On the flip side, studies have shown that women are less likely to be taken seriously when bringing a medical concern or complaint to a doctor. Which might suggest that women are under-diagnosed compared to men.
Men were significant less likely to be taken serious and admitted. However those few who are admitted are then taken more serious, and get more direct treatment than women. From a cultural perspective, men are viewed as always healthy, and in the exceptional case where its proven false then they are expected to be restored back to the norm. Women get the opposite cultural treatment, where they are easy accepted as sick but then the health system gives up and don't expect them to be able to be restored back.
