What is the proper medical term for a patient who suddenly turns pale and feels cold and clammy?

The term "diaphoretic" refers to a condition characterized by excessive sweating, often associated with a pale appearance and cold, clammy skin. This can occur during episodes of stress, shock, or other physiological responses, indicating that the body is reacting to a significant change in condition. In a clinical context, a patient exhibiting symptoms of turning pale and feeling cold and clammy may be experiencing a state of hypoglycemia, shock, or anxiety.

Being diaphoretic can provide important clues about a patient's underlying condition, leading healthcare professionals to consider possible treatments or interventions. The other terms provided refer to different conditions; for instance, hypoglycemic specifically addresses low blood sugar levels, dehydration denotes a lack of adequate fluids in the body, and fainting generally describes a temporary loss of consciousness. While these can be related to a patient feeling cold or clammy, "diaphoretic" is the most directly linked to the symptoms described.
