Health Checks Before Pregnancy
Getting a few health checks done before pregnancy can help you start in the best possible position. Most are simple, quick and worth doing early, from a GP check-up to reviewing medications, nutrition, vaccinations and optional genetic screening.
Here’s what to consider before trying for a baby, and why each check matters.
What health checks should you do before pregnancy?
The main health checks to consider before pregnancy are:
- a preconception check-up with your GP to review your overall health
- a review of any existing conditions and medications, as some may need adjusting before pregnancy
- checking your vaccinations are up to date, including MMR if needed
- checking whether your cervical screening is up to date
- STI testing, especially if there is any chance you or your partner may have an infection
- nutrition and folic acid advice
- lifestyle factors like smoking, alcohol, caffeine, weight, activity and general wellbeing
- genetic or carrier screening, if you want to understand inherited risks that may not show up in family history
You do not need to do everything at once, and a GP can help you work out which checks are most relevant for you. The NHS recommends taking folic acid before pregnancy, checking cervical screening if due, and getting support with smoking, alcohol or drug use if needed.
Why do health checks before pregnancy matter?
Health checks before pregnancy matter because the early weeks of pregnancy are an important stage of development, often before someone even knows they are pregnant. Sorting out things like folic acid, existing conditions, medications and vaccinations in advance means you can be better prepared from the start.
This is not about being perfect or worrying about every detail. It is about giving yourself the healthiest possible foundation before pregnancy.
A GP check-up and your medical history
A preconception appointment with your GP is a good first step. They can review your general health, any ongoing conditions and any medications you take, since some medicines may need reviewing before pregnancy.
If you have a condition such as diabetes, high blood pressure, epilepsy, a thyroid condition or a mental health condition, it can be especially useful to speak to a GP before trying to conceive. Your GP can also help check whether your vaccinations are up to date and whether your cervical screening is due.
Nutrition, lifestyle, and general wellbeing
Small lifestyle steps before pregnancy can make a real difference. Common areas to think about include taking folic acid, eating well, staying active, aiming for a healthy weight, cutting down on caffeine, stopping smoking and avoiding alcohol.
These steps are not about being perfect. They are about giving your body a good starting point. Your GP, midwife or pharmacist can give advice tailored to you rather than relying on general rules.
Where genetic and carrier screening fits in
Genetic and carrier screening is the check many people do not know about, but it can be useful before pregnancy. Carrier screening looks at whether you carry gene changes linked to certain inherited conditions. These changes are often invisible because carriers are usually healthy and may have no family history.
Knowing this in advance can give you and your partner clearer information as you plan. It is a personal choice, not something everyone has to do, and a genetic counsellor can help you understand what the results could mean for you. Carrier screening is recommended for people considering pregnancy and is ideally done before pregnancy if someone chooses to have it.
When should you start?
Ideally, health checks are most useful a few months before trying to conceive. This gives you time to review medications, start folic acid, check vaccinations, arrange screening if needed and make any lifestyle changes without pressure.
That said, it is never too late. If you are already trying or newly pregnant, these checks are still worth doing, so speak to your GP, midwife or healthcare professional as soon as you can.

Questions
What is the most important health check before pregnancy?
There is not one single most important check, but a GP check-up is a good starting point. It can cover your overall health, medications, vaccinations, cervical screening and any existing conditions that may need extra support before pregnancy.
When should I have health checks before pregnancy?
A few months before trying to conceive is ideal, because it gives you time to act on anything that comes up. If you are already trying or already pregnant, it is still worth doing them as soon as you can.
Do both partners need health checks?
It can be helpful for both partners to be involved, especially when it comes to lifestyle, sexual health and genetic or carrier screening. Some inherited conditions depend on what both parents carry, so carrier screening may involve testing both partners.
Is carrier screening necessary if my family is healthy?
Carrier screening is a personal choice. A healthy family history does not rule out being a carrier, because carriers are usually healthy and often have no symptoms. Carrier screening is the most direct way to find out whether you carry certain inherited risks.
