The primary goal in treating Crohn's disease is to control acute flares of the disease and to maintain remission for as long as possible. The specific type of treatment often depends on how severe the symptoms are. For example, people with mild-to-moderate symptoms are usually treated with medications that reduce swelling and suppress the immune system. More severe cases may require surgery.
Many people with inflammatory bowel diseases use complementary and alternative remedies in addition to prescription medications. Preliminary studies suggest that lifestyle changes, dietary adjustments (such as eating a rich variety of fruits and vegetables and avoiding saturated fat and sugar), and specific herbs and supplements may be useful additions to treatment.
Many people with Crohn's disease report that stress makes their symptoms worse. Relaxation techniques and mind/body exercises, such as yoga, tai chi, and meditation, are worth considering, particularly when used with other forms of treatment. In addition, studies suggest that hypnosis may improve immune function, increase relaxation, reduce stress, and ease feelings of anxiety.
Exercise helps people with Crohn's disease, both in terms of maintaining health and reducing stress. Exercise is considered safe for people with Crohn's disease, but anyone with a chronic illness should talk to their doctor before starting a new exercise or fitness regimen. It is especially important for people with Crohn's disease to drink water before and during exercise to prevent dehydration. Avoid extreme changes in body temperature during exercise.
Cigarette smoking is a risk factor for Crohn's disease and studies have shown that it may worsen symptoms. If you smoke, you should quit. Ask your doctor for help.
Although medications cannot cure Crohn's disease, they can reduce symptoms and help you control your condition. Sometimes, they can bring on remission of the disease for a while. Medications commonly used to treat Crohn's disease include:
- Sulfasalazine (Azulfidine) -- An older drug that reduces inflammation during acute flare ups and is usually taken with folic acid. Side effects include abdominal discomfort, nausea, and lowered sperm count. Sulfasalazine can be effective, but newer drugs are available.
- Mesalamine (Asacol, Rowasa) -- This drug reduces inflammation during acute flare ups and helps prevent recurrences. It generally has fewer side effects that sulfasalazine.
- Corticosteroids (such as budesonide, prednisone, and prednisolone) -- These drugs can reduce inflammation throughout your body but have many side effects, including acne, and an increased risk of infection, osteoporosis, high blood pressure, excessive hair growth, diabetes, and disorders of the eye including glaucoma and cataracts. Budesonide (Entocort) may have fewer side effects. Corticosteroids also suppress your body's production of the hormone cortisol and cannot be stopped abruptly. They are not for long-term use, but may be used to control flares.
- Immune system suppressors -- These medications decrease inflammation by suppressing the immune system. They are sometimes used in combination with steroids to reduce the dose of the steroid medication. These drugs can take several months to work, and all may have significant side effects. Drugs include azathioprine (Imuran), methotrexate (Rheumatrex), infliximab (Remicade), adalimumab (Humira), certolizumab pegol (Cimzia), natalizumab (Tysabri), and cyclosporine.
- Antibiotics -- Antibiotics may be prescribed to help treat fistulas and ulcers. Ciproflaxin (Cipro) and metronidazole (Flagyl) are most commonly used.
- Antidiarrheal medications (such as diphenoxylate, loperamide, or psyllium) -- Medications used to treat diarrhea must be used only under your doctor's supervision and with extreme caution. They can slow down the normal movements of the gastrointestinal tract and, in severe cases, may cause a life threatening complication known as toxic megacolon.
Although surgery will not cure Crohn's disease, 3 - 4 people with the condition will eventually have resections (parts of their colons removed) to close fistulas or to remove a severely damaged part of the intestine. In some cases, doctors can perform laparoscopic surgery (which uses a smaller incision), leading to fewer complications and shorter hospital stays. Strictureplasty, in which a doctor inserts a balloon into the intestine and expanded, is sometimes done when the intestine has become too narrow from scar tissue.
Complementary and Alternative Therapies
People with Crohn's disease often cannot absorb all the nutrients their bodies need, due to damage in the intestine. Abdominal pain and nausea may make it hard for them to eat. Some medications may also lower important nutrients in the body. For example, sulfasalazine reduces the body's ability to absorb folate, and corticosteroids can reduce calcium levels. Making sure you get enough nutrients is a crucial part of treating Crohn's disease. People with significant malnourishment, severe symptoms, or those awaiting surgery may require parenteral (intravenous) nutrition.
