Therapeutic effect of lyophilized, Kefir-fermented milk on constipation among persons with mental and physical disabilities

Aim Constipation is a serious problem for persons with mental and physical disabilities in Japan. However, prophylaxis is extremely difficult because the major causes of constipation in these individuals are related to their mental and physical disabilities. Constipation can be successfully treated with glycerol enemas (GEs) and other aperients. As constipation is a lifetime issue for these persons, dietary regimens to prevent constipation can be important. Methods This study evaluated the probiotic effects of kefir-fermented milk for preventing constipation in 42 persons with mental and physical disabilities. The participants were administered 2 g of lyophilized kefir with each meal for 12 weeks and their bowel movements, the administration of GE and other aperients, and stool shape were recorded. Results The intake of kefir significantly reduced constipation, compared with the baseline status. Some individuals showed complete relief of constipation, whereas others showed no effect. Conclusion Despite individual variations, consuming kefir daily could prevent constipation.
