I had a cesarean section 5 weeks ago, had pre-eclampsia and a frontal placenta, as a result there was quite a bit of blood loss during the surgery (about 1 1/2 Liters) since i've been home, i've been excessively tired, to the point of malaise, and i have been unable to produce adequate breast milk, is my pituitary or my hypothalamus damaged from the blood loss?
