Chẩn đoán hen suyễn: 4 vấn đề liên quan đến chứng khó thở cần lưu ý kẻo nhầm lẫn

Chẩn đoán hen suyễn: 4 vấn đề liên quan đến chứng khó thở cần lưu ý kẻo nhầm lẫn

The diagnosis of asthma is often difficult because the symptoms are quite common and easily confused with the signs of many other diseases.

An accurate diagnosis of asthma is an important factor in timely and effective treatment. If the diagnosis is wrong, the use of drugs will not work, leading to costly costs and many other negative health consequences. So how do you distinguish asthma from other diseases for early detection and timely treatment?

Factors to help you realize you may not have asthma

Here are four factors associated with shortness of breath that many people mistake for asthma.

1. You have signs of shortness of breath but no chest pain or wheezing

Although shortness of breath is one of the symptoms of asthma, it is often accompanied by wheezing and chest pain. Even if you have all of the above 3 symptoms, you cannot say for sure that it is asthma. Therefore, you should get tested to diagnose asthma accurately.

2. You have a BMI higher than 30

According to a study, asthma is more likely to be misdiagnosed in overweight and obese people . Because obesity is very easy to cause breathing difficulties for patients. Therefore, to accurately diagnose asthma, patients need to pay attention to this factor.

3. You take asthma medicine but it doesn’t work

If you’re already taking asthma medications to control your asthma, but they don’t work, it could be a sign that you have something else other than asthma. At this point, you should talk to your doctor to find out the specific cause.

4. Prednisone doesn’t work

If your doctor asks you to take prednisone (steroid tablets) and they don’t work, you probably don’t have asthma. This shortness of breath is sometimes caused by other conditions such as heart disease or pneumonia. However, this could also be because you are not responding well to the medication. In either case, you will need to go to the hospital to be checked by a doctor.

Early symptoms of asthma

For early detection and accurate asthma diagnosis, you also need to understand the early symptoms of the disease. These symptoms can vary. They will appear before the common symptoms of asthma and are signs that the disease is getting worse.

In general, the early signs of asthma are usually not too severe, so you can still maintain daily activities and tend to subjectively ignore them. If you recognize the above signs, you can prevent an asthma attack and prevent it from getting worse. Early warning signs include:

  • Cough frequently, especially at night
  • Shortness of breath
  • Feeling tired when exercising
  • Wheezing or coughing after exercise
  • Feeling tired or sad
  • Lung function decreases or changes to alarming levels
  • Signs of a cold or allergy ( sneezing , coughing, indigestion, sore throat and headache)
  • Difficulty sleeping.

Symptoms of an asthma attack

During an asthma attack , the muscle groups around the trachea contract violently. During this procedure, the wall of the trachea becomes swollen and inflamed, and the cells around the wall secrete a thicker, thicker mucus than usual.

Factors such as bronchospasm, inflammation, and mucus production all cause symptoms such as shortness of breath, wheezing, and coughing, making it difficult for people to perform daily activities.

Other symptoms of asthma include:

  • Wheezing when inhaling and exhaling
  • Cough doesn’t stop
  • Rapidly breath
  • Chest pain
  • Chest and neck spasms
  • Difficulty talking
  • Concerned
  • Sweat
  • Pale lips or fingers.

The severity of asthma can change rapidly. Therefore, if you notice the above abnormal symptoms, you should immediately seek out reputable specialist clinics for an accurate diagnosis of asthma.

How to diagnose asthma?

If you notice the above symptoms of asthma, you should immediately see your doctor for an examination and tests to diagnose the disease. Some of the tests commonly ordered by doctors are:

  • FeNO test: You will be asked to breathe into a nitric oxide level meter to detect inflammation in the lungs.
  • Sspirometer : You will have to breathe into a machine called a spirometer. This machine measures your respiratory function, breathing rate, and the amount of air you breathe.
  • Peak flow test: This is a test that measures your breathing rate. You will have to take a full breath, then blow into the peak flow meter. This method helps your doctor check your respiratory function and diagnose asthma.

After being diagnosed with asthma, your doctor may also order a chest X-ray or allergy testing to see if your symptoms are caused by allergies. At this time, depending on the condition of the disease, the doctor will prescribe the appropriate treatment measures and drugs for the patient.
