What Is Crohn's Disease?
Crohn's disease is a chronic inflammatory bowel disease that can affect any part of the digestive tract, from the mouth to the anus. It most often involves the end of the small intestine (the ileum) and the colon, and the inflammation can extend through the full thickness of the bowel wall, which is why it can lead to narrowing, fistulas or abscesses.
The course varies widely. Some people have mild or intermittent symptoms; others have periods of more active disease. Because Crohn's disease is long term, ongoing care with a gastroenterologist is an important part of managing it.
What Are the Symptoms of Crohn's Disease?
Symptoms depend on which part of the digestive tract is affected and how active the inflammation is. Some people also have symptoms outside the gut, such as joint pain, skin rashes, eye inflammation or mouth sores.
Not everyone with these symptoms has Crohn's disease. Many digestive conditions cause similar symptoms, so a careful evaluation is important.
When to seek emergency care
Seek emergency care for severe abdominal pain, a swollen and tender abdomen, persistent vomiting, high fever, heavy rectal bleeding, or signs of dehydration such as dizziness and very little urine.
Common symptoms of Crohn's disease
- Persistent or recurring diarrhea
- Abdominal pain or cramping, often in the lower right abdomen
- Unexplained weight loss or reduced appetite
- Fatigue
- Blood in the stool, in some patients
- Urgent bowel movements
- Fever during flares
- Pain or drainage near the anus
These symptoms have many possible causes and should be evaluated by a qualified medical professional.
When Should You See a Crohn's Disease Specialist?
See a gastroenterologist for chronic diarrhea, ongoing abdominal pain, blood in the stool, unexplained weight loss or persistent fatigue with digestive symptoms. If you already have a Crohn's diagnosis, specialist care helps when symptoms change, flares return, treatment is not working, or you want a second look at your plan.
Crohn's disease is not caused by one food or by stress, but certain foods and stressful periods can worsen symptoms for some people. Smoking is a known risk factor that can make Crohn's disease worse.

United Gastroenterology Associates welcomes new patients seeking evaluation for Crohn's disease, ulcerative colitis, chronic diarrhea, abdominal pain, colonoscopy and other digestive concerns.
How Is Crohn's Disease Diagnosed?
There is no single test for Crohn’s disease. Diagnosis combines your history and examination with tests chosen for your symptoms and the suspected location of disease.
History and Examination
Your symptoms, their timing, weight changes, family history, prior tests and medications are reviewed in detail.
Blood and Stool Tests
Blood tests check for inflammation, anemia and nutrition; stool tests such as calprotectin help detect intestinal inflammation and rule out infection.
Colonoscopy With Biopsies
Examines the colon and the end of the small intestine and takes tissue samples to confirm the diagnosis.
Imaging and Other Tests
CT or MR enterography, capsule endoscopy or upper endoscopy may be used to evaluate the small intestine and complications.
How Is Crohn's Disease Treated?
Treatment is individualized based on where the inflammation is, how severe it is, your previous treatments and other health conditions. The goals are to control inflammation, relieve symptoms, heal the bowel and prevent complications. Options may include:
Corticosteroids
Used for short periods to calm a flare, not for long-term maintenance.
Immunomodulators
Medicines such as thiopurines or methotrexate that reduce immune activity, sometimes combined with other therapies.
Biologic and Targeted Therapies
Advanced medicines that block specific inflammatory pathways and are used for moderate to severe disease.
Nutrition Support
Attention to nutrition, vitamin and iron levels, and, for some patients, specialized nutritional therapy.
Surgery When Needed
For strictures, fistulas, abscesses or disease that does not respond to medicine, in coordination with a surgeon.
Ongoing Monitoring
Regular follow-up, lab work and colonoscopy as needed to track inflammation, adjust treatment and screen for complications.
Results vary from person to person, and treatment cannot guarantee remission. Do not stop or change prescribed medicine without talking with your gastroenterologist.
Possible Complications of Crohn's Disease
Not everyone develops complications, but long-standing inflammation can cause problems that are easier to manage when found early.
Strictures and Blockage
Scarring can narrow the intestine and cause cramping, bloating and, in some cases, blockage.
Fistulas and Abscesses
Abnormal tunnels or infected pockets can form, including around the anus.
Nutritional Deficiencies
Inflammation and reduced absorption can lower iron, vitamin B12, vitamin D and other nutrients.
Colon Cancer Risk
Long-standing Crohn’s disease involving the colon increases colorectal cancer risk, so surveillance colonoscopy is recommended.
Crohn's Disease and Colonoscopy
Colonoscopy helps diagnose Crohn's disease affecting the colon and the end of the small intestine, judge how active and extensive it is, take biopsies, investigate bleeding or chronic diarrhea, and monitor some patients over time, including surveillance for colorectal cancer. The need and timing of colonoscopy are individualized.
Crohn's Disease and Diet
No single diet suits everyone with Crohn's disease. Food tolerance and nutritional needs depend on symptoms, disease activity and where the inflammation is. Your care team may help you identify trigger foods, maintain good nutrition and hydration, adjust what you eat during flares and decide whether nutritional support is needed.

Crohn's Disease: Frequently Asked Questions
Answers to common questions about Crohn's disease care in Katy and Cypress.
What type of doctor treats Crohn's disease?
A gastroenterologist diagnoses and manages Crohn's disease and other inflammatory bowel diseases, often working with surgeons and dietitians when needed.
Is Crohn's disease the same as IBS?
No. Crohn's disease causes inflammation and damage in the digestive tract and is a form of IBD. IBS causes symptoms without that inflammation.
Can Crohn's disease cause blood in the stool?
It can in some patients, but blood in the stool has many causes and should always be evaluated.
Is Crohn's disease curable?
Crohn's disease is a chronic condition. Treatment aims to control inflammation and symptoms, and many people have long periods of well-controlled disease, but outcomes vary and cannot be guaranteed.
How is Crohn's disease diagnosed?
Through a combination of history, blood and stool tests, colonoscopy with biopsies and, when needed, imaging of the small intestine.
Do I need regular colonoscopies with Crohn's disease?
Many patients do, to monitor inflammation and, when the colon is involved, to screen for colorectal cancer. Your gastroenterologist recommends the timing.
