However, there are cases where the diagnosis of one form of IBD over the other is very difficult. At times, a final diagnosis is possible only after an event during the course of the disease or its treatment makes the form of IBD readily apparent.

Patients with IBD may be very confused as to the differences between these diseases. As with any chronic condition, education is an important tool to become an active participant in one’s own treatment plan.

If your diagnosis isn’t firm, don’t panic. In some people, it can take time to determine if the IBD is more like Crohn’s disease or more like ulcerative colitis. In about 5-20% of cases, people are diagnosed as having indeterminate colitis .

IBD is becoming increasingly treatable and there are now many medications in the arsenal that are helping people with all forms get greater control over their disease. The main differences between ulcerative colitis and Crohn’s disease are described below.

  • Smoking can worsen condition

Duration And Choice Of Treatment

Long-term treatment to maintain the patient in a state of remission should be provided to all patients with Crohns disease and ulcerative colitis .

With respect to the choice of drugs and the timing of their use, some of the professional societies favor a stratified approach. The usefulness of a “treatment pyramid” of this type is currently debated, because there is evidence from other specialties that the early administration of highly potent drugs such as anti-TNF biological agents may prevent late complications. On the other hand, treatment with immune modulators and biologics confers a cumulative risk of infections, lymphoma, and other types of malignancy, particularly in adolescents . It remains to be seen whether early, aggressive treatment can be applied successfully in this area of gastroenterology .

There is also a lack of consensus with respect to the optimal duration of treatment and to certain types of combination therapy. For the purine analogs, for example, some professional societies recommend temporary cessation of treatment under certain conditions after 2 years of remission and a total of 4 years of treatment , while the author and other experts recommend continued treatment.

Crohns Disease And Ulcerative Colitis And Digesting Food

Your mouth and stomach break down food by mechanical and chemical means. When the food has reached a pulp-like consistency, it is slowly released into the first part of the small intestine . The food is then massaged along the length of the small intestine. Organs like the pancreas and the gall bladder make digestive enzymes to further break down the food into its simpler components.

  • Crohns disease an inflamed ileum impairs absorption of vitamin B12 and bile salts. Inflammation along the length of the small intestine impairs absorption of all food nutrients. Inflammation of the large bowel impairs water absorption, causing diarrhoea.
  • Ulcerative colitis digestion and absorption are generally not affected. Inflammation of the large bowel impairs water absorption, causing diarrhoea.

Other factors that may affect your nutritional status include:

  • Medication some medication used to treat IBD may lessen your appetite and interfere with the absorption of certain nutrients, such as folic acid.
  • Inflammation your body needs greater amounts of nutrients in order to cope with inflammation and fever.
  • Surgery some people with IBD need surgery to remove parts of their small intestine. This lessens nutrient absorption.

What Are The Causes Of Ibd And Ibs

The exact causes of both IBD and IBS are not clear. With IBD, your genes play a strong role, and it runs in families. There are also many other things that can contribute, such as certain foods, smoking , and missing medication doses. With IBS, many factors are thought to be involved, but stress and diet play a big role. Sometimes people develop IBS after infections as well.

Ibd Research And Clinical Trials

Key Differences: The Symptoms

While the two diseases are similar, there are also a few notable differences that set them apart including some of their symptoms and where the inflammation develops. Only a health professional will be able to determine which type of IBD you have, so its important to explain all your symptoms to your doctor or GI specialist.

While their symptoms may seem similar on the surface, Everyday Health points out that ulcerative colitis is mostly characterized by blood stool with mucus and frequent diarrhea, whereas Crohns disease is often marked by nausea, weight loss, and vomiting, with only occasional rectal bleeding, and diarrhea. Crohns can also cause mouth sores, or inflammation of the skin, joints, and eyes which are not symptoms of ulcerative colitis.

What Are The Types Of Crohns Disease

Crohns disease can affect different sections of the digestive tract. Types of Crohns disease include:

  • Ileocolitis: Inflammation occurs in the small intestine and part of the large intestine, or colon. Ileocolitis is the most common type of Crohns disease.
  • Ileitis: Swelling and inflammation develop in the small intestine .
  • Gastroduodenal: Inflammation and irritation affect the stomach and the top of the small intestine .
  • Jejunoileitis: Patchy areas of inflammation develop in the upper half of the small intestine .

Who Is At Risk For Crohns Disease

Inflammatory Bowel Disease – Crohns and Ulcerative Colitits

There are certain factors which can raise your risk of Crohns disease:

  • Family history of the disease. Having a parent, child, or sibling with the disease puts you at higher risk.
  • Smoking. This may double your risk of developing Crohns disease.
  • Certain medicines, such as antibiotics, birth-control pills, and nonsteroidal anti-inflammatory drugs such as aspirin or ibuprofen. These may slightly increase your chance of developing Crohns.
  • A high-fat diet. This may also slightly increase your risk of Crohns.

