There are two tests commonly used to diagnose GERD. They are X-ray (Barium swallow and meal) and endoscopy.

In pregnancy, however, a careful decision has to be made whether either of these tests are necessary. A decision to carry out such tests in pregnancy must be based on the fact that the need for accurate diagnosis outweigh the potential risk of harm to the foetus.

Personally for GERD symptoms, I do not think there is a need to have either. The risks from x-rays on a developing foetus has been well documented ages ago. No gastro-enterologist would consider this option in pregnancy.

Endoscopy to the lay public seems a safe option in pregnancy but the reality is that to avoid gagging etc. during the procedure, a sedative is given. Since thalidomide, doctors are reluctant to use this group of drugs on pregnant women even if they are in Category A,B or C  by the FDA. Drugs in these categories are considered relatively safe in pregnancy.

As a GP with 27 years experience, I think you should aim to avoid all drugs in pregnancy unless absolutely necessary and if you have to take any medication make sure you are satisfied it is safe.

A GP will reluctantly prescribed a drug for severe vomiting in pregnancy. One drug that was used for over twenty years and considered safe to take during pregnancy, was suddenly withdrawn because of potential side effects on the foetus. Doctors tend to trust the safety profile of a drug the longer it is used and with no reported side effects reported. A lesson I learnt quickly. Do not prescribe in pregnancy unless absolutely necessary.

In pregnancy, avoid drugs if you can.
