Publications for Cause Medicine YR 2024 RD 1/8/2024  UL https://doi.org/10.61029/normamed.2024.03.en AB From August 2018 to April 2022, 166 patients with chronic sleep disorders from the patient collective of Ärztehaus Mitte, Berlin, were enrolled in observational studies. The studies offered the observations from the perspective of modern Western medicine and from the complementary medicine perspective of Traditional Chinese Medicine: Gastrointestinal disorders, essentially caused by infections, correlate with sleep disorders. Infections and mixed infections or disorders of the digestive system caused by pathogenic yeasts and H. pylori, in addition to multiple disorders, cause a lasting impairment of spleen and kidney functions. Treatment of the sleep disorders was carried out following the diagnosis by causal treatment of the gastrointestinal disorders with specialist and complementary medical measures. This resulted in improvements in sleep that ranged from good to very good in 76 percent of patients (monitored in 113 patients with adequate monitoring time). The success of treatment through integrated root cause medicine depends on continued compliance of the patient over a longer period of time. Accordingly, the following observations were made: In 90 patients with high compliance, treatment resulted in improvements in sleep that ranged from good to very good in 87 percent; while in 23 patients with low compliance, only 35 percent showed improvements ranging from good to very good.
