Getting to the clinic
Loh Keh Chuan Diabetes Thyroid & Hormone Clinic is located at Mount Elizabeth Medical Centre, in the Orchard area. The nearest station is Orchard MRT (NS22 / TE14), which links the North–South and Thomson–East Coast Lines; from there it is a short walk to the Mount Elizabeth complex on Mount Elizabeth Road, just off Orchard Road. Numerous bus services run along Orchard Road and Paterson Road, and taxi or ride-hailing drop-off is available at the medical centre entrance.
Mount Elizabeth Medical Centre has a paid visitor carpark for those driving, though the Orchard area is busy, particularly on weekday mornings and at weekends. Allow time to find the correct unit within the building, and confirm the floor and suite number with the clinic when you book.
What thyroid medicine covers
Dr Loh’s main interest is the management of thyroid disease. The thyroid is a small gland in the neck that controls metabolism through its hormones. Disorders include an overactive thyroid (hyperthyroidism), an underactive thyroid (hypothyroidism), goitre (an enlarged thyroid), and thyroid nodules, which are lumps that may be benign or, less commonly, cancerous. His listed expertise includes ultrasound-guided biopsy and sclerotherapy of thyroid nodules and the management of thyroid cancer.
An ultrasound-guided biopsy uses a fine needle, directed by ultrasound, to sample a nodule and check whether it is harmless. Sclerotherapy is a technique used to shrink certain benign nodules or cysts. His interests also extend to diabetes and general endocrinology, reflecting the broad scope of hormonal health.
What to expect at a consultation
A first visit usually begins with a history of your symptoms, which might include neck swelling, changes in weight, energy, heart rate, mood, bowel habit or temperature tolerance, along with any family history of thyroid disease. The doctor reviews your medications and general health. Examination typically includes feeling the thyroid in the neck and checking the pulse and other signs of thyroid over- or under-activity.
Investigations commonly include thyroid function blood tests and a thyroid ultrasound to assess the gland and any nodules. If a nodule needs further evaluation, an ultrasound-guided fine-needle biopsy may be arranged. The results are explained and options discussed, ranging from monitoring or medication to procedures, depending on the diagnosis.
Preparing for your appointment
- Photo identification and any GP or polyclinic referral letter.
- Previous records, thyroid blood results and any earlier neck ultrasound or biopsy reports.
- A current list of medications and supplements, with doses, including any thyroid medication.
- A note of when you first noticed neck swelling or other symptoms.
- A written list of symptoms and questions.
If you already take thyroid medication, ask the clinic whether to take it as usual before any blood tests, as timing can affect some results.
After your consultation and follow-up
After your consultation you will receive an explanation of your results and a plan. If a biopsy or other test was arranged, the clinic will advise how and when results are shared and whether a review is needed. Thyroid conditions are often managed over time, so follow-up helps adjust medication and monitor nodules or the gland after treatment.
You may be referred for further imaging, a procedure, or assessment by a surgeon if surgery is being considered. Continuity of care keeps treatment consistent and avoids duplicate scans. A second opinion can be sought at any time. Seek urgent care for sudden difficulty breathing or swallowing from a rapidly enlarging neck swelling, or symptoms of a severe thyroid storm such as a very fast heart rate with fever and agitation.
Booking, referrals and fees
As a private specialist, Dr Loh can generally be seen without a referral, though a GP or polyclinic letter aids continuity and may help with subsidies if you are later directed to a public clinic. MediSave, MediShield Life or an Integrated Shield Plan may apply to eligible procedures, such as certain biopsies, within set limits, while consultations are usually out of pocket. Confirm current fees and what is claimable directly with the clinic.
Common questions
Are thyroid nodules usually cancer?
Most thyroid nodules are benign. A biopsy may be advised to confirm this when a nodule has features that need checking.
What is an ultrasound-guided biopsy?
It uses ultrasound to guide a fine needle into a nodule to take a small sample, helping determine whether it is harmless.
Will I need to take thyroid medication for life?
It depends on the condition. Some thyroid problems need long-term treatment, while others are temporary or resolve after treatment.
What is nodule sclerotherapy?
It is a technique used to shrink certain benign nodules or cysts without surgery, where appropriate.
