What Happens When Homeostasis Is Not Maintained?

When homeostasis is not maintained, the body cannot function properly and illness may ensure. Homeostasis is the process in which the body’s overall internal environment is kept constant in response to any external environmental changes. This involves maintaining stability in different body systems.

The body consists of millions of cells that work together to keep the body running through processes like the circulatory, immune, respiratory, nervous and endocrine systems. For example, blood glucose level is an internal condition regulated by the hormone insulin. When blood sugar levels are high and cannot be controlled, it can lead to diabetes and other medical conditions. Other internal conditions that require regulation for homeostasis are body temperature and water content.
