What happens when dialysis is prolonged?

Explanation

**Step-by-Step Solution:**

1. **Understanding Dialysis**: Dialysis is a process used to separate small molecules from larger molecules in a solution, typically used in medical treatments to remove waste products from the blood when the kidneys are not functioning properly.

2. **Prolonged Dialysis**: When dialysis is prolonged, it means that the process is carried out for an extended period, beyond the normal or recommended duration.

3. **Electrolyte Removal**: During dialysis, electrolytes that are essential for maintaining the stability of colloidal systems in the body are gradually removed from the blood. These electrolytes include ions such as sodium, potassium, calcium, and magnesium.
