Untreated hypovolemic shock can lead to organ failure due to the significant decrease in blood volume, which results in inadequate perfusion of tissues and organs. When the body experiences hypovolemic shock, whether from severe bleeding, dehydration, or fluid loss, the heart is unable to pump enough blood to meet the metabolic demands of the body's organs. This lack of oxygen and nutrients can cause cells to become damaged or die, leading to systemic complications. Prolonged deprivation of blood flow can affect critical organs such as the kidneys, liver, and brain, ultimately resulting in multi-organ failure if not promptly addressed.

The other options do not correspond to the physiological responses to untreated hypovolemic shock. Improved circulation and increased energy levels are not aligned with the state of shock, as circulation diminishes and energy levels typically decrease due to reduced oxygenation. Weight gain is unrelated as the body's response to shock often involves fluid loss rather than retention.
