Cow's milk protein colitis (aka food protein-induced allergic proctocolitis or FPIAP) - FAQ’s
Cow's milk protein colitis (also called food protein-induced allergic proctocolitis or FPIAP) is a benign, self-limited non-IgE-mediated food allergy that typically presents in otherwise healthy infants with blood-streaked, mucoid stools. It is the most common cause of rectal bleeding in infancy and usually resolves within the first 1-2 years of life.
Plane Tree Pollen Allergy
London Plane irritates in two distinct ways:
Like birch or grass, the tree releases wind-borne pollen. This triggers a standard IgE-mediated allergic response.
As the leaves and seed balls emerge in spring, they are covered in tiny, stiff, umbrella-shaped hairs. These hairs are physically "spiky" and act as a mechanical irritant to the mucous membranes of the eyes and throat.

Walnut and Pecan allergies are rarely outgrown and typically require lifelong vigilance and, in the absence of OIT, the constant presence of an epinephrine auto-injector or Neffy device.
We offer OIT for these allergens as part of our ACE service.
Sesame Allergy and OIT

The classic features of lactose intolerance in infants may include: watery, acidic diarrhoea, abdominal distension, flatulence and, in severe cases, failure to thrive and dehydration (if lactose-containing feeds are continued).
Colic and Food Allergy
The NICE guidelines for infantile colic emphasise reassurance, parental support, soothing techniques such as holding, white noise, motion, and winding, as well as ruling out serious issues, such as feeding problems or allergies. Fortunately, colic typically resolves by the ages of 3 to 6 months.
The Allergic March
The allergic march, aka the atopic march, is a concept describing the possible progression of allergies through childhood.
The "march" is not universal or linear; trajectories vary and are influenced by genetic predispositions, environmental exposures (e.g., the microbiome, pollutants), and immunologic factors.
