What Part Of The Digestive System Does Crohn Disease Affect – Inflammatory bowel disease, or IBD, is characterized by chronic inflammation in the digestive tract. The two main types are ulcerative colitis and Crohn’s disease.
Inflammatory bowel disease, or IBD, is inflammation or swelling in the gastrointestinal tract and a lifelong immune response. The disease makes the body and the immune system think that food, bacteria and other necessary things should not be in the intestines. This causes the body to attack the intestinal cells, causing inflammation that does not go away easily. Nearly 3 million Americans have IBD, and the number of people affected continues to rise worldwide.

What Part Of The Digestive System Does Crohn Disease Affect
There are two main types of IBD: ulcerative colitis and Crohn’s disease. Both are diseases with periods of remission (when you feel good) and relapses (when you feel bad). Symptoms can vary from person to person and depend on the type of IBD.
Crohn’s Disease Vs Ulcerative Colitis: What’s The Difference?
Although IBD is a long-term health problem with periods of remission and relapses, most people have a normal life expectancy and a good quality of life. For those with chronic and persistent symptoms, here are some tips:
Ulcerative colitis (UC), which is more common than Crohn’s disease, is an inflammatory disease that affects the large intestine (rectum and colon). It can affect part or all of the colon. People with UC often have:
Some people with UC may have weight loss or other systemic symptoms (symptoms that affect the whole body). UC inflammation can also affect the joints or skin, causing joint pain and a skin rash. During a flare-up, symptoms may go beyond those affecting the digestive system, including:
Skin problems affect up to 15% of people with IBD. The disease can start slowly and progress over several weeks.
Crohn’s Disease Explained
AS can be characterized as remission (a time when symptoms improve) or mild, moderate, or severe activity. It can also be described as fulminant, meaning it is very active and unresponsive to therapy.
More than 10 bloody stools per day. There may be other symptoms, including abdominal bloating or the need for a blood transfusion.
UC is diagnosed by common symptoms, as well as by endoscopy and biopsy (a small tissue sample) of chronic inflammation of the colon. Learn more about ulcerative colitis.
Crohn’s disease can affect any part of the digestive tract, and the ileum (the last part of the small intestine) is the most common site of disease.
What Is Crohn’s Disease? Symptoms, Causes & Diagnosis
Crohn’s disease is often characterized by abdominal (stomach) pain, diarrhea, and weight loss, and sometimes by an abdominal mass, intestinal obstruction, or fistula. In approximately 20-25% of cases of Crohn’s disease, there may be a fistula. A fistula is an abnormal connection between the intestinal tract and another structure that usually occurs in the anal region, but a fistula can also occur in the normal bowel. Perianal disease (fistulae, fissures, or ulcers near the anus) has been reported to be more common in blacks, South Asians, and Hispanics.
The exact causes of Crohn’s disease are unknown, although certain genetic and environmental factors may increase the risk of the disease. Read more about Crohn’s disease.
Because IBD can be a progressive disease (meaning it can get worse over time), early diagnosis and treatment can make a difference. The time from when symptoms appear or when a person begins to feel unwell to diagnosis is important.
A diagnosis of IBD usually requires an examination by a gastroenterologist. Depending on your health insurance, this evaluation may require a referral from your primary care physician or authorization from your health insurance company.

