Definition and Types:

Inflammatory Bowel Disease (IBD) is an umbrella term for chronic inflammatory conditions of the digestive tract, primarily including Ulcerative Colitis and Crohn's Disease.
Inflammation Location:

Ulcerative Colitis: Causes continuous inflammation starting from the rectum and extending into the colon. It affects only the inner lining of the colon.
Crohn's Disease: Can cause patchy areas of inflammation (skip lesions) anywhere in the gastrointestinal tract from the mouth to the anus and affects the entire thickness of the bowel wall (transmural).
Common Symptoms:

Ulcerative Colitis: Hallmarked by chronic bloody diarrhea and lower left abdominal pain due to inflammation of the rectum and sigmoid colon.
Crohn's Disease: Frequently presents with lower right abdominal pain, nonbloody diarrhea in early stages, and weight loss due to inflammation often involving the terminal ileum.
LongTerm Risks:

Ulcerative Colitis: Increased risk of colorectal cancer and potential for toxic megacolon, a severe enlargement of the colon. It can also involve other organs like the liver, causing primary sclerosing cholangitis.
Crohn's Disease: Higher likelihood of complications like fistulas (abnormal connections between intestines and other organs), abscesses, and strictures leading to bowel obstruction.
Extraintestinal Manifestations:

Both conditions can affect other parts of the body due to their autoimmune nature, including the skin, joints, and liver.
Imaging and Diagnostic Features:

Ulcerative Colitis: Diagnosed by continuous inflammation seen on endoscopy starting from the rectum.
Crohn's Disease: Identified by patchy inflammation, deep ulcers, cobblestone appearance on colonoscopy, and granulomas on biopsy.
Dietary Recommendations:

Both diseases benefit from a lowresidue diet during active phases, including refined grains, cooked vegetables without skins, fruits without skins or seeds, wellcooked meats, and dairy products if tolerated.
FirstLine Treatments:

Ulcerative Colitis: Typically managed with aminosalicylates like mesalamine or sulfasalazine, with corticosteroids used during acute flareups.
Crohn's Disease: Often treated with corticosteroids like budesonide and sometimes aminosalicylates, though they are less effective than in ulcerative colitis.
Supplements and Nutrition:

Patients with both conditions may require supplements such as calcium, vitamin D, and specific vitamins like B12 (especially after ileum resection in Crohn's disease) to address deficiencies caused by malabsorption and chronic inflammation.
Management of Complications:

Ulcerative Colitis: Regular cancer screening is crucial due to the increased risk of colorectal cancer. Most patients can achieve longterm remission with treatment.
Crohn's Disease: Management often involves multiple surgeries over a lifetime to address complications like strictures, abscesses, and fistulas.
