Do you Suffer From?

What is GastroLife?



GastroLife is a clinic that specialises in Hydrogen & Methane and Helicobacter Pylori testing. Tests carried out in the clinic are performed by a fully accredited Gastrointestinal Physiologist. We also perform Food Intolerance testing.

We provide testing for Lactose Intolerance, Small Intestinal Bacterial Overgrowth, Fructose-Sorbitol Intolerance, Fructose Malabsorption, Sorbitol Intolerance, Sucrose Malabsorption and the Helicobacter Pylori infection.

Helicobacter Pylori Test



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.

Helicobacter Pylori testing can be performed to support a diagnosis of Helicobacter Pylori infection or to find out if your treatment for the Helicobacter Pylori infection was successful. A Helicobacter Pylori stool antigen test checks your stool (feces) for Helicobacter Pylori antigens. These are substances that trigger the immune system to fight the infection.

It is recommended that Helicobacter Pylori testing is performed by having biopsies taken during an endoscopy (camera test), having a stool antigen test performed, or a urea breath test(1).

Serology (blood) test is not recommended to diagnose eradication of the Helicobacter Pylori infection as antibiodies to the infection can remain in your system for a long time(2).

A stool antigen test can be performed in the comfort of your own home with no fasting requirement. Testing kits can be purchased directly through the online store 24/7. A Helicobacter Pylori stool antigen test is suitable for both adults and children.

Lactose Intolerance Test



Lactose Malabsorption and Lactose Intolerance can be investigated with a Hydrogen & Methane Breath Test. Malabsorption of lactose 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.

Small Intestinal Bacterial Overgrowth Test



Small Intestinal Bacterial Overgrowth occurs when there is an excessive amount of bacteria inhabiting the small intestine. Symptoms are very similar to those of Irritable Bowel Syndrome (IBS).

Studies have shown that in 50% of IBS diagnosis, Small Intestinal Bacterial Overgrowth is present. The Glucose Hydrogen & Methane Breath Test is performed to detect Small Intestinal Bacterial Overgrowth. Lactulose available upon request.

Fructose-Sorbitol Intolerance Test



Fructose and Sorbitol are quite often found together in fruit. Some people cannot consume both of these sugars together when eaten either combined or at the same time.

This can lead to intolerance reactions such as bloating, cramps, diarrhoea or constipation, gas production, reflux, nausea or vomiting.

Fructose Malabsorption Test



Fructose can be present naturally in foods or added as a sweetener. 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 metabolised by colonic bacteria. The by-products released as a result can cause GI and abdominal symptoms such as nausea, diarrhoea, constipation, bloating and fullness.

Sorbitol Intolerance Test



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 GI symptoms.

Sucrose Malabsorption Test



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 metabolised by colonic bacteria. Sucrose is also known as table or cane sugar.

Food Intolerance Test



Up to 45% of the population suffer from Food Intolerance (Allergy UK) which can cause a wide range of symptoms such as headaches, digestive problems, IBS, bloating, itchy skin, joint pain, weight gain, and low mood to name a few.

A few drops of blood are taken using our simple finger prick blood collection wick system. There are three different tests available depending how many food ingredients you wish to be tested for. These include 75, 100 and 150 plus.
