How Colitis is Diagnosed: Understanding the Symptoms and Diagnostic Procedures

Colitis, a condition characterized by inflammation of the colon, can present a wide range of symptoms that can range from mild discomfort to severe pain. Proper diagnosis and early intervention are crucial for managing the condition effectively. Understanding the symptoms and diagnostic procedures can help in identifying the condition and initiating appropriate treatment.

Symptoms of Colitis

The initial symptoms of colitis often include stomach pain, which is frequently aggravated by eating. Other common symptoms include nausea, weight loss, and diarrhoea. Stools may contain white mucus or blood, the presence of which can indicate a more severe form of the condition.

Other symptoms that may be experienced include:

Urgency to defecate Inability to defecate despite the urgency Weight loss Fatigue Rectal pain Rectal bleeding, often seen as a small amount of blood mixed with the stool

Diagnosis of Colitis

To diagnose colitis accurately, healthcare professionals often rely on a combination of physical examinations, medical history, and diagnostic tests.

Physical Examination and Medical History

The first step in diagnosing colitis involves a thorough physical examination and a detailed medical history. During the examination, the doctor will assess general symptoms and may perform a digital rectal exam to check for any abnormalities. The medical history will provide valuable insights into the patient's symptoms, their duration, and any previous episodes of similar symptoms.

Diagnostic Tests

Several diagnostic tests are commonly used to confirm the diagnosis of colitis. Some of the most common tests include:

Colonoscopy

One of the primary methods used to diagnose colitis is a colonoscopy. This procedure involves inserting a flexible tube with a camera into the rectum to visualize the colon. The colonoscopy not only allows for a direct visual examination but also enables the retrieval of tissue samples for further analysis. While colonoscopy can be uncomfortable, it is generally considered more accurate than other diagnostic methods for confirming the presence of colitis.

Sigmoidoscopy

Similar to a colonoscopy, a sigmoidoscopy is a diagnostic test that allows for the visualization of the lower part of the colon (sigmoid colon). A sigmoidoscopy can be less invasive than a full colonoscopy, making it a useful tool for diagnosing colitis in the lower colon. However, it may not provide a complete picture of the entire colon.

Biopsy

A biopsy involves taking tissue samples from the colon during a colonoscopy or sigmoidoscopy. These samples are then analyzed in a laboratory to determine the presence of inflammation and rule out other conditions with similar symptoms.

Endoscopy

Endoscopy is another diagnostic technique that may be used, especially in cases where gastrointestinal symptoms are severe. This procedure involves the use of an endoscope to visualize the digestive tract and can help in identifying areas of inflammation and other abnormalities.

Imaging Studies

Although less common, imaging studies such as CT scans or MRI can be used to assess the extent of colon inflammation and rule out other conditions. These tests provide detailed images of the digestive tract and can help in diagnosing and staging the condition.

A Personal Story

The experience of diagnosis is often a shared struggle. Consider the case of a young Black American female, who at the age of 22, experienced urgent bathroom trips, mixed blood in her stool, and sought medical help from her mother who worked in her doctor's office. Following these alarming symptoms, a gastroenterologist recommended a sigmoidoscopy after which she was diagnosed with Ulcerative Colitis (UC). At the time of diagnosis, she was 110 lbs, 5’5, diligently managing the symptoms, and working towards the end of her college years.

Hers is a story of early recognition and intervention, underscoring the importance of timely medical attention and seeking help when symptoms are noticed.
