Overview

Pneumonia is an infection that inflames the small air sacs in one or both lungs. These sacs may fill with fluid, making it harder for oxygen to reach the blood. This can cause cough, fever, chest pain or difficulty breathing.

Bacteria and viruses are common causes of pneumonia. Fungi can also cause it, though less often. Pneumonia treatment depends on the cause and how unwell the person is. Many people recover at home with treatment and rest, while those with severe symptoms or low oxygen levels may need hospital care.

At Sarvodaya Hospital, the best pulmonology hospital for pneumonia treatment, doctors assess symptoms, breathing and oxygen levels to determine how serious the pneumonia is and what care the patient needs.

Pneumonia Symptoms

• A cough, with or without mucus
• Fever or chills
• Shortness of breath or faster breathing
• Chest pain when breathing deeply or coughing
• Unusual tiredness or weakness
• Poor appetite, nausea or vomiting

Pneumonia Causes

• Bacteria: Bacterial pneumonia can develop on its own or after another respiratory infection, such as flu.
• Viruses: Viruses that cause flu, COVID-19 and other respiratory illnesses can also infect the lungs.
• Fungi: Fungal pneumonia is less common and is more likely in people with a weakened immune system.
• Aspiration: Food, drink, saliva or vomit can sometimes enter the airway instead of being swallowed. This can lead to a lung infection.

Risk Factors for Pneumonia

The causes above explain how pneumonia develops. Risk factors affect how likely someone is to get it or become seriously ill.

These include:

• Older Age or Early Childhood: Older adults and young children may be more prone to lung infections.
• Smoking: Smoking makes it harder for the airways to clear mucus and germs.
• Existing Health Conditions: Pneumonia may affect someone more severely if they already have a lung condition, diabetes or heart disease.
• A Weakened Immune System: Certain illnesses and treatments reduce the body’s ability to fight infections.
• Swallowing Difficulties: Food, drink or saliva is more likely to enter the lungs when swallowing is impaired.
• Recent Hospital Care: Someone who is seriously ill in hospital may be more likely to catch pneumonia.

Having a risk factor does not mean a person will catch pneumonia, but it may affect how closely their symptoms need to be monitored.

Pneumonia Diagnosis

For a pneumonia diagnosis, the doctor asks when symptoms began and whether they are getting worse. They also check breathing, listen to the chest and review existing health conditions.

Tests can help confirm pneumonia and show how much it is affecting the person:

• Chest X-Ray: Shows areas of inflammation in the lungs and can help confirm the diagnosis.
• Pulse Oximetry: A small sensor placed on a finger measures the oxygen level in the blood. A low reading may show that the lungs need more support.
• Blood Tests: Check for signs of infection and help assess the person’s overall condition.
• Mucus or Viral Tests: A sample of coughed-up mucus, or a swab from the nose or throat, may help identify the germ, and the result could guide treatment.
• Further Tests: Severe symptoms or an unclear diagnosis may require a more detailed chest scan, blood cultures or other tests.

The results help the doctor decide whether treatment at home is suitable or hospital care is needed.

Pneumonia Treatment Options and Breathing Support

Pneumonia treatment in adults may involve medicines and rest at home. More serious illness may require hospital care.

The treatment depends on the likely cause, the severity of the infection and the patient’s overall health:

• Antibiotics: If bacteria are causing the pneumonia, the doctor may prescribe antibiotics and explain how long to take them. Antibiotics do not work against viruses.
• Antiviral Medicines: Viral pneumonia treatment may include an antiviral medicine suitable for the virus involved. Not every viral infection has a specific antiviral treatment.
• Antifungal Medicines: These may be prescribed when pneumonia is caused by a fungus.
• Rest and Symptom Relief: Rest gives the body time to recover. The doctor may also recommend fluids and medication for fever or pain.
• Hospital Treatment: Patients with severe pneumonia may need close monitoring, fluids or medicines given through a vein.
• Oxygen and Breathing Support: If pneumonia lowers the oxygen level in the blood, extra oxygen may be given through a small tube in the nose or a face mask. If the person still cannot breathe well enough, a ventilator may be needed to help move air into and out of the lungs.

The treatment plan may change if test results become available or the person’s condition changes.

Benefits of Early Pneumonia Treatment

Pneumonia may become more severe if treatment is delayed. An early assessment helps the doctor recognise when more support is needed.

It may:

• Allow suitable treatment to begin before symptoms become more severe
• Identify a low blood oxygen level that needs attention
• Help patients and families recognise which changes require urgent care
• Reduce delays in hospital treatment when care at home is not enough

Complications if Left Untreated

If pneumonia becomes more severe, swelling and fluid in the lungs may increase, leaving the person more breathless.

Serious complications are more likely when severe illness goes untreated, but they can sometimes occur despite treatment:

• Low Blood Oxygen Level: The infected air sacs may struggle to move enough oxygen into the blood.
• Fluid Around the Lung: Fluid may collect between the lung and chest wall. If it becomes infected, it may need to be drained.
• Lung Abscess: A pocket of pus may form within the lung.
• Sepsis: The body’s response to an infection can become harmful and affect other organs.
• Respiratory Failure: The lungs may be unable to provide enough oxygen for the body without urgent breathing support.

When Should You See a Doctor?

Arrange a medical assessment if you have a cough with fever, chest pain or breathlessness, especially if symptoms are worsening. Seek advice promptly if you are older, have a long-term illness or have a weakened immune system. A pulmonologist for pneumonia treatment may be needed if symptoms are severe, keep returning or do not improve as expected.

Seek emergency care immediately if someone has:

• Severe difficulty breathing or cannot speak comfortably because of breathlessness
• Blue or grey lips or skin
• Shows sudden signs of confusion, keeps fainting or has difficulty staying awake
• Severe chest pain that does not settle

Prevention & Lifestyle Modifications

Not every case of pneumonia can be prevented.

However, pneumonia prevention measures can lower the risk of some infections and help protect lung health:

• Ask About Recommended Vaccines: Vaccines against flu and pneumococcal infection can help prevent some types of pneumonia.
• Wash Your Hands Regularly: This helps reduce the spread of germs.
• Avoid Smoking and Second-Hand Smoke: Smoke weakens the lungs’ normal defences.
• Cover Coughs and Sneezes: Use a tissue or your elbow, then clean your hands.
• Get Help with Swallowing Problems: Tell a doctor if food or drink often makes you cough or choke. Managing this problem may lower the risk of food or drink entering the lungs.

Pre-Post Treatment Care

Pre-Treatment

• Note when symptoms started and how they have changed.
• Share any existing lung or heart conditions with your doctor and previous episodes of pneumonia.
• Provide a list of current medicines and mention any medicine allergies.
• Complete recommended tests to check the infection and breathing.
• Ask which symptoms would mean you need urgent reassessment.

Post-Treatment

• Take medications prescribed for pneumonia recovery as directed. Do not stop antibiotics early unless the prescriber changes the plan.
• Rest and drink fluids as advised.
• Return to work, exercise and other activities gradually as your strength improves.
• Attend follow-up appointments if recommended, particularly if symptoms persist.

Seek reassessment if fever returns, breathing worsens or improvement stops.
