stion 55 ed out of Excessive blood loss during childbirth can result in an inadequate amount of blood volume in the mother's body. With decreased blood volume and pressure, the heart becomes incapable of pumping the necessary amount of blood to all the tissues, resulting in damage to the brain, specifically the pituitary gland. Sheehan's syndrome occurs in women when the pituitary gland reduces the amount of hormones it secretes after childbirth. Sheehan's syndrome is initially suspected when a mother is unable to produce milk after having undergone a difficult childbirth resulting in shock from blood loss. Since difficulty with lactation is not an uncommon occurrence, many individuals affected with Sheehan's syndrome are not diagnosed until other problems arise. Marina recently gave birth and is having difficulty with lactation. Furthermore, she is experiencing weight gain and hair loss. She is also complaining about constant fatigue and always needing to wear additional layers to keep warm. Many months later, Marina started noticing that she had not returned to having a period every month. 1. The decrease of which hormone secreted from the pituitary gland is responsible for the absence of a menstrual cycle? (0.5 marks) 2. For the hormone above, compare and contrast the normal hormone feedback loop to that of Marina's. (1 mark)
