Getting to the clinic

Aspen Diabetes & Endocrine Clinic is at Novena Medical Center on Sinaran Drive, within the Novena medical cluster. The nearest station is Novena MRT (NS20) on the North–South Line; from the station, sheltered linkways connect to the Square 2 and Novena Medical Center buildings on Sinaran Drive, making the walk short and weather-protected. Several bus services run along Thomson Road and the surrounding roads, and taxi or ride-hailing drop-off is available at the building entrance.

Novena Medical Center has a paid visitor carpark for those driving, shared with the adjacent Square 2 mall, which is convenient for parking and refreshments before or after a visit. The Novena area is busy on weekday mornings, so allow time to find the correct unit and confirm the floor and suite with the clinic when booking.

What diabetes care covers

Dr Yeoh’s focus is diabetes, a condition in which blood sugar is too high because the body does not make or use insulin properly. Her listed interests include type 1 diabetes, where the body makes little or no insulin; hypoglycaemia, meaning low blood sugar, which can complicate treatment; and the use of advanced diabetes technologies such as insulin pumps and continuous glucose sensors. These tools can help fine-tune control and reduce swings in blood sugar.

Her interests also include obesity, which is closely linked to type 2 diabetes, along with thyroid disorders and general endocrinology. Modern diabetes care aims not only to manage blood sugar but to protect the eyes, kidneys, nerves, heart and circulation over the long term, tailoring treatment to each person’s lifestyle and goals.

What to expect at a consultation

A first visit usually begins with a history of your diabetes or symptoms, current treatment, blood-sugar patterns, episodes of high or low readings, diet, activity and any complications. The doctor reviews your medications, including insulin or other therapies, and your general health. Examination typically includes blood pressure, weight, and checks of the feet and other areas at risk in diabetes.

Investigations commonly include HbA1c, which reflects average blood sugar, along with kidney function, lipids and other tests. If you use a glucose sensor or pump, the data may be reviewed. The findings are discussed and a plan agreed, which may involve adjusting medication, considering diabetes technology, or addressing weight and other risk factors.

Preparing for your appointment

• Photo identification and any GP or polyclinic referral letter.
• Previous records and blood results, especially recent HbA1c and kidney tests.
• A current list of medications and supplements, with doses, including insulin.
• Your home blood-glucose readings, or your meter, pump or sensor and its data if you use one.
• A written list of symptoms and questions, including any low blood-sugar episodes.

Some diabetes blood tests are taken fasting, so ask the clinic whether you should avoid food before your visit, and continue your usual medication unless advised otherwise.

After your consultation and follow-up

After the consultation you will receive an explanation of your results and an agreed plan. The clinic will advise how results are shared and when to return. Diabetes is a long-term condition, so regular follow-up helps adjust treatment, review technology settings, and check for complications affecting the eyes, kidneys, nerves and circulation.

You may be referred for eye screening, kidney assessment, dietitian or diabetes nurse input, or other specialist care. Continuity helps keep treatment consistent and avoids duplicate tests. A second opinion can be sought at any time. Seek urgent care for very high blood sugar with vomiting, drowsiness or rapid breathing, or for severe low blood sugar that does not respond to sugar intake.

Booking, referrals and fees

As a private specialist, Dr Yeoh 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 and chronic-disease care within set limits, while consultations and some technology costs are usually out of pocket. Confirm current fees and what is claimable directly with the clinic.

Common questions

What is the difference between type 1 and type 2 diabetes?

In type 1 the body makes little or no insulin and needs insulin treatment; type 2 is linked to insulin resistance and is often related to weight and lifestyle.

What does an insulin pump or glucose sensor do?

These technologies help deliver insulin more precisely and track blood sugar continuously, which can improve control and reduce swings.

Why does low blood sugar matter?

Hypoglycaemia can cause shakiness, confusion or collapse; managing it is an important part of safe diabetes treatment.

How often will I need follow-up?

This varies, but regular reviews help adjust treatment and screen for complications over time.