Although diet cannot cause or cure Crohn's disease, some studies suggest that people who eat foods high in saturated fat and sugar or who eat processed foods may be more likely to develop the disease. Certain foods may also reduce symptoms and make recurrences of the disease less likely.
- Eating fruits and vegetables, lowering fat, and eliminating sugar may reduce the risk of developing Crohn's disease. Although a low-fiber diet is one of the risk factors for developing Crohn's disease, some people with Crohn's disease find that fiber makes symptoms worse. If fiber bothers you, steam or bake your vegetables rather than eating them raw, and avoid high-fiber fruits, such as apples.
- Certain foods may aggravate symptoms of Crohn's disease – most often, dairy products, fats, and spicy foods. People with Crohn's disease may want to avoid these foods.
- Eat antioxidant foods, including fruits (such as blueberries, cherries, and tomatoes) and vegetables (such as squash and bell peppers).
- Eat foods high in B vitamins, calcium, and magnesium, such as whole grains (if not bothered by fiber), dark leafy greens (such as spinach and kale), and sea vegetables.
- Avoid refined foods, such as white breads and pastas.
- Eat 5 - 6 smalls a day.
- Avoid caffeine, alcohol, and tobacco.
- If symptoms are severe, an elemental diet may be recommended. Elemental formulas are liquid diets that contain only the basic building blocks of food and do not need to be broken down into smaller substances along the digestive tract. Some people find it hard to stick to an elemental diet, but after a period of time, often other foods can be reintroduced. One study suggests that adding omega-3 fatty acids to an elemental diet may boost its nutritional content and make it more likely that people with Crohn's disease will stick with it. Elemental diets should only be undertaking under the supervision of a physician.
Vitamins and Minerals
Because of decreased appetite, malabsorption, chronic diarrhea, side effects of medication, and surgical removal of parts of the intestine, many people with Crohn's disease don't get enough of some vitamins and minerals. In particular, people with Crohn's disease may lack adequate vitamin D, B12, and K, plus folic acid, calcium, and zinc. Your doctor may recommend that you take a multivitamin daily.
Zinc (25 mg), folic acid (800 mcg), vitamin B12 (800 mcg) -- The body uses these vitamins and minerals to repair cells in the intestine. In addition, drugs such as sulfasalazine and methotrexate may cause levels of folic acid in the body to drop, so that you need a supplement. Getting too much zinc can be immunosuppressive, folic acid in high doses over long periods of time has had some controversial reports associating it with certain illnesses. Speak with your doctor to determine the proper type and level of supplementation for your individual case.
Vitamin D (1,000 IU per day) -- The body needs vitamin D to maintain strong bones. People with Crohn's disease, especially those who take corticosteroids, often have low levels of vitamin D and are at risk for osteoporosis.
Calcium (1,000 - 1,200 mg per day) -- Calcium is also needed for strong bones. Ask your doctor if you need a calcium supplement.
Omega-3 fatty acids, such as those found in fish oil (2.7 g per day) -- These fats may help fight inflammation and reduce the chances of recurrence, but studies have been mixed. The study with the most positive results used a special type of fish oil – "enteric coated free fatty acid form" – that is not sold commercially. Some researchers suggest that measuring the blood levels of different types of fatty acids may help determine if fish oil would be useful. Do not take high doses of a fish oil supplement if you take blood-thinning medication.
Probiotics, especially Saccharomyces boulardi (250 mg 3 times per day to 500 mg 4 times per day) -- One small study indicated that this type of "friendly" bacteria helped people with Crohn's disease reduce the incidence of diarrhea. However, other studies have shown mixed results. People with allergies to yeast should avoid Saccharomyces boulardi. People with very weak immune system should check with their doctor before using probiotics.
N-acetyl glucosamine (NAG) -- Preliminary research suggests that N-acetyl glucosamine supplements or enemas may improve symptoms of inflammatory bowel disease, but more studies are needed to determine whether glucosamine would have any effect on Crohn's disease. There is some concern that NAG may raise blood sugar in patients with diabetes and may worsen asthma symptoms. NAG may interact with blood-thinning medications, such as warfarin (Coumadin) and certain cancer drugs.
