Symptoms may include abdominal pain, cramping, diarrhoea, dehydration, fever, nausea, vomiting and weight loss.

Coeliac disease – caused by an autoimmune reaction to gluten by genetically predisposed individuals. Eosinophilic enteropathy – a condition where eosinophils build up in the gastrointestinal tract and blood
Inflammation because urethral microbial invasion is the most common cause of urethritis. It is useful to differentiate inflammation and infection as there are many pathological situations where inflammation is not driven by microbial invasion – for example, atherosclerosis, type III hypersensitivity, trauma, and ischemia. There are also pathological situations where microbial invasion does not result in classic inflammatory response—for example, parasitosis, eosinophilia. Acute inflammation is a short-term process, usually appearing within a few minutes or hours and begins to cease upon the removal of the injurious stimulus. It involves a coordinated and systemic mobilization response locally of various immune, endocrine and
