About Our Clinic
The purpose of the clinic is to provide access to a doctor-led, virtual, medical weight loss service. All patients will be offered a review by a doctor on a monthly basis, along with weight loss, diet and exercise advice and access to an online doctor.
If needed, indicated and wanted, using a shared management plan, patients can be prescribed weight loss medication. Patients are only offered evidence-based treatments under the supervision of a doctor, with appropriate advice and safety netting.
Patients are assessed and a shared management plan for weight loss is made. Patients have unlimited touch points with help from a clinician available when needed. Being a virtual clinic, the mode of communication is led by the patient and what suits their individual needs.
Patients are given full advice during consultations and provided with written information. They can choose to stop the treatment at any point. Patients will be assessed at all stages as suitable to start or continue the programme.
Our Commitments
🌐 If English is not your first language — we have medical translators into all languages available to help with the consultation. Contact us for more details.
- 1
Encourage equality, diversity and inclusion throughout the clinic.
- 2
Create a working environment and an environment for receiving treatment which is free of bullying, harassment, victimisation and unlawful discrimination, promoting dignity and respect for all, and where individual differences and the contributions of all are recognised and valued.
- 3
Take seriously complaints of bullying, harassment, victimisation and unlawful discrimination by patients, fellow employees, customers, suppliers, visitors, the public and any others in the course of the organisation's work activities. Such acts will be dealt with as misconduct under the organisation's grievance and/or disciplinary procedures, and appropriate action will be taken. Particularly serious complaints could amount to gross misconduct and lead to dismissal without notice. Further, sexual harassment may amount to both an employment rights matter and a criminal matter, such as in sexual assault allegations. In addition, harassment under the Protection from Harassment Act 1997 is a criminal offence.
- 4
Make opportunities for training, development and progress available to all staff, who will be helped and encouraged to develop their full potential, so their talents and resources can be fully utilised to maximise the efficiency of the organisation.
- 5
Make decisions concerning clinical care on sound scientific evidence and experience.
- 6
Review employment practices and procedures when necessary to ensure fairness, and also update them and the policy to take account of changes in the law.
- 7
Monitor the make-up of the workforce regarding information such as age, sex, ethnic background, sexual orientation, religion or belief, and disability in encouraging equality, diversity and inclusion, and in meeting the aims and commitments set out in the equality, diversity and inclusion policy. Monitoring will also include assessing how the equality, diversity and inclusion policy, and any supporting action plan, are working in practice, reviewing them annually, and considering and taking action to address any issues.
