What patient demographic does Fresenius primarily serve?

Fresenius primarily serves patients with chronic and acute kidney diseases because their services are focused on providing dialysis and related treatments to individuals suffering from renal impairment. This includes patients who have kidney failure, either acute or end-stage, and require regular dialysis to maintain their health. The emphasis on kidney-related conditions aligns with Fresenius' specialization in nephrology, making them a crucial provider in managing the health of these patients.

In contrast, the other demographics mentioned do not align with Fresenius' core mission and services. For instance, children with minor health issues, healthy individuals seeking preventative care, and pregnant women in need of special care typically require services outside the scope of what Fresenius specializes in. Therefore, the selection of patients with chronic and acute kidney diseases accurately reflects the primary focus and expertise of Fresenius.