Effects Of Crohns Disease And Ulcerative Colitis

Every person responds differently to IBD. The severity of symptoms will vary from time to time and from person to person. IBD is not a progressive disease . Rather, flare-ups can range from mild to severe and back to mild again. Some people will experience periods of relief from symptoms in between flare-ups.We cannot predict how long a person will stay free from symptoms, or when their next flare-up will occur. Some flare-ups settle down quite quickly with treatment. Other times, it may take months for a persons symptoms to respond to treatment.IBD interferes with a persons normal body functions. Signs and symptoms can include:

  • pain in the abdomen
  • delayed or impaired growth in children.

What Is The Difference Between Crohns Disease And Ulcerative Colitis

Both Crohns disease and ulcerative colitis are inflammatory bowel diseases , however, there are distinct differences between these diseases. This video developed by the GI Society with Dr. Mike Evans, illustrates the differences between Crohns disease and ulcerative colitis, the impact of these diseases, possible causes and prevalence.

Symptoms Associated With Ulcerative Colitis

During a UC flare up, the individual experiences continuous inflammation within the inner lining of the colon and rectum. This inflammation leads to the development of ulcers on the surface of the lining. These ulcers usually produce blood and mucus.

Inflammation typically starts in the lower section of the colon, including the rectum.

With ulcerative colitis, there are no healthy patches between the inflamed sections of colon.

Individuals with ulcerative colitis tend to experience pain in their lower abdominal area.

Video Chat: Crohns Disease 101

Crohns disease belongs to a group of conditions known as inflammatory bowel diseases, or IBD. It is named after Dr. Burrill B. Crohn, who first described the disease in 1932 along with his colleagues, Dr. Leon Ginzburg and Dr. Gordon D. Oppenheimer.

How Effective Is It

A large clinical trial looked at how well upadacitinib works in adults with moderately or severely active Ulcerative Colitis. The trial compared upadacitinib to dummy treatment . The trial found:

  • After 8 weeks of treatment, 30 in every 100 people who had upadacitinib were in remission. Only 4 in every 100 people who had placebo were in remission.
  • In this trial, people who responded to 8 weeks of upadacitinib either carried on taking it or switched to placebo. After 52 more weeks of treatment, 47 in every 100 people who carried on taking upadacitinib were in remission. This compared to 12 in every 100 people who switched to placebo.
  • The rate of serious side effects was lower in people taking upadacitinib than in people taking placebo.

Nicotine And Ulcerative Colitis

Ulcerative colitis is largely referred to as a disease of non-smokers. Former smokers are at the highest risk for developing ulcerative colitis, while current smokers have the least risk. This tendency indicates that smoking cigarettes may prevent the onset of ulcerative colitis.

Researchers have discovered that it is the nicotine in tobacco cigarettes that have a positive influence on symptoms of ulcerative colitis. Nicotine is a naturally occurring substance in tobacco that has a complex effect on many organs and systems in the body. Nicotine is also highly addictive, and many people who smoke cigarettes have difficulty quitting despite serious health risks.

It is theorized that the nicotine in cigarettes affects the smooth muscle inside the colon. This effect may alter gut motility .

Ulcerative colitis and Crohn’s disease are the two main forms of inflammatory bowel diseases , both characterized by chronic inflammation of the digestive tract. Although they share many similarities, there are key differences between the two diseases, according to the Crohns and Colitis Foundation.

Both conditions can cause significant health challenges and be difficult to manage without an expert doctor to help properly diagnose and treat which specific disease you have.

How Is Crohn’s Disease Diagnosed

Most people with Crohns first see a healthcare provider because of ongoing diarrhea, belly cramping or unexplained weight loss. If you have a child who has been experiencing the symptoms of Crohns disease, reach out to your pediatrician.

To find the cause of your symptoms, your healthcare provider may order one or more of these tests:

  • Blood test: A blood test checks for high numbers of white blood cells that may indicate inflammation or infection. The test also checks for low red blood cell count, or anemia. Approximately one in three people with Crohns disease have anemia.
  • Stool test: This test looks at a sample of your stool to check for bacteria or parasites. It can rule out infections that cause chronic diarrhea.
  • Colonoscopy: During a colonoscopy, your doctor uses an endoscope to examine the inside of your colon. Your doctor may take a tissue sample from the colon to test for signs of inflammation.
  • Computed tomography scan: A CT scan creates images of the digestive tract. It tells your healthcare provider how severe the intestinal inflammation is.
  • Upper gastrointestinal endoscopy: Your doctor threads a long, thin tube called an endoscope through your mouth and into your throat. An attached camera allows your doctor to see inside. During an upper endoscopy, your doctor may also take tissue samples.
  • Upper gastrointestinal exam: X-ray images used during an upper GI exam allow your doctor to watch as a swallowed barium liquid moves through your digestive tract.

