What is gastroenterology? 

Gastroenterology is the field of medicine that investigates, diagnoses and treats diseases and dysfunctions found in your digestive system. A doctor who specialises in this field is known as a gastroenterologist. 

What is the digestive system? 

Your digestive system is the collection of organs that help break food down so that it can be absorbed into the body. It works to remove the leftover waste products that cannot be used by the body by expelling them as solid waste (i.e. your stools).  

Your digestive system is incredibly complex, comprising many different parts and functions. A healthy digestive system is vital to the proper functioning and health of your body. 

Your gastrointestinal (GI) tract runs from mouth to anus and is made up of: 

  • Upper GI – your mouth, tongue, oesophagus, stomach and first part of the small intestine 
  • Lower GI (Colorectal) – the latter part of your small intestine, your large intestine (or colon), rectum, and anus 
  • HBP (hepato pancreato biliary) – your liver, pancreas, and gallbladder 

If a problem occurs in any of these parts of the digestive system, it can have a significant effect on your health, vitality and energy levels. Many problems in the digestive system will cause noticeable symptoms, such as pain in the abdomen, bloating or heartburn. 

At Shirley Oaks Hospital, our consultant gastroenterologists provide expert assessment, diagnosis, and treatment for a wide range of digestive system conditions and symptoms. They would be delighted to help you on your healthcare journey with us. 

 

Common concerns that affect your digestive system 

Patients who visit our gastroenterology team at Shirley Oaks Hospital often have certain symptoms that may suggest a problem somewhere within the digestive system.  

The most common symptoms we see are: 

  • Pain in the abdomen 
  • Bloating 
  • Indigestion 
  • Nausea and/or vomiting 
  • Blood in vomit 
  • Diarrhoea
  • Constipation 

Other altered bowel habits include:

  • Rectal bleeding – this may be visible or hidden (‘occult’) 
  • Acid reflux – where stomach acid passes up the throat and causes heartburn 
  • Jaundice (yellow discolouration of skin)

If you are experiencing any of these symptoms, or you have had an abnormal liver function test result, it is always sensible to see medical advice. While your symptoms may not be a cause for concern, proper assessment can help with your peace of mind. 

Our gastroenterology team are experts in this field, providing comprehensive investigation into your symptoms to find out what is causing them and what the best treatment would be for you. 

Due to the size and complexity of the digestive system, many conditions will often have overlapping symptoms. Our consultant gastroenterologists will use their expertise in the field to help narrow down the causes. 

Some of the common conditions that affect the healthy functioning of the digestive system include: 

  • Cancer – Oesophageal, bowel, liver, bile duct or pancreatic 
  • Inflammatory bowel disease (IBD) – This includes both Crohn’s disease and ulcerative colitis 
  • Indigestion (dyspepsia) 
  • Diverticulitis – Diverticula are small pouches that can develop in the lining of the intestine. If they become inflamed, it is known as diverticulitis 
  • Bowel polyps – Abnormal growths of tissues, often looking like small, raised bumps. While they are often harmless, they may become cancerous if left untreated over a number of years 
  • Gallstones – Small stones that may form in the gall bladder 
  • Liver abscess 
  • Gastroesophageal reflux disease (GERD/GORD) 
  • Fatty liver disease 
  • Peptic ulcer disease

Many of these conditions are more easily treated when they’re found at the earliest possible stage. 

At Shirley Oaks Hospital, we can offer you rapid access to comprehensive investigation from an expert. Getting an earlier assessment and diagnosis will mean you will be able to see the benefits of any treatment sooner.


 

What happens at a gastroenterology appointment at The Shirley Oak Hospital? 

When you first meet with one of our consultants, they ask you about your medical history and any symptoms.  

They may ask you questions during your appointment such as:

  • What symptoms do you have?
  • How long you’ve had these symptoms?
  • Have your symptoms have been getting more noticeable/severe over time?
  • Have any particular foods, drinks, or activities made your symptoms worse?
  • Are your symptoms affecting daily life?
  • Are you worried about any specific things (for example, has a change in bowel habits made you worry that you have bowel cancer?)

A physical examination may also be carried out during the consultation. This is so your consultant can investigate for any physical signs of concern, such as an unusual lumps and bumps. 

It may be that a diagnosis can be made at this stage, or that your symptoms are nothing to be concerned about. For other symptoms, you may be referred for further tests to investigate specific parts of functions of your digestive system. 

 

Diagnosing gastroenterological concerns 

Depending on your symptoms, you may need to have an endoscopy, a gastroscopy, a colonoscopy or an endoscopic retrograde cholangiopancreatography (ERCP).  

Endoscopy 

One of the most helpful tools when investigating problems within of the digestive system is an endoscopy. An endoscope is a thin, flexible tube with a camera and light at one end. The camera transmits a real time image to a video screen. 

Gastroscopy

A gastroscopy is a type of endoscopy that investigates symptoms in the upper part of the GI tract. The endoscope is introduced into the body through the mouth and then moved down the oesophagus (food pipe), to the stomach and then into the first part of the small intestine. 

Colonoscopy 

A colonoscopy is a type of endoscopy that investigates symptoms in the lower part of the GI tract. The endoscope is inserted into the rectum and then moved along the large intestine and into the lower part of the small intestine. 

Endoscopic retrograde cholangiopancreatography (ERCP) 

An ERCP is used to investigate symptoms that point to a problem in the liver, pancreas, gall bladder or bile ducts. The endoscope is inserted through the mouth and moved into the stomach. A special dye is then injected which shows up on X-rays. Certain conditions can also be treated during an ERCP. For example, if a bile duct is found to be narrowed or blocked, a stent may be inserted to open it up again. If gallstones are discovered in the bile duct, these can often be removed. 

During any of these endoscopic investigations, your consultant will look for any abnormalities or areas of possible concern, such as small lumps or any narrowing in the GI tract. If needed, a biopsy (small sample of tissue) may be taken and sent away for further analysis. 

While not painful, these investigations can be uncomfortable, so you will normally be offered sedation or gas & air (nitrous oxide) to help make things more comfortable for you. 

Additional tests and scans

Additional tests, including blood tests, liver function tests, MRI scan, CT scan and ultrasound, are all available on-site at Shirley Oaks, so are easily arranged if needed. 

Once any investigations have been carried out, your consultant will discuss suitable treatment options with you so that you can make an informed choice about treatment. If you have any questions or concerns at any stage, they will be very happy to talk these through with you. 

If you need to be referred to another specialist (for example, if bowel cancer is discovered you will be referred to the oncology team) this will be done without delay.
