Tests can be performed in one of the clinics, or by purchasing a testing kit.

Small Intestinal Bacterial Overgrowth (SIBO) occurs when there is too much bacteria in the small intestine. The bacteria interfere with digestion and absorption in the small intestine. Symptoms vary amongst people. Common symptoms can include bloating, diarrhoea, nausea, constipation, fatigue, stomach cramps, altered bowel habit, weight loss, weight gain. Some studies have shown that up to 80% of people with IBS have SIBO. Read on for causes, testing and FAQ.
Helicobacter Pylori is a very common infection (present in up to 50% of the population) that is thought to be a factor in the development of stomach and duodenal ulcers (peptic ulcers). It is a bacterium that causes chronic gastritis (inflammation) of the stomach lining. Symptoms of peptic ulcers include loss of appetite, nausea, vomiting, abdominal pain/discomfort. Some ulcers may bleed which can cause fatigue.
Helicobacter Pylori is a common infection that can cause inflammation of the stomach and is thought to be involved in the development of peptic ulcers. It is found in half of the world’s population.
Lactose Malabsorption occurs when there is an inability to fully digest the ‘milk sugar’. Symptoms can begin soon after eating or drinking lactose containing food or drinks.
Fructose and Sorbitol are quite often found together in fruit or added to processed foods. Some people have trouble absorbing these sugars properly when they are consumed at the same time. This can lead to symptoms such as bloating, cramps, diarrhoea/constipation, gas, nausea, or wind.
Fructose can be present naturally in foods such as fruit and some vegetables, or found in many processed foods and drinks. Foods that contain fructose include oranges, apples, mangos, pears, prunes, melons, raisins, honey and fruit juices. Fructose malabsorption occurs when the small intestine fails to fully absorb this sugar. As a result, fructose is transported to the colon where it is broken down by bacteria in the colon. Hydrogen, methane and carbon dioxide gases are produced as a result of this malabsorption.
Sorbitol is often used as a sweetener in “diet” or “sugar free” foods and drinks. It can also occur naturally in foods such as pears, prunes, peaches, cherries, and plums. In large quantities, Sorbitol may cause osmotic diarrhoea, however in patients that suffer from IBS, lower amounts of Sorbitol can cause abdominal and gastrointestinal symptoms.
Sucrose is normally broken down in the small intestine by the sucrase enzyme. When Sucrose Malabsorption occurs, the sucrose is not properly broken down or absorbed in the small intestine. It travels to the colon where it is broken down by bacteria in the large intestine. Sucrose is also known as table or cane sugar.
The Leaky gut test involves collection of a urine sample following the ingestion of a testing solution. The solution contains molecules of different sizes and the rate that these molecules pass through the intestine is measured to give an analysis of intestinal permeability and tight junction activity.
In patients presenting with symptoms suggestive of IBS or IBD, NICE* recommends the use of faecal calprotectin analysis, as a first-line test, to rule out IBD. The test may avoid the need for IBS patients to undergo endoscopy procedures.
Vitamin B12 (also known as Cobalamin) is an important vitamin for maintaining healthy nerves and cells. Some Vitamin B12 is used by the body and some Vitamin B12 is stored in the liver for many years.
Folate or folic acid (Vitamin B9) is a vitamin that is mainly found in leafy green vegetables, nuts, seeds, and citrus fruits. It can also be added to fortified foods such as cereals, or taken as a supplement.
Vitamin D is a fat-soluble vitamin. A fat-soluble vitamin means it can be stored by the body and released when needed.
Ferritin is a protein in cells that contains iron, it reflects the level of stored iron in the body. Having enough iron stores is important, a ferritin deficiency can deplete iron stores quickly.
FODMAPS are a group of carbohydrates (sugars) that may be partially or incompletely absorbed in the small intestine. FODMAP sugars can be found both naturally in food or added to foods during manufacturing.
