Fluid stimulation methods and devices for treating fluid overload

A method for treating fluid overload in a subject, the method comprising shifting fluids directly and non-invasively from an interstitial compartment of the subject to skin of the subject through controlled local fluid loss, thereby removing excess fluid from the interstitial compartment of the subject and treating fluid overload in the subject, wherein the fluid loss is sweating, and wherein sweating is stimulated by controlling relative humidity, airflow, pressure, and temperature within a chamber.

A method of removing fluids through the skin by osmosis comprising:

• fitting a chamber around a body part of a patient, the chamber comprising interstitial electrolytes;
• and
• controlling content and concentration of the interstitial electrolytes in the chamber, thereby driving water and salts out of the body part of the patient while maintaining pH and electrolyte levels of the body part.

A method for treating fluid overload in a subject, the method comprising shifting fluids directly and non-invasively from an interstitial compartment of the subject to skin of the subject through controlled local fluid loss, thereby removing excess fluid from the interstitial compartment of the subject and treating fluid overload in the subject, wherein the fluid loss is sweating that is stimulated by elevating skin temperature of the subject within a chamber.
