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.
Electrolytes also control your acidity and pH levels. The more dilute your blood and urine are, the lower the concentration of particles. The less water in your blood, the greater the concentration of particles. Osmolality increases when you are dehydrated and decreases when you have a fluid buildup. Your body has a unique way to control osmolality. When osmolality increases, it triggers your body to make antidiuretic hormone (ADH).
