Diseases can affect the body in various ways, often classified into categories such as infectious, genetic, metabolic, and degenerative disorders. Each type impacts the body differently: - Infectious diseases are caused by pathogens like bacteria, viruses, and fungi. - Genetic disorders result from abnormalities in an individual’s DNA. - Metabolic diseases involve disruptions in normal metabolic processes. - Degenerative diseases are characterized by the progressive deterioration of tissues and organs.
