Pneumonia in older adults: Doctor explains why people above 65 face a higher risk of complications and shares symptoms families should watch for | Health

Pneumonia in seniors may occur without a high fever or prominent cough. (Pexels) Why are adults above 65 more vulnerable to pneumonia? Doctor explains seven risk factors, warning signs, life-threatening complications and prevention tipsEvery year, World Pneumonia Day, observed on November 12, reminds us of the importance of understanding pneumonia, recognising its early symptoms and taking steps to prevent it. While pneumonia can affect people of all age groups, older adults, especially those above 65, are more vulnerable to the infection and its complications.

In an interview with HT Lifestyle, Dr Loveleen Mangla, senior consultant and chief interventional pulmonologist, Metro Hospital, Faridabad, with more than 17 years of experience, explains, “As we age, our body's natural defence mechanisms gradually weaken, making it more difficult to fight infections. Older adults are particularly vulnerable to pneumonia because of changes in lung function, reduced immunity and the presence of underlying health conditions.” (Also read: Recurring abdominal pain is not always a digestive problem: Gastroenterologist explains why identifying the underlying cause is crucial )

1. Weakened immune system: Ageing reduces the body’s ability to fight infections, making older adults more vulnerable to pneumonia.

2. Age-related lung changes: Reduced lung elasticity and weaker respiratory muscles affect the lungs’ ability to clear mucus effectively.

3. Impaired cough reflex: A weaker cough makes it difficult to remove mucus and harmful microorganisms from the respiratory tract.

4. Swallowing difficulties: Food, liquids, or saliva may accidentally enter the lungs, leading to aspiration pneumonia.

5. Chronic medical conditions: Diabetes, COPD, asthma, heart disease, kidney disease and neurological disorders increase the risk of infection and complications.

6. Poor nutrition: Malnutrition and frailty can weaken immunity and delay recovery.

7. Reduced mobility: Prolonged bed rest and limited physical activity can affect lung expansion and airway clearance.

Dr Mangla explains, “Pneumonia can become particularly dangerous in older adults because their bodies may have limited reserves to cope with the infection. When inflammation affects the air sacs of the lungs, oxygen levels can fall significantly. In severe cases, the infection may lead to respiratory failure, sepsis and dysfunction of other vital organs.”

Importantly, pneumonia may not always present with typical symptoms in older adults.

“Older adults may develop pneumonia without a high fever or prominent cough. Sometimes, sudden confusion, unexplained falls, loss of appetite, excessive weakness or a sudden decline in their general health may be the earliest indications of an underlying infection. Families and caregivers should remain alert to such changes and seek timely medical evaluation,” says Dr Mangla.

1. Stay up to date with vaccinations: Take pneumococcal and annual influenza vaccinations as recommended by a healthcare professional.

2. Stay physically active: Regular, age-appropriate exercise supports lung function and overall health.

3. Maintain good nutrition: A balanced diet with adequate protein, vitamins and minerals helps support immunity.

4. Stay hydrated: Drink sufficient fluids unless medically restricted.

5. Practise good oral hygiene: Regular brushing and dental care help reduce harmful microorganisms.

6. Avoid smoking: Stay away from tobacco and second-hand smoke.

7. Manage chronic conditions: Keep diabetes, COPD, asthma and heart disease under control.

8. Seek timely medical advice: Do not ignore persistent cough, breathing difficulties, fever or sudden confusion.

Dr Mangla concludes, “The key to reducing pneumonia-related complications in older adults is prevention, early recognition and timely medical intervention. Families should not dismiss sudden weakness, confusion or breathing difficulties as a normal part of ageing. Appropriate vaccination, good nutrition, physical activity and proper management of chronic illnesses can go a long way in protecting the respiratory health of senior citizens.”
