Hypotonic solutions are primarily used in medical treatment for rehydration purposes. These solutions have a lower osmolarity than the cells in the body, leading to an osmotic gradient that allows water to move into the cells. When patients are dehydrated, particularly those with conditions that cause fluid loss (like gastrointestinal illnesses or after surgery), administering a hypotonic solution can help restore cellular hydration and promote proper hydration status.

This type of solution is effective in replenishing intracellular fluid, addressing issues such as cellular dehydration. As cells take in fluid, there is a restoration of normal function and metabolism, making it essential for maintaining homeostasis. While hypotonic solutions might indirectly contribute to other processes, such as electrolyte balance, their primary role is focused on rehydrating cells and tissues.
