Inclusion Criteria

Subjects with persisting symptoms (i.e. longer than 6 months) located either in the upper and/or lower abdomen suggestive of lactose intolerance, fructose intolerance, small intestinal bacterial overgrowth (SIBO), functional gastrointestinal disorders (i.e. irritable bowel, functional dyspepsia, functional diarrhea)

If needed, patients will undergo Rx barium enema for characterization of colonic diverticula and severe dolicocolon, as a potential cause of lower intestinal symptoms.

Primary Outcome Measures

Name	Time	Method
Main Objective: To test the efficacy of two different doses (low, standard) of tilattase enzymes on gastrointestinal symptoms and hydrogen excretion in subjects with primary lactase deficiency.;Secondary Objective: Due to the chronic features of the primary lactase deficiency, to assess the outcome of prolonged treatment with tilactase enzymes on: gastrointestinal symptoms, quality of life, markers of osteopoenia/osteoporosis;Primary end point(s): breath H2 excretion and gastrointestinal symptoms
