You can enter your weight manually into Apple Health and then sync the data to the Allurion app.
To do this, please follow these steps:
1. Open Health app on your iPhone > find Weight > Add Data in top right corner > enter the weight and tap Add
2. Open Settings > scroll to the bottom and tap Apps > Health > Data Access & Devices > Allurion > Turn On All (so that the weight data can be shared between Apple Health and Allurion app)
If you are being followed by a medical provider, please reach out to your clinic and they can enter this weight for you in their platform.
