Crohn’s disease is a type of . As many as have the condition, according to the Crohn’s & Colitis Foundation of America (CCFA).

More research about is necessary. Researchers aren’t sure how it begins, who is most likely to develop it, or how to best manage it. Despite major treatment advances in the last 3 decades, no cure is available yet.

Crohn’s disease most commonly occurs in the small intestine and the colon. It can affect any part of your , from the mouth to the anus. It can involve some parts of the GI tract and skip other parts.

The range of severity for Crohn’s is mild to debilitating. Symptoms vary and can change over time. In severe cases, the disease can lead to life threatening flares and complications.

Here’s everything you need to know about Crohn’s disease.

Crohn’s symptoms

The symptoms of Crohn’s disease often develop gradually. Certain symptoms may also become worse over time. Although it’s possible, it’s rare for symptoms to develop suddenly and dramatically. The earliest symptoms of Crohn’s disease can include:

  • feeling as if your bowels aren’t empty after a bowel movement
  • feeling a

It’s sometimes possible to mistake these symptoms for those of another condition, such as , an upset stomach, or an allergy. You should see your doctor if any of these symptoms persist.

The symptoms may become more severe as the disease progresses. More troublesome symptoms may include:

  • a , which causes pain and drainage near your anus
  • ulcers that may occur anywhere from the mouth to the anus
  • inflammation of the joints and skin
  • shortness of breath or decreased ability to exercise due to

Early detection and diagnosis can help you avoid severe complications and allow you to begin treatment early.

What causes Crohn’s disease?

It isn’t clear what causes Crohn’s disease. However, the following factors may influence your chances of developing it:

  • your immune system
  • your genes
  • your environment

Up to of people with Crohn’s disease also have a parent, child, or sibling with the disease, according to the CCFA.

According to a , certain factors can affect the severity of your symptoms. These include:

  • whether you smoke
  • your age
  • whether or not the rectum is involved
  • length of time you’ve had the disease

People with Crohn’s are also more likely to develop intestinal infections from bacteria, viruses, parasites, and fungi. This can affect the severity of symptoms and create complications.

Crohn’s disease and its treatments can also affect the immune system, making these types of infections worse.

are common in Crohn’s and can affect both the lungs and the intestinal tract. It’s important that these infections are diagnosed and properly treated with antifungal medications to prevent further complications.

Crohn’s diagnosis

No single is enough for your doctor to . They will begin by eliminating other possible causes of your symptoms.

Your doctor may use several types of tests to make a diagnosis:

  • Blood tests can help your doctor look for certain indicators of potential problems, such as anemia and .
  • A can help your doctor detect blood in your GI tract.
  • Your doctor may request an to get a better image of the inside of your upper gastrointestinal tract.
  • Your doctor may request a to examine the large bowel.
  • Imaging tests like and give your doctor more detail than an average . Both tests allow your doctor to see specific areas of your tissues and organs.
  • Your doctor will likely have a tissue sample, or , taken during an endoscopy or colonoscopy for a closer look at your intestinal tract tissue.

Once your doctor has completed reviewing all the necessary tests and ruled out other possible reasons for your symptoms, they may conclude that you have Crohn’s disease.

Your doctor may go on to request these tests several more times to look for affected tissue and determine how the disease is progressing.

The can provide options in your area if you need help finding a primary care doctor or a gastroenterologist.

Treatment for Crohn’s disease

A isn’t available yet, but the disease can be managed. A variety of treatment options exist that can lessen the severity and frequency of your symptoms.

Medications

Several types of are available to treat Crohn’s. and anti-inflammatory drugs are commonly used. More advanced options include , which use the body’s immune system to treat the disease.

The medications, or combination of medications, you need depend on your symptoms, your disease history, the severity of your condition, and how you respond to treatment.

Anti-inflammatory drugs

The two main types of anti-inflammatory drugs doctors use to treat Crohn’s are and . Anti-inflammatory drugs are often the first drugs you take for Crohn’s disease treatment.

You typically take these drugs when you have mild symptoms with infrequent disease flares. Corticosteroids are used for more severe symptoms but should only be taken for a short time.

Immunomodulators

An overactive immune system causes the inflammation that leads to the symptoms of Crohn’s disease. Drugs that affect the immune system, called , may reduce the inflammatory response and limit your immune system’s reaction.

Antibiotics

Some doctors believe may help reduce some of the symptoms of Crohn’s and some of the possible triggers for it.

For example, antibiotics can reduce drainage and heal , which are abnormal connections between tissues that Crohn’s can cause.

Biologic therapies

If you have severe Crohn’s, your doctor may try one of a number of to treat the inflammation and complications that can occur from the disease. Biologic drugs can block specific proteins that may trigger inflammation.

Surgery

If less invasive treatments and lifestyle changes don’t improve your symptoms, may be necessary. Ultimately, of people with Crohn’s disease will require surgery at some point in their lives, according to the CCFA.

Some types of surgery for Crohn’s include removing damaged portions of your digestive tract and reconnecting the healthy sections. Other procedures repair damaged tissue, manage scar tissue, or treat deep infections.

