Dr Aneez D.B. Ahmed, Senior Consultant Thoracic Surgeon and Medical Director at the International Centre for Thoracic Surgery, a member of Beyond Medical Group, was featured in Shin Min Daily on 15 July 2026, sharing when breathlessness may require medical attention.

Breathlessness refers to difficulty breathing or the sensation of being unable to take in enough air. Although it may occur after strenuous activity, breathing that feels different from usual should not be ignored.

Signs to Look Out For

A person experiencing breathlessness may notice:

• Becoming short of breath more easily than before
• Breathing faster or with greater effort during simple activities
• Tightness or discomfort in the chest while breathing

According to Dr Aneez, it is important to recognise changes from your usual breathing pattern. For example, medical attention may be needed when activities such as walking at a normal pace, climbing a short flight of stairs or speaking for an extended period begin to cause unusual breathing difficulty.

Breathlessness that persists or gradually worsens should also be assessed by a doctor, particularly when accompanied by fatigue, chest discomfort or a reduced ability to carry out daily activities.

A persistent morning cough, wheezing or becoming breathless more easily may sometimes be dismissed as a minor problem. However, when these symptoms continue for several months or gradually worsen, they may be warning signs of an underlying lung condition such as chronic obstructive pulmonary disease.

In a recent feature published in Lianhe Zaobao Fukan on 16 June 2026, Dr Aneez D.B. Ahmed, Senior Consultant Thoracic Surgeon and Medical Director at the International Centre for Thoracic Surgery, discussed the symptoms, risk factors and management of chronic obstructive pulmonary disease, commonly known as COPD.

What Is Chronic Obstructive Pulmonary Disease?

COPD refers to a group of progressive lung conditions that cause ongoing inflammation and obstruction of the airways. The two most common conditions associated with COPD are emphysema and chronic bronchitis.

As the airways become narrower and lung tissue becomes damaged, it becomes increasingly difficult for air to move in and out of the lungs. Over time, patients may experience worsening breathlessness, reduced stamina and difficulty carrying out everyday activities.

The early symptoms of COPD can be mild and easily overlooked. Some people may assume that an occasional cough or wheezing is simply caused by poor air quality, tiredness or smoking. However, persistent symptoms should not be ignored, particularly when they begin to affect daily activities.

Without appropriate management, lung damage may continue and increase the risk of complications such as recurrent respiratory infections and additional strain on the heart and lungs.

Warning Signs to Look Out For

Common symptoms associated with COPD may include:

• Breathlessness, particularly during physical activity
• A persistent or chronic cough
• Wheezing
• Chest tightness
• Frequent respiratory infections
• Ongoing fatigue
• Unexplained weight loss
• Loss of muscle strength

These symptoms may not be obvious during the early stages of the condition. In some cases, they only become noticeable after the lungs have already sustained a significant degree of damage.

Medical attention should be considered when respiratory symptoms persist, become more frequent or gradually worsen.

What Can Cause COPD?

Smoking

Smoking is one of the main risk factors for COPD. Cigarette smoke travels through the airways and exposes the lungs to substances that can irritate and damage the delicate structures responsible for breathing.

Long-term exposure may cause the airways to become inflamed and narrowed, while also affecting the lungs’ ability to exchange oxygen and carbon dioxide.

Smoking may contribute to two common changes in the lungs:

Emphysema occurs when the air sacs in the lungs become damaged and lose their elasticity. This affects the lungs’ ability to absorb oxygen and remove carbon dioxide.

Chronic bronchitis involves persistent inflammation and narrowing of the bronchial tubes, which may lead to long-term coughing, mucus production and airflow obstruction.

Electronic Cigarettes

Electronic cigarettes or vapes, which are banned in Singapore, are sometimes perceived as a safer alternative to conventional cigarettes. However, the vapour or aerosol inhaled may still contain substances that irritate or damage the lungs.

Vaping should therefore not be regarded as harmless, particularly for individuals who already have respiratory symptoms or existing lung disease.

Air Pollution and Workplace Exposure

Long-term exposure to polluted air may also contribute to lung damage. Possible sources include traffic exhaust, smoke, second-hand smoke and dust or chemical irritants in certain working environments.

People who are regularly exposed to these irritants should pay attention to any persistent changes in their breathing.

Recurrent Respiratory Infections

For individuals whose lungs are already damaged, repeated episodes of pneumonia, bronchitis or other respiratory infections may further affect lung function.

These infections can aggravate coughing, breathlessness and airway obstruction, potentially contributing to the progression of COPD.

Protecting Your Lungs Through Early Assessment

Individuals who experience long-term breathing difficulties or have risk factors for COPD should consider seeking medical assessment. Depending on the symptoms and medical history, the doctor may recommend lung function tests, imaging or other investigations.

Treatment is usually tailored to the severity of the condition. Some patients may require inhaled or oral medications to help open the airways, reduce symptoms and improve breathing.

