It is not clear what causes Crohns disease. Genes, the environment, and problems with the immune system may all play a role.
The risk of Crohns disease is higher in those with:
- Family members with Crohns
- Tobacco use disorder
- Low activity levels
- Stress-related disorders
- Regular use of medicine, such as antibiotics and nonsteroidal anti-inflammatory drugs
- Infections of digestive system, such as salmonella or campylobacter gastroenteritis
Flare ups of Crohns disease may cause:
- Belly cramps and pain
- Rectal bleeding
- Weight loss
- Weakness and lack of energy
- Mouth sores
- Sores in the anal area
The doctor will ask about your symptoms and past health. A physical exam will be done. Blood and stool tests will be done to look for any problems and rule out other issues. Scopes can be done to look for areas of inflammation. This can be done with:
- Upper endoscopy
A sample of intestine may be removed with a scope for biopsy . The sample will be sent to a lab for testing.
Special dyes may also be used to help highlight the intestines in other image tests such as:
- Upper gastrointestinal series
- Lower gastrointestinal series
- CT scan
- MRI scan
There is no cure. Flare up treatment will manage symptoms and try to avoid other problems from starting. Treatment may also be used during remission to prevent flare ups. The treatment plan can vary. Some step may include:
Medicines to help:
- Reduce inflammation—may be short term for flare ups
- Lower immune system response—may be long term medicines to help prevent flare up
- Manage pain, diarrhea or nausea
- Bowel rest for severe bout of inflammation—no food, only drinking nutritious drinks for a time.
- Nutrition support—vitamins or supplements to improve nutrition during flare up.
- Surgery—to removed damaged areas, improve severe symptoms, or treat complications of Crohns.
Other treatment may be needed to treat other problems caused by Crohns.
