Very sorry to hear about the loss and my heartfelt condolences go out to the grieving family. The bluish discoloration of nails and lips is due to the reduced amount of oxygen
in the blood just before and after death (cyanosis
) and is a normal phenomenon. Fluid coming out through the nose is also a common phenomenon seen after death.Bloating
of the stomach also occurs after death due to accumulation of gas inside the abdomen. If she had bloating before death as well, it could have been due to some abdominal problem.
