Symptoms of Rectal Bleeding and Swelling - Surgery

More Info

When experiencing rectal bleeding and swelling around the anus, it is crucial to understand the potential causes and the appropriate steps to take. The symptoms you describe—sudden blood during bowel movements, swelling around the anus, and the sensation of something being present in the rectal area—can be indicative of several conditions, most commonly hemorrhoids, anal fissures, or even more serious issues such as rectal polyps or colorectal cancer.

Hemorrhoids are swollen veins in the lower rectum and anus that can cause bleeding, especially during bowel movements. They can be internal (inside the rectum) or external (under the skin around the anus). Symptoms often include bright red blood on toilet paper or in the toilet bowl, itching, and discomfort. Swelling may occur if the hemorrhoids become thrombosed (clotted), leading to significant pain and a feeling of fullness.

Anal fissures are small tears in the lining of the anus, often caused by passing hard stools. They can result in sharp pain during and after bowel movements, along with bleeding. The blood is typically bright red and may be seen on the stool or toilet paper.

Rectal polyps are growths on the lining of the rectum that can also cause bleeding. While many polyps are benign, some can develop into colorectal cancer over time. Symptoms may include rectal bleeding, changes in bowel habits, and abdominal discomfort.

Colorectal cancer is a more serious condition that can present with rectal bleeding, changes in bowel habits, weight loss, and abdominal pain. It is essential to consider this possibility, especially if you have risk factors such as a family history of colorectal cancer, age over 50, or other gastrointestinal symptoms.

Given your symptoms, it is advisable to seek medical attention promptly. You should consult a gastroenterologist or a general practitioner who can perform a thorough evaluation. This may include a physical examination, a digital rectal exam, and possibly further diagnostic tests such as a colonoscopy, which allows for direct visualization of the colon and rectum, and can help identify the cause of your symptoms.

When you visit the doctor, be prepared to provide a detailed history of your symptoms, including when they started, the nature of the bleeding (e.g., color, amount), any associated pain, and any changes in bowel habits. This information will help your healthcare provider make an accurate diagnosis.

In the meantime, avoid straining during bowel movements, maintain a high-fiber diet, and stay hydrated to help prevent constipation, which can exacerbate hemorrhoids and fissures. Over-the-counter treatments, such as topical creams for hemorrhoids, may provide temporary relief, but they do not replace the need for a medical evaluation.

In summary, rectal bleeding and swelling around the anus can be caused by various conditions, ranging from benign to serious. It is essential to seek medical advice to determine the underlying cause and receive appropriate treatment. Early intervention can lead to better outcomes, especially if a more serious condition is present.
