When to see a colorectal surgeon
Seek specialist assessment if symptoms persist or warning signs are present.
Many colorectal symptoms are treatable, but they should not be ignored. Early assessment can provide reassurance, identify the cause and guide treatment.
- Rectal bleeding
- Blood in the stool
- Persistent abdominal pain
- Unexplained weight loss
- Chronic constipation
- Persistent diarrhoea
- Anal pain or swelling
- Family history of colorectal cancer
- Positive screening tests
- Persistent changes in bowel habits
Colorectal cancer
Early detection significantly improves treatment outcomes.
Colorectal cancer is one of the most common cancers worldwide. It may develop from colon polyps over several years, which is why screening can play such an important role in prevention and early diagnosis.
Possible symptoms
Blood in the stool, unexplained weight loss, persistent abdominal pain, changes in bowel habits, fatigue and anaemia should be assessed.
Treatment planning
Treatment may include surgery, chemotherapy or radiation therapy depending on the stage and location of disease.
Multidisciplinary care
Dr Nathire works within a multidisciplinary team to provide comprehensive cancer care and coordinated treatment planning.
Screening matters
Regular screening can detect and remove polyps before cancer develops, and can identify cancer at an earlier stage.
Colonoscopy and screening
What is a colonoscopy?
A colonoscopy is the gold standard investigation for examining the inside of the colon and rectum. It allows direct visualisation of the bowel lining using a flexible camera and can identify polyps, inflammation, bleeding sources and colorectal cancer.
The procedure is usually performed under sedation. Patients are generally comfortable throughout and usually return home the same day.
Why screening is important
Screening can find polyps before they become cancerous and can detect colorectal cancer at an earlier stage, when treatment is often more effective.
- Early cancer detection
- Polyp removal
- Accurate diagnosis
- Prevention of colorectal cancer
- Assessment of bleeding, anaemia and bowel habit changes
Patient information
Common colorectal conditions explained.
Haemorrhoids
Swollen blood vessels in the anal canal that may cause bright red bleeding, itching, swelling, pain or prolapse. Many respond to fibre, medication or office procedures; surgery is reserved for advanced cases.
Anal fissures
A small tear in the lining of the anal canal that can cause sharp pain during bowel movements, bleeding and burning discomfort. Early treatment can prevent chronic symptoms.
Anal fistulas
An abnormal tunnel connecting the anal canal to the skin around the anus, often following infection or abscess. Treatment is usually surgical and aims to eliminate infection while preserving continence.
Diverticular disease
Small pouches develop in the wall of the colon and may cause abdominal pain, bloating or altered bowel habits. Complications can include diverticulitis, abscess, perforation or obstruction.
Crohn's disease
A chronic inflammatory bowel disease that can affect any part of the digestive tract. Medical and surgical treatment can help patients achieve long-term disease control.
Ulcerative colitis
A chronic inflammatory condition affecting the colon and rectum. Management may include medication, surveillance colonoscopy and surgery in selected cases.
Pelvic floor disorders
Conditions such as rectal prolapse, faecal incontinence and obstructed defecation. Treatment may include physiotherapy, lifestyle modification or surgery.
Patient information
Your first consultation may include a discussion of symptoms, medical history and treatment options. Please bring previous medical records, investigation results, a medication list and medical aid information.
