Excess weight affects more than appearance. It is closely linked to conditions such as type 2 diabetes, high blood pressure and chronic kidney disease, making effective weight management an important part of improving long-term health. Despite their best efforts, many people find that persistent hunger, weight regain and underlying medical conditions make it difficult to achieve lasting results through lifestyle changes alone.
For some individuals, weight loss medication may provide additional support. Depending on your health, medical history and treatment goals, your doctor may recommend medication as part of a personalised weight management plan alongside dietary changes, physical activity and other lifestyle modifications.
If you have been struggling with persistent weight gain despite ongoing lifestyle changes, Dr Alvin Ng can assess your health and discuss whether weight loss medication may be suitable as part of a personalised weight management plan.
What Is Weight Loss Medication?
Weight loss medications are prescription treatments that may be used to support weight loss in suitable individuals with obesity or excess weight accompanied by weight-related medical conditions.
They are prescribed as part of an individualised weight management plan and are generally used alongside healthy eating, regular physical activity and other lifestyle changes.
How Do Weight Loss Medications Work?
Different weight loss medications work in different ways. Depending on the treatment prescribed, they may help regulate appetite, reduce hunger or increase feelings of fullness, making it easier for some individuals to manage their calorie intake.
Your doctor will consider your medical history, existing health conditions and treatment goals when determining whether medication may be appropriate.
What Are the Potential Benefits of Weight Loss Medication?
Weight loss medication may provide additional support for suitable individuals who have found it difficult to achieve or maintain weight loss through lifestyle changes alone.
Supports Weight Loss
Certain medications can help address physiological factors such as hunger and appetite that may make weight loss more difficult.
Complements Lifestyle Changes
Weight loss medication is generally used alongside healthy eating, physical activity and other sustainable lifestyle modifications.
May Support Metabolic Health
Weight loss may help improve the management of weight-related conditions such as type 2 diabetes and high blood pressure.
Why Kidney Health Matters in Weight Management
Excess weight affects more than body size. It is closely linked to conditions such as type 2 diabetes and high blood pressure, both of which are leading causes of chronic kidney disease (CKD), including diabetic kidney disease (DKD). Addressing excess weight as part of a medically supervised treatment plan may help improve the management of these interconnected conditions and support your long-term health.
As a nephrologist, Dr Alvin Ng approaches weight management with a broader medical perspective. Rather than focusing solely on weight loss, he considers how your weight, kidney function and metabolic health influence one another before recommending the most appropriate treatment plan.
Excess Weight Can Affect Kidney Health
Obesity, type 2 diabetes and hypertension can increase the risk of developing or worsening CKD. Managing weight alongside these related conditions may help reduce their long-term impact on the kidneys as part of comprehensive medical care.
Kidney Function May Influence Treatment Decisions
Kidney function, existing medical conditions and current medications may influence which weight loss medications are suitable for you. Before recommending medication, Dr Ng reviews these factors to determine an appropriate approach based on your individual health needs.
Who May Be Suitable for Weight Loss Medication?
Medical weight loss treatment may be considered for adults who require additional support with weight management.
You may be suitable for assessment if you:
Have obesity or are overweight with one or more weight-related medical conditions.
Have found it difficult to achieve or maintain weight loss through diet and exercise alone.
Are prepared to make long-term lifestyle changes alongside treatment.
Have weight-related metabolic conditions that may benefit from closer medical management.
What to Expect During Treatment
Medical weight loss treatment begins with a comprehensive assessment of your health, weight management goals and suitability for medication. If medication is appropriate, your doctor will recommend suitable options and monitor your progress through regular follow-up appointments, making adjustments where necessary.
Initial Consultation
Your doctor will assess your weight, BMI, medical history, kidney function, current medications and underlying health conditions.
Starting Treatment
If medication is appropriate, your doctor will discuss suitable options based on your health needs and treatment goals.
Starting Treatment
Your doctor will explain how to use the prescribed medication, including the appropriate dose and administration schedule.
Follow-Up Appointments
Regular reviews help monitor your progress, treatment response and any side effects.
Ongoing Monitoring
Your doctor may monitor your kidney function, blood glucose and other relevant health markers throughout treatment.
What Are the Possible Side Effects of Weight Loss Medication?
Different weight loss medications can have different side effects. Your doctor should explain the potential side effects associated with the medication prescribed and what to look out for during treatment.
If you experience persistent or concerning symptoms, contact your doctor for advice rather than changing or stopping your medication without medical guidance.
Practical Tips During Medical Weight Loss Treatment
The following practical tips may help you use your weight loss medication safely and support your treatment throughout the course of therapy.
Follow your prescribed dosing schedule
Use your medication exactly as directed and do not change your dose without medical advice.
Maintain healthy lifestyle habits
Weight loss medication should complement healthy eating, regular physical activity and sustainable lifestyle changes.
Stay well hydrated
Drinking enough fluids is particularly important if you experience nausea, vomiting or diarrhoea, especially if you have underlying kidney disease.
Attend regular follow-up appointments
Regular reviews allow your doctor to monitor your response to treatment, address any concerns and adjust your management plan where appropriate.