Diet

Food doesn’t cause Crohn’s disease, but it can .

After a Crohn’s diagnosis, your doctor will likely suggest making an appointment with a registered dietitian (RD). An RD will help you understand how food may affect your symptoms and how your may help you.

In the beginning, they may ask you to keep a . This food diary will detail what you ate and .

Using this information, the RD will help you create an eating plan. These dietary changes should help you absorb more nutrients from the food you eat while also limiting any negative side effects food may be causing.

Read on for more information on an eating plan for Crohn’s.

Crohn’s disease diet

A diet plan that works for one person with Crohn’s disease may not work for another. This is because the disease can involve different areas of the GI tract in different people.

It’s important to find out what works best for you. This can be done by keeping track of your symptoms as you add or remove certain foods from your diet. Lifestyle and diet changes may help you reduce the recurrence of symptoms and lessen their severity.

Adjust fiber intake

Some people need a high fiber, high protein diet. For others, the presence of extra food residue from high fiber foods such as fruits and vegetables may aggravate the GI tract. If this is the case, you may need to switch to a .

on this particular diet has been mixed, so speak with your doctor about your personal needs.

Limit fat intake

Crohn’s disease may interfere with your body’s ability to break down and absorb fat. This excess fat will pass from your small intestine to your colon, which can cause diarrhea.

However, a on mice suggested that a diet higher in plant-based fats had the potential to change the gut microbiome in positive ways for Crohn’s disease. More research is needed and your doctor or an RD can help guide you in your fat intake.

Limit dairy intake

Previously, you may not have experienced , but your body digesting some dairy products when you have Crohn’s disease. Consuming dairy can lead to an upset stomach, abdominal cramps, and diarrhea for some people.

Drink enough water

Crohn’s disease may affect your body’s ability to absorb water from your digestive tract. This can lead to . The risk of dehydration is especially high if you’re having diarrhea or bleeding.

Consider alternative sources of vitamins and minerals

Crohn’s disease can affect your intestines’ ability to properly absorb other nutrients from your food. Eating may not be enough. Talk with your doctor about taking multivitamins to find out if this is right for you.

Work with your doctor to figure out what best suits your needs. They may refer you to an RD or nutritionist. Together, you can identify your dietary plan and create guidelines for a balanced diet.

Natural treatments for Crohn’s

Some people use to help manage symptoms of various conditions and diseases, including Crohn’s disease.

The Food and Drug Administration hasn’t approved these for treatment, but some people use them in addition to mainstream medications.

Don’t add any new treatments to your current treatment plan without consulting your doctor.

Some include:

  • Probiotics. These are live bacteria that can help you replace and rebuild the good bacteria in your intestinal tract. may also help prevent microorganisms from upsetting your gut’s natural balance and causing a Crohn’s flare. Scientific data about effectiveness is limited.
  • Prebiotics. These are found in plants, such as asparagus, bananas, artichokes, and leeks, that help feed the good bacteria in your gut and increase their numbers.
  • Fish oil. is rich in omega-3s. According to a , research is ongoing regarding its possible treatment of Crohn’s disease. Oily fish like salmon and mackerel are rich in omega-3s. You can find online.
  • Supplements. Many people believe certain herbs, vitamins, and minerals ease the symptoms of a variety of diseases, including inflammation associated with Crohn’s disease. Research is ongoing as to which may be beneficial.
  • Aloe vera. Some believe that the plant has anti-inflammatory properties. Because inflammation is one of the key components of Crohn’s disease, people may use it as a natural anti-inflammatory. However, there is no current research that suggests aloe vera helps with Crohn’s.
  • Acupuncture. This is the practice of strategically sticking needles in the skin to stimulate various points on the body. A found that , combined with — a type of traditional Chinese medicine that involves burning dried medicinal herbs on or near your skin — improves symptoms of Crohn’s disease. More research is needed.

Tell your doctor if you use any CAM treatments or over-the-counter medications. Some of these substances can affect the efficiency of medications or other treatments. In some cases, an interaction or side effect could be dangerous, or even life threatening.

Crohn’s surgery

Surgery for Crohn’s disease is considered a last-resort treatment, but of people with Crohn’s will ultimately need some type of surgery to relieve symptoms or complications.

Once medications are no longer working or side effects have become too severe to treat, your doctor may consider one of the following surgeries.

  • widens and shortens the intestines in an attempt to reduce the effects of scarring or damage to the tissue.
  • During a , portions of damaged intestine are removed. Healthy intestine is stitched together to reform the intestines.
  • An creates a hole through which your body can eliminate waste. These are usually performed when a portion of the small or large bowel is removed. They can be permanent or temporary when your doctor wants to give your intestines time to heal.
  • A removes sections of the colon that are diseased or damaged.
  • A is surgery to remove the colon and rectum. If you have this surgery, you will also need a colostomy (a hole in the large intestine for emptying waste).

Crohn’s disease surgery is helpful for relieving symptoms, but it’s not without risk. Talk with your doctor about any concerns you may have with surgery.

What are the variations of Crohn’s disease?