In selected patients with severe or advanced emphysema, surgery may be considered to remove areas of severely damaged lung tissue. A specialist assessment is needed to determine whether such treatment is appropriate.

Although lung damage caused by COPD is often irreversible, early detection and management may help control symptoms and slow further deterioration.

For individuals who smoke, stopping smoking is one of the most important steps in protecting lung health. Reducing exposure to polluted environments, remaining physically active and attending appropriate medical follow-ups may also support better respiratory health.

A cough that lasts for several months or breathlessness that gradually worsens should not simply be accepted as part of daily life. Paying attention to these changes and seeking assessment early may help protect both breathing and overall health.

Dr Aneez D.B. Ahmed, Senior Consultant Thoracic Surgeon and Medical Director at the International Centre for Thoracic Surgery, was invited to Oli 96.8 FM on 10 June 2026 to talk about lung health, chronic cough, smoking, and lung cancer.

Why the Lungs Deserve More Attention

The conversation covered how the lungs and the heart work as a single functional unit, a "compound organ," as it was described. The heart's job is to pump blood, while the lungs act as the filter, oxygenating that blood before it circulates through the body. Because the two organs are so closely linked, the discussion made the point that lung health shouldn't be treated as separate or secondary to heart health. Problems in one system quickly affect the other.

When Should You Worry About a Cough?

One of the key questions raised was: does a cough or breathlessness automatically mean something is wrong with your lungs?

Dr. Aneez shared that an occasional cold can bring on a cough or some breathlessness, and that alone isn't cause for alarm. The real warning sign is duration. If a cough persists for a month or two without improving, that's when it needs proper medical attention. A cough that lingers that long is the body signaling that something isn't resolving on its own, and ignoring it for too long can allow an underlying issue to progress further before it's caught.

The Benefits of Quitting Smoking

Dr. Aneez shared that the lungs have a real capacity to recover after a person quits smoking, with meaningful improvement typically seen within about two years of quitting. This came across as an encouraging point for smokers considering quitting. The damage isn't necessarily permanent, and the body does work to repair itself once the harmful exposure stops.

Can Lung Cancer Be Fully Cured?

Early detection significantly improves the chances of successful treatment. Lung cancer is classified using a staging system, Stage 1 through Stage 4, and outcomes are strongly tied to which stage the cancer is caught at. The earlier the stage, the better the prognosis.

The landscape for lung cancer treatment in Singapore has also changed considerably over the years. Advances in detection and treatment options mean that outcomes today look different from what they were in the past, offering more hope to patients than in previous decades.

Takeaway

Don't ignore a lingering cough, understand that lung and heart health are deeply connected, and know that early detection dramatically improves outcomes for serious conditions like lung cancer. Quitting smoking, meanwhile, remains one of the most effective steps someone can take to protect long-term lung function.

This article is based on the Oli 96.8 FM show, aired on 10 June 2026, featuring Dr. Aneez Ahmed.

Feeling breathless more easily is often brushed aside as part of ageing, stress, or declining fitness. However, as highlighted by Dr Aneez D.B. Ahmed in a recent CNA Lifestyle feature, persistent breathlessness may sometimes point towards underlying chest or lung conditions that deserve proper medical attention.

Here are 5 key takeaways from the feature.

---

1. Breathlessness Should Not Always Be Dismissed As “Just Ageing”

Many individuals assume becoming breathless more easily is simply part of getting older. However, a noticeable change in your ability to carry out routine activities should not be ignored.

If climbing stairs, walking short distances, or speaking for longer periods suddenly feels more tiring than before, it may reflect an underlying issue rather than normal ageing alone.

---

2. People Often Adapt To Symptoms Without Realising

One reason conditions are sometimes detected late is because people subconsciously change their lifestyle to cope with symptoms.

Walking slower, avoiding physical activity, or taking more frequent breaks may gradually become part of daily life. Over time, this can make persistent breathlessness seem “normal”, even when it is not.

Recognising these subtle changes early may help prompt further evaluation before symptoms progress further.

---

3. Not All Chest Symptoms Come Directly From The Lungs

Dr Aneez highlights that some conditions affecting the chest may not originate from the lungs themselves.

For example, the thymus is a small gland located between the lungs, behind the breastbone. Although it is not part of the lungs, conditions involving the thymus may still cause symptoms such as chest discomfort, breathlessness, muscle weakness, or swallowing difficulties because of its location within the chest.

---

4. Routine Tests May Not Detect Every Chest Condition

Routine investigations such as breathing tests and chest X rays remain important, but they may not always detect every condition, especially in earlier stages.

Breathing tests primarily assess lung function, while standard imaging may not fully evaluate all chest structures. When symptoms persist despite “normal” findings, further imaging or specialist assessment may sometimes be required to better understand the cause.

---

5. Persistent Symptoms Deserve Proper Evaluation

Persistent fatigue, chest tightness, chronic cough, or unexplained breathlessness should not simply be ignored or repeatedly self managed without understanding the underlying cause.

