The phenomenon of homeostasis is understood as the ability the body has to stabilise its internal environment despite the ever changing external conditions (Waterhouse‚ 2007). This internal environment is an atmosphere which surrounds the cells and is therefore the medium in which the cells are in direct contact with in the body (Sherwood‚ 2001). The internal environment is essential for cell survival because cells require a constant supply of oxygen and food which is exchanged from the external

The nervous system helps maintain homeostasis Homeostatic control mechanisms have at least three interdependent components: a receptor‚ integrating center‚ and effector. The receptor senses environmental stimuli‚ sending the information to the integrating center. The integrating center‚ generally a region of the brain called the hypothalamus‚ signals an effector (e.g. muscles or an organ) to respond to the stimuli. Positive feedback enhances or accelerates output created by an activated stimulus

Diabetes mellitus is a group of metabolic disorders characterized by elevated levels of blood glucose (hyperglycemia) resulting from defects in insulin production and secretion‚ decreased cellular response to insulin‚ or both. This leads to hyperglycemia‚ which may lead to acute metabolic complications‚ such as diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar nonketotic syndrome (HHNS). Longterm hyperglycemia may contribute to chronic microvascular complications (kidney and eye disease)
