Health Conditions That Mimic Asthma
Just because you have symptoms of asthma, such as wheezing, coughing, or difficulty breathing does not mean that you have asthma. Other health conditions have symptoms that may mimic asthma symptoms. Let’s look at some common "asthma mimics."
Health Conditions That Mimic Asthma Symptoms
Because other health conditions may appear to be asthma and mimic asthma symptoms, your doctor will do a thorough exam run any necessary tests to be sure your symptoms are due to asthma.
Conditions that can mimic asthma include:
- Sinusitis: Also called a sinus infection; an inflammation or swelling of the sinuses. Sinusitis and asthma often coexist.
- Myocardial ischemia: A disease of heart function characterized by inadequate blood flow to the muscle tissue of the heart.
- Pulmonary embolism: A blood clot in the pulmonary artery in the lungs.
- Gastroesophageal reflux disease (GERD): A disorder in which stomach contents and acid flow back into the esophagus, causing frequent heartburn. Heartburn can cause asthma symptoms.
- Angina:Chest pain due to lack of blood flow to the heart.
- Chronic obstructive pulmonary disease (COPD): A general term for several lung diseases, most commonly emphysema and chronic bronchitis, most commonly caused by cigarette smoking.
- Chronic bronchitis: Irritation and inflammation (swelling) of the lining in the air passages, also a form of COPD from smoking.
- Congestive heart failure: A heart condition in which the heart does not pump correctly, leading to a buildup of fluid in the lungs.
- Bronchiectasis: Lung disease characterized by injury to the walls of the airways in the lungs; main cause is repeated infection.
- Upper airflow obstruction: A condition in which the flow of air is blocked by something, including enlarged thyroid glands or tumors.
- Vocal cord dysfunction: A condition in which the larynx (voice box) muscles close rapidly, causing difficulties in breathing.
- Vocal cord paralysis: Loss of function of vocal cords.
- Bronchogenic carcinoma:Lung cancer.
- Aspiration: Accidentally breathing food or other matter into the lungs.
- Pulmonary aspergillosis: Fungal infection of lung tissues.
- Respiratory syncytial virus (RSV): This virus can cause wheezing and pneumonia in children and may lead to childhood asthma.
