Crohn’s Disease: Symptoms, Treatment, Living With It & Diagnosis

The gastrointestinal system is chronically inflamed due to Crohn’s Disease, an inflammatory bowel illness. If you have been diagnosed with Crohn’s Disease or are interested in learning more about the condition, we are here to assist you.

Living with a chronic disease may be intimidating and frustrating. However, we can offer you information and tools to assist you in managing your physical and emotional Crohn’s disease symptoms.

A summary of Crohn’s Disease

Crohn’s Disease is a chronic gastrointestinal inflammatory illness. Understanding Crohn’s Disease will assist you, and your loved ones navigate the uncertainties associated with a new diagnosis.

Who is Influenced?

An estimated 3 million Americans suffer from IBD. Crohn’s Disease is equally likely to afflict males and women.

Although Crohn’s Disease can arise at any age, it is often diagnosed in teenagers and adults between the ages of 20 and 30.

Between 1.5% and 28% of patients with inflammatory bowel disease (IBD) have a first-degree family, such as a parent, child, or sibling, who also has one of the disorders.

Even though there is a genetic risk factor for IBD, it is hard to predict who will get Crohn’s Disease based on family history.

Crohn’s Disease can afflict individuals of various ethnicities. In recent years, Crohn’s Disease has grown among Hispanics and Asians. However, the condition is more prevalent among Caucasians.

Crohn’s Disease

It can affect any section of the GI tract, from the mouth to the anus, but often affects the end of the small intestine (ileum) and the beginning of the colon.

Can influence the total thickness of the intestinal wall

Intestinal inflammation can “skip,” or leave normal regions between sick gut patches.

Ulcerative Colitis

The condition only affects the colon, often known as the big intestine.

Affects just the colon’s innermost lining

Intestinal inflammation does not “skip.”

Variations in Crohn’s Disease

If you have been diagnosed with Crohn’s Disease, it is crucial to determine which portion of your GI tract is damaged. Even though symptoms of Crohn’s Disease might vary from person to person, the kind of Crohn’s you have influences the symptoms and consequences you may encounter.


The most prevalent kind of Crohn’s Disease. It affects the terminal ileum at the end of the small intestine and the colon, commonly known as the large intestine.

Possible symptoms include:

  • Colic and cramps
  • Abdominal discomfort in the middle or lower right quadrant
  • Significant weight reduction


This kind of Crohn’s Disease only affects the ileum.

Possible symptoms include:

  • Same as ileocolitis
  • In extreme cases, consequences may include fistulas or inflammatory abscesses in the lower right abdominal quadrant.

Gastroduodenal Crohn’s Disease

This variety affects the stomach and duodenum, the beginning of the small intestine.

Possible symptoms include:

  • Nausea
  • Vomiting
  • loss of hunger
  • Weight reduction


This kind is characterized by inflammatory patches in the jejunum, the small intestine’s top portion.

Possible symptoms include:

  • Mild to severe stomach discomfort and cramps after eating
  • Diarrhea
  • In extreme situations or after lengthy durations of inflammation, fistulas may occur.

Colitis (Granulomatous) de Crohn

Only the colon, often known as the big intestine, is affected.

Possible symptoms include:

  • Diarrhea
  • Rectal hemorrhage
  • Diseases around the anus, such as abscesses, fistulas, and ulcers.
  • Skin lesions and joint pains are more common in this form of Crohn’s than in others

Comparing Crohn’s Disease with Ulcerative Colitis

Although Crohn’s Disease and ulcerative colitis have similar symptoms and are both forms of inflammatory bowel disease (IBD), they are not the same Disease and affect separate parts of the gastrointestinal system.

  • Crohn’s illness
    • It can affect any section of the gastrointestinal system, from the mouth to the anus.
    • Can influence the total thickness of the intestinal wall
  • Ulcerative colitis
    • The condition only affects the colon and rectum (also known as the big intestine).
    • Affects the big intestine’s innermost lining.

What causes Crohn’s Disease?

