Doctor's Duty of Care: Prescribing Weight-Loss Medications Responsibly (2026)

A doctor's duty of care is non-negotiable, and the Malaysian Medical Association (MMA) is here to remind us of that. In a recent statement, the MMA addressed the concerning reports of doctors allegedly leasing their credentials to aesthetic operators, which has led to the improper prescription of weight-loss medications.

The core of the issue: a breach of trust and ethics.

MMA President Datuk Dr. Thirunavukarasu Rajoo emphasized that the duty of care rests solely with the doctor, and any proven instances of such practices would be a severe violation of professional ethics and patient trust.

But here's where it gets controversial...

The Letter of Credentialing and Privileging (LCP) is a critical document that ties a doctor's competence, clinical judgment, and accountability to their practice. Dr. Thirunavukarasu made it clear that when a clinic operates under a doctor's name without genuine supervision or when an LCP is essentially rented out, the responsibility doesn't vanish into thin air. It remains with the doctor, and that's a non-delegable fact.

And this is the part most people miss: the potential medico-legal consequences. These practices not only breach professional ethics but also carry legal risks under existing laws and regulations.

Dr. Thirunavukarasu expressed deep concern over the misuse of semaglutide (Ozempic) and tirzepatide (Mounjaro) as quick-fix cosmetic solutions. Originally developed for diabetes and obesity management, these medications require a proper medical assessment, counselling, and follow-up. Prescribing them without proper oversight could lead to severe gastrointestinal symptoms, dehydration, and other complications for patients, while also limiting access for those who genuinely need these medications.

A stark reminder of the importance of informed consent.

Financial arrangements should never compromise clinical standards, and this applies across the board, whether it's a physical clinic, an aesthetic centre, or even digital telemedicine platforms. Medicine should never become a purely transactional business.

The MMA urges the public to be cautious and verify that their doctors are properly registered and that consultations include a full assessment and counselling. No medical procedure is risk-free, and informed consent is a patient's right.

Dr. Thirunavukarasu concluded by stating that the MMA supports investigations and enforcement by relevant authorities where breaches of professional conduct are identified.

So, what are your thoughts on this matter? Do you think these practices are a breach of trust, or is there a different perspective to consider? Feel free to share your opinions in the comments below!
