In general, if someone has an increased serum osmolality, it is due to either decreased water in the blood or increased solutes. If the person has decreased serum osmolality, it is due to increased fluid levels.
Osmolality of blood increases with dehydration and decreases with overhydration. In normal people, increased osmolarity in the blood will stimulate secretion of antidiuretic hormone (ADH). This will result in increased water reabsorption, more concentrated urine, and less concentrated blood plasma.