A therapeutic window of opportunity, which means treatment at an earlier stage of the disease, is also important to prevent the disease from rapidly developing into more serious problems. This is important because diagnosis can often be delayed due to mistaken acceptance of other conditions, such as irritable bowel syndrome, lactose intolerance, or hemorrhoids. Limiting access to specialist care can also lead to delays in diagnosis and treatment.
The second reason the disease can progress is that treatments are not used as directed or are used incorrectly and deeper levels of control and remission are not achieved. According to recent studies, the median time from symptom onset to diagnosis was 8.3 and 4.5 months for Crohn’s disease and UC, respectively.
Treatment for IBD is different for everyone and depends on the exact location of the disease, the type of symptoms, and the severity of the disease. General goals of IBD treatment:
Gastroenterologists focus both on helping them achieve remission, which is the absence of symptoms, and on maintaining remission or preventing flare-ups.
Digestive System Diseases: Common, Rare, Serious Types
From a medical perspective, the goal of treating IBD is mucosal healing/deep remission, meaning you feel well and have no signs of inflammation. Mucosal healing, defined as the absence of disease activity or ulceration during colonoscopy or other imaging tests, is also increasingly important in the management of IBD.
When mucosal healing is achieved in both Crohn’s disease and UC, exacerbations, hospitalization, or surgery are less likely. Once remission is achieved, the medical team may adjust treatment to maintain remission.
Other long-term goals of treatment are to reduce long-term steroid use and the long-term risk of colorectal cancer (CRC). People with UC or Crohn’s disease that affects the colon are at greater risk of developing CRC compared to people without these conditions, but it can be prevented with proper treatment and regular colonoscopies. The risk of cancer is decreasing thanks to improved treatment and prevention strategies. Given that some IBD treatments can have rare but potentially serious side effects, gastroenterologists work with them to weigh the benefits and risks of different drugs against the risk of untreated or undertreated disease.
Risk stratification means finding people who are at higher and lower risk of complications. Early detection of these high-risk features can help prevent long-term problems. with complex diseases or high-risk features, including:
What Are The Different Types Of Crohn’s Disease?
If any of these high-risk features are present, it is essential that the disease is treated by an experienced gastroenterologist with experience that includes IBD.
Your healthcare team may order blood tests or stool tests to help make a diagnosis and to evaluate or measure your response to medications or to make sure medications are not having side effects.
Your gastroenterologist will often order imaging or radiological testing, such as a computed tomography (CT) scan or magnetic resonance imaging (MRI) to determine the extent of inflammation or if there is concern about an abscess or other complication of IBD.
Anti-inflammatory drugs used to control or reduce inflammation in the digestive tract. They work directly on the lining of the gut, especially for those newly diagnosed or with mild symptoms.
Abdominal Pain And Crohn’s Disease: Understanding Symptoms
Mesolamine, also known as 5-aminosalicylic acid (5-ASA), is an active ingredient believed to provide anti-inflammatory effects when taken orally (by mouth) or rectally (rectally). Examples:
Sulfasalazine, balsalazid, and olsalazine are oral medications that work differently to reduce inflammation of the colon (colon and rectum).
Mesolamine is available in many oral and rectal forms, each targeting different parts of the digestive tract. The most common side effects of 5-ASA are headache, diarrhea, bloating, and nausea. The use of 5-ASA should be regularly reviewed by a healthcare team for side effects.
Also known as steroids, powerful anti-inflammatory drugs used to treat moderate to severe relapses of IBD. They work by slowing down several inflammatory pathways.
Why Is Inflammatory Bowel Disease Increasing In Incidence And What Can Be Done About It?
Corticosteroids are available orally, rectally, and intravenously (the medicine is injected directly into a vein). When people take corticosteroids, their adrenal glands slow down or stop producing cortisol, a hormone that is naturally produced by the body’s adrenal glands.
Budesonide is part of a new class of corticosteroids called non-systemic steroids because they work in the gut rather than the whole body. By doing so, they cause fewer side effects. Budesonide capsules are designed to slow the release of budesonide until the drug reaches the ileum and ascending colon.
Side effects of corticosteroids depend on the dose and duration of treatment. They are recommended for short-term use only to achieve remission, as they are not effective in preventing flare-ups. Long-term or frequent use of these steroids is not recommended due to their unwanted side effects.
New glucocorticosteroid drugs have been introduced to achieve the same effectiveness as already available steroids, but with fewer side effects. Some common side effects of corticosteroids include:

Some long-term (meaning when steroids are used for more than six to 12 months) side effects include diabetes (poor blood sugar control) and osteoporosis (thinning of the bones).
Medicines that reduce the normal response of the immune system. These drugs are used to control severe symptoms or when steroids cannot be stopped. They are also used in combination with biological agents (see below). They are safe, but necessary for liver function and white blood cell count
