Heartburn or indigestion is common in pregnancy. It too is related to hormonal affects on the stomach and oesophagus (food pipe) and pressure from the growing uterus later in pregnancy.
Nausea and vomiting in early pregnancy is common. It is related to a pregnancy hormone that peaks at approx 10-12 weeks and falls rapidly thereafter.
It is important to have a healthy and varied diet in pregnancy. Almost anything in moderation is a sensible approach however there are some things that should be avoided altogether.
Before attempting to conceive it is desirable that all women have a pre-conception check to ensure that cautions are taken to improve the chances for a successful outcome of pregnancy.
