Dr Felicia Teo Su Wei is a Senior Consultant in the Division of Respiratory and Critical Care Medicine at the National University Hospital. She obtained her medical degree from the University of Nottingham and is dually accredited in Respiratory Medicine and Intensive Care Medicine.
She trained at the interstitial lung diseases unit at the Royal Brompton Hospital in London, and went on to establish and lead the interstitial lung disease (ILD) service at NUH, including a combined rheumatology-ILD service for connective-tissue-disease-associated ILD.
She is an Assistant Professor at the Yong Loo Lin School of Medicine, NUS. Her special interests include interstitial lung disease, endobronchial ultrasound, pulmonary infections in the immunocompromised, and intensive care.

Getting to the clinic
Dr Felicia Teo Su Wei sees patients within the Division of Respiratory and Critical Care Medicine at the National University Hospital (NUH), on the Kent Ridge campus in the west of Singapore. The most direct way to arrive by public transport is the Circle Line: alight at Kent Ridge MRT (CC24), which connects directly into the hospital complex through a sheltered link, so you can reach the main building without walking in the open. From Kent Ridge station, follow the signs for the hospital and the relevant tower; staff at the information counters can point you to the specialist outpatient clinics.
NUH is also well served by public buses running along the surrounding roads, and the campus shares transport links with the National University of Singapore. If you are coming by taxi or a ride-hailing service, ask to be set down at the main hospital drop-off point, which keeps walking to a minimum for anyone who is breathless or unsteady. As a public hospital, NUH has a multi-storey visitor carpark on site for those who prefer to drive; charges apply and the upper decks tend to be quieter at busier times of day. Allow extra time on your first visit to register, locate the correct clinic and complete any pre-consultation checks.
What interstitial lung disease care covers
Interstitial lung disease (ILD) is an umbrella term for a large group of disorders that scar or inflame the lung tissue between the air sacs. Because this tissue stiffens, the lungs become harder to expand and oxygen passes less easily into the blood, which is why breathlessness on exertion and a persistent dry cough are such common features. Some forms are idiopathic, meaning no cause is found; others are linked to autoimmune and connective-tissue diseases, inhaled dusts or moulds, certain medicines or previous treatments. Dr Teo helped establish and lead the ILD service at NUH, including a combined rheumatology-ILD service for connective-tissue-disease-associated ILD, so assessment for an underlying rheumatological cause is part of how this kind of clinic works.
Care in this field is rarely a single test or a single prescription. It usually means piecing together the breathing history, examination findings, blood tests, lung-function measurements and detailed imaging to reach a confident diagnosis, then matching treatment to the specific subtype. Her listed interests also include endobronchial ultrasound, pulmonary infections in the immunocompromised, and intensive care, reflecting the wider respiratory and critical-care expertise that supports complex lung disease.
What to expect at a consultation
A first appointment generally begins with a thorough history. Expect questions about how long you have been breathless or coughing, what makes symptoms worse, your occupation and hobbies, exposure to dusts, birds or mould, smoking history, current and past medicines, and any joint, skin or other symptoms that might point to an autoimmune condition. The doctor will examine your chest, listen for the characteristic crackles heard in some scarring conditions, and check your oxygen levels and general circulation.
Investigations are often arranged to clarify the picture. These may include blood tests, breathing tests such as spirometry and gas-transfer measurements, and high-resolution imaging of the lungs. Where needed, sampling of the airways or lymph nodes may be discussed. The consultation usually ends with a clear explanation of the working diagnosis, what each test is for, and the options for monitoring or treatment.
Preparing for your appointment
Bringing the right information helps the visit run smoothly:
- Your photo identification and any GP or polyclinic referral letter.
- Previous chest scans, X-rays or CT images and reports, ideally on disc or accessible electronically, along with earlier lung-function results.
- A current list of all medicines and supplements, including doses.
- A written timeline of your symptoms — when the breathlessness or cough began and how it has changed.
- Details of any occupational or hobby exposures, and any autoimmune or joint symptoms.
- A list of questions you want answered.
After your consultation and follow-up
After the visit you will usually receive a plan that sets out the diagnosis or the further tests needed to confirm it. Results from imaging, blood work and breathing tests are reviewed at follow-up, where treatment can be started, adjusted or monitored over time. Interstitial lung disease is often a long-term condition, so regular review of symptoms and lung function helps track stability or change. Referrals may be made for additional tests, pulmonary rehabilitation, vaccination advice or, in selected cases, specialist multidisciplinary discussion. You are entitled to seek a second opinion at any point. Seek urgent medical attention if you develop sudden severe breathlessness, chest pain, coughing up blood, or a rapid worsening that does not settle.
Booking, referrals and fees
As Dr Teo practises within a public hospital, a referral from a GP or polyclinic is commonly used and can help with subsidy eligibility for those who qualify. For eligible procedures and investigations, MediSave, MediShield Life and Integrated Shield Plans may apply within the usual limits, while outpatient consultations are typically paid out of pocket. Always confirm current fees, subsidy status and appointment availability directly with the clinic before you attend.
Common questions
Is interstitial lung disease the same as pulmonary fibrosis?
Pulmonary fibrosis, meaning scarring, is one pattern within the broader interstitial lung disease family. Identifying the exact subtype matters because it guides treatment and outlook.
Why might I be asked about my joints and skin?
Some ILDs are linked to autoimmune and connective-tissue diseases, so questions about joints, skin and other symptoms help check for an underlying cause that may need its own treatment.
Will I need a lung biopsy?
Not always. Many cases are clarified with imaging, blood tests and breathing tests; tissue sampling is only discussed when it would meaningfully change the diagnosis or plan.
How often will I need to be seen?
Because ILD is often long-term, regular reviews are used to monitor lung function and symptoms. The interval depends on your specific condition and how stable it is.
