What is a common sign that indicates worsening dehydration in clients with diabetes insipidus?

Worsening dehydration in clients with diabetes insipidus is often indicated by weight decrease. This is because dehydration leads to a significant loss of body fluids, which in turn results in a reduction of total body weight. In diabetes insipidus, the kidneys are unable to retain sufficient water, leading to increased urine output and thus fluid loss. As the body becomes more dehydrated, this weight loss becomes more pronounced.

Weight increase is typically not associated with dehydration; it usually indicates fluid retention or an increase in body mass. Regular thirst is a common symptom of dehydration but does not necessarily indicate the severity of the condition. Slight lethargy may occur in dehydration, but it is a more vague symptom and can be influenced by various factors, making weight decrease a more specific sign of worsening dehydration.
