Ulcerative colitis is a chronic inflammatory bowel disease (IBD), causing inflammation and ulcers in the innermost lining of the large intestine (colon) and rectum. Unlike Crohn’s disease—which can affect any part of the digestive tract and penetrates deeply into tissues.
UC affects only continuous areas of the colon and rectum. Symptoms of ulcerative colitis develop gradually and can be debilitating, sometimes leading to serious complications. While there is no cure, treatments are available to significantly reduce symptoms and may even lead to long-term remission.
These can vary depending on how much of the colon is affected and the level of inflammation.
Symptoms can range from mild to severe, with the condition sometimes being unpredictable. Symptoms are often worse first thing in the morning and they can flare-up and then disappear (known as remission) for months or even years. During a flare-up, the patient is considered to be in the acute phase.
The severity of the condition is judged by the following:
If you are experiencing the symptoms above, you should seek medical advice.
If you are experiencing a severe flare-up of symptoms you may be required to be admitted to hospital as a precaution. A severe flare-up is usually described as passing six or more bloody stools in one day and having symptoms that suggest you are very unwell such as fever, rapid heartbeat and anaemia.
If you have ulcerative colitis, you should note that in all cases, without treatment, symptoms will
eventually return.
The physician will start by asking about your symptoms, health, and medical history, followed by a physical exam focused on the abdomen and rectum. Blood and urine tests will be taken for analysis. If ulcerative colitis is suspected, further tests—such as ultrasound, endoscopy, or radiography—will help determine the disease’s location and severity. A referral to a gastroenterologist may also be recommended. After reviewing all results, the physician can confirm the diagnosis and rule out other possible causes.
There is currently no cure for ulcerative colitis so the aim of treatment is to relieve symptoms during a flare-up and prevent symptoms from returning during remission.
Depending on the severity of the disease, mild to moderate “flare-ups” can usually be treated at home. The most common current treatment is the administration of 5-ASAs or steroids.
In April 2013, a new treatment option product by the name of TRUD™ (medical device- a regulatory classification) has been developed and registered across Europe effective for patients suffering from mild to moderate ulcerative colitis. TRUD™ contains biocompatible and natural components which are also produced by your body system and promotes the healing of ulcers in the colon and rectum.
In some cases, patients might be intolerant to certain medication, and/or have used it and no longer respond to the medication. The latter group are also known as non-responders. TRUD™ might be an effective option for these patients or for patients looking for a non-drug approach to ulcerative colitis.
A severe flare-up needs to be treated in hospital as there is a chance of serious complications. Severe active ulcerative colitis should be managed in hospital to minimise the risk of dehydration, malnutrition and potentially fatal complications such as your colon rupturing. You will be given intravenous (injected directly into your vein) fluid to treat dehydration.
Medications such as aminosalicylates (5-ASAs) and corticosteroids (steroid medications) are most often used but are also dependent on a patient’s response to the medication(s) and severity of the disease.
There is a general treatment scheme which is followed by physicians with increasing severity of treatment:
First line: 5-ASAs (click here for more information)
Second line: Steroids (click here for more information)
Third line: Immunosuppresants (medication that works by suppressing your immune system) (click here for more information)
Fourth line: anti TNF-α (click here for more information)
Fifth line: Surgery (click here for more information)
The choice of treatment is dependent on the patient’s history and severity of the disease (recognised from the symptoms).
If you experience a severe flare-up you may need to be admitted to hospital where you can be given injections of corticosteroids or immunosuppressants.
Once your symptoms are under control it may be recommended that you continue to take certain medication (usually 5-ASA) as these can help prevent further flare-ups; this is known as maintenance therapy.
Once the symptoms are in remission, taking a regular dose of 5-ASA should help prevent symptoms reoccurring. If the condition frequently reoccurs, a regular dose of an immunosuppressant might be recommended.
If your ulcerative colitis flare-up was extensive, a lifelong maintenance therapy is normally recommended.
If your ulcerative colitis flare up was limited to a small part of your colon, you may be able to stop therapy, if two years pass without a return of symptoms.
Aminosalicylates are the first treatment option for mild to moderate ulcerative colitis. They help reduce inflammation and can be taken:
• Orally: as a tablet or capsule that you swallow
• Suppository: a capsule that you insert into your rectum, where it then dissolves
• Enema: where fluid is instilled into your colon
How you take aminosalicylates will depend on the severity and extent of your condition.
The side effects of aminosalicylates can include:
• Diarrhoea
• Feeling sick
• Headaches
• Skin rashes
Corticosteroids (steroid medication) may be used if your ulcerative colitis is more severe or not responding to aminosalicylates. Steroids act much like aminosalicylates. That is, they help by reducing inflammation, except they are a lot stronger.
You may be given immunosuppressants if your condition is still not responding to treatment, sometimes in combination with other medicines although it may also be recommended to withdraw your steroid treatment to reduce possible side effects. This is known as steroid-sparing therapy.
This type of medication is only used to treat severe active ulcerative colitis if you are unable to take steroid medication for medical reasons, such as being allergic to it. There is also a relatively new type of medication called infliximab that can be used to treat severe ulcerative colitis where corticosteroids cannot be used for medical reasons.
Surgery is the most extreme course of treatment and may be recommended when all medications have failed or if “flare-ups” of symptoms are frequent. This involves the removal of a section of the colon.
Ulcerative colitis is not an uncommon condition. The condition normally appears in a person between the ages of 15 and 30.
