Treatment Treatment for ulcerative colitis aims to relieve and prevent symptoms. Your treatment will depend on how severe your symptoms are and how often they flare up. Mild flare-ups can be usually be treated at home. But severe flare-ups usually need treatment in hospital to reduce the risk of complications. Treatment will usually be provided by a range of healthcare professionals. Medication Most people will get medication to treat symptoms of ulcerative colitis. This includes medications like: aminosalicylates (ASAs)  often the first treatment option, used to get and keep inflammation under control and can be given rectally as well as orally corticosteroids  used to get inflammation under control quickly, but not suitable for long-term use If you have lots of flare-ups or aminosalicylates do not keep your inflammation under control, you may need other treatments, such as: immunosuppressants like azathioprine or mercaptopurine  used to reduce the activity of the immune system biologic medicines, like adalimumab, infliximab, golimumab, ustekinumab or vedolizumab other advanced medicines like filgotinib, ozanimod, tofacitinib and upadacitinib Surgery Surgery to treat ulcerative colitis may be an option if: you choose to have surgery instead of taking medications that may cause side effects medications dont control your symptoms your quality of life is severely affected by your condition you have serious complications of ulcerative colitis Surgery for ulcerative colitis involves removing part or all of your large bowel (known as a colectomy). This means the small intestine must be used to pass waste products out of your body instead. During the surgery, your small intestine will either be: joined to the surface of your tummy (known as an ileostomy or a colostomy)  after this type of surgery, poo comes out of the opening on your tummy and is collected in special bags that you wear joined directly to your rectum (the end of your large bowel), so your poo comes out of your bottom as usual used to create an internal pouch thats connected to your bottom (known as an ileo-anal pouch or J-pouch)  this means your poo can pass through your bottom as usual Diet Theres no evidence that a particular diet causes ulcerative colitis. But alongside medications, some changes to your diet may help control symptoms for some people. You could: eat 5 to 6 small meals rather than 3 main meals try to eat a healthy, varied diet that includes a wide variety of fruit, vegetables, nuts, seeds, proteins and wholegrains drink plenty of water You could also speak to your IBD team about: keeping a food diary to find out if any particular foods affect your symptoms removing trigger foods from your diet  but do not make major changes to your diet without talking to your IBD team and make sure you are still getting all the nutrients you need taking a food supplement if you are struggling to get enough nutrients from your diet being referred to a dietitian Managing stress Stress doesnt cause ulcerative colitis. But, managing stress may reduce how often you get symptoms. To help manage stress, you could: exercise  speak to your IBD team about a suitable exercise plan try relaxation techniques like yoga, medication and breathing exercises talk to others  Crohns & Colitis UK has details of local support groups speak to your GP if you think you may have depression Fertility and pregnancy A womans chance of becoming pregnant isnt usually affected by ulcerative colitis. However, surgery for ulcerative colitis might affect your fertility, especially pouch surgery. Most women with ulcerative colitis will have a normal pregnancy and a healthy baby. But if youre pregnant or planning a pregnancy you should discuss it with your IBD team. This is because they may need to change your medication. If youre having a flare-up of ulcerative colitis you may also be advised to avoid getting pregnant until its under control. Complications If you have ulcerative colitis, you may be at an increased risk of developing other problems. This can include: osteoporosis poor growth and development in children and young people More serious and rare complications can include: primary sclerosing cholangitis (PSC)  inflammation in the bile ducts, which can lead to liver damage narrowings in the bowel (strictures) that may become blocked or make it difficult for poo to pass through toxic megacolon  severe inflammation in the colon may lead to trapped gas so the colon becomes very enlarged and can rupture a higher risk of getting bowel cancer a higher risk of getting blood clots in your legs or lungs Source: Scottish Government - Opens in new browser window Last updated: 25 January 2024 How can we improve this page?