An estimated 3 million Americans suffer from IBD. Unfortunately, the causes of Crohn’s Disease are poorly known. Therefore, the Crohn’s & Colitis Foundation works to advance Crohn’s disease research and discover a cure.

Here’s what we do know:

  • Men and women have an equal chance of being impacted.
  • Although Crohn’s Disease can arise at any age, it is more common in teenagers and adults between the ages of 15 and 35.
  • Diet and stress can exacerbate Crohn’s Disease, but they do not cause it.
  • A recent study indicates that genetic, environmental, and inherited variables contribute to the development of Crohn’s Disease.

Crohn’s Disease and the Immune System

The immune system of a human typically targets and destroys external invaders such as bacteria, viruses, fungus, and other microbes. During a typical immune reaction, blood cells go to the intestines and cause inflammation. Under normal conditions, harmless bacteria found in the gastrointestinal tract are shielded from an immune system attack.

In patients with IBD:

  • The immune system mistakes these innocuous bacteria for alien intruders and creates a defense against them.
  • The inflammation brought on by the immunological reaction persists. This results in persistent inflammation, ulceration, intestinal wall thickening, and finally, Crohn’s disease symptoms.

Genetic Variables

If you or a close relative has Crohn’s Disease, your family members are more likely to have the condition. Five to twenty percent of persons with inflammatory bowel disease have a first-degree family, such as a parent, child, or sibling, who also has one of the illnesses. Therefore, Crohn’s Disease carries a larger hereditary risk than ulcerative colitis.

Additional Genetic Risk Variants

When both parents have IBD, the chance of Crohn’s Disease or ulcerative colitis increases significantly.

The condition is particularly prevalent among individuals with eastern European ancestry, especially Jews of European heritage.

In recent years, there has been a rise in the number of instances recorded among African-American communities.

Environmental Factors

Living conditions appear to influence the development of Crohn’s Disease.

Here, Crohn’s Disease is more prevalent:

  • Developed nations, as opposed to developing nations
  • cities and towns as opposed to rural places
  • Northern climates, as opposed to southern ones

Symptoms and Indicators of Crohn’s Disease

Each patient may be affected by Crohn’s Disease differently. We are here to assist you in understanding Crohn’s disease’s most prevalent indications and symptoms. The symptoms you or a loved one may encounter depend on the afflicted portion of the GI system.

As Crohn’s is a chronic illness, patients will likely endure active symptoms, known as flares, followed by periods of remission in which they may feel no symptoms.

Although it is essential to detect the symptoms of Crohn’s Disease, only a Doctor can confirm the diagnosis. Therefore, please arrange an appointment with your Doctor to receive a diagnosis and treatment if you feel you may have inflammatory bowel disease (IBD).

Gastrointestinal Tract Inflammation

Crohn’s Disease can affect the whole gastrointestinal system, from the mouth to the anus. Inflammation in the GI tract caused by Crohn’s Disease manifests in various ways; however, several symptoms are typical.

  • Persistent diarrhea
  • Rectal hemorrhage
  • Urgent need to defecate
  • abdominal pains and discomfort
  • a feeling of incomplete bowel emptying
  • Constipation, which can develop into an intestinal blockage, is potentially life-threatening.

Complications of Crohn’s Disease

Although Crohn’s Disease affects the digestive tract, it can influence your entire health and lead to more significant medical complications.

  • loss of hunger
  • Weight reduction
  • low energy and exhaustion
  • Delay in children’s growth and development

In extreme circumstances, Crohn’s Disease can result in life-threatening consequences.

  • Fissures are rips in the anus lining that can cause discomfort and bleed, particularly during bowel movements.
  • A fistula is an irregular channel that arises between two parts of the intestine or between the gut and the bladder, vagina, or skin due to inflammation. Anal fistulas are the most prevalent and require prompt medical care.
  • A stricture is an intestinal constriction caused by persistent inflammation.

Symptoms Beyond the Digestive System

Inflammatory bowel disease (IBD) can induce systemic symptoms outside the GI tract that negatively impact your health and quality of life.

