Patients with SIADH (Syndrome of Inappropriate Antidiuretic Hormone secretion) often exhibit weight gain due to fluid retention. In this condition, the body secretes excessive amounts of antidiuretic hormone (ADH), which causes the kidneys to reabsorb more water than usual, leading to dilutional hyponatremia (low sodium levels in the blood). This excess water retention can result in edema and an increase in body weight, even without changes in dietary intake. Recognizing this symptom is crucial for healthcare professionals, as it can help in the early diagnosis and management of SIADH, allowing for appropriate interventions to restore fluid balance and electrolyte levels.
