Shortness Of Breath After 1 Flight Of Stairs Symptoms

Experiencing shortness of breath after climbing one flight of stairs may be occurring simply due to fatigue. However, in order to rule out any underlying conditions, let's examine the following symptoms, causes, and potential treatments your medical provider may discuss with you when you seek care.

Shortness of breath, also referred to as dyspnea, can best be described as breathing discomfort. Some people with shortness of breath describe it as chest tightness or difficulty catching their breath, while others may feel like they cannot get enough air.

Common accompanying symptoms of shortness of breath after walking up stairs

Shortness of breath can be frightening, especially because it is can often be associated with symptoms such as [1,4]:

Is shortness of breath ever normal?

It is important to note that shortness of breath can be a normal physiological response in certain situations. For example, during intense exercise, the body responds by increasing the breathing rate to remove carbon dioxide (a waste product created when energy is produced), bring in oxygen, and maintain blood flow to the working muscles.

However, dyspnea during activities that you once completed without symptoms should create concern. For example, if you could walk up one flight of stairs or walk two blocks without experiencing shortness of breath, but now notice symptoms while doing these activities, you should make an appointment with your healthcare provider. Furthermore, if you experience dyspnea in the absence of physical activity, seek medical treatment promptly as well.

Shortness Of Breath After 1 Flight Of Stairs Causes

The causes of shortness of breath are varied and can range in severity from short-lived problems to chronic, even life-threatening conditions. It is very important to make an appointment with your healthcare provider if you notice shortness of breath after activity that you once found easy or normal. The causes of dyspnea can be categorized into the following groups:

Pulmonary/Respiratory causes

The respiratory system is a complex interplay of components including the lungs, brain, and chest muscles responsible for transferring carbon dioxide from the body into the atmosphere while bringing oxygen from the atmosphere into the blood. Any process that disrupts or damages this system can result in dyspnea [4,6].

  • Obstructive: The main component of the respiratory system is the lungs and a system of branching windpipes (bronchi) and blood vessels. Obstruction of this system due to causes such as blood clots in the arteries or foreign objects obstructing the airways can result in acute (immediate) symptoms of dyspnea.
  • Inflammatory: Inflammation of the lungs due to irritants such as infections, allergens, and even chronic conditions such as asthma can result in dyspnea due to irritation and acute injury of the lungs. For example, pneumonia inflames the airways and fills the air sacs of the lungs with fluid, impairing proper oxygen exchange to the blood, resulting in shortness of breath. Furthermore, in conditions such as chronic obstructive pulmonary disease (COPD), the airways can become inflamed, narrowed and damaged over time due to activities such as smoking and result in dyspnea [2].

Cardiac causes

The cardiovascular system is responsible for pumping oxygenated blood from the lungs to all of the tissues in the body in an effective and timely manner. Any process that disrupts or damages this system can also result in shortness of breath.

  • Obstructive: In order for the heart to pump blood effectively, it needs its own blood supply as well. A complex network of arteries supplies the heart with blood and the proper amount of oxygen and nutrients it requires to function. In certain conditions such as atherosclerosis (hardening or narrowing of the arteries), these vessels can become blocked and limit blood flow to the heart. When blood flow is limited, the heart muscle can become severely injured and result in a myocardial infarction, or heart attack. Heart attacks cause dyspnea because the heart is suddenly not pumping blood back to the lungs or to the body properly.
  • Weakness: Similarly, the heart's ability to pump blood to the body can be compromised because the heart muscles become functionally weak. This condition is known as heart failure or congestive heart failure (CHF). Heart failure is a chronic condition and causes dyspnea because the heart does not properly pump blood forward to the body, and pressure and fluid builds up the lungs causing congestion and other problems such as swelling.

Environmental causes

Environmental causes can be related to lifestyle habits or certain exposures.

  • Deconditioning: A sedentary lifestyle that does not involve much physical activity can result in dyspnea even with small tasks. Your heart is rarely working at its maximal output, so over time, this maximum cardiac output lessens and the heart needs to work harder and beat faster in order to pump the necessary blood needed to oxygenate the muscles and complete activities.
  • Weight: Individuals who are overweight can experience dyspnea due to reasons related to deconditioning, but weight gain also related to pregnancy can result in shortness of breath. Pregnancy changes a woman's circulatory and respiratory systems in order to account for the growing fetus, and dyspnea is often a common result.

9 Possible Shortness Of Breath After 1 Flight Of Stairs Conditions

The list below shows results from the use of our quiz by Buoy users who experienced shortness of breath after 1 flight of stairs. This list does not constitute medical advice and may not accurately represent what you have.

Chronic obstructive pulmonary disease (copd)

Chronic obstructive pulmonary disease (COPD) is a progressive inflammation of the lungs that makes breathing difficult. It is caused by long-term exposure to irritating gases and/or dust particles, most often cigarette smoke.

