Conditions we treat
Irritable bowel syndrome
This is one of the most common conditions affecting the gut. It causes a variety of symptoms. It usually involves treating the predominant symptom/s with probiotics, dietary changes, or drugs.
Acid reflux and GORD
This is a common, chronic and relapsing condition which presents with heartburn and/or regurgitation of gas, liquid or food. Treatment usually starts with dietary changes, and medication to reduce the amount of acid produced by the stomach.
Coeliac disease
Coeliac disease is an autoimmune condition due to a permanent allergy to gluten leading to chronic inflammation of the small intestine; nutrients from food may not be absorbed properly. The most effective treatment is a gluten-free diet. Dr harris can provide diagnosis and help you manage the condition.
Barrett’s oesophagus
Barrett’s oesophagus occurs when a portion of the normal lining at the bottom end of the oesophagus is replaced with columnar mucosa as a protective response to frequent acid-induced damage. It is diagnosed at upper gi endoscopy with biopsies and required long term treatment medical therapy and rarely radiofrequency ablation to remove pre-cancerous cells.
Lactose intolerance
Lactose intolerance is the inability to digest significant amounts of lactose, the predominant sugar found in milk. Fortunately, lactose intolerance is relatively easy to treat. There is no treatment to improve the body’s ability to produce lactase, but symptoms can be controlled through diet.
Ulcerative proctitis or colitis
Chronic Inflammation of the rectum or colon of unknown cause. Diagnosed at colonoscopy with biopsies. Treatment is usually with drugs but sometimes surgery is required.
Colonic diverticulosis
The condition whereby diverticula, or pockets, form from the lining of the colon.These protrusions of the colon lining occur at sites of weakness in the muscle wall possibly due to increased pressure from muscle contractions. Treatment may involve dietary changes and probiotics.
Colorectal polyps
Polyps are (usually) benign growths from the lining of the colon or rectum. Often found as part of a screening programme. Even though polyps are benign, studies have shown that removal does significantly decrease the risk of developing cancer of the colon or rectum in future.
Helicobacter pylori
This is a very common bacterial infection of the stomach lining. Patients who see their GP with indigestion (dyspepsia) may be checked (by a blood, stool or breath test) to see if they are infected with H. pylori and if so, offered treatment to cure the infection to see if the dyspepsia improves.
Small intenstine bacterial overgrowth (SIBO)
Small intestine bacterial overgrowth (SIBO) is a condition where abnormally large numbers of bacteria grow in the small intestine. In people with IBS and SIBO the two most common treatments are probiotics and antibiotics.
Crohn’s disease
This is a chronic inflammatory disease that may affect the lining of the gut from the mouth to the anus. Treatment usually involves medication or in some cases surgery.
Hiatus hernia
A hiatus hernia is when part of the stomach is pushed (herniated) into the lowest part of the chest through an opening (the hiatus) in the diaphragm. Usually diagnosed during an Upper GI endoscopy. Treatment involves medication in the first instance, followed by surgery if necessary.
