It’s estimated that gastrointestinal disease expenditure in the U.S. totals $136 billion annually, exceeding the nation’s yearly spending on heart disease ($113 billion), trauma ($103 billion), and mental health ($99 billion). Gut ailments affect an estimated 60 million to 70 million Americans each year, resulting in over 4 million hospitalizations, 72 million ambulatory care visits, and 236,000 deaths. This is why Dr. André Sommer and Jesaja Brinkmann in 2016 founded Cara Care, a Berlin-based subsidiary of HiDoc Technologies that develops digital treatment strategies for patients suffering from chronic digestive conditions.
