Managed by our team of male and female colorectal specialists, Colorectal Practice delivers comprehensive care for all gastrointestinal (GI) disorders and colorectal conditions.
We provide accurate diagnoses and timely treatments, specialising in advanced endoscopy such as colonoscopy and gastroscopy. With same-day appointments available at our conveniently located clinics in Mount Elizabeth Orchard, Mount Elizabeth Novena, Gleneagles and Mount Alvernia, care is never far away.
It is time to consult a specialist if you are experiencing any of the following symptoms:
This could indicate bleeding in your digestive tract, which may stem from conditions like haemorrhoids, ulcers, or more serious concerns such as colorectal cancer.
Chronic changes in bowel habits may signal underlying issues like irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), or even an obstruction.
Frequent or intense abdominal pain can result from various conditions, including food intolerances, infections, or gastrointestinal disorders that need medical evaluation.
Struggling to swallow food or liquids may point to problems in the oesophagus, such as gastroesophageal reflux disease (GERD), strictures, or, in rare cases, cancer.
While common, ongoing acid reflux could lead to complications like oesophagitis or Barrett’s oesophagus if left untreated.
Many patients reach out to us, worried that their gastrointestinal (GI) symptoms could be cancer. An endoscopy – in particular a colonoscopy – can effectively detect early or even pre-cancerous stages of colorectal cancer. Crucially, it can also rule out cancer and identify other benign GI causes, offering immediate peace of mind as you embark on a tailored treatment plan.
When GI conditions like ulcers, polyps, inflammation, or even cancer are detected sooner, it allows for timely intervention which can significantly improve outcomes, prevent disease progression, and alleviate symptoms. An early and accurate diagnosis also allows for less invasive treatments with fewer risks and faster recovery.
Diagnosis typically begins with a thorough medical history assessment and physical exam. Depending on your condition, we may recommend additional lab tests or imaging tests. An invaluable tool in diagnosis is endoscopy. This minimally invasive procedure gives our specialists a clear view of your upper or lower digestive tract, allowing them to detect and address potential issues before they escalate.
Endoscopy is a safe, quick, and highly effective procedure for diagnosing and treating GI conditions. It involves a thin, flexible tube with a camera that provides real-time visuals of the digestive system, such as the stomach (gastroscopy) or colon (colonoscopy).
An endoscopy can also obtain biopsies or even perform certain treatments on the spot, offering both diagnostic and therapeutic benefits. With its versatility and effectiveness, endoscopy is a trusted tool for addressing gastrointestinal concerns efficiently and comfortably.