  • Redness or pain in the eyes, or vision changes
  • Mouth ulcers
  • aching and swollen joints
  • Skin problems, such as pimples, blisters, and rashes.
  • Fever
  • loss of hunger
  • Weight Loss
  • Fatigue
  • Night perspiration
  • Absence of a regular menstrual cycle
  • Osteoporosis
  • Kidney stones
  • Cirrhosis and primary sclerosing cholangitis are rare liver problems.

Crohn’s Disease Diagnosis and Testing

The symptoms of Crohn’s Disease vary greatly from person to person. We are at your side throughout the diagnostic procedure, informing you of what to expect at each stage.

There is no one test to establish a Crohn’s disease diagnosis, and the symptoms are frequently identical to those of other illnesses, such as bacterial infection. Therefore, your healthcare professionals must assess your current medical history and utilize diagnostic test results to determine possible reasons for your symptoms. This procedure might be time-consuming.

Consult your Doctor immediately if you or a loved one have symptoms that might indicate Crohn’s Disease.

Initial Testing and Assessment

The initial stage in diagnosis and therapy is a comprehensive physical examination. Next, your Doctor will chat with you and inquire about your general health, food and nutrition, family history, and daily activities.

What to to Expect

  • Your Doctor may arrange diagnostic tests to check for indications of Crohn’s Disease and rule out other potential medical disorders.
  • Blood and stool testing will likely be the first diagnostic procedures you undergo.
  • Additional testing may include upper and lower GI tract X-rays. In addition, your Doctor may propose a test that utilizes a contrast agent to provide a clearer, more comprehensive image of your gastrointestinal system. The contrast utilized varies for each test.
  • Consider taking a dependable relative or close friend with you to your appointments. This may help reduce your anxiety and improve your ability to recall information from your doctor.

Communication Guidance

  • Please write down your symptoms and bring them to your visits, so you don’t overlook anything vital.
  • Ask your healthcare staff which test is most appropriate for you, then contact your insurer to learn about cost coverage.

Endoscopy and Imaging

Your Doctor may prescribe further tests to examine your gastrointestinal system and intestines. Although these examinations are more intrusive and may seem terrifying, they are frequently performed in an outpatient environment, and your health care professionals will take precautions to reduce your pain.


Your Doctor may propose an endoscopy to examine the interior of your colon using a tiny camera attached to the end of a lighted tube.

Endoscopies used for testing Crohn’s Disease include:

  • A colonoscopy enables Doctor to inspect the colon, the lowest portion of the large intestine, by inserting a flexible, lighted tube through the anorectal hole.
  • During an upper endoscopy, a flexible, lighted tube is placed through the mouth, down the esophagus, into the stomach, and as far as the duodenum, the first segment of the small intestine. This allows the Doctor to view the gastrointestinal system from the top down.

Colonoscopies involve the preparation of the colon. Discuss with your healthcare staff how to prepare and strategies to make this preparation simpler.


During a colonoscopy or endoscopy, your Doctor may request a tissue sample from your colon or another section of your GI tract. During the biopsy, a tiny sample of tissue from the inside of the gut is extracted for further testing and analysis.

  • Your biopsied tissue will be evaluated for Disease at a pathology laboratory. In addition, biopsies are also utilized to detect colorectal cancer.
  • Although a biopsy sounds frightening, technological advancements have rendered this process painless.


During a colonoscopy, your doctor may employ this approach to search for polyps or precancerous alterations.

A blue liquid dye is injected into the colon during chromoendoscopy to highlight and identify minute changes in the lining of the gut.

After that, polyps can be excised and/or biopsied.

It is typical to see blue stools after this surgery.

Small Intestine Imaging

These tests check areas of the intestine that are difficult to see during a colonoscopy or endoscopy. They function by ingesting an oral contrast that is visible on a fluoroscopic X-ray, computed tomography (CT) scan, or magnetic resonance imaging (MRI) scan (MRI).

  • These tests may also be referred to as enterography and enteroclysis.
  • Your doctor may have you swallow a small, pill-sized camera that captures images of your small intestine and colon as it goes through your gastrointestinal tract. Eventually, the camera is ejected with a bowel movement.
  • A balloon endoscopy may be necessary to examine inaccessible regions of the gut.

