other symptoms arise, pregnancy is unlikely to be the cause of breathing issues, and it is best to see a doctor to determine the cause.
According to the American Heart Association, difficulty breathing is one of the common warning signs of a heart attack. Therefore, anyone experiencing this symptom should pay attention to any other symptoms that occur.
If a person experiences the following symptoms, they should get medical attention immediately:
- chest discomfort
- trouble breathing
- discomfort in the back, jaw, neck, stomach, or one or both arms
- cold sweats
There are many possible causes of breathing difficulties. Whenever a person has trouble breathing for unknown reasons, they should see their doctor.
At an appointment, the doctor will ask about the other symptoms that a person is experiencing. In some cases, this may be enough for the doctor to determine the cause.
In other cases, a doctor may want to run tests to help diagnose the problem. These tests may include:
- allergy tests
- chest X-rays
- lung tests
- CT scans
- spirometry and methacholine challenge tests
- arterial blood gas analysis
Who is at risk?
Risk factors vary greatly depending on the cause of the breathing problem.
For example, children are more at risk of choking than adults, while smokers have a higher likelihood of developing emphysema. People with asthma are more at risk of having breathing trouble following exercise or exposure to allergens.
Keeping active and eating a healthful, balanced diet can help prevent many issues with breathing that can develop over a person’s lifetime.
The cause of the breathing difficulty will determine the treatment. Some common treatments could include:
- removal of an object in the throat, in cases of choking
- inhalers for asthma and other upper respiratory conditions
- an epinephrine autoinjector (EpiPen) for anaphylaxis
- eating smaller meals for acid reflux and COPD
- antacids for acid reflux
In some cases, people can improve their breathing by using specific breathing exercises to increase their lung capacity. Learn about these exercises here.
When to see a doctor
A person should seek immediate medical attention if they experience difficulty breathing that causes them to feel faint or occurs alongside other symptoms of a heart attack.
Otherwise, a person with unexplained shortness of breath or other breathing problems should speak to their doctor to determine what is causing the issue.
There are many potential ways to prevent the development of breathing difficulties. Some steps to consider include:
- taking smaller bites of food and avoiding placing loose objects in the mouth
- avoiding smoking and breathing in secondhand smoke
- taking allergy medications and avoiding known allergens
- eating healthful meals and exercising regularly
- eating smaller meals
- taking prescribed medications for chronic conditions and avoiding triggers
There are several different causes of breathing difficulty. Anyone with concerns about this symptom should see their doctor. Some causes are chronic, such as COPD, while others are temporary, for example, the common cold.
If symptoms are severe, the person will need immediate medical attention.
A person can typically avoid having difficulty breathing by avoiding triggers and living a healthful lifestyle that includes eating well and exercising regularly.
