IBD nursing team and advice line
The IBD nursing team should be your first point of contact if you require any advice regarding your disease. In particular they can provide support, advice and information on your inflammatory bowel condition. we encourage you to leave a message if you have any query relating to your disease, and especially if you are becoming unwell. 

The IBD Nursing team are also available for booked clinic appointments in the out-patient department, which can be particularly helpful to those who have had a recent diagnosis of IBD.

The Psychological Medicine Unit
The Psychological Medicine Unit is ideally placed to offer psychological assessment and support to patients with gastrointestinal conditions. Following an initial assessment, you may be offered on-going therapy within the unit or locally (closer to home). It can sometimes be difficult to cope with aspects of living with a long-term condition or illness, and psychological support can be made available. If you feel that this service would be of benefit, please discuss a referral with your doctor or GP.

Our surgeons are highly experienced in performing operations using keyhole surgery techniques and have developed an Enhanced Recovery Programme. In addition to this, they also perform open surgery when appropriate.

We understand that contemplating surgery can be a daunting time. When surgery is first discussed you will be advised to have a consultation with one of our highly experienced surgeons.
