Diabetes that develops in pregnancy. This is usually detected during a regular routine Midwifery appointment through high levels of glucose presenting in your urine or other symptoms such as persistent thirst (although many women experience no symptoms at all). It will then be diagnosed during the OGTT Test (definition link). It effects approximately 16% of pregnancies (Diabetes UK) and usually presents in the second trimester (definition link). Typically, it resolves after birth, however, if you develop diabetes in the first trimester (definition link) it is likely that you will have had diabetes before pregnancy which subsequently means it is also likely that it will continue after your baby’s birth.
