Doctors Near You for Hematochezia in Porto alegre

Hematochezia refers to the passage of fresh red blood from the rectum, typically seen in the stool or as a separate blood discharge. This condition is a concerning symptom and often indicates bleeding in the lower gastrointestinal tract, although it can sometimes originate from higher up in the digestive system. The causes of hematochezia are diverse. One common cause is hemorrhoids, which are swollen blood vessels in the rectum or anus that can bleed during bowel movements. Anal fissures, which are small tears in the lining of the anus, can also lead to bright red bleeding. Gastrointestinal conditions such as diverticulosis, where small pouches form in the colon and can become inflamed or bleed, may result in hematochezia. Inflammatory bowel diseases like ulcerative colitis and Crohn's disease can cause rectal bleeding due to inflammation and ulceration of the bowel lining. Colorectal polyps and colorectal cancer can also present with hematochezia, as these conditions may cause bleeding either through direct tumor invasion or ulceration. Additionally, gastrointestinal infections or angiodysplasia, which involves abnormal blood vessels in the colon, can contribute to rectal bleeding. Treatment for hematochezia depends on the underlying cause. For hemorrhoids and anal fissures, management often involves dietary changes to ensure softer stools, topical treatments, and sometimes surgical interventions for severe cases. For conditions like diverticulosis or inflammatory bowel diseases, treatment may include medications such as antibiotics, anti-inflammatory drugs, or immunosuppressants, as well as dietary modifications. Colorectal cancer or polyps may require more extensive interventions, including endoscopic removal, surgical resection, or chemotherapy, depending on the stage and extent of the disease. Diagnostic procedures such as colonoscopy or sigmoidoscopy are crucial in identifying the source of bleeding and guiding treatment. In all cases, addressing the root cause of the bleeding is essential to manage symptoms effectively and prevent complications. If hematochezia is severe, persistent, or accompanied by symptoms like dizziness, weakness, or significant changes in bowel habits, prompt medical evaluation is necessary to ensure proper diagnosis and treatment.
