Acute Bronchitis

11 min read

Acute bronchitis is a type of lower respiratory tract infection that affects the bronchial tubes, which are the airways that carry air to and from the lungs. It is usually caused by a virus, but can also be caused by bacteria or other irritants. Symptoms of acute bronchitis include a cough that produces mucus, chest discomfort, and a feeling of tightness in the chest. Most cases of acute bronchitis resolve on their own without medical treatment.

Causes of Acute Bronchitis

Acute bronchitis is usually caused by a virus, such as the common cold or influenza. It can also be caused by bacteria, such as Streptococcus pneumoniae, Haemophilus influenzae, or Mycoplasma pneumoniae. In some cases, acute bronchitis can be caused by irritants, such as smoke, dust, fumes, or air pollution.

Diagnosis of Acute Bronchitis

Acute bronchitis is usually diagnosed based on a physical exam and a review of the patient's medical history. The doctor may also order tests, such as a chest X-ray or a sputum culture, to rule out other conditions, such as pneumonia.

Complications of Acute Bronchitis

In some cases, acute bronchitis can lead to complications, such as pneumonia, asthma, or chronic bronchitis. It is important to seek medical attention if you experience any of the following symptoms: difficulty breathing, chest pain, fever, or a persistent cough.

Symptoms

Cough

The most common symptom of acute bronchitis is a persistent cough. This cough may produce mucus, which can be clear, white, yellow, or green in color. The cough may last for several weeks, and can be accompanied by chest pain or tightness.

Shortness of Breath

Shortness of breath is another common symptom of acute bronchitis. This can be caused by the inflammation of the bronchial tubes, which can make it difficult to breathe. This symptom may be worse when exercising or when exposed to cold air.

Wheezing

Wheezing is a whistling sound that is caused by narrowed airways. It is a common symptom of acute bronchitis, and can be heard when breathing out. Wheezing can be a sign of a more serious condition, so it is important to seek medical attention if it occurs.

Low-Grade Fever

A low-grade fever is another symptom of acute bronchitis. This fever may be accompanied by chills and body aches. It is important to seek medical attention if the fever is higher than 101°F (38.3°C).

Fatigue

Fatigue is a common symptom of acute bronchitis. This can be caused by the body’s effort to fight off the infection. It is important to get plenty of rest and drink plenty of fluids to help the body recover.

Causes

Viral Infections

The most common cause of acute bronchitis is a viral infection. Viruses such as the common cold, influenza, and other respiratory viruses can cause inflammation of the bronchial tubes. This inflammation leads to the production of excess mucus, which can cause coughing, wheezing, and difficulty breathing.

Bacterial Infections

Bacterial infections can also cause acute bronchitis. Bacteria such as Streptococcus pneumoniae, Haemophilus influenzae, and Mycoplasma pneumoniae can cause inflammation of the bronchial tubes. These infections can lead to more serious health problems, such as pneumonia, if left untreated.

Environmental Irritants

Environmental irritants such as smoke, dust, and chemical fumes can also cause acute bronchitis. These irritants can irritate the bronchial tubes and cause inflammation, leading to coughing, wheezing, and difficulty breathing.

Allergies

Allergies can also cause acute bronchitis. Allergens such as pollen, dust mites, and pet dander can cause inflammation of the bronchial tubes, leading to coughing, wheezing, and difficulty breathing.

Getting a Diagnosis

Symptoms of Acute Bronchitis

The most common symptoms of acute bronchitis include a persistent cough, chest pain, shortness of breath, and a feeling of tightness in the chest. Other symptoms may include a fever, fatigue, and a sore throat. In some cases, wheezing may also be present.

Diagnostic Tests

In order to diagnose acute bronchitis, a doctor may perform a physical examination and ask the patient about their medical history. The doctor may also order a chest X-ray to look for signs of infection or inflammation. In some cases, a sputum culture may be taken to determine if the infection is caused by a virus, bacteria, or fungus. Blood tests may also be ordered to check for signs of infection.

Treatment of Acute Bronchitis

Treatment of acute bronchitis typically involves rest, fluids, and over-the-counter medications to reduce fever and pain. In some cases, antibiotics may be prescribed if the infection is caused by bacteria. Inhaled medications may also be prescribed to help open the airways and reduce inflammation.

Questions for Your Doctor

Symptoms

Be sure to tell your doctor about all of your symptoms, including any that may seem unrelated to your bronchitis. This will help your doctor make an accurate diagnosis and determine the best course of treatment.

Medical History

Your doctor will also want to know about your medical history, including any other conditions you may have and any medications you are taking. This information can help your doctor determine the cause of your bronchitis and the best treatment plan.

Treatment Options

Your doctor may recommend a variety of treatments for acute bronchitis, including antibiotics, over-the-counter medications, and lifestyle changes. Be sure to ask your doctor about the risks and benefits of each treatment option so you can make an informed decision.

Follow-up Care

Your doctor may also recommend follow-up care to monitor your progress and ensure that your condition is improving. Be sure to ask your doctor about any follow-up tests or appointments that may be necessary.

Treatment

Antibiotics

Antibiotics are not usually prescribed for acute bronchitis because the condition is usually caused by a virus, which antibiotics cannot treat. However, if a bacterial infection is present, antibiotics may be prescribed. Common antibiotics used to treat acute bronchitis include amoxicillin, azithromycin, and doxycycline.

Cough Suppressants

Cough suppressants, such as dextromethorphan, can be used to reduce the frequency and severity of coughing. These medications should not be used for more than a few days, as they can cause side effects such as drowsiness and dizziness.

Expectorants

Expectorants, such as guaifenesin, can be used to thin mucus and make it easier to cough up. These medications should not be used for more than a few days, as they can cause side effects such as nausea and vomiting.

Inhaled Medications

Inhaled medications, such as albuterol, can be used to open the airways and make it easier to breathe. These medications should not be used for more than a few days, as they can cause side effects such as rapid heartbeat and shakiness.

Other Treatments

Other treatments for acute bronchitis include rest, fluids, and over-the-counter medications to relieve symptoms such as fever and pain. In some cases, a humidifier may be used to help loosen mucus and make it easier to cough up. In severe cases, a doctor may prescribe oral or intravenous steroids to reduce inflammation.

Drugs & Medications

Over-the-Counter Medications

Over-the-counter medications can help relieve the symptoms of acute bronchitis. These include pain relievers such as ibuprofen or acetaminophen to reduce fever and pain. Cough suppressants such as dextromethorphan can help reduce coughing. Decongestants such as pseudoephedrine can help reduce congestion. Expectorants such as guaifenesin can help thin mucus and make it easier to cough up.

Prescription Medications

In some cases, antibiotics may be prescribed to treat bacterial infections that cause acute bronchitis. These antibiotics may be taken orally or inhaled through a nebulizer. Inhaled corticosteroids may also be prescribed to reduce inflammation in the airways. Bronchodilators such as albuterol can help open the airways and make it easier to breathe.

Other Treatments

In addition to medications, other treatments may be recommended to help relieve symptoms of acute bronchitis. These include drinking plenty of fluids to help thin mucus and make it easier to cough up. A humidifier or steam inhalation can also help reduce congestion. Avoiding irritants such as smoke and other pollutants can help reduce symptoms. If symptoms persist or worsen, it is important to see a doctor for further evaluation.
