How To Diagnose Ibs And Crohns Disease

Inflammatory Bowel Disease vs Irritable Bowel Syndrome, Animation

Both conditions manifest with diarrhea and alternating bowel movements. IBS is a clinical diagnosis and can be diagnosed based on symptoms while Crohns disease is an inflammatory condition.

Crohns disease also called Crohns colitis is inflammation of the colon. It is diagnosed with the help of scans and colonoscopy.

How Can I Tell If I Have Ulcerative Colitis Or Crohns Disease

Its important that you, your healthcare provider, and a GI specialist work together closely to figure out whats causing your symptoms. This is especially important since the symptoms of Crohns disease and ulcerative colitis can be similar. Your providers may check blood work and a stool sample. To get an accurate diagnosis, your GI specialist may do a colonoscopy, where a camera is pushed into the colon. Your provider will look at the inside of the colon and take tissue samples, which are important for making the right diagnosis. Your providers might get a CT scan or an MRI of your abdomen to check for complications related to your condition.

Resources For People With Crohns Disease

Having Crohns disease can be physically and emotionally exhausting, and it can sometimes feel like no one else knows what youre going through.

At the same time, you may have questions about the best way to treat or manage your disease, or wonder if you could benefit from participating in a clinical trial.

Fortunately, a number of resources are available for information, emotional support, and even amusement related to Crohns disease.

Check out our list of websites, organizations, articles, and blogs related to Crohns. You can learn more about your treatment options, read about other peoples experiences with Crohns, and find out more about getting involved in research or advocacy.

What Is Inflammatory Bowel Disease

Inflammatory bowel disease is a group of autoimmune diseases that run the spectrum from ulcerative colitis to Crohn’s disease. Inflammatory bowel disease is a dysregulation in the body where the immune system attacks the bowel and causes inflammation.

The onset of inflammatory bowel disease may be triggered by a combination of a genetic predisposition and an illness or exposure to something in your environment that causes the immune system to attack the bowel and create inflammation.

Inflammatory bowel disease has two peak times for diagnosis in adults: people in their early 20s to 30s and people in their 50s and 60s.

Comparing Methods Of Diagnosis


Certain diagnostic tests and procedures can definitively diagnose Crohn’s and ulcerative colitis, according to the Crohn’s and Colitis Foundation. However, there are no specific tests that will conclusively diagnose IBS.

Irritable bowel syndrome

Your doctor will base an IBS diagnosis on your symptoms and how long you’ve had them. If you have experienced diarrhea and abdominal pain for three consecutive months or if you had these same symptoms off-and-on for 12 months, you may have IBS. Your doctor may also ask how often you have bowel movements, if there have been any changes in the consistency of your stool and if you experience significant relief with bowel movements. Although your doctor may order diagnostic testing and procedures, this would not be to diagnose IBS but rather to rule out other intestinal diseases, such as ulcerative colitis and Crohn’s.

Ulcerative colitis and Crohn’s disease

When diagnosing these two IBDs, your doctor may order several tests. These may include blood tests, stool samples and a colonoscopy, in which biopsies of suspicious areas will be taken. Additional tests may be needed for a Crohn’s diagnosis, such as an upper endoscopy, capsule endoscopy, CT, MRI or a balloon-assisted enteroscopy. These diagnostic imaging exams can help evaluate the small intestine, which can be affected by Crohn’s. These tests would not be necessary to diagnose ulcerative colitis because it only affects the large intestine.

Q How Are Ibs And Ibd Treated

Several medications are available and many promising drugs are under study as well. Doctors also recommend those with IBS communicate openly with to their caregivers about ongoing GI symptoms.

Medication to manage and prevent IBD flare-ups include biologics, which are medication therapies made from living organisms that help restore the bodys ability to fight the disease.

Surgery may be necessary when medications no longer control the symptoms of IBD. Surgical treatment removes the affected portion of the bowel, but occasionally a complete removal of the colon or rectum is considered.

