Bleeding can raise special concerns in different groups of people, most specifically children and pregnant people.
Children
Unlike adults, children may not be able to describe the symptoms they have. Instead of complaining of pain, they may become fussy, cry continually, or become difficult to console. They may also have a poor appetite or refuse to eat.
Changes in mental status are also common clues. For instance, a child who normally loves to play may become lethargic. Changes in vision can cause a child to bump into walls or miss objects they are reaching for.
Pregnancy
Early on in pregnancy, bleeding may be the sign of a miscarriage or a more potentially deadly condition called an ectopic pregnancy. Later on, placenta previa, placental abruptions, or uterine rupture can cause internal bleeding.
Complications like these often cause vaginal bleeding, but this is not always the case. The position of the baby in the womb may prevent blood from escaping. This can increase the risk of a late diagnosis and death.
