What are the symptoms of ulcerative colitis?

The main symptoms are recurring diarrhoea that may contain blood or mucus, a frequent and urgent need to empty the bowels, abdominal pain and cramping, and tiredness. Some people also experience weight loss, and inflammation elsewhere such as in the joints, skin, or eyes. Symptoms come and go, with flare-ups followed by periods of remission. A change from your usual baseline — more stools, more blood, more urgency — is an important signal to your medical team.

When is an ulcerative colitis flare an emergency?

Seek urgent medical care if you are passing many bloody stools a day, have a fever, a rapid heart rate, severe abdominal pain, or feel very unwell. These can indicate a severe flare that may need hospital treatment. Recognising these warning signs in advance helps you act quickly rather than waiting for a routine appointment, which can prevent complications and get the flare under control faster.

Do people with ulcerative colitis need regular colonoscopies?

Yes. People who have had ulcerative colitis for several years, particularly with extensive disease, have an increased risk of bowel cancer and are offered periodic surveillance colonoscopies to check for early changes. The timing depends on how much of the colon is affected and how long you have had the condition. Your gastroenterologist will advise on the right interval, which is an important part of long-term care.

Can ulcerative colitis be cured?

Ulcerative colitis is a lifelong condition, but it can be well controlled, and unlike Crohn's disease it only affects the large bowel — which means surgery to remove the colon can, in some cases, be curative for the colitis itself. Most people are managed with medication to induce and maintain remission, including aminosalicylates, steroids for flares, immunosuppressants, and biologics. With good management, many people have long periods of remission and a good quality of life.

Preparing for Appointments with Ulcerative Colitis

Quick answer: Track your bowel symptoms — number of stools per day, urgency, blood or mucus — plus abdominal pain, fatigue, and any joint, skin, or eye problems. Bring this diary and your complete medication list. Ulcerative colitis flares and settles, and knowing your baseline versus a flare helps your team treat it quickly. Report increasing blood or many stools a day promptly, as a severe flare needs urgent care.

Ulcerative colitis is an inflammatory bowel disease affecting the large intestine. Because treatment decisions hinge on how active the inflammation is, a precise record of your bowel pattern — especially any change from your usual baseline — is the most valuable thing you can bring.

What to Track Before Your Appointment

Stool frequency and urgency: how many per day, and how it compares to your normal
Blood and mucus: amount and how often
Other symptoms: abdominal pain, fatigue, weight loss, joint/skin/eye problems
Medications: including whether you have missed any. A appointment notebook or IBD app helps you capture this.

Recognising a Severe Flare

Seek urgent medical care if you have many bloody stools a day, fever, a fast heart rate, severe abdominal pain, or feel very unwell — a severe ulcerative colitis flare can need hospital treatment. Knowing this in advance helps you act quickly rather than waiting.

What the Appointment May Involve

Blood and stool tests: inflammation markers (CRP), full blood count, faecal calprotectin
Endoscopy (colonoscopy/sigmoidoscopy): to assess inflammation and extent
Medication review: aminosalicylates, steroids for flares, immunosuppressants, and biologics
Cancer surveillance: long-standing colitis needs periodic colonoscopy monitoring
