What are asthma and pneumonia?

Asthma and pneumonia are two diseases that affect the lungs.

Asthma is a chronic condition. It causes periodic inflammation and narrowing of the airways. It affects the mainbronchi, which are the two tubes that branch off the trachea (windpipe). Asthma isn’t curable, but you can effectively manage it. And it can even improve over time.

Pneumonia is a lung infection. It can occur in one or bothlungs. It causes inflammation of the air sacs. It can also cause your lungs to fill with fluid. It’s possible to treat and cure pneumonia.

Although their symptoms are similar,asthmaandpneumoniaare distinct diseases that require different treatment approaches.

People who have chronic respiratory conditions such as asthma may be at higher risk of developing pneumonia.

If you have asthma and get theflu, yoursymptoms—and yourcomplications—may be worse than they are for someone who doesn’t have asthma. According to the Centers for Disease Control and Prevention (CDC) , people with asthma who get the flu are more likely to develop pneumonia as a complication.

One of thetreatmentsfor asthma is inhaled corticosteroids. According to onestudy, these medications may themselves increase the risk of respiratory infections and pneumonia.

Asthma and pneumonia both cause:

However, there are significant differences as well.

Symptoms of asthma

Asthma flare-ups can include coughing,tightness of the chest, andwheezing. If it progresses, it can speed up breathing and pulse rates. Decreased lung function can make it difficult to breathe. You may hear ahigh-pitched whistling soundwhen you breathe.

Symptomsrange from mild to severe. Asthma symptoms can last a few minutes to many hours. There may be few symptoms between asthma flare-ups (also called exacerbations).

Possibletriggersof asthma symptoms include:

Asthma may be more difficult to control if you have other chronic health problems. The risk of anacute attackis higher if you get acold, flu, or other respiratory infection.

Symptoms of pneumonia

The symptoms of pneumonia can be mild at first. You might think you have the common cold. As the infection takes hold, your cough may be accompanied bygreen, yellow, orbloodymucus.

Other symptoms include:

Pneumonia can beviralorbacterial:

  • Viral pneumoniasymptoms start out much like those of the flu and include fever,muscle pain, and dry cough. As it progresses, the cough gets worse and you may produce mucus. Shortness of breath and fever can follow.
  • Bacterial pneumoniasymptoms include a temperature that could go as high as 105°F (40.6°C). Such a high fever can lead toconfusionanddelirium. Your pulse and breathing rates may rise. Yournail bedsandlipsmay turn blue due to lack of oxygen.

Researchers aren’t sure exactly whatcausesasthma. There may be an inherited tendency to develop asthma. There may also be environmental factors.

Pneumonia can be caused by a variety of things, such as:

  • viruses, including the flu virus
  • bacteria
  • mycoplasmas
  • fungi
  • other infectious agents
  • various chemicals

Anyone can get asthma. Most people start to have symptoms during childhood. Therisk factors for asthmainclude:

  • afamily historyof asthma
  • a personal history of respiratory infections orallergies
  • exposure to airborne allergens, chemicals, or smoke

Anyone can get pneumonia, too. Having asthma may increase your risk for developing pneumonia.Smokingcan also increase your risk of pneumonia. Other risk factors include having:

If you have the symptoms of asthma, your doctor will want a complete medical history. Aphysical examincludes inspecting your nose, throat, and airways.

Your doctor will use a stethoscope tolisten to your lungsas you breathe. A whistling sound is a sign of asthma. You may also be asked to breathe into aspirometerto test yourlung function. They may alsoperform allergy tests.

If your symptoms point toward pneumonia, your doctor will probably start by listening to your lungs. One of the hallmarks of pneumonia is that your lungs make acrackling soundwhen you breathe.

In most cases, achest X-raycan confirm the diagnosis. If necessary, aCT chest scancan get a more detailed look at lung function.

You may also need blood work to make sure you’re getting enough oxygen and to get acount of your white blood cells (WBCs). Checking your mucus can also help your doctor determine what type of pneumonia you have.

Asthma requires both short-term treatment and long-term management. In most cases, doctors can treat and cure pneumonia within a short time.

Treating asthma

Asthma is a chronic disease that requires ongoing management. You should get treatment for symptom flare-ups quickly. An acute asthma attack is alife-threatening medical emergency.

If you can identify symptom triggers, you can try to avoid them. Allergy medications may also help.

You can also check your lung function with a handheldpeak flow meter. When symptoms flare up, you can use inhaled beta-2 agonists such asalbuterol(ProAir HFA, Ventolin HFA) oranticholinergicsto expand your airways.

If you havesevere asthma, you may need to usedaily medicationsto preventattacks. These may include inhaled or oral corticosteroids, long-term beta-2 agonists such as salmeterol (Severent Diskus), orsublingual tablets, which are a type of immunotherapy.

Shop for apeak flow meterto use at home.

Treating pneumonia

If you’re in good overall health,home treatmentmay be all that’s necessary. Home care should include getting plenty of rest, drinking lots of fluids to loosen phlegm, and using店头交易(OTC)的药物to control fever.

These medications may include aspirin (Bayer),ibuprofen(Advil),naproxen(Naprosyn), or acetophenazine (Tylenol). You should not give aspirin tochildren.

Warning

Children and anyone under the age of 18 should never take aspirin for an illness. This is because of the risk of a rare, but fatal, condition calledReye’s syndrome.

Coughing can be exhausting, but it’s how your body purges infection. Ask your doctor before taking cough medicine.

你的医生可能会给你开一种抗病毒药物for viral pneumonia or antibiotics for bacterial pneumonia.

Treatment can be complicated if you have other health problems, are under 5 years old, or over 65.

People with severe pneumonia may require hospitalization and may need to receive:

It’s possible to monitor and successfully manage asthma. Most people with asthma live full, active lives.

It takes from one to three weeks to fully recover from pneumonia. It can take much longer if you’re not in good overall health.

In severe cases, or without treatment, both conditions can be life-threatening.

Asthma isn’t preventable. Good disease management can cut down on asthma attacks, however.

You can get a vaccination for a type of bacterial pneumonia called pneumococcal pneumonia. Doctors recommend this vaccine for certain people at risk of developing the disease. Ask your doctor if you should get the vaccine.

You can alsoreduce your riskof getting pneumonia by:

  • washing your hands regularly to help reduce the spread of germs
  • not smoking, since tobacco use can make it more difficult for your lungs to fight off infection
  • maintaining a healthy diet
  • staying active
  • practicing good sleep hygieneto help your body recover more quickly if you are sick
  • managing your symptoms closely if you have severe asthma