There are six variations of Crohn’s disease, all based on location in the digestive system. They are:

  • Gastroduodenal Crohn’s disease. This uncommon condition mainly affects your stomach and the duodenum, which is the first part of your small intestine.
  • Jejunoileitis. This type occurs in the second portion of your intestine, called the jejunum. Like gastroduodenal Crohn’s, this variation is less common.
  • Ileitis. Ileitis involves inflammation in the last part of the small intestine, or ileum.
  • Ileocolitis. This affects the ileum and the colon and is the most common variation of Crohn’s.
  • Crohn’s colitis. This affects the colon only. Both ulcerative colitis and Crohn’s colitis impact the colon only, but Crohn’s colitis can affect deeper layers of the intestinal lining.
  • Perianal disease. This often involves fistulas, or abnormal connections between tissues, deep tissue infections, as well as sores and ulcers on the outer skin around the anus.

Crohn’s disease and ulcerative colitis

Crohn’s disease and are two types of IBD. They have many of the same characteristics. You may even mistake them for one another.

They have the following in common:

  • The first signs and symptoms of both Crohn’s disease and UC are very similar. These can include diarrhea, abdominal pain and cramping, rectal bleeding, weight loss, and fatigue.
  • Both UC and Crohn’s disease occur more commonly in people ages 15 to 35 and people with a family history of either type of IBD.
  • In general, IBD tends to affect all sexes equally, but this can vary depending on age.
  • Despite decades of research, scientists still don’t know what causes either disease. In both cases, an overactive immune system is a likely culprit, but other factors likely play a role.

Here’s how they differ:

  • UC only affects the colon. Crohn’s disease can affect any part of your GI tract, from the mouth to the anus.
  • UC only affects the outermost layer of tissue lining your colon called the mucosa. Crohn’s disease can affect all the layers of your intestinal tissue from superficial to deep.

UC is just one type of colon inflammation. Several other types of colitis exist. Not all forms of colitis cause the same type of intestinal inflammation and damage as UC.

Crohn’s disease statistics

The and the report the following statistics:

  • Around 3 million Americans have some form of IBD. This total includes over 780,000 Americans who have Crohn’s disease.
  • People who actively smoke are twice as likely to receive a diagnosis of Crohn’s disease.
  • If the condition is treated — medically or surgically — 50 percent of people with Crohn’s disease will go into remission or experience only mild symptoms within 5 years of their diagnosis.
  • About 11 percent of people who have Crohn’s will experience a chronically active disease.

The CCFA also reports:

  • In 2004, 1.1 million doctors’ office visits were for the treatment and care of Crohn’s disease.
  • In 2010, Crohn’s disease accounted for 187,000 hospitalizations.
  • The average person with Crohn’s disease will spend between $8,265 and $18,963 annually to treat or manage their disease, per 2003–04 U.S. insurance claims data.

According to :

  • Crohn’s disease occurs about as frequently in men as in women.
  • Two out of three individuals with Crohn’s disease will receive a diagnosis before the age of 40.

Crohn’s disease and disability

Crohn’s disease can disrupt your work and personal life. It can also cause financial stress. If you don’t have health insurance (and sometimes even if you do), your out-of-pocket expenses can total several thousand dollars per year.

If the disease becomes severe enough that it’s affecting your daily life in a significant way, consider filing for disability.

If you can prove that your condition prevents you from working or has prevented you from working for the last year, you may be eligible to receive disability income. Social Security Disability Insurance or Social Security Income can provide this type of assistance.

Unfortunately, applying for disability can be a long and tedious process. It requires lots of appointments with your doctors. You may have to pay for multiple doctors’ visits if you don’t have insurance. You’ll need to take time off of work if you’re currently employed.

Be aware that you may face a lot of ups and downs as you work through the process. You might even be denied and have to begin the whole process again. If you feel it’s the right choice for you, you can begin your Social Security application process by doing one of the following:

  • Apply .
  • Call the Social Security Administration’s toll-free hotline at 800-772-1213 Monday through Friday, 7 a.m. to 7 p.m.
  • Find and visit your .

Crohn’s disease in children

Most people with Crohn’s disease receive a diagnosis in their 20s and 30s, but IBD can develop in children, too. Approximately with an IBD show symptoms before age 20, according to a 2016 review.

Crohn’s disease that only involves the colon is common in children and adolescents. That means distinguishing between Crohn’s and UC is difficult until the child begins showing other symptoms.

Proper treatment for Crohn’s disease in children is important because untreated Crohn’s can lead to growth delays and weakened bones. It may also cause significant emotional distress at this stage in life. Treatments include:

  • antibiotics
  • aminosalicylates
  • biologics
  • immunomodulators
  • steroids
  • nutrition plans

Crohn’s medications can have some significant side effects on children. It’s vital you work closely with your child’s doctor to find the right options.

Outlook

Research is still ongoing to find more effective treatments and potentially an eventual cure for Crohn’s disease. But symptoms can be successfully managed and remission is possible.

Your doctor can help guide you in finding the right medications, alternative treatments, and lifestyle measures that can help.

If you’re having gastrointestinal symptoms, speak with your doctor to determine the cause and potential solutions.