It is more common in white people of European descent – especially those descended from Ashkenazi Jewish communities – and black people. The condition is much rarer in people of Asian background. The reasons for this are unclear. Both men and women seem to be equally affected by ulcerative colitis
Living with a long-term condition that is as unpredictable and potentially debilitating as ulcerative colitis, particularly if it is severe, can have an emotional impact. In some cases anxiety and stress caused by ulcerative colitis can trigger depression.
You may find it useful to talk to others affected by ulcerative colitis, either face to face or via the internet. A good resource would be your local patient association.
The outlook for most people with ulcerative colitis is usually quite good. Symptoms are often mild to moderate and can be controlled with medication. However, an estimated one-in-five people with ulcerative colitis have severe symptoms that fail to respond to medication. In these cases, it may be necessary to surgically remove the colon.
Although diet does not seem to play a role in causing ulcerative colitis, it can help control the condition.
The following advice may help:
• Keep a food diary: you may find you can tolerate some foods, while others make your symptoms worse. By keeping a record of what and when you eat, you should be able to eliminate problem foods from your diet.
• Eat small meals: eating five or six smaller meals a day, rather than three main meals, may make you feel better.
• Drink plenty of fluids: it is easy to become dehydrated when you have ulcerative colitis, as you can lose a lot of fluid through diarrhoea. Water is the best source of fluids. Avoid caffeine and alcohol as these will make your diarrhoea worse and fizzy drinks as these will cause gas.
• Food supplements: ask your GP or gastroenterologist whether you need food supplements, as you might not be absorbing enough vitamins and minerals, such as calcium and iron.
Although stress does not cause ulcerative colitis, successfully managing stress levels may reduce the frequency of symptoms. The following advice may help:
• Exercise: exercise has been proven to reduce stress and lift your mood. Your GP or gastroenterologist should be able to give advice on a suitable exercise plan.
• Relaxation techniques: breathing exercises, meditation and yoga are good ways of teaching yourself to relax.
• Communication: living with ulcerative colitis can be frustrating and isolating. Talking to others with the condition can be of great benefit
Ulcerative colitis is thought to be what is known as an autoimmune condition. This means the immune system goes wrong in some way and attacks healthy tissue. One theory is the immune system mistakes harmless bacteria inside the colon as a threat and attacks the tissues of the colon, causing it to become inflamed. In severe cases, painful sores which bleed and produce mucus and pus may form. It is likely, that chronically recurring episodes of inflammation in the bowel are related to a complex interaction between various environmental factors and a hereditary predisposition for ulcerative colitis.
Genetic predisposition requires the action of other, still unknown factors in order for an affected individual to actually develop the disease. These factors may include viruses or bacteria, changes in nutritional behaviour or the consumption of certain preservatives or other food additives, as well as disturbances of the body’s own immune defence system. To date, no definitive evidence has been found to prove a connection between these factors and the development of inflammatory bowel disease. It is, however, very probable that environmental factors play a role.
The role of psychological factors remains controversial. While stress may under certain circumstances, provoke an acute flare-up of an existing disease, it is not the underlying cause of inflammatory bowel disease.
The reduced absorption of vitamins and some trace elements (minerals) in patients with ulcerative colitis might result in symptoms such as:
• Night blindness,
• Deafness,
• Changes in taste sensation,
• Vulnerability to infection,
• Hair loss, infertility (in men),
• Growth retardation (in children) and,
• Certain skin changes
Not all patients have experience these physical changes.
For example, a patient might encounter:
• Anaemia due to iron deficiency, loss of blood from the bowel, and/or by vitamin B12 mal-absorption;
• Reduced uptake of bile acids in the small bowel and an increased absorption of bilirubin (bilirubin is the yellow breakdown product of normal heme catabolism. Heme is a principal component of red blood cells) in the colon and have an increased risk of gallbladder stones;
• Increased loss of water which may result in kidney stones;
• Inflammation of the bile ducts (tubes that transport bile out of the liver) – this is known as primary sclerosing cholangitis and can cause symptoms such as itchy skin and tiredness
These can affect a few patients. Serious complications that have been reported are:
Acute ballooning of the bowel due to gases becoming trapped inside the colon (“toxic megacolon”) – affecting approximately 1 in 20 persons with severe ulcerative colitis;
• Perforation, the formation of a hole in the wall of the bowel;
• Extensive haemorrhage;
• Primary sclerosis cholangitis (PSC) – affects 1 in every 20 cases;
• Bowel cancer;
• Osteoporosis – affecting an estimated 1 in 6 people;
Due to these serious complications, peritonitis (inflammation of the membranous lining of the abdomen), and/or intestinal obstruction (medically known as ileus) may occur. These are life-threatening conditions requiring immediate hospital admission and often emergency surgery.
People with ulcerative colitis also have an increased risk of developing bowel cancer. Because of this, regular bowel cancer check-ups are recommended.
Toxic megacolon is a rare and serious complication that occurs in approximately 1 in 20 of cases of severe ulcerative colitis. In severe cases of inflammation, gases can get trapped in the colon, causing it to swell.
PSC is where the bile ducts become progressively inflamed and damaged over time. Bile ducts are small tubes used to transport bile (digestive juice) out of the liver and into the digestive system. PSC does not usually cause symptoms until it is in an advanced stage.
People who have ulcerative colitis have an increased risk of developing bowel cancer (cancer of the colon, rectum or bowel), especially if the condition is severe or extensive.
Osteoporosis is a common complication affecting an estimated 1 in 6 people with ulcerative colitis. Osteoporosis is a condition that affects the bones, causing them to become thin and weak. The condition is not directly caused by ulcerative colitis, but develops as a side effect of prolonged steroid use. Although risks associated with steroid use are well-known, in some people long-term use of steroids is the only way to control symptoms of ulcerative colitis.
