Efficacy of Dark Chocolate in Achalasia Patients
Recruitment status was: Not yet recruiting
Flavanols, present in dark chocolate, were shown to induce Nitric Oxide synthesis. Since Nitric Oxide facilitates smooth muscle relaxation, it might ease the relaxation of the LES (lower esophageal sphincter)as well.
The objective of the present study is to evaluate tha efficacy of dark chocolate in improving LES relaxation in achalasia patients.