Symptoms may take years to develop. They include a chronic cough with mucus (sputum), wheezing, chest tightness, fatigue, constant colds, swollen ankles, and cyanosis (blue tinge to the lips and/or fingernails.) Depression is often a factor due to reduced quality of life.

Treatment is important because there is a greater risk of heart disease and lung cancer in COPD patients. Though the condition cannot be cured, it can be managed to reduce risks and allow good quality of life.

COPD is commonly misdiagnosed and so careful testing is done. Diagnosis is made through patient history; physical examination; lung function tests; blood tests; and chest x-ray or CT scan.

Treatment involves quitting smoking and avoiding exposure to other lung irritants; use of inhalers to ease symptoms; steroids; lung therapies; and getting influenza and pneumonia vaccines as recommended.

Aortic valve regurgitation

Aortic valve regurgitation occurs when the aortic valve one of the four valves in the heart fails to function properly and allows blood to flow backward through it. When some blood flows back from the aorta into the heart, it puts pressure on the heart and...

Iron deficiency anemia

Iron deficiency anemia is a condition in which the body does not have enough iron to form hemoglobin, the protein in red blood cells that carries oxygen throughout the body.

The condition can be caused by acute blood loss through injury, surgery, or childbirth;chronic b...

Viral pneumonia

Viral pneumonia, also called "viral walking pneumonia," is an infection of the lung tissue with influenza ("flu") or other viruses.

These viruses spread through the air when an infected person coughs or sneezes.

Those with weakened immune systems are most susceptible, such as young children, the elderly, and anyone receiving chemotherapy or organ transplant medications.

Symptoms may be mild at first. Most common are cough showing mucus or blood; high fever with shaking chills; shortness of breath; headache; fatigue; and sharp chest pain on deep breathing or coughing.

Medical care is needed right away. If not treated, viral pneumonia can lead to respiratory and organ failure.

Diagnosis is made through chest x-ray. A blood draw or nasal swab may be done for further testing.

Antibiotics do not work against viruses and will not help viral pneumonia. Treatment involves antiviral drugs, corticosteroids, oxygen, pain/fever reducers such as ibuprofen, and fluids. IV (intravenous) fluids may be needed to prevent dehydration.

Prevention consists of flu shots as well as frequent and thorough handwashing.

Atrial fibrillation

Atrial fibrillation (A-fib) is an abnormal heart rhythm (arrhythmia) characterized by a rapid rate and irregular rhythm that feels like the heart is quivering. It can lead to chest discomfort, shortness of breath, lightheadedness, and the formation of blood clots, which can cause...

Narrowing of the aortic valve

Narrowing of the aortic valve is also called aortic valve stenosis, aortic stenosis, or AS. The aortic valve controls the flow of blood from the heart into the aorta, the body's main artery. If the aortic valve is abnormally narrow, the blood being pushed through it is blocked. Pressure may build up within the heart, causing damage.

AS may be caused by a congenital malformation of the valve, or by calcium deposits and/or the scarring that occurs as a person ages.

Symptoms may not appear right away. There will be chest pain with the feeling of pounding heartbeat, as well as shortness of breath with fatigue, lightheadedness, or even fainting.

It is important to see a medical provider for these symptoms, since AS can lead to stroke, blood clots, and heart failure.

Diagnosis is made through physical examination, echocardiogram, CT scan, and sometimes a stress test.

Treatment may simply involve monitoring and medication, while making lifestyle improvements in diet, exercise, weight, and smoking. Surgery to repair or replace the faulty aortic valve may be recommended.

Rarity: Uncommon

Top Symptoms: fatigue, shortness of breath, chest pain, shortness of breath on exertion, decreased exercise tolerance

Urgency: Hospital emergency room


Myocarditis is an inflammation of the heart muscle, also called the myocardium.

It is a rare complication of any viral, bacterial, parasitic, or fungal infection. Reaction to drugs, medications, chemicals, or even radiation can bring about myocarditis.

Anyone with a weakened immune system or pre-existing heart condition is susceptible.

Symptoms include fatigue, chest pain, and shortness of breath, especially following a viral upper respiratory illness. Swelling of the feet and legs from poor circulation may be seen.

If symptoms are severe, take the patient to the emergency room or call 9-1-1. Myocarditis weakens the heart so that it cannot pump blood as it should. Blood clots, stroke, heart attack, abnormal heart rhythm (arrhythmia,) and sudden cardiac death can result without treatment.

Diagnosis is made by electrocardiogram (ECG,) chest x-ray, MRI, echocardiogram, and blood tests.

Short-term treatment is with rest and medication, depending on what kind of illness brought about the myocarditis. Sometimes, devices to support the heartbeat may be surgically implanted.

