Many mothers get scared when they hear the word 'X-ray' during pregnancy. It's perfectly reasonable to be afraid that something will happen to my baby. Imagine, what would you do if you were in an accident, or if you had a toothache and the doctor said you needed to get an X-ray? Is this really something to be afraid of? Let's get rid of the unnecessary fear about this and talk simply about what's really going on and what we need to know.
What is an X-Ray? Why are so many people afraid of it?
Simply put, an X-ray is a special type of radiation that is invisible to the naked eye and is used to see things inside our bodies, such as bones. These are classified as a type of ionizing radiation. Due to some events in history (for example, nuclear explosions during World War II), people have become very afraid of the word radiation.
But the most important thing we all need to understand is that the amount of radiation emitted from an X-ray machine used for medical treatment is not at all that dangerous . It is a very low dose of radiation. Therefore, there is no need to be afraid of every X-ray because of the fear that was there in the past. Scientists have now found that the potential harm to your baby from a single X-ray examination of your arm, leg or tooth is very minimal, if not non-existent.
Does radiation during pregnancy affect the baby?
The baby growing in the womb is somewhat protected from radiation by the walls of your abdomen and uterus . But the baby can still get some. Especially during the rapidly developing fetal stage, cells are very sensitive to radiation.
Only when exposed to very high doses of radiation can certain risks arise. For example:
- Child growth restriction
- Birth defects
- Affecting brain function
- Slightly increased risk of cancer later in life
But these risks only occur with very high doses of radiation . For example, exposure to the amount of radiation that would be received from about 500 chest X-rays in one go would only slightly increase the risk of cancer. Such serious effects are very rare from a single X-ray taken for routine medical purposes.
The period between 10 and 17 weeks of pregnancy is when radiation can have the greatest impact on a baby's brain development. Therefore, doctors try to avoid high-dose radiation tests during this time unless absolutely necessary.
So, what kind of X-rays are safe during pregnancy? What are unsafe?
This is the most important thing. As long as your abdomen, where the baby is, is not directly exposed to radiation, X-rays are generally safe. However, tests that directly expose the abdomen to radiation should be avoided as much as possible. Let's understand this clearly with a table.
| Types of X-Rays That Are Generally Safe | X-Rays and tests that should be avoided as much as possible |
|---|---|
| X-rays of your bones, such as your arms and legs | Abdomen X-ray |
| Dental X-ray | Pelvis and abdominal X-ray |
| Head X-ray | X-ray of the kidneys and lower back |
| Chest X-ray | CT scan - especially of the abdomen and pelvis |
| (All of this should be done while wearing a lead apron) | Barium enema |
Are the effects different at different stages of pregnancy?
Yes, the early stages of pregnancy are the most sensitive.
- During the first 2 weeks: If you receive a high dose of radiation during this time, there may be a risk of miscarriage. Because at this time, the embryo is just a collection of a few cells.
- Between 2 and 8 weeks: If exposed to high doses of radiation during this time, there is a risk of stunted growth or birth defects in the baby.
- Between 8 and 16 weeks: If exposed to high doses of radiation during this time, there is a risk of intellectual and learning disabilities.
Again, we need to remind you that these risks are about high doses of radiation, not a single X-ray taken for a necessary medical reason.
Things we need to know before taking an X-Ray
If you need to get an X-ray, don't panic and follow these steps.
1. Inform your doctor: This is the most important thing. If you are pregnant or think you may be pregnant, tell your doctor before having any medical tests.
2. Ask for a Lead Apron: If you are having an X-ray of your arm, leg, head, or chest, be sure to ask for and wear a lead apron that covers your abdomen. This is like a protective vest. Since it covers your abdomen, the X-ray radiation does not reach your baby.
3. Ask about alternatives: In some cases, other tests can be done instead of an X-ray. Ultrasound scans and MRI scans do not use radiation. Therefore, they are considered very safe during pregnancy. Your doctor will consider these alternatives if necessary.
4. Ask if it can be postponed: If your condition is not an emergency, you can also talk to your doctor about whether the X-ray can be postponed until after the baby is born.
What if an X-ray was taken without you knowing?
Imagine that you had an X-ray when you didn't know you were pregnant. It's normal to feel scared about your baby now. If that happens, don't panic and tell your doctor right away .
Usually, the radiation dose from a single X-ray is very low, so your doctor will tell you not to worry too much about it. However, if you have unknowingly undergone a high-dose test, such as a CT scan or barium study, it is important to talk to your doctor about it and get advice. To prevent this from happening, some hospitals test all women of childbearing age for pregnancy before such tests.
Take-Home Message
- If you are pregnant or suspect you may be pregnant, be sure to tell your doctor before undergoing any medical tests or treatment.
- The risk to your child from a single, essential X-ray examination (especially of the arms, legs, head, or chest) ordered by a doctor is very low.
- Sometimes, the harm of not getting a needed X-ray (e.g., missing a serious fracture) can far outweigh the small risk of radiation. Trust your doctor's decision.
- X-rays of the abdomen, pelvis, and lower back, as well as CT scans and barium studies, should be avoided during pregnancy unless absolutely necessary.
- If you have any fears or doubts about this, or if you had an X-ray without knowing you were pregnant, don't panic and talk openly with your doctor.
