Allergic reactions can affect different areas of the body but are most likely to appear on the skin, in the tummy area and the respiratory tract. Please browse the symptom guide if you are looking for detailed explanations and pictures to each condition possibly caused by food allergy.

Bloat or wind

Bloating is any abnormal general swelling, or increase in diameter of the abdominal area.

Blood in stool

Bloody stools often indicate an injury or disorder in the digestive tract. Your doctor may use the term "melena" to describe black, tarry, and foul-smelling stools or "hematochezia" to describe red- or maroon-coloured stools.

Constipation

Constipation refers to bowel movements that are infrequent and/or hard to pass. Constipation is a symptom with many causes and either comes from an obstruction in the bowel or a very slow mobility of the gastrointestinal tract.

Diarrhoea

Diarrhoea is frequent loose, watery stools. The loss of fluids through diarrhoea can cause dehydration and electrolyte imbalances.

Reflux

Gastro-oesophageal reflux disease (GORD) or acid reflux are chronic symptoms or damage to the mucous membrane caused by stomach acid coming up from the stomach into the oesophagus.

Severe irritability (colic)

Colic (also known as infant colic, three month colic, and infantile colic) is a condition in which an otherwise healthy baby cries or screams frequently and for extended periods, without any discernible reason.

Vomiting

Vomiting (known medically as emesis and informally as throwing up and a number of other terms) is the forceful expulsion of the contents of one's stomach through the mouth and sometimes the nose.
