Most people with IIH are overweight. We think losing weight is the best treatment. The IIH Weight trial is trying to find out if weight loss surgery and diet can help treat IIH.
Why am I being asked to take part?
You are being asked to take part because your doctor has diagnosed you with IIH and you are fit enough to be able to have surgery.
Do I have to take part?
No. Taking part is your choice. No one will think badly of you if you don’t take part. You can withdraw at any time if you choose to take part.
What are the possible risks?
If you join the trial you will have a lumbar puncture at 4 or 5 of the visits. There is a risk of headache after a lumbar puncture.
You have a 50:50 chance of being referred for weight loss surgery. This involves general anaesthetic (being put to sleep). All surgery involves some risk, and complications can be serious. However, weight loss surgery is generally very safe and you can discuss the safety of different operations with your surgeon.
Will I be paid for taking part?
In this trial there are two groups of patients. One group is referred to a year of free Weight Watchers. The other is referred to weight loss surgery.
People are put in one these groups at random – like tossing a coin.
