Diastasis may refer to:

• Diastasis (physiology) is the middle stage of diastole during the cycle of a heartbeat

In pathology, diastasis is the separation of parts of the body that are normally joined together, such as the separation of certain abdominal muscles during pregnancy, or of adjacent bones without fracture.

In physiology, diastasis is the middle stage of diastole during the cycle of a heartbeat, where the initial passive filling of the heart's ventricles has slowed down, but before the atria contract to complete the active filling.
