• Pre-eclampsia and high blood pressure are more often found in multiple pregnancies.

• There is more chance of anaemia (low red blood count) in the mother.

• Bleeding before the birth can more easily occur.

• Pre-term labour and bad presentation at birth are discussed under The implications of a multiple pregnancy

• Due to a larger or double placenta the chances of developing gestational diabetes is slightly higher.

• Unfortunately, miscarriage of one twin can sometimes occur.  If this is early in the pregnancy then it is possible that the mother's body will simply absorb any remaining tissue.   If it happens late in the pregnancy then very close observation and follow-up is required.

• Genetic defects have a slightly higher chance of appearing in twins.

There are other very rare problems that can occur with multiple pregnancies that we won't go into here.  Doctors will keep a very close check on the progress of multiple pregnancies and can discover any problems very early.

Remember, one of the most important pieces of advice given to mothers of multiple pregnancies is to avoid stress both physically and mentally.  Put simply, this means DON'T WORRY.  If there are any complications, then deal with them when they arrive, otherwise, don't spend your time thinking about what 'may' happen.