Communication Guidance

  • Ask your healthcare professionals what you may anticipate throughout the process and whether there are any potential dangers to consider.
  • The majority of Crohn’s disease testing is performed in an outpatient environment. Consider having a friend or family member drive you to calm your worries and keep you company.

Crohn’s Disease Treatment Options

A mix of therapy choices can help you maintain illness control and live a full and satisfying life. However, remember that no universal therapy is effective for all patients. Each patient’s situation is unique, and treatment must be adapted accordingly.

Medication, dietary changes, and surgery may treat Crohn’s Disease and other IBD types.


Medication for Crohn’s Disease is intended to control the aberrant inflammatory response of your immune system causing your symptoms. In addition to alleviating typical symptoms such as fever, diarrhea, and discomfort, reducing inflammation permits intestinal structures to repair.

In addition to suppressing and managing symptoms (inducing remission), medication can be used to reduce the frequency of symptom flare-ups (maintaining remission). With adequate therapy over time, remission periods can be prolonged, and symptom flare-up periods can be diminished. Today, a variety of medications are utilized to treat Crohn’s Disease.

Combinational Treatment

In some situations, a health care Doctor may consider adding an extra therapy that will enhance the success of the previous therapy. Combination treatment might, for instance, involve the addition of a biologic to an immunomodulator. However, as with every medicine, combination therapy has both dangers and advantages. Combining medications may boost the efficacy of IBD therapy but may also raise the likelihood of adverse effects and toxicity. Your health care practitioner will determine the therapy choice that best meets your specific health care requirements.

Diet & Nutrition

Although adverse responses to certain foods may not cause Crohn’s Disease, paying close attention to your diet may help lessen symptoms, replenish lost nutrients, and promote recovery.

It is crucial for persons diagnosed with Crohn’s Disease to maintain a healthy diet, as the condition frequently suppresses appetite while raising the body’s energy requirements. In addition, frequent Crohn’s symptoms like diarrhea can impair the body’s capacity to absorb protein, fat, carbs, water, vitamins, and minerals.

Many individuals with Crohn’s Disease find that soft, bland meals produce less discomfort than those that are spicy or heavy in fiber. Your diet may remain flexible and should contain a range of foods from all food categories, but if you are lactose intolerant, your doctor will likely advise you to limit your dairy consumption.

Two-thirds to three-quarters of patients with Crohn’s Disease will require surgery at some point in their life, even with good medicine and nutrition. While surgery cannot cure Crohn’s Disease, it can save sections of the gastrointestinal system and restore the highest quality of life.

Surgery is required when drugs can no longer treat symptoms or if you develop a fistula, fissure, or intestinal blockage. Surgical procedures sometimes entail removing the diseased portion of the gut (resection) and then joining the two ends of the healthy bowel (anastomosis). Although these operations may alleviate your symptoms for many years, Crohn’s Disease usually reappears later in life.

Important details regarding surgery:

  • Studies indicate that 18 percent of Crohn’s patients may require surgery over the course of 5 years. However, this portion has decreased dramatically during the past many years.
  • Depending on the cause, illness intensity, and disease location, many types of operations may be done.
  • Ten years after their initial resection, roughly 31 percent of individuals with Crohn’s Disease may require a second resection.

Making Knowledgeable Decisions

If you are bewildered by all the available drugs and treatments, you are not alone! It is essential to discuss the risks and advantages of all treatment choices with your doctor due to the complexity of IBD.

Questions for Your Doctor

Upon receiving a diagnosis of Crohn’s Disease, it is natural to feel unsure and anxious. Many parts of your life may be affected by Crohn’s Disease in ways that might alter over time.

The greatest approach to preparing for a life with Crohn’s Disease is to become as knowledgeable as possible about the condition. These questions will assist you in initiating a conversation with your healthcare professional. The more knowledgeable you are about Crohn’s Disease, the better equipped you will be to manage your condition and lead the life you want to live.
