Final answer:
Osmotic diuretics promote water loss by osmosis and can lead to increased excretion of glucose and water.
Step-by-step explanation:
Osmotic diuretics promote water loss by osmosis. In the case of poorly controlled diabetes mellitus, glucose levels exceed the capacity of the tubular glucose symporters, resulting in glucose in the urine. The unrecovered glucose becomes a powerful osmotic diuretic. Additionally, sodium has a strong osmotic effect and attracts water. Too much sodium in the body can lead to metabolic problems and an increase in total volume of water, resulting in hypertension. Therefore, osmotic diuretics lead to increased excretion of glucose and water.
