During a colonoscopy, the doctor can also take small tissue samples (biopsies) and remove polyps — small growths, some of which can turn into cancer over time if left. This is one reason colonoscopy is used for bowel cancer screening.
At Tirtham Surgical Hospital, Science City Road, Sola, Ahmedabad, lower GI endoscopy is one of the endoscopic procedures listed by the hospital, and the hospital has an endoscopic setup. This page explains the types of lower GI endoscopy, when it is needed, bowel preparation, what happens, recovery and risks.
Types of Lower GI Endoscopy
| Test | What is examined | Points to note |
| Colonoscopy | The rectum and the whole colon, and sometimes the last part of the small bowel | Needs full bowel preparation; usually done with sedation; the complete examination used for screening and most symptoms |
| Flexible sigmoidoscopy | The rectum and the lower part of the colon | Usually needs only an enema; often done without sedation; shorter but examines only part of the bowel |
| Proctoscopy | The anal canal and lower rectum | A short examination in the clinic, often used for piles and fissures |
What Lower GI Endoscopy Can Find and Treat
| It can help diagnose | Treatments that may be done during the procedure, when needed |
| Polyps | Removal of polyps (polypectomy) |
| Bowel cancer, including at an early stage | Biopsies to confirm a diagnosis |
| Inflammatory bowel disease (ulcerative colitis and Crohn's disease) | Biopsies to assess inflammation |
| Diverticular disease | Stopping bleeding from a bleeding point |
| The source of bleeding from the back passage or unexplained anaemia | Marking (tattooing) an area so it can be found during later surgery |
| Narrowing (stricture) of the bowel | Stretching (dilatation) of some narrowings |
Lower GI endoscopy can also show that the bowel lining looks normal, which helps rule out a serious cause of the symptoms.

When a Colonoscopy May Be Needed
| Symptom or situation | Why it matters |
| Bleeding from the back passage, or blood in the stool | To find the cause |
| A change in bowel habit lasting more than a few weeks | A warning sign that needs investigation |
| Unexplained anaemia or weight loss | Can point to a bowel cause |
| Long-standing diarrhoea | To look for inflammation or other causes |
| Screening for bowel cancer | Many international guidelines advise bowel cancer screening (by stool test or colonoscopy) from about 45–50 years for people at average risk; your doctor can advise whether it applies to you |
| A family history of bowel cancer or polyps | Screening may be advised earlier |
| A previous polyp, bowel cancer or inflammatory bowel disease | Follow-up (surveillance) colonoscopy at advised intervals |
Bleeding Is Not Always Piles
Bleeding from the back passage is often caused by piles or a fissure, but it can also come from a polyp, inflammation or bowel cancer. It should not be assumed to be piles without a check by a doctor, especially if you are over 40, if the bleeding is new, or if it comes with a change in bowel habit, weight loss or dark blood mixed with the stool.

Colonoscopy Procedure in Ahmedabad: Step by Step
The bowel must be completely clean for the doctor to see the lining clearly. Poor preparation can mean that polyps are missed or the test has to be repeated.
| Stage | What happens |
| A few days before | A low-fibre diet, as advised; iron tablets may need to be stopped; tell the team about blood thinners and diabetes medicines |
| The day before and the day of the test | Clear liquids only, and the prescribed bowel preparation solution, often split into two doses; expect frequent loose motions; drink plenty of clear fluids to avoid dehydration; clear liquids are usually stopped about 2 hours before the test, as advised |
| During | Sedation through a vein; you lie on your side; the colonoscope is passed through the back passage, and air or carbon dioxide is used to open the bowel; the test usually takes about 20–45 minutes |
| After | You rest until the sedation wears off; bloating and cramps settle as the gas passes; the findings are explained, and biopsy and polyp results follow later |
After Sedation
After sedation, do not drive, operate machinery, sign important documents or drink alcohol for the rest of the day. Someone should take you home. Most people return to normal activities the next day. If a polyp was removed, specific advice is given on activity, medicines and warning signs.
Risks and Possible Complications
Colonoscopy is generally safe, but like any procedure it has risks. The doctor explains these before taking consent.
- Bloating and cramps for a short time
- Dehydration or salt imbalance from the bowel preparation, especially in older people or those with kidney or heart disease
- Reaction to sedation, such as breathing or heart rhythm problems — uncommon
- Bleeding, mainly after polyp removal; usually within two weeks, occasionally later
- A tear (perforation) of the bowel — rare, more likely after polyp removal or stretching, and may need surgery
- Incomplete examination, because of poor preparation or a difficult bowel, needing a repeat test or another test such as CT colonography
- A polyp or other abnormality being missed, which is why preparation and follow-up matter
When to Contact the Hospital After the Test
- Severe or increasing abdominal pain, or a swollen, hard abdomen
- Fever or chills
- More than a small amount of bleeding from the back passage
- Dizziness or fainting

Lower GI Endoscopy Doctor in Ahmedabad
A colonoscopy is performed by a gastroenterologist or a surgeon trained in endoscopy. A lower GI endoscopy doctor in Ahmedabad usually works with other doctors before and after the test:
| Doctor | Role in lower GI endoscopy |
| Family physician | First assessment of bowel symptoms; refers for colonoscopy or arranges a stool test for screening |
| Gastroenterologist or surgeon trained in endoscopy | Decides whether the test is needed, performs the colonoscopy, takes biopsies and removes polyps when suitable |
| Anaesthetist | Gives or supervises sedation at some centres, especially for patients with heart or lung disease |
| Pathologist | Examines biopsies and removed polyps under a microscope |
| General or colorectal surgeon | Plans surgery when a cancer, a large polyp or a narrowing cannot be treated through the endoscope |
Questions worth asking before the test:
- Do I need a full colonoscopy, or would a sigmoidoscopy be enough?
- How should I take the bowel preparation, and what can I eat or drink?
- Should I stop blood thinners, diabetes medicines or iron tablets, and for how long?
- Will I be given sedation, and who will take me home?
- If a polyp is found, will it be removed during the same test?
- When will the biopsy or polyp results be ready, and when is the next colonoscopy due?