Long-term treatment may involve medicines such as ACE inhibitors, ARBs, beta blockers, and diuretics.

Rarity: Rare

Top Symptoms: fatigue, headache, shortness of breath, muscle aches, chest pain

Urgency: Hospital emergency room

Chest pain from reduced cardiac blood flow (angina pectoris)

Angina pectoris is chest pain that is felt when heart muscle needs more blood than it is currently getting. This may result from coronary artery disease (CAD). CAD happens when the arteries that supply blood to heart muscle become hardened and narrowed. This is due to the buildup of cholesterol and other material, called plaque, on their inner walls.

Rarity: Common

Top Symptoms: chest pain, chest pain, tight, heavy, squeezing chest pain, moderate chest pain, deep chest pain, behind the breast bone

Symptoms that always occur with chest pain from reduced cardiac blood flow (angina pectoris): chest pain

Symptoms that never occur with chest pain from reduced cardiac blood flow (angina pectoris): productive cough

Shortness Of Breath After 1 Flight Of Stairs Treatments and Relief

When to see a doctor

Because the causes of dyspnea are so varied, it can be treated in many different ways depending on the cause. Furthermore, dyspnea is often the result of a combination of causes (most often pulmonary and cardiovascular) versus one singular cause and can also be acute (short-lasting) or chronic (long-term). Your physician will work closely with you in order to develop the appropriate treatment regimen for you. Your physician may suggest:

  • Antibiotics: If your dyspnea is due to a lung infection, your physician will provide the appropriate antibiotics to treat the causative bacteria. Viral causes of pneumonia will not be treated with antibiotics and are best managed with supportive care (fluids, bed rest, etc.).
  • Steroids: Steroids in the setting of dyspnea are used due to their anti-inflammatory properties and can help with the inflammation caused by diseases such as asthma and COPD. These medications are often given via inhalers but can also be given in pill form or injected depending on acuity.
  • Bronchodilators: Bronchodilators are medications that open the airways and are commonly used to treat COPD and asthma. They are often given via an inhaler or nebulizer.


Fortunately, there are many things you can do at home to both prevent and help treat conditions related to shortness of breath.

  • Do not smoke: Smoking is the number one cause of diseases such as COPD and can irritate conditions such as asthma and pneumonia. Quitting smoking can go a long way in helping prevent and relieve symptoms.
  • Exercise: Exercise is key in keeping the heart strong and allowing it to pump effectively through various activities. The American Heart Association recommends at least 30 minutes of moderate-intensity aerobic exercise for at least five days a week for adults [7].

When it is an emergency

Seek emergency medical attention if you notice the following symptoms:

  • You have shortness of breath and think you are having a heart attack: Due to chest tightness, nausea, or sweating
  • You have severe shortness of breath: Meaning its even hard to breathe when you are sitting still
  • An allergic reaction with shortness of breath

FAQs About Shortness Of Breath After 1 Flight Of Stairs

Here are some frequently asked questions about shortness of breath after 1 flight of stairs.

Can I exercise with a lung condition?

Yes, in fact, exercising with a lung condition can often help improve symptoms [5]. However, it is important to always consult with your healthcare provider before starting an exercise regimen. Exercise programs must be adapted to your level of physical activity and change as you improve in stamina and experience fewer symptoms.

Can I grow out of my asthma?

Many children do not completely "grow out" of their asthma [8]. Asthma symptoms can improve or worsen over time, and for some adults, symptoms may not be triggered for many reasons [3,8]. However, symptoms such as coughing and wheezing can also occur due to allergens, weather changes and other conditions such as pneumonia, so it is important to follow-up with your physician if you had asthma and believe it is recurring.

Is dyspnea life-threatening?

Dyspnea can be life-threatening in the setting of conditions such as a myocardial infarction (a heart attack) or a pulmonary embolism (a blood clot in the arteries of the lungs). This is why shortness of breath should never be an ignored symptom, especially if it occurs during activities you once completed without dyspnea.

Is pneumonia contagious?

Yes, pneumonia is a lung infection that can be caused by bacteria, fungi or viruses. Some of these pathogens can spread from person-to-person, especially via respiratory droplets that spread through the air from coughing and sneezing. This makes it very important to practice good hygiene such as washing your hands, covering your mouth, and not sharing things that come in contact with your mouth with others.

How is shortness of breath treated?

Shortness of breath is treated in different ways and is highly dependent on the cause. Your healthcare provider will discuss multiple options that are most appropriate for the cause of your symptoms (these options may include oxygen, inhaled bronchodilators or steroids, antibiotics, etc.) and develop a treatment plan tailored to you.

Questions Your Doctor May Ask About Shortness Of Breath After 1 Flight Of Stairs

To diagnose this condition, your doctor would likely ask the following questions:

  • Have you been feeling more tired than usual, lethargic or fatigued despite sleeping a normal amount?
