👉 A doctor's fluid, also known as intravenous (IV) fluids or crystalloids, is a type of liquid administered directly into a vein to replace lost fluids and electrolytes or to provide medical treatment. These solutions are designed to mimic the composition of normal body fluids, typically containing water, salts, sugars, and sometimes additional nutrients or medications. IV fluids are used to treat dehydration, manage electrolyte imbalances, support blood pressure, and deliver medications more quickly and effectively than oral or inhaled routes. They can be administered in various concentrations to address specific medical conditions, such as hypovolemia (low blood volume), shock, or renal failure.
