Lisäjäähdykset

Lisäjäähdykset, often translated as "after-chills" or "secondary chills," is a phenomenon characterized by the recurrence of chills after an initial episode of fever has subsided. This can occur in various medical conditions, particularly infections. While the primary fever may have been treated or is naturally resolving, the body's thermoregulatory system can sometimes trigger further shivering responses.

The exact physiological mechanisms behind lisäjäähdykset are not always fully understood but are thought to involve continued fluctuations in the body's set point for temperature. Even as the underlying cause of the fever diminishes, residual inflammatory processes or unresolved immune system responses might lead to these subsequent chills. This can be a concerning symptom for patients, as it may be mistaken for a worsening of the illness.

Lisäjäähdykset are commonly observed in bacterial and viral infections, such as influenza, pneumonia, or urinary tract infections. In some cases, they can also be associated with non-infectious inflammatory conditions or even certain medications. Medical evaluation is often recommended to determine the cause and ensure appropriate management, especially if the chills are severe, prolonged, or accompanied by other new or worsening symptoms. Treatment typically focuses on addressing the underlying condition that is provoking the chills.
