Expert care for chronic colon inflammation
Ulcerative colitis (UC) is an autoimmune disorder that’s a type of inflammatory bowel disease (IBD). It occurs when your immune system attacks your colon, causing chronic inflammation. In severe cases, it can cause ulcers in your colon lining. You may have periods of active disease (flares/relapses) and periods of mild or inactive disease.
It’s estimated that up to 1.5 million Americans may have UC. The condition can run in families and can start at any point in life. It usually develops between ages 20 and 30. About one fourth of all cases develop before age 20. The condition is more common among Caucasians than other races, particularly Ashkenazi Jews. Increasingly, however, Hispanics, Asians and African Americans are affected.
Through the Inflammatory Bowel Disease (IBD) Center at Beth Israel Deaconess Medical Center (BIDMC), we diagnose and treat UC in patients of all ages. We can help you reduce symptom flareups and enjoy longer periods of remission.
The cause of UC is unclear. Your genetic makeup, environment and immune system all could play a role in the development of the disease.
The most widely accepted theory is that your immune system overreacts to something in your gastrointestinal (GI) tract. This reaction increases the inflammatory cells in your intestines. Your immune system then doesn’t properly shut itself off, leading to chronic inflammation.
Researchers haven’t identified any specific diet as a direct cause of UC. However, there are dietary factors that may increase your risk of getting the disease. Diets high in sugar, refined carbohydrates and fat are all more common in patients diagnosed with ulcerative colitis than those without it. So are diets low in fiber, fruits and vegetables.
If you have UC, you’re likely to have bloody stools and diarrhea. These are other symptoms:
These symptoms can indicate other digestive disorders, as well, such as these issues:
It's important to make sure you get an accurate diagnosis. In young adults with ongoing diarrhea, infections of the colon are the most common cause. After infection is ruled out, doctors may shift their attention to UC as a potential cause.
Ulcerative colitis also can affect parts of your body outside your GI system. These symptoms are known as extraintestinal manifestations (EIMs). They occur in up to 25% of people with UC and can affect the following sites:
There is no single test to diagnose ulcerative colitis. We make a diagnosis using a combination of these methods:
We classify UC both by its location and severity. The best way for us to get this information is to perform a colonoscopy. Over time, the parts of the colon affected by UC and the severity of the inflammation can change. We use the following terms to classify the extent of UC:
These terms note the severity of UC:
Current treatment for UC focuses on suppressing your activated immune response. We work to find the treatment or treatments that are right for you. Our goal is to help you live comfortably and fully.
Medication usually can successfully treat UC. Less than 20% of people with UC need surgery to remove the colon (colectomy). In many cases, symptoms improve with medications taken by mouth. However, if your condition is limited to your rectum, you may feel better using enemas or suppositories.
Medications we may recommend:
Researchers have studied very few complementary therapies in clinical trials. But you may benefit from probiotics (foods or supplements that boost good bacteria in your body) or curcumin (a compound in turmeric). If you’re considering a complementary therapy, it’s best to discuss it with your doctor.
Some people also choose to make dietary changes. We recommend a healthy, balanced diet. Be sure to talk to your doctor before making major changes in your diet.
Restricting fruits and vegetables can lead to nutritional deficiencies and is not likely to improve your symptoms. You may need to reduce your dietary fiber during flares when diarrhea is severe. Only restrict dairy products if you know you have lactose intolerance.
Even with treatment, long-term UC increases your risk for other conditions. We work closely with you to monitor your well-being and keep you as healthy as possible.
Most people with UC have mild disease that’s controlled with medication. About 15-25% of patients have flare-ups that put them in the hospital at some point. If you have a serious flare-up, we treat it with intravenous steroids.
The cumulative risk of a disease flare is 60-70% over 10 years. About 10-20% of patients will require surgery to treat their ulcerative colitis.
Your risk of developing colorectal cancer increases after you’ve had UC for at least eight years. Your doctor may recommend routine surveillance colonoscopies every one to three years to reduce this risk. The following factors may further increase your risk:
You should start yearly colonoscopies right away if you’re diagnosed with PSC.
Mild thinning of the bones (osteopenia) occurs in up to 50% of people with UC. More severe thinning of the bones (osteoporosis) can occur in up to 15% of people. This complication is more common if you’ve required steroid therapy, are a smoker, or have low calcium and vitamin D intake.
We recommend a special X-ray called a bone mineral density scan (DEXA) if you fall into these categories:
If you have thinning bones, your doctor will examine you for other causes of bone loss, including an overactive thyroid and low levels of vitamin D. Your doctor may instruct you to take supplemental calcium and vitamin D on a daily basis. You may need other special medications (such as bisphosphonates) to prevent further bone loss, as well.
Your doctor may refer to an endocrinologist for further care.
Nutritional complications may occur if you have UC. These include deficiencies of protein, calories or vitamins. The deficiencies are caused by inadequate dietary intake, intestinal loss of protein or rectal bleeding as a result of the underlying inflammation.
Our nutrition specialists can help make sure you get the nutrients you need.