Living With Irritable Bowel Syndrome

While irritable bowel syndrome cannot be cured, it doesn’t permanently harm the intestines and doesn’t cause cancer. Irritable bowel syndrome may affect your quality of life, so it’s important to learn about your symptoms and what you can do to control them.

The current understanding of irritable bowel syndrome indicates hypersensitivity in the gut causes the symptoms. This affects how your body perceives stimuli related to bowel function. Treatment focuses on relieving symptoms so you can live as normally as possible.

In most cases, you can successfully control mild symptoms of irritable bowel syndrome by learning to manage stress and making healthy changes to your diet and lifestyle. This includes exercising regularly, drinking plenty of fluids and getting enough sleep. Your health care team may prescribe other specific dietary changes, medications and supplementary treatments.

While living with irritable bowel syndrome can present daily challenges, your health care team is available to help. They can guide you through an appropriate evaluation of your symptoms and provide treatments to help you optimize your quality of life.

Summary Ibs Vs Crohns

Crohns disease is an inflammatory bowel disease characterized by the transmural inflammation of the colonic mucosa. A functional derangement of the intestines that gives rise to altered bowel habits and abdominal pain is identified as the irritable bowel syndrome. Inflammation is observed only in Crohns disease and not in IBS.

Common Symptoms You May Experience With Inflammatory Bowel Disease Are:

The Differences Between IBD, Crohns Disease, UC, and IBS
  • Urgent bowel movements
  • Cramping abdominal pain

Symptoms of inflammatory bowel disease may be experienced regularly and can significantly affect your quality of life. The treatment for inflammatory bowel disease is multifactorial. Treatment typically involves using immunosuppressive drugs to help the immune system avoid attacking the bowel. Dietary modifications can decrease inflammation.

Epidemiology Of Ibs And Ibdboth On The Rise In Asia

The incidence of CD in the world ranges from 5.0 to 10.7 per 100,000 person-years, while the incidence of UC ranges from 6.3 to 24.3 per 100,000 person-years. The marked variations are due to geographical localities, with Asia tending to show the lowest incidence rate, as compared to predominantly UC in Europe, and CD in North America.5 Even in Asia, with its large geographical area, there is variation in the annual incidence rate from 0.1 to 6.3 per 100,000 population for UC and 0.04 to 5.0 per 100,000 population for CD.5

Gender differences were reportedly equal in large population-based studies, although some contested a higher male preponderance for IBD in Asia.5,6 The highest incidence ages of diagnosis were recorded in the second to fourth decades, therefore implicating the most productive age group, with socioeconomic impact in terms of hours off work and impaired productivity.

IBS in Asia shows a prevalence rate of 2.9% to 15.6%, with no predilection for the traditionally female gender.7,8,9 The prevalence rate is highly dependent on the utilization of Manning or Rome-based criteria, and to a lesser extent on the geographical distribution. Age distribution still involves younger individuals in their early 20’s, comparable to Western studies.

However, for both IBS and IBD, the prevalence and annual incidence has shown a consistently increasing trend in Asia which is in keeping with a worldwide trend.

Where Is The Pain In Ibd Vs Ibs

Crohnâs disease, one of the main forms of IBD, usually causes pain in the lower right side of your belly. The other main form, ulcerative colitis, leads to pain in the left side of your belly. Both, however, can cause pain anywhere in the abdomen.

If you have IBS, you probably have pain or cramps in the lower half of your belly.

Q What Are The Symptoms Of Ibs And Ibd

Both are digestive conditions and affect the esophagus, stomach and intestines. IBS is a chronic syndrome made up of a group of symptoms. IBD, on the other hand, refers to inflammation or chronic swelling of the intestines.

IBS symptoms include chronic abdominal pain and changes in bowel habitsdiarrhea and constipation, or alternating between both. Symptoms can vary person to person and can often change over time, making it difficult to manage.

