Common causes of feeling short of breath are: lung problems, such as asthma and chronic obstructive pulmonary disease (COPD) heart problems, such as a cardiovascular disease and heart failure. infections in the airways, such as croup, bronchitis, pneumonia, COVID-19, the flu and even a cold.
Key Facts. If your breathing has become labored and difficult for no obvious reason, it may be the sign of a more serious medical problem. If chest pain or pressure, fainting or nausea accompanies shortness of breath, you should treat it as a medical emergency.
If shortness of breath happens when you're clearly not exerting yourself, when you're doing something you normally could do without feeling winded, or comes on suddenly, those are warning signs that a heart issue could potentially be to blame.
While there are many causes of shortness of breath, the most common causes are lung disease, heart disease, or deconditioning (lack of exercise, especially in people who are overweight or obese).
obesity or being unfit. poorly controlled asthma. chronic obstructive pulmonary disease (COPD) – permanent damage to the lungs usually caused by years of smoking. anaemia – a low level of oxygen in the blood caused by a lack of red blood cells or haemoglobin (the part of red blood cells that carries oxygen)
Our experts recommend scheduling an appointment with your doctor if your shortness of breath is accompanied by swelling in your feet and ankles, trouble breathing when you lie flat, high fever, chills and cough, or wheezing. You should also see a doctor if you notice shortness of breath becoming more severe.
Shortness of breath is often a symptom of heart and lung problems. But it can also be a sign of other conditions like asthma, allergies or anxiety. Intense exercise or having a cold can also make you feel breathless.
Commonly these include blood tests, imaging tests such as a chest X-ray or CT scan, lung function tests or an echocardiogram.
If you have breathlessness, you experience shortness of breath and difficulty breathing. The medical term is dyspnoea. It may come on suddenly (acute) or gradually over a period of time (chronic). The reason for breathlessness is that the body needs more oxygen than it is getting.
Warning signs and symptoms of heart failure include shortness of breath, chronic coughing or wheezing, swelling, fatigue, loss of appetite, and others.
Most cases of shortness of breath are due to heart or lung conditions. Your heart and lungs are involved in transporting oxygen to your tissues and removing carbon dioxide, and problems with either of these processes affect your breathing.
Stage 2 of Congestive Heart Failure
Stage two of congestive heart failure will produce symptoms such as fatigue, shortness of breath, or heart palpitations after you participate in physical activity.
Medications that can precipitate respiratory impairment include ACE inhibitors, NSAIDs, anticonvulsants, beta blockers, calcium channel blockers, cholinergics, antihypertensives, antibiotics, antifungals, antimicrobials, antiretrovirals, digoxin, interferon, and chemotherapy agents.
"Chest pain, rapid heartbeat and breathlessness may result when an insufficient amount of blood reaches the heart muscle," says Tung. (See "Symptoms" below.) One of the key distinctions between the two is that a heart attack often develops during physical exertion, whereas a panic attack can occur at rest.
People can experience shortness of breath while walking for a number of reasons. Sometimes, this occurs as a result of conditions such as anxiety, asthma, or obesity. Less commonly, shortness of breath signals a more serious underlying medical condition.
Shortness of breath — known medically as dyspnea — is often described as an intense tightening in the chest, air hunger, difficulty breathing, breathlessness or a feeling of suffocation. Very strenuous exercise, extreme temperatures, obesity and higher altitude all can cause shortness of breath in a healthy person.
Seek emergency medical care if your shortness of breath is accompanied by chest pain, fainting, nausea, a bluish tinge to lips or nails, or a change in mental alertness — as these may be signs of a heart attack or pulmonary embolism.
CAD happens when coronary arteries struggle to supply the heart with enough blood, oxygen and nutrients. Cholesterol deposits, or plaques, are almost always to blame. These buildups narrow your arteries, decreasing blood flow to your heart. This can cause chest pain, shortness of breath or even a heart attack.
People with breathlessness tell us that it affects their lives in several ways. It can make it difficult to manage your everyday activities. It can also make you feel frustrated or frightened. But the good news is that there are many things that you can do to cope, so that you can live well with breathlessness.
When your body experiences anxiety, it goes into fight-or-flight mode to protect itself from an immediate threat. It releases adrenaline, a hormone that pumps blood to your muscles and causes your body temperature to rise. It also sends most of your oxygen to your muscles, which is why you may feel short of breath.
Use Pursed Lip Breathing when walking. Inhale through your nose and exhale through pursed lips. Exhale slowly and comfortably, not forcibly, breathing out twice as long as you breath in. This will keep your breathing slow and restore oxygen to your body more rapidly.
Apart from taking a detailed clinical history and physical examination the primary methods of evaluating shortness of breath are through an electrocardiogram (ECG) and a chest X-ray. These are quick and inexpensive tests that provide your cardiologist with a baseline diagnosis to confirm or exclude certain diagnoses.
“Getting diagnosed with heart failure usually starts when you notice symptoms such as shortness of breath, fatigue, rapid or irregular heartbeat or swelling in the legs, ankles, feet or abdomen,” says Dr. Piña.