Seeking medical advice is not about assuming the worst. It is about making informed decisions and understanding what your body may be trying to tell you.

As emphasised in the CNA feature, early evaluation may allow for more timely assessment and appropriate management if needed.

Breathlessness Causes And When To See A Doctor – CNA Lifestyle

“Pneumonia is often misunderstood as an elderly disease, but anyone can get it — even healthy, young adults.” – Dr Aneez D.B. Ahmed

Pneumonia is an infection of the lungs that causes the air sacs to fill with fluid or pus. It can range from mild to life-threatening, depending on the severity of the infection, the type of pneumonia, and a person’s overall health.

---

Early Cases Highlight the Danger of Pneumonia (0:03–0:17)

Pneumonia can affect people of all ages. Some high-profile cases include:

• February 2015: Singapore’s founding Prime Minister, Mr Lee Kuan Yew, was admitted with pneumonia and passed away the following month.
  
• April 2025: Actor Val Kilmer died from pneumonia.
  

“These cases show that pneumonia is serious and should never be underestimated,” notes Dr Aneez.

---

What Is Pneumonia? (0:49–1:30)

Pneumonia occurs when the lungs’ air sacs become inflamed and filled with fluid. If bacteria, viruses, or other pathogens infect this fluid, it becomes pus, making the condition severe.

• Inflammation alone is not pneumonia; infection must be present.
  
• Left untreated, pneumonia can be life-threatening.
  

---

Who Can Get Pneumonia? (2:36–3:22)

Pneumonia can happen to anyone, but risks are higher at the extremes of age or when underlying conditions exist.

• High-risk groups: very young, seniors, people with chronic conditions, immunocompromised individuals, smokers, vapers, and long-term care residents.
  
• Middle-aged adults without health issues can also develop pneumonia, especially if exposed to infections while travelling or under stress.
  

---

Symptoms: How Pneumonia Differs from Flu (3:22–4:43)

Pneumonia can present like the flu:

Symptom	Bacterial Pneumonia	Viral Pneumonia
Cough	Phlegm, often yellow	Dry
Fever	High	High
Body aches	Mild	Headaches/body aches
Shortness of breath	Common	Less common

“All pneumonias must be treated with equal seriousness — don’t assume viral is mild.” – Dr Aneez

---

Diagnosis (5:23–6:38)

Doctors may use:

• Blood tests for infection markers
  
• Cultures to identify bacteria
  
• Chest X-rays or low-dose CT scans to view lungs
  
• Bronchoscopy in severe cases to remove fluid and test for infection
  
• Home monitoring with a pulse oximeter can help detect early oxygen drops
  

---

Types of Pneumonia (6:41–7:08)

• Bacterial pneumonia – often treatable with antibiotics
  
• Viral pneumonia – may be self-limiting but requires monitoring
  
• Other types – tuberculosis-related pneumonia
  

“Viral pneumonia can still be serious and may require active intervention.” – Dr Aneez

---

Real-Life Experience: Jarrett’s Story (8:08–11:51)

Jarrett, 42, a fit and active adult, contracted bacterial pneumonia during a holiday.

• Symptoms: fever, severe cough, tight chest
  
• Oxygen dropped below 80% → emergency hospitalisation and ICU stay
  
• Recovery involved home oxygen and medications for a month, with careful monitoring and lifestyle adjustments
  
• Even fit individuals must take pneumonia seriously
  

“You always need to be proactive about health — tracking oxygen, blood tests, and exercise helps reduce risk.” – Jarrett

---

Recurrence and Recovery (12:00–15:06)

• Pneumonia can recur, especially in immunocompromised individuals or those with prior lung damage.
  
• Recovery duration depends on severity and fitness:
  
  • Fit adults: 3–6 weeks
    
  • Less fit adults: weeks to months, sometimes up to 6 months
    
• Recurrent infections can cause deconditioning, requiring rehabilitation for diet, exercise, and lung function
  

---

Smoking, Vaping, and Pneumonia Risk (16:02–19:12)

• Vaping reduces lung immunity and increases susceptibility to pneumonia.
  
• Teens and young adults are particularly at risk due to easy access and underestimation of harm.
  
• Smoking and vaping create long-term risks that may only show up years later.
  

“Vaping compromises your lungs’ defenses, inviting infection.” – Dr Aneez

---

Prevention Tips (20:04–20:47)

• Don’t smoke or vape
  
• Exercise regularly (aerobic + resistance training for those 50+)
  
• Maintain a healthy diet
  
• Take flu vaccines and pneumococcal vaccines as recommended
  
• Travel safely with hygiene measures (hand washing, masks, monitoring oxygen)
  

---

Key Takeaways

• Pneumonia can affect anyone, not just seniors.
  
• Early symptoms can mimic flu, but untreated pneumonia can be severe.
  
• Both bacterial and viral types require careful management.
  
• Fitness and proactive health monitoring improve recovery and reduce risk.
  
• Preventive measures like vaccination, avoiding smoking/vaping, and maintaining immunity are crucial.
