Food Intolerance & Homocysteine Testing, Crawley, West Sussex

Lorisian specialises in offering laboratory tests that measure food-specific IgG antibodies which are sometimes referred to as food intolerances. The expert team at Lorisian are passionate about offering health screening services that can support wellbeing, underpinned by the principle that each person’s digestive sensitivities are as unique as their DNA.

Endorsed by Medical professionals, Olympians and Elite sports players, Lorisian use a proven scientific method to help pinpoint food triggers that may be affecting an individual’s health and lifestyle.  Our food-specific IgG method has had more papers published about its performance than other food food-specific IgG tests on the market.

Over 45% of the population react adversely to foods that they eat, which whilst not life threatening, can have a massive impact on someone’s quality of work and home life. The way that food can affect our everyday life is often difficult to explain and it is common for people to try and eliminate foods from their diet to help themselves feel better. Often they don’t know which foods to try and eliminate and have to guess. Many people don’t know that identifying food intolerances can be an important element of optimising health and wellbeing.

Lorisian, has 35 years’ experience, specialising in laboratory tests that measure food triggers (food-specific IgG antibodies). Our results offer a fast track or starting point for an elimination diet. The tests are aimed at those that may have food intolerances, and those who want to optimise their diets by avoiding any foods that they are reacting to. Our aim is to promote wellbeing within the pressures of a modern lifestyle.

Food intolerance is a condition with a range of symptoms including gut symptoms, bloating, headaches, migraines, low mood, fatigue, weight gain and skin problems. These symptoms must always be checked out by a Medical Professional. If you have seen a Medical Professional but have not been given a diagnosis for their symptoms then they may be suffering from food intolerance.

What is the difference between allergy and intolerance?

A food intolerance can occur when the body has difficulty digesting certain foods. When this occurs over time, large food particles (proteins) may enter the blood stream and this can cause inflammation. When foods and drinks are digested, the proteins within them are broken down into smaller fragments for easy absorption into the body.  Larger fragments can pass through without breaking down, and sometimes the body reacts by attacking them using antibodies called Immunoglobulin G’s (IgG).

A food-specific IgG reaction should not be confused with food allergies, nor other types of food intolerances, which Lorisian do not test for. These include:

  • Enzyme deficiencies e.g. lactose (milk sugar) intolerance
  • Coeliac disease; requiring lifelong avoidance of gluten
  • Chemical sensitivities e.g. histamine, tyramine, sulphites etc

Food intolerance can cause a wide range of disruptive symptoms such as digestive problems, eczema, migraines and headaches, fatigue, depression and low mood, joint pains and sinusitis. It is always recommended that any concerns are discussed with a doctor first, before taking a food intolerance test. This is to fully investigate the potential causes which may include investigations for coeliac disease and/or lactose intolerance and provide the medical follow up required. It is a fact of life, however, that in many cases there is no medical explanation for symptoms such as these.

For example, medically unexplained symptoms or ‘functional symptoms’ where doctors can’t find a problem with the body that might be the cause, account for up to a fifth of all GP consultations in the UK¹.  These include symptoms such as tiredness, chronic fatigue (ME), depression, anxiety, IBS, fibromyalgia, headaches and migraines, skin rashes and joint pains, runny nose and sinusitis.

Many people with these problems will be given the all clear by their doctor and strongly suspect that food is the root cause of their problems. So what options do they have?

  • Do nothing
  • Choose to remove foods from their diet by second guessing
  • Seek support from a dietician or nutritional therapist and try an elimination diet and challenge method; a method which can be long and laborious (it is difficult to determine the exact combination of relevant trigger foods using this method)
  • Take a food intolerance test to identify their food triggers and fast-track their elimination diet

Homocysteine Testing
The simple and effective way to discover and reduce a number of potential health risks.

We are all becoming more aware of the importance of a healthy diet and active lifestyle but the effects of convenience foods and sedentary lifestyles can make achieving a balance difficult. We are aware of the hazards of smoking and excessive alcohol consumption and we know that including plenty of fresh fruit and vegetables in our diet is important. But, even when we seem to be ticking all the boxes to minimise future health problems, we can still be at risk of a number of diseases because of a substance called Homocysteine.

What is Homocysteine?
Homocysteine is a naturally occurring amino acid involved in essential chemical pathways in the body. Although it is a natural substance, too much of it can be harmful, medical experts are warning that raised levels in the blood could be more concerning that high cholesterol.

What are the effects of high Homocysteine?
High levels of Homocysteine in the blood have been implicated in the following:

  • Heart Disease and Strokes
  • Alzheimer’s and dementia
  • Infertility

Am I at risk?
If you tick any of these boxes, you may be at risk of increased homocysteine levels:

  • If you smoke
  • If you drink alcohol
  • If you drink excessive caffeine
  • If you do little to no exercise
  • If you have a poor diet and/or are overweight
  • If you have diabetes
  • If you have rheumatoid arthritis

Levels can also increase with age, oestrogen deficiency and with some medications, as well as for those following strict vegan or vegetarian diets. Whatever the state of your health a homocysteine test can help to assess your risk – allowing you to take action to reduce that risk and provide piece of mind for the future.

A simple, convenient test

  • Simple fingerprick blood sample
  • Clear, easy to understand results
  • Accurate and reproducible test
