Kate Middleton’s recent hospital stay is creating a lot of buzz, but now that the Duchess has returned home with her husband Prince William, the focus is on her severe morning sickness known as hyperemesis gravidarum (HG), arising the question: Is HG is hereditary or does this mean the future queen is carrying twins.
The morning sickness is what caused the Duchess of Cambridge to be admitted to the hospital and reveal her pregnancy. Dr. Dagni Rajasingnam, a spokesperson for the Royal College of Obstetricians discussed the cause and effects of HG wit People saying, “It's the body reaction to the pregnancy hormone. Some women who are very sensitive to it can start feeling nauseated early on in pregnancy and it will provoke them to take the test."
"The leading theory is that the cause is hormonal," says Dr. Fejzo.
"Obviously when you're carrying twins those hormones are higher, so if you have a problem processing those hormones then you're more likely to feel worse."
Additionally, HG can cause depression in the mother as the severe nausea may cause the mother to think she is neglecting her baby of vital nutrients. The effects of HG can be minimal, only showing during the first few months of pregnancy, or can last months. HG affects only 2 percent of women.
