Is Pneumonia Life-Threatening?

Can You Die from Pneumonia? What You Need to Know

Pneumonia is the inflammation of the air sacs in one’s lungs due to viral, bacterial, or fungal infections. It can affect one or both lungs and fill them with pus or fluid. Although it can be very dangerous for some groups, many healthy adults and children recover completely with timely treatment.

High-risk groups include adults >65, infants <2 years, immunocompromised individuals (e.g., HIV, chemotherapy patients), smokers, and those with chronic lung/heart disease or unvaccinated status (e.g., against pneumococcus or influenza). If pneumonia is not treated promptly and efficiently, it can result in organ failure, sepsis, respiratory failure, and even death.

Early detection and medical intervention are essential to prevent life-threatening consequences of pneumonia. Read on to learn more about it!

Recognising Symptoms of Pneumonia

Following symptoms of Pneumonia includes:

• Abnormal body temperature including fever, chills or lesser than normal body temperature in people with weak immune systems or in older adults
• Difficulty in breathing or shortness of breathing
• fatigue or tiredness
• Nausea, diarrhoea or vomiting
• Confusion especially in older adults
• Chest pain while cough or breathing

What are the Signs of Walking Pneumonia?

Walking pneumonia, also known as atypical pneumonia, is a milder form of lung infection, often caused by Mycoplasma pneumoniae. Its symptoms are usually less severe and may develop gradually.

Here are some of the common signs of walking pneumonia:

• Low-grade fever (about 101°F or 38.5°C or lower)
• A persistent cough that can last weeks or even months
• Fatigue and malaise
• Headache, chills, sore throat, and other cold or flu-like symptoms
• Chest pain or stomach pain
• Loss of appetite or poor feeding in infants
• Mild ear pain, rash, or joint pain in some cases
• Fast breathing, grunting, or wheezing sounds
• Retractions (areas below or between the ribs or in the neck sink in with each breath), indicating laboured breathing

As symptoms are mild, people with walking pneumonia often continue daily activities, but it's essential to rest and seek treatment to prevent the worsening of the illness.

Does Pneumonia Damage Your Lungs?

Pneumonia can cause both short-term and long-term damage to the lungs, especially if the infection is severe or left untreated. Here is a detailed overview:

• In the acute phase, pneumonia impairs the lungs’ ability to exchange gases, sometimes leading to respiratory failure.
• Severe infections can result in complications such as lung abscesses, pleural effusion (fluid around the lungs), or permanent scarring. Permanent damage is rare in healthy adults; childhood pneumonia is more strongly linked to long-term sequelae.
• In the long term, especially in young children or those who experience severe or repeated pneumonia, there is a risk of developing chronic lung diseases.
• Studies have shown that childhood pneumonia can increase the risk of restrictive or obstructive lung diseases, asthma, bronchiectasis, and even chronic obstructive pulmonary disease (COPD) later in life.
• The risk is higher for those hospitalized for pneumonia or infections caused by certain pathogens, such as adenovirus.

However, many people have recovered without any long-lasting lung damage by following proper treatment and follow-up care.

How Long Does It Take to Recover from Pneumonia?

Recovery from pneumonia depends on the following factors:

• Age
• General health
• The intensity of the infection

The fever usually goes away within a week, and most people feel better after that. Chest pain and mucus production usually subside by four weeks. Coughing and breathing problems usually disappear after six weeks, though some people may still feel exhausted.

Recovery can be a long process. While the infection itself may clear in weeks, fatigue and weakness can persist for many months, especially in older adults. It may take six months to a year or longer to feel fully recovered.

Possible Complications with Pneumonia

Pneumonia can cause serious complications, especially in individuals with weak immunity, children, older individuals, and those suffering from chronic illnesses. These complications arise when the infection spreads, or the body fails to respond accordingly.

The most dangerous complication of pneumonia is respiratory failure. In this condition, the lungs cannot supply enough oxygen to the body. Here are the common types:

1. Sepsis: It is a widespread infection that can cause organ failure.
2. Bacteremia: In this condition, bacteria enter the bloodstream, causing further complications.  

Pneumonia can also lead to the following complications:

• Lung abscesses (pockets of pus in the lung)
• Kidney failure
• Heart rhythm disorders
• Pleural effusion (fluid around the lungs)
• Acute respiratory distress syndrome (ARDS)
• Chronic lung damage, like bronchiectasis

You can identify the complications by looking for the following symptoms:

• Severe shortness of breath
• Confusion or loss of consciousness
• Rapid or irregular heartbeat
• Bluish skin or lips
• Swelling in the legs or ankles
• Persistent high fever
• Chest pain
• Extreme fatigue or weakness

Recent research has also highlighted the body’s remarkable ability to repair lung tissue after pneumonia, especially with the help of immune cells called macrophages. They help clear infection and promote tissue repair, and new therapies may further enhance lung recovery in the future. 

Preventing Life-threatening Pneumonias

You can help to prevent life-threatening pneumonias infection through following precautions:

• Monitoring Your Health
• Practicing Good Hygiene
• Getting vaccinated
• Living a Healthy Lifestyle