Glutamine (400 mg 4 times per day) -- Glutamine is an amino acid found in the body that that helps the intestine function properly. While there is no evidence that glutamine specifically helps reduce symptoms of Crohn's disease, it may be good for overall intestinal health. It is best to take glutamine on an empty stomach. Do not take glutamine is you are diabetic or have seizures, suffer from bouts of mania, severe liver disease with difficulty thinking or confusion, or if you are sensitive to monosodium glutamate (MSG).
Because of the presence of inflammation and the nature of the disease, Crohn's disease should not be treated with herbs alone. However, herbs may be a useful complement to traditional medical treatment. Herbs can trigger side effects and interact with other herbs, supplements, or medications. For these reasons, you should take herbs with care, under the supervision of a health care provider.
The evidence for using herbs to treat Crohn's disease is mostly lacking. Herbs that have been used traditionally to treat inflammation within the digestive tract include:
- Slippery elm (Ulmus fulva) is a demulcent (a substance that protects irritated tissues and promotes their healing). Take 60 - 320 mg per day. One tsp. powder may be mixed with water and drunk 3 - 4 times a day. Take slippery elm at least one hour after taking other medications.
- Marshmallow (Althaea officinalis) is a demulcent and emollient (a substance that soothes mucous membranes). Drink one cup of tea 3 times per day. To make tea, steep 2 - 5 g of dried leaf or 5 g dried root in one cup boiling water. Strain and cool. Avoid marshmallow if you have diabetes. Marshmallow may interact with lithium. It may also interfere with drugs taken by mouth. Take Marshmallow at least one hour after taking oral medications.
- Curcumin or turmeric (Curcuma longa, 1 - 2 g per day) shows anti-inflammatory properties in test tubes. One small study found that people with inflammatory bowel disease who took curcumin reduced their symptoms and their need for medications. More research is needed. Curcumin may make gallbladder illnesses worse and may interact with blood-thinning medications.
- Cat's claw (Uncaria tomentosa, 250 mg per day) may help fight inflammation. Cat's claw may make leukemia, as well as autoimmune disorders, worse, and may worsen low blood pressure.
- Boswellia (Boswellia serrata, 1,200 mg 3 times per day for up to 8 weeks) has anti-inflammatory properties, and a few small studies suggest that it may help treat Crohn's disease. More research is needed to be sure. Boswellia may interact with other drugs and supplements, so talk to your doctor before taking it.
Although few studies have examined the effectiveness of specific homeopathic therapies, professional homeopaths may consider the following remedies for the treatment of Crohn's disease symptoms (such as diarrhea) based on their knowledge and experience. Before prescribing a remedy, homeopaths take into account a person's constitutional type -- your physical, emotional, and psychological makeup. An experienced homeopath assesses all of these factors when determining the most appropriate treatment for each person.
- Mercurius -- for foul-smelling diarrhea that may have streaks of blood accompanied by a sensation of incomplete emptying. This remedy is most appropriate for individuals who tend to feel exhausted following bowel movements, experience fluctuations in body temperature, perspire frequently, and have a thirst for cold fluids.
- Podophyllum -- for explosive, gushing, painless diarrhea that worsens after eating or drinking. Exhaustion often follows bowel movements. The individuals for whom this remedy is appropriate may experience painful cramps in the lower legs and feet.
- Veratrum album -- for profuse, watery diarrhea accompanied by stomach cramps, bloated abdomen, vomiting, exhaustion, and chills. The diarrhea tends to worsen as a result of eating fruit. The individual for whom this therapy is appropriate tends to crave cold liquids.
Acupuncture has long been used in Traditional Chinese Medicine to treat inflammatory bowel disease. One study in Germany found that acupuncture and moxibustion were effective specifically for treating Crohn's disease. Acupuncturists treat people with inflammatory bowel disease based on an individualized assessment of the excesses and deficiencies of qi located in various meridians. Moxibustion (a technique in which the herb mugwort is burned over specific acupuncture points) is sometimes used because it is thought by some to reach deeper into the body than using needles alone.
