Hi.Erosions means Thinning of the lining of the Stomach/Duodenum
.It may be drug induced sometimes.Aspirin
may lead to Erosions and Ulcers in the Stomach.Nothing to worry.IF taking Aspirin is compulsory,add a Proton pump
inhibitor which reduces the erosions ,Esophagitis
.Please go for a Biopsy of Barretts oesophagus as it a Pre malignant condition.Hope everything will be normal.Take care.
