“…5 Diabetic esophageal dysfunction is clinically important because it may be associated with delayed transit of meals and oral drugs, and gastrointestinal symptoms may decrease the patient's quality of life. [3][4][5][6][7] Common disturbances with respect to esophageal function include reduced amplitude of esophageal contractions, [8][9][10][11][12][13] fewer peristaltic waves, 8,10,14 a decrease in the velocity of peristalsis, 8,15 increased numbers of spontaneous, spastic, and repetitive contractions, [8][9][10][15][16][17] increased frequency of abnormal peristalsis, 12,13,17,18 appearance of multipeaked peristaltic waves, 10,17,19 reduced lower esophageal sphincter (LES) pressure, 8,11,16,20 impaired esophageal transit, 7,12,14,16,17,[20][21][22][23] and abnormal gastroesophageal refl ux. 10,13,…”
