TD,

if you've always struggled with your weight, and you are gaining more each year, it's not silly to want to try to stop it now.

Generally speaking, you need to be a BMI of 35 or more without co-morbidities (health issues). But you can still get lapbanding done if your BMI is over 30 if you have a significant family history of obesity-related health issues such as diabetes, heart disease and hypertension.

It won't hurt to speak to your GP and see where you stand.
