gastrointestinal tract allergy

Gastrointestinal food allergies may be defined as clinical syndromes, which are characterized by the onset of gastrointestinal symptoms following food ingestion where the underlying mechanism is an immunologically mediated reaction within the gastrointestinal tract.

The stomach and the digestive system may also be targets of allergy diseases.

These gastrointestinal symptoms, principally vomiting and diarrhoea, sometimes abdominal colic, may be accompanied by other symptoms outside the alimentary tract.

Frequently, eczema and hives may be produced after ingesting of an allergic food. Food allergy may sometimes trigger asthma attacks, rarely generalized anaphylaxis.

It is common to have a reaction to a certain food, but in most cases, it is intolerance rather than a true allergy. Although they may have similar symptoms, Gastro Intestinal allergy can be more serious.

Gastro Intestinal Allergy:

  • Usually comes on suddenly

  • Small amount of food can trigger

  • Happens every time you eat the food

  • Can be life-threatening

Food Intolerance:

  • Usually comes on gradually

  • May only happen when you eat a lot of the food

  • May only happen if you eat the food often

  • Is not life-threatening

Shared Symptoms

Gastro Intestinal allergy and food intolerance both can cause:

  • Nausea

  • Stomach pain

  • Diarrhoea

  • Vomiting

Different Symptoms

When a food irritates your stomach or your body cannot properly digest it, that is intolerance. You may have these symptoms:

  • Gas, cramps, or bloating

  • Heartburn

  • Headaches

  • Irritability or nervousness

Gastro Intestinal allergy happens when your immune system mistakes something in food as harmful and attacks it. It can affect your whole body, not just your stomach. Symptoms may include:

  • Rash, hives, or itchy skin

  • Shortness of breath

  • Chest pain

  • Sudden drop in blood pressure, trouble swallowing, or breathing -- this is life threatening.
