Summary
Highlights
Ulcerative colitis is an inflammatory bowel disease causing inflammation and ulcers in the large intestine and rectum. It affects about a million Americans and while there's no cure, treatment can help manage symptoms and improve quality of life. The exact cause is unknown, but genetics, immune responses, and ethnicity may play a role. Diet and stress can exacerbate symptoms.
Symptoms vary based on severity and location, including diarrhea, fever, fatigue, anemia, weight loss, abdominal pain, and rectal bleeding. Complications can include dehydration, perforated colon, bone loss, inflammation, increased risk of blood clots, and colon cancer.
Diagnosis involves medical history review, blood tests, stool studies, colonoscopy or flexible sigmoidoscopy, and imaging like abdominal x-rays or MRI/CT scans to rule out other causes and assess the extent of inflammation. A biopsy is the only way to definitively diagnose the condition.
Treatment aims to alleviate symptoms and achieve remission using anti-inflammatory drugs, immune system suppressants, biologics, and symptom management medications. Surgery to remove damaged tissue or the entire colon may be necessary in severe cases. Side effects should be discussed with a doctor.
Managing triggers through a food diary, limiting dairy, eating small meals, staying hydrated, and avoiding caffeine, alcohol, and carbonation helps. Mental health is crucial; stress management techniques, therapy, and support groups can provide additional support. Advances in research continue to improve understanding and treatment.