IBS does not develop into IBD or cause permanent harm in your intestines, such as intestinal bleeding, other intestinal diseases or cancer. But it can significantly affect your quality of life. Some have reported they would be willing to give up their essential pleasurescaffeine, use of cell phone and the internet and even sex to be free of IBS symptoms.

Common forms of IBD include Crohns disease and ulcerative colitis. Both cause chronic inflammation in the GI tract. These conditions can cause rectal bleeding and diarrhea, bloating, abdominal cramping, pain, reduced appetite, unintended weight loss and fatigue.

How Is Crohns Disease Diagnosed

Ulcerative Colitis vs Crohn

The first step to diagnosing Crohns disease is complete medical history, a physical exam, and a series of tests to rule out other conditions that may cause similar symptoms. These include irritable bowel syndrome , lactose intolerance, and ulcerative colitis.

During a physical exam, a physician will check for bloating, swelling, and painful or tender spots in your abdomen.

Additional tests are often needed to diagnose Crohns disease and may include: blood tests, stool tests, colonoscopy, upper GI endoscopy, wireless capsule endoscopy, and imaging tests like X-rays and computerized tomography scans.

What Causes Ulcerative Colitis And Who Gets It

Docs still cant pinpoint the precise cause of the disease, but its thought the following may contribute to ulcerative colitis:

  • the gut microbiome
  • other environmental factors

Research also suggests that it could be the result of an interaction between infections in the colon and the bods immune response. Basically, experts think the inflammation response is prolonged in patients with ulcerative colitis, which is what causes all those achy, breaky ulcers.

Though anyone can get ulcerative colitis, most people are diagnosed in their mid-30s. These people are also more likely to get it:

  • those with first-degree relatives with the disease

Causes Of Ibd And Ibs

Physical signs have helped doctors learn what causes IBD.

The long-lasting inflammation in the digestive tracts of people who have IBD can cause bleeding and ulcers . In turn, this irritation causes pain. That triggers the immune system, which leads to symptoms like fever and fatigue.

The causes of IBS arenât as clear. Scientists have found links to the immune system and how muscles move food through your gut. Many people have triggers that make their symptoms worse, including certain foods, stress, infections, and hormonal changes.

Ibd And Ibs Treatment

People who have IBD or IBS often try to treat it by changing what they eat. Thereâs no specific diet that works for everyone. Ask your doctor if it would help to:

  • Get more fiber .
  • Avoid lactose, which is in dairy products.
  • Cut down on foods that make you gassy or bloated.
  • Get more water.
  • Avoid caffeine and legumes .
  • Limit or avoid FODMAPs, a type of sugar found in some fruits, vegetables, breads, and dairy products.

Doctors usually treat IBD with drugs that target the inflammation:

  • Aminosalicylates work on the lining of your intestine. They help in mild or moderate cases of IBD.
  • Corticosteroids weaken your immune system. Youâll take them for a short time if your symptoms flare up.
  • Immunomodulators also affect your immune system. You can use them as a long-term treatment.
  • Biologic therapies keep proteins in your body from causing inflammation.
  • Antibiotics fight infection caused by the disease or from surgery to treat it.

These meds generally donât work for IBS, which is one reason why itâs so important to know which condition you have.

Some people who have IBD need surgery to repair the damage to their digestive tract, but those with IBS donât.

If you have IBS, your doctor may recommend over-the-counter or prescription drugs to help with diarrhea or constipation. These include laxatives or anti-diarrheals, antispasmodics, and antidepressants.

What’s The Difference Between Ibs And Ibd

Difference between IBS (Irritable bowel Syndrome) and IBD (Inflammatory bowel disease)

In some respects, IBS and IBD are easy conditions to confuse. On top of having similar sounding names, the two have many similar symptoms sufferers may experience abdominal pain, cramps, constipation and diarrhoea as well as feeling generally unwell.

