Nasal polyps are small, curable growths that grow up from nose or sinus tissues and can generate the sinus cavities to become blocked, interrupting mucus from filtering and leading to sinus infection. They can reduce airway passages which can in turn trigger headaches.
Hypotonic solution: A solution that contains fewer dissolved particles (such as salt and other electrolytes) than is found in normal cells and blood. Hypotonic solutions are commonly used to give fluids intravenously to hospitalized patients in order to treat or avoid dehydration.ypotonic solution: A solution that contains fewer dissolved particles (such as salt and other electrolytes) than is found in normal cells and blood.

This type of solution is infused to replace fluid losses, usually extracellular losses, and to expand the intravascular volume. Most isotonic solutions do not provide calories or free water. Examples of isotonic solutions are 0.9% sodium chloride, commonly called normal saline (NS), and lactated Ringerâs (LR). Hypotonic solutions have an electrolyte content of less than 250 mEq/L and are administered to expand the intracellular space.
