Doctor

Located just behind your YazenCoach, the doctors ensure that your prescription is as effective as possible. All doctors at Yazen are experts in the treatment of patients struggling with their weight.

Your doctor assists you with questions about medication treatment, renews prescriptions, wants to know how you experience the effects of the medication, and assesses weight loss and any side effects. In case of side effects that do not improve with adjustments to the diet, such as heartburn, constipation or nausea, medication may be prescribed. You can also receive assistance with certificates, such as Activity on Prescription (AoP) or travel certificates.

Gemma Collins: "I’ve lost 3½ stone and kept it off with Yazen - it feels so good!”

Gemma Collins is ending 2025 3½ stone lighter thanks to Yazen and is now amazed at the different reflection staring back at her in the mirror.

For me, it’s not about looking stick thin as that isn’t who I am. It’s about being as healthy as I can and Yazen helps me keep going in the right direction. I’m being sensible with my weight loss journey and not trying to rush results.
