Asthma is normally diagnosed by means of three factors: physical examination, medical history, and results of breathing tests. If a person is deducted with asthma, then they should determine their level of severity such as periodic, mild, less intense, or severe. First the physician normally checks the medical history of the patient. A detail family history helps the physician to make accurate diagnosis of asthma and the patient should also produce the record of personal allergies for more accurate result. The allergies and symptoms include coughing, wheezing, chest tightness, worsening symptoms due to cold air, breathing difficulty, worsening symptoms during night, symptoms due to allergens and symptoms while doing exercise.
It is even good to note down the health conditions that often interfere with asthma such as sinus infections, physiological stress, running nose, sleep apnea, and acid reflux disease. Next step to diagnose is the physical examination and it is normally concentrated on the chest, upper respiratory tract, and skin. The doctors normally use stethoscope to find out the signs of asthma when a person breathe. The wheezing or high whistling sound is the signs of having asthma or inflamed airway. Other than this physician also checks running nose, nasal polyps, swollen nasal passages, along with the skin examination for any allergies such as hives and eczema.
Normally, physical symptoms are not present in the asthma sufferers. After this procedure, certain tests are performed to confirm the presence of asthma such as lung function test, spirometry, and forced vital capacity. Lung function test measure the amount of air that flows in and out of the lungs. The measurements of all three tests are taken and compared with the results of the normal people to find out whether the person is suffering from asthma.
There are also other tests conducted to check asthma such as challenge tests, allergy tests, and other tests to check whether the sufferers have other diseases such as heartburn, sleep apnea, reflux disease, sinusitis, hay fever, airway tumors, bronchitis, blood clot in the lungs, dysfunction of vocal cord, lung infection, congestive heart failure, and viral infection.
