title: Onset of Ulcerative Colitis during a Low-Carbohydrate Weight-Loss Diet and Treatment with a Plant-Based Diet: A Case Report.
abstract: Overweight and obesity are global health concerns. Various effective weight-loss diets have been developed, including the Atkins diet. The Atkins diet is known as an extreme low-carbohydrate diet. This diet reduces body weight and has gained widespread popularity. However, the metabolite profiles of such a diet have been shown to be detrimental to colonic health. Therefore, a concern for the long-term health effects of this diet exists. We encountered a case in which ulcerative colitis developed while the patient was following the Atkins diet.A man, 172 cm in height and weighing 72 kg, at age 36 years followed a low-carbohydrate weight-loss diet. His weight decreased to 66 kg as desired. Thereafter he noticed bloody stool. Colonoscopy revealed diffuse inflammation limited to the rectum, and he was diagnosed with ulcerative colitis. He underwent an educational hospitalization for ulcerative colitis. A plant-based/semivegetarian diet was provided during hospitalization. Bloody stool disappeared during hospitalization and he achieved remission without medication for inflammatory bowel disease.This case indicates that an onset of ulcerative colitis can be an adverse event to a low-carbohydrate weight-loss diet.
