The loss of function resulting from the required removal of a diseased organ is iatrogenic, as in the case of diabetes consequential to the removal of all or part of the pancreas. The incidence of iatrogenesis may be misleading in some cases. For example, a ruptured aortic aneurysm is fatal in most cases; the survival rate for treatment of a ruptured aortic aneurysm is under 25%. Patients who die during or after an operation will still be considered iatrogenic deaths, but the procedure itself remains a better bet than the probability of death if left untreated. Other situations may involve actual negligence or faulty procedures, such as when pharmacotherapists produce handwritten prescriptions for drugs. Adverse effects
A very common iatrogenic effect is caused by drug interaction, i.e., when pharmacotherapists fail to check for all medications a patient is taking and prescribe new ones that interact agonistically or antagonistically (thereby potentiating or attenuating the intended therapeutic effect). Such situations can cause significant morbidity and mortality. Adverse reactions, such as allergic reactions to drugs, even when unexpected by pharmacotherapists, are also classified as iatrogenic. The evolution of antibiotic resistance in bacteria is iatrogenic as well. Bacterial strains resistant to antibiotics have evolved in response to the over prescription of antibiotic drugs.Certain drugs are toxic in their own right in therapeutic doses because of their mechanism of action. Alkylating antineoplastic agents, for example, cause DNA damage, which is more harmful to cancer cells than regular cells.

Collecting stem cells
It is currently possible to collect two types of stem cells during childbirth: amniotic stem cells and umbilical cord blood stem cells. They are being studied as possible treatments of a number of conditions. Placentophagy
Some animal mothers are known to eat their afterbirth, called placentophagy. In some cultures the placenta may be consumed as a nutritional boost, but it may also be seen as a special part of birth and eaten by the newborns family ceremonially. In the developed world the placenta may be eaten believing that it reduces postpartum bleeding, increases milk supply, provides micronutrients such as iron, and improves mood and boosts energy. The CDC advises against this practice, saying it has not been shown to promote health but has been shown to possibly transmit disease organisms that were passed from the placenta into the mothers breastmilk and then infecting the baby.
