Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.
1. Since she is a diagnosed case of eosinophilic oesophagitis resulting in
esophageal motility disorder [G.E.R.D] thus following preventive aspect can be tried, since I won't recommend any single drug or medicine without first inspecting and examining. Bland and
soft diet, more of milk. Avoid hot drinks and spicy food. Give small, non-bulky meals more frequently [since GERD causes hiccups/ irritability]. Head high position at night. [since GERD causes regurgitation/choking].
2. Management of GERD in both adults and children is based on disease severity, the degree of symptoms, and presence or absence of complications of GERD determined by the diagnostic evaluation, so be under the regular supervision of your attending Physician and one has to keep a watch on other complications arising due to G.E.R.D such as: respiratory and feeding problems.
PS. Presently, there is/are no medications known to cure
eosinophilic esophagitis, although oral/topical
steroids may be prescribed to suppress eosinophil accumulation, relieve damage to the tissue in the
esophagus, and alleviate symptoms.
Hope I have answered your query. Let me know if I can assist you further.
