What happens if homeostasis is disrupted in a living organisms

A failure of homeostasis - the balance of essential physiological states - can mean disaster for an organism. If your body temperature falls too low or goes too high, you might experience hypothermia or heatstroke, which can both be life-threatening. If your body can't maintain its energy balance, you might develop obesity or diabetes. If the amount of calcium in your blood becomes too low or too high, you could develop hypocalcemia or hypercalcemia. And if water balance becomes a problem, you might become dehydrated or hyper-hydrated, both very dangerous when extreme.
