Rectal bleeding frequently occurring after consuming spicy food suggests a high likelihood of colitis, though hemorrhoids or anal fissures cannot be ruled out. The patient should first adjust their diet by avoiding spicy and irritating foods. If symptoms are severe or persist without improvement, prompt medical evaluation at a hospital is necessary, including colonoscopy to determine the underlying cause and guide targeted treatment—this will aid in recovery. Washing the perianal area with warm saline solution may help alleviate symptoms.