Cd Affects Your Entire Gi Tract

  • Bowel obstruction

The inflammation of CD can also cause your colon to narrow significantly, a complication known as the quill sign because your intestines may be no wider than a turkey quill in places. This narrowing obstructs your bowels and may make it difficult to pass feces.

In addition, the inflammation associated with CD may affect other areas of your body. You may have:

  • Painful, red eyes

Ulcerative Colitis And Crohns Disease

Inflammatory bowel disease includes a number of conditions in which the immune system mistakenly attacks the intestines and triggers inflammation of the tissues. There are two main kinds of IBD: ulcerative colitis and Crohns disease. Today many medications are available to successfully treat IBD. These therapies work to calm inflammation, reduce and even alleviate symptoms, decrease flare-ups, and help you better cope with your condition. This report provides insight into the possible causes and complications of IBD, how you are diagnosed, and the steps you can take for better care so you can live your best life.

Diagnosis And Assessment Of Disease Activity


The diagnoses of Crohns disease and ulcerative colitis are made on clinical grounds supplemented with objective findings of radiological, endoscopic, and histological examination. In some cases, the diagnostic evaluation must be repeated after a certain period of time has passed. There is no gold standard for diagnosis . When establishing the diagnosis, one must exclude other inflammatory, toxic, vascular, neoplastic, and infectious etiologies of enteritis and/or colitis .

What Causes Uc And Crohn’s

The causes of both UC and Crohn’s disease is not fully understood. Several factors may contribute to the development of the disease, including:

  • Genetic factors
  • Both UC and Crohn’s disease tend to run in families
  • Having a first-degree relative who has the IBD is a risk factor for developing IBD

Crohns disease is more common in developed countries, urban cities and towns, and northern climates.

What Is Ulcerative Colitis

Ulcerative colitis affects just the large intestine and rectum. Thats where inflammation and ulcers develop. The inflammation prevents water from being reabsorbed into the bloodstream. The result is diarrhea.

If you have ulcerative colitis, you may have:

  • Stomach pain and cramping
  • Urgent need to go to the bathroom

Inflammation and ulceration cause bleeding, which is why there is often blood mixed in with the diarrhea. You also may experience nausea, fatigue, weight loss, and loss of appetite. As with Crohns disease, symptoms varylargely depending on the part of the large intestine that is involved. Unlike Crohns disease, which has clear sections of the colon , ulcerative colitis moves in a continuous way along the colonwith no skipped areas.

Ulcerative colitis that involves only the rectum is called proctitis. If the disease affects the left side of the colon, it is referred to as leftsided colitis. If it involves the entire colon, it is called pancolitis.

Inflammation In Other Areas

Some people with IBD have painful inflammation in other areas of the body, including:

  • joints of the fingers, hands, feet, ankles and knees
  • joints of the spine, including vertebrae and sacroiliac joints

Two specific skin problems that can occur as a result of IBD are:

  • pyoderma gangrenosum small, sunken ulcers on the skin
  • erythema nodosum painful, small, reddened nodules on the skin .

Smoking And Crohns Disease

Crohn’s vs. Ulcerative Colitis

The initial observation that smoking is associated with an increased risk of Crohns disease was made shortly after the link between ulcerative colitis and smoking was established,subsequent studies have shown a greater risk of Crohns disease in current smokers than non-smokers. Logan summarised the relative risk of Crohns disease in patients, relative to never smokers at diagnosis, as 2.7 for current smokers, 1.5 for ex-smokers, and 2.4 for those who had ever smoked during their life. A meta-analysis on seven suitable studies of Crohns disease confirmed a pooled odds ratio and a 95% confidence interval of 2.0 for current smokers compared with life time non-smokers, and 1.83 for former smokers compared with life time non-smokers. In this non-smoking group the risk was greatest for those who had quit smoking within four years of developing Crohns disease, and least for those who had been non-smokers for more than 10 years. The relative risk associated with smoking for women may be greater than for men: one study demonstrated a threefold difference. The site of Crohns disease has been linked with the duration of smoking habit and number of cigarettes smoked, suggesting that small bowel and ileocolonic disease are more common in heavy smokers.