That said, the conditions are quite distinct, with different causes and different treatments. This means if you’re experiencing bowel problems, it’s important to see a medical professional who can give you a definitive diagnosis.

Types Of Crohns Disease

There are several different types of Crohns disease, categorized by the area of the digestive tract affected.


Ileitis This form of Crohns disease affects only the ileum.

Crohns Colitis Also known as granulomatous colitis, this form of the disease affects only the colon.

Gastroduodenal Crohns Disease This form of the disease affects both the stomach and the beginning of the small intestine .


How Is Ibd Diagnosed

  • A combination of endoscopy or colonoscopy and imaging studies, such as:
  • Contrast radiography.
  • Types of common medications to treat IBD:
  • 5-aminosalicyclic acids.
  • Surgeries to remove damaged portions of the gastrointestinal tract.

    What To Offer These Patients

    The main challenge has always been to make a definitive diagnosis, but overlap between IBS and IBD can pose a problem. A colonoscopy with mucosal histopathological studies and/or Rome questionnaires may not be adequate to separate the two. Management consideration is shown in Fig. 2.

    Management consideration in IBS-IBD overlap. When considering progression or overlap of IBS-IBD, it is important to exclude undiagnosed or ongoing inflammation, and thus the need for biomarkers including fecal calprotectin and pathological assessment. Triggers for ongoing inflammation are also sought especially occult infection and psychological dysfunction which are often subtle and not noticed. It is also important to assess and treat other disorders of the gut-brain axis .

    With fecal calprotectin , it is potentially easier to distinguish between IBD, IBS, or the proposed early or pre-IBD condition with its low-grade inflammation. This can further be of use as a risk-stratifying method to ensure these patients are followed up, thereby preventing or controlling active IBD.

    Regulation of the gut microbiota as a potential trigger of IBS and IBD is also important. This therefore necessitates testing for SIBO or intestinal dysbiosis, and future strategies including the use of prebiotics, probiotics, or synbiotics are needed.

    Ibs And Crohns Disease:

    IBD &  IBS

    When a person or physician is talking about gastrointestinal diseases, you might end up hearing a bunch of terms like IBD or IBS. Both of these terms are confused with each as they sound a little similar.

    Irritable bowel syndrome is a non-inflammatory disorder, whereas chronic inflammatory bowel disease, sometimes known as IBD, includes both Crohns disease and ulcerative colitis.

    Since both of these terms are typically connected and confused, the diagnosis of each is also confused. To clear up the confusion, here are some key differences between them.

    What Is Ulcerative Colitis

    Ulcerative colitis is another type of IBD. Its also an autoimmune disorder. Unlike Crohns disease, ulcerative colitis only involves the colon, or large intestines. It only affects the inner lining of the colon, instead of the whole wall thickness.

    What are symptoms of ulcerative colitis?

    Symptoms of ulcerative colitis include:

    • Bloody or mucousy diarrhea

    These complications may need surgery to treat them.

    Common Questions & Answers

    While no two people will experience Crohn’s disease in the same way, most have diarrhea and abdominal pain or cramping. Other common symptoms include rectal bleeding, nausea, loss of appetite, an urgent need to use the bathroom, and constipation.

    Weight loss, fatigue, joint pain, red or itchy eyes, and inflamed or bumpy skin may also occur.

    There is no single diet for Crohn’s disease. However, common triggers you may want to avoid include whole grains, nuts and seeds, raw fruits and vegetables, spicy foods, fatty or greasy foods, dairy products, and caffeinated and alcoholic beverages.

    During a flare, when symptoms are at their worst, it may be helpful to stick to bland, soft foods.

    The first step in testing for Crohns is a physical exam, a full medical history, and tests to rule out other conditions, including lactose intolerance, irritable bowel syndrome, and ulcerative colitis.

    Blood tests, stool tests, colonoscopy, upper GI endoscopy, wireless capsule endoscopy, and imaging tests are also used to diagnose Crohn’s.
