Problems in pregnancy

Some pregnancies develop problems along the way that result in medical complications for both mum and baby.

We understand the importance of providing parents with open and honest advice based on fact, which can help to understand what has happened, the possible reasons for it and how to prevent it happening again.

Pregnancy pains and aches

Whether you have stomach pain, headaches, swollen feet or a high temperature, in many cases it is difficult to know whether your symptoms are serious or not.

Visit this section to see whether you should look for medical help for your problem.

Miscarriage and stillbirth

The death of a baby at any stage in pregnancy is difficult for everyone involved. It’s natural to ask, ‘Why us?’ Regrettably it’s not always possible to give an accurate answer.

Premature birth

Premature birth can be a stressful experience for all involved and, in some cases, very premature babies may not survive or may go on to have long-term health problems.

Pre-eclampsia is thought to affect one in twenty of all pregnancies. In most of these cases, it will be a mild case and may have no effect on pregnancy. Approximately one in two hundred women will go on to develop severe pre-eclampsia.

Toxoplasmosis is a parasitic infection. Normally, this infection does not have symptoms and, in fact, a large percentage of people will never know they have been infected by the toxoplasmosis parasite. However, if you are pregnant and become infected, toxoplasmosis may have serious effects on your baby’s development.

Molar pregnancy

A molar pregnancy is a very rare complication of pregnancy. It occurs when something goes wrong during the fertilisation process. It is caused by an abnormal cell growth of all or part of the placenta.

Ectopic pregnancy

An ectopic pregnancy occurs when the fertilised egg implants itself somewhere other than the wall of the uterus.
