Summary

Constipation is one of the common complication of diabetes mellitus, whose pathogenesis was previously recognized as decreased gastrointestinal motility caused by diabetic autonomic neuropathy. It is always treated with gastrointestinal motility drugs or laxatives which may have side effects such as gut microbiota dysbiosis and withdraw symptoms. Recently, researches have indicated that the risk of developing type 2 diabetes mellitus is associated with alterations in the structure of the gut microbiota and have begun to treat diabetic constipation by improving gut microbiota of these patients. The rational use of microecological preparation for the prevention and treatment of diabetic constipation has received increasing attention. This trial is aimed to evaluate the efficacy and safety of Combined Bifidobacterium, Lactobacillus, Enterococcus and Bacillus Cereus Tablets, Live (Siliankang) in the treatment of patients with type 2 diabetes and constipation, and to analyze its influence on gut microbiota and blood glucose.
