Symptoms of a Lung Infection: Causes & Treatments

Symptoms of a Lung Infection: Causes & Treatments    



A lung infection occurs when disease-causing microbe damage and inflames the airways or tissues of the lungs due to immune cells accumulating.


Viruses, bacteria, fungus, and parasites are all possible causes of lung infections. It's possible that more than one kind of microbe is to blame in certain circumstances. Viral bronchitis may progress to bacterial pneumonia, for instance.


Any age may be affected by a lung infection. However, particular illnesses are more frequent at specific ages. It is possible for them to impact the airways (bronchi, bronchioles, alveoli) of any size (bronchi, bronchioles, alveoli).




A lung infection might have subtle symptoms or be life-threatening. Your age, general health, and the kind of illness (virus, bacterium, or fungus) are all considerations. Similar to a cold and flu, but with more severe lung infection symptoms.



The following are the most frequent signs and symptoms of a lung infection:


  1. Coughing up a lot of mucous


Coughing helps your body eliminate the mucus created by inflamed airways and lungs. Blood may also be found in this mucous.With bronchitis or pneumonia, thick mucus may come out of your lungs in a variety of colors:


  • Clear
  • White
  • Green
  • Yellowish-grey


A cough might persist for weeks even when the rest of your symptoms have subsided.


  1. Stabbing pains in the chest


A lung infection may produce acute or stabbing chest discomfort. When coughing or inhaling deeply, the chest discomfort tends to become worse. The mid to upper back is where the acute aches may sometimes be felt.


  1. The flu.


As your body attempts to fight off the infection, you will have a fever. The average human body temperature is 98.6°F (37°C).


A hazardous 105°F (40.5°C) fever is possible if you have a bacterial lung infection.


A fever of more than 102°F (38.9°C) is typically accompanied by a wide range of additional symptoms, including:


  • sweating
  • chills
  • Aches and pains in the muscles
  • Dehydration
  • Headache
  • Weakness


A doctor should be called if your temperature rises above 102 degrees Fahrenheit (38.9 degrees Celsius) or lasts more than three days.


  1. Aches and pains


When you have a lung infection, you may have pain in your muscles and back. It's referred to as "myalgia." As a side effect of a disease, your muscles may become inflamed, resulting in pain throughout your body.


5.An itchy, watery nose


Flu-like symptoms, such as coughing and sneezing, might be signs of bronchitis.


  1. Breathlessness


To be short of breath, one must have difficulty taking a full breath in. Any time you're experiencing difficulty breathing, you should seek medical attention.


  1. Tiredness


You'll feel sluggish and exhausted as your body tries to fight off an infection. This is a critical moment to take a break and recharge your batteries.




It's common to hear a high-pitched whistling sound or "wheezing" as you exhale. The narrowing of the airways or inflammation is the cause of this.


  1. Skin or lips that looks bluish


Lack of oxygen might cause your lips or nails to pale blue.


10g. Lung noises such as crackling or rattling.


A cracking sound at the lungs' base, also known as bibasilar crackles, is one of the obvious symptoms of a lung infection. Using a stethoscope, a doctor can hear these noises.






The main lung infection causes is Lung diseases such as bronchitis, pneumonia, and bronchiolitis come in various shapes and sizes. Viruses and bacteria are usually to blame. Bronchitis may be caused by a variety of bacteria, including:


The influenza virus and other respiratory syncytial viruses (RSV)


Chlamydia pneumonia, mycoplasma pneumonia, and borrelia pertussis are some examples of pathogens to avoid.


The following types of microorganisms often cause pneumonia:


Infections caused by germs like Streptococcus pneumonia, Haemophilus influenza, and Mycoplasma pneumonia, among others


Influenza and respiratory syncytial virus (RSV)


Pneumocystis jirovecii, Aspergillus, and Histoplasma capsulatum are all fungi that may cause lung infections.


Immunosuppressed individuals, such as those with certain forms of cancer or HIV, or those using immunosuppressive medicines, are more likely to develop a fungal lung infection.





To begin, a doctor will gather information about your health and inquire about your current symptoms. You could be questioned about your job, where you've recently been, or whether you've been around animals. Your temperature will be taken, and a stethoscope will be used to listen to your chest for crackling noises.



Lung infection may also be detected by:


  • A chest X-ray or CT scan is an example of imaging.
  • Bronchoscopy, EBUS, Thoracoscopy.
  • For example, you can see how much and rapidly you're breathing using spirometry.
  • Pulse oximetry to check your blood's oxygen content
  • Collect nasal discharge or a sample of mucus for testing addition to the swab of the throat
  • Complete blood count should be performed (CBC)
  • Blood test
  • Sputum Testing




Depending on the illness and the organism that caused it, therapy for a lung infection can vary, although certain medications can be utilized for most infections.


Home remedies


The following are examples of natural cures:


  • Taking acetaminophen (Tylenol) or ibuprofen (Advil)
  • The importance of getting enough sleep and drinking lots of water
  • Using a cool mist vaporizer


According to a new research study, a spoonful of honey may be the safest and most effective alternative to cough/cold medications.


Antibiotics are often required to treat a bacterial illness. Ketoconazole or voriconazole are two antifungal medications that may be used to treat a fungal lung infection. Viral infections can be treated with antiviral medications. Usually, you have to wait for your body to fight off the infection on its own before taking any action.


In the meanwhile, the following home lung infection treatment may help your body fight the illness and keep you more comfortable:


  • Decrease your fever by taking acetaminophen or ibuprofen
  • Get plenty of hydration.
  • Honey or ginger tea is a good choice.
  • Gargling with salt water
  • Get plenty of sleep
  • To add moisture to the air, use a humidifier.
  • Once the infection is gone, take any prescription medicine.


If your infection is more serious, you may have to remain in the hospital for a while to recuperate. If you're experiencing trouble breathing, you may be given antibiotics, intravenous fluids, or respiratory treatment throughout your stay.


When should you visit a physician?


If left untreated, lung infections may become life-threatening. Coughs that last longer than three weeks or that cause difficulty breathing should be taken to the doctor. Doctors in your region are available for appointments.
