Introduction

For patients with mild to moderate ulcerative colitis, if effective medication treatments such as corticosteroids and aminosalicylic acid preparations are promptly administered and medical advice is strictly followed, including adjustments to diet and avoidance of irritating foods, symptoms of rectal bleeding can generally improve significantly within 2 weeks. Complete recovery may take approximately 1 month.

The rectal bleeding caused by ulcerative colitis usually improves within 1-3 months, although the specific duration may vary. If physical discomfort occurs, it is recommended to seek medical attention at a hospital promptly and follow the doctor's instructions for treatment.

For patients with mild to moderate ulcerative colitis, if effective medication treatment (such as corticosteroids, aminosalicylic acid preparations) is administered promptly and medical advice is strictly followed, along with adjustments to diet and avoidance of irritating foods, symptoms of rectal bleeding can generally improve significantly within 2 weeks. Complete recovery may take about one month, depending on the severity of inflammation and individual physical condition.

If the condition is severe, accompanied by symptoms such as fever and mucopurulent bloody stools, the recovery process will be relatively slower, potentially requiring 2-3 months. The specific duration of medication use and its effectiveness must be determined according to the doctor's advice and the patient's specific condition. In necessary cases, such as when medication proves ineffective or the condition continues to worsen, surgical treatment might be considered, including procedures like proctectomy, ileal pouch-anal anastomosis, or colectomy.

Patients should pay attention to their diet in daily life, avoid consuming spicy or irritating foods, and maintain good dietary hygiene. It is also important to maintain healthy lifestyle habits, such as chewing food thoroughly, eating slowly, and having frequent small meals.

Can a colonoscopy detect colorectal cancer?

In general, colonoscopy can detect colorectal cancer. Before undergoing a colonoscopy, you should follow your doctor's instructions to complete bowel preparation, such as taking laxatives and adjusting your diet, to ensure no fecal residue remains in the intestine and to avoid affecting the examination results. Mild bloating or abdominal pain after the procedure is usually normal and can be relieved by passing gas. However, if severe abdominal pain, rectal bleeding, or other abnormalities occur, medical attention should be sought promptly.

Whether colorectal tumors can be cured depends on the nature of the tumor, the stage of malignant tumors, and the timing of treatment. Benign tumors can mostly be completely cured with standardized treatment. Early-stage malignant colorectal tumors also have a favorable prognosis with active intervention, whereas treatment becomes more challenging in intermediate and advanced stages. When symptoms such as rectal bleeding, changes in bowel habits, or abdominal pain occur, timely medical evaluation via colonoscopy is recommended to determine the nature and stage of the tumor.
