People who engage in polypharmacy and other hypochondriac behaviors are at an elevated risk of death from CDI. Other dangers of combining drugs include "brain damage, heart problems, seizures, stomach bleeding, liver damage/ liver failure, heatstroke, coma, suppressed breathing, and respiratory failure", along with many other complications. Disorders like depression and anxiety can also stem from polydrug use. Elderly people are at the highest risk of CDI, because of having many age-related health problems requiring many medications<unk>  with age-impaired judgment, leading to confusion in taking medications. Elderly patients are often prescribed more than one drug within the same drug class, and doctors may treat the side effects of prescribed drugs with even more drugs, which can overwhelm the patient.
