Crohn's Disease
Crohn's Disease is an intestinal disorder characterized by inflammation of the digestive tract. Crohn's disease is characterized by ulceration of the intestines and affects the GI tract. The exact cause for Crohn's disease is unknown thought it is suspected to be due to bacterial infection. Crohn’s disease is an inflammatory bowel disease that differs from ulcerative colitis in that the inflammation and ulceration is noticed in all the layers of the intestines. It is noticed that people of Jewish descent are at increased risk for developing Crohn's disease. The symptoms are similar to irritable bowel syndrome.
20% cases of Crohn's disease are heriditary in nature. Symptoms of Crohn's disease are rectal bleeing and diarrhea. There is abdominal pain and weight loss. Nutritional deficiencies are noticed with patients suffering from Crohn's disease caused due to poor absorption. There may be arthritis, skin problems or gallstones.
Blood tests are done to check for presence of certain antibodies that may help diagnose Crohn's disease. A colonoscopy can aid the doctor in examining the lining of the intestines and checking the extent of inflammation. A small sample may also be taken for biopsy. CT scans and small bowel x-rays can help in identifying the areas of inflammation within the intestines. Anti-inflammatory drugs are prescribed to control inflammation. Corticosteroids such as Prednisone are used in treating Crohn's disease. Antibiotics are used to treat bacterial overgrowth in the small intestine. Surgery is often resorted to in most cases of Crohn's disease. A part of the intestine is removed or any blockage is removed. But Crohn's disease is likely to resurface after some years of surgery.
Ulcerative Colitis
Ulcerative colitis is an condition of inflammation or ulcers in the lining of the large intestine, rectum and colon. Rarely is the small intestine affected by ulcerative colitis. Ulcerative colitis is also referred to as proctitis. While this condition can affect anyone, it is noticed more often in the US, England, Eastern Europe and persons of Jewish ancestry. Ulcerative colitis is a chronic condition that is often noticed to run in families. The symptoms of Ulcerative colitis are similar to Crohn's disease. But this disease tends to affect the small intestine or the mouth, esophagus, appendix or duodenum. Ulcerative colitis and Crohn's disease are both inflammatory bowel diseases. Typical symptoms of Ulcerative colitis include fatigue, nausea and severe abdominal cramps. Rectal bleeding and diarrhea are noticed with persons suffering from Ulcerative colitis, though the intensity depends on the inflammation. There is loss of appetite and weight loss. The symptoms may tend to recur at regular intervals or when eating highly seasoned food or raw fruits and vegetables. Other conditions such as hepatitis, osteoporosis, anemia and arthritis are sometimes triggered by Ulcerative colitis.
Ulcerative colitis has been traced to abnormal disorder of the immune system of the intestine. Consequently the immune system triggers off an inflammation of the intestinal tissues. Often a diet high in fat and refined foods may be responsible for ulcerative colitis. Symptoms of ulcerative colitis tend to come in spurts, with periods of acute illness followed by periods of remission. If left untreated, persons suffering from ulcerative colitis carry significant risk of carcinoma. Treatment for ulcerative colitis is based on the seriousness of the condition. While medication can help in most cases, surgery is resorted to for severe inflamation and life-threatening condition. Medications cannot cure ulcerative colitis but they can help in maintaining periods of remission. The patient can enjoy a better quality of life. Anti-inflammatory and immunomodulators are prescribed for patients of ulcerative colitis to reduce inflammation.
Gastroenterologist
Physicians who specialize in the diagnosis and treatment of the digestive system or gastrointestinal tract are gastroenterologists. When they specialize to treat children in the same area, they are termed as pediatric gastroenterologist. They treat conditions such hepatitis, colon or rectal cancer, ulcerative colitis and Crohn's disease. A gastroenterologist must complete four years of degree, four years of medical school, three years residency in internal medicines and later specialize in gastroenterology for a period of two to three years. Certification from a recognized board is necessary.
Role of gastroenterologist
Diagnose and offer medical treatment for any kind of disorder in the gastrointestinal tract.
Order for blood tests, x-rays, endoscope checks of the stomach called gastroscopy or for the large intestine called colonoscopy depending on the patient's illness.
Assist a surgeon in exactly locating the area of problem that needs treatment in the gastrointestinal section.
They follow up digestive system disorders that include esophagus, small and large intestine, stomach, pancreas and the liver. They also follow up on symptoms of heartburn, indigestion, ulcers etc following an operation.
Modern techniques and gastroenterologist
Use of ultra high frequency in endosonography gives better understanding of any lesions formed.
Measuring of myoelectric and contractile activity in the gastrointestinal tract, esophageal and anal manometry to understand constipation, nausea, abdominal pain etc better in any patient.
Electrogastrography and few other modern techniques have made it easier to understand the esophageal transit in patients easier.
