Can Airport Scanners Detect Pregnancy?

Traveling during pregnancy can be daunting, especially when it comes to going through airport security. As you make your way through the security checkpoint, you may be wondering: can those full-body scanners actually detect that you’re pregnant?

The quick answer is: no, airport scanners cannot directly detect pregnancy. Here’s what you need to know about how pregnancy affects airport security screening.

How Full-Body Scanners Work

Airport security has become increasingly stringent in recent years, with full-body scanners being one of the most advanced tools used to detect potential threats. These scanners can reveal hidden objects, including weapons and explosives, that may be concealed on a person’s body.

But can they also detect pregnancy?

Millimeter wave technology

One type of full-body scanner uses millimeter wave technology. This technology emits harmless electromagnetic waves that are reflected off the body and then captured by sensors. These sensors create a three-dimensional image of the body, allowing security personnel to identify any suspicious objects or anomalies.

While millimeter wave technology is effective at detecting weapons and other objects, it cannot specifically detect pregnancy. The waves used by these scanners do not penetrate the body deeply enough to detect a developing fetus or any changes in the body related to pregnancy.

Backscatter X-ray technology

Another type of full-body scanner uses backscatter X-ray technology. This technology uses low levels of X-rays to create an image of the body, highlighting any objects that may be hidden. However, similar to millimeter wave technology, backscatter X-rays cannot detect pregnancy.

The primary purpose of these scanners is to identify potential security threats, rather than personal medical conditions. They are designed to detect objects that may pose a risk to the safety of passengers and crew members.

Limitations of airport scanners

While full-body scanners are an important tool in airport security, they do have limitations. For example, they cannot detect objects hidden internally, such as drugs swallowed by a person. Additionally, certain items, such as non-metallic explosives or plastic weapons, may not be easily detected by these scanners.

It’s worth noting that pregnant women can request an alternative screening method, such as a pat-down, if they have concerns about passing through a full-body scanner. The goal of airport security is to ensure the safety of all passengers while respecting their privacy and individual needs.

Why Airport Scanners Don’t Detect Pregnancy

Airport scanners are commonly used for security purposes to detect prohibited items and potential threats. However, they are not designed to detect pregnancy. Here are a few reasons why airport scanners cannot detect pregnancy:

Scanners don’t look for physical changes

Airport scanners primarily use X-ray technology or millimeter wave technology to create an image of a person’s body. These scanners are focused on detecting objects that may pose a security risk, such as weapons or explosives.

They are not designed to identify physical changes in the body, such as a developing fetus.

While X-rays can penetrate the body and create an image of the internal structures, they are not sensitive enough to detect the presence of a pregnancy in its early stages. The amount of radiation emitted by airport scanners is considered to be very low and safe for most individuals, including pregnant women.

However, as a precautionary measure, pregnant women are often given the option to opt-out of the scanner and choose an alternative screening method.

Operators can’t tell from the scan

Even if an airport scanner could detect physical changes associated with pregnancy, the operators who monitor the scanners would not be able to determine if a person is pregnant just by looking at the scan image.

The images produced by airport scanners are typically black and white, and they do not provide detailed information about specific body parts or conditions.

Operators are trained to look for potential threats and prohibited items, not to make medical assessments. Their primary focus is on maintaining airport security and ensuring the safety of all passengers.

Medical privacy laws

Another important factor is the protection of medical privacy. Pregnancy is a personal and private matter, and it is not the responsibility of airport security personnel to inquire about a person’s medical condition or disclose it to others.

Medical privacy laws, such as the Health Insurance Portability and Accountability Act (HIPAA) in the United States, prohibit the sharing of personal medical information without consent. Airport scanners are designed to respect these privacy laws and focus solely on security-related concerns.

Precautions for Pregnant Travelers

Traveling during pregnancy can be an exciting and rewarding experience. However, it’s important for pregnant travelers to take certain precautions to ensure their safety and well-being. One common concern among expectant mothers is whether airport scanners can detect pregnancy.

While airport scanners are designed to detect potential threats to security, they are not specifically designed to detect pregnancy. However, there are still a few important steps that pregnant travelers should keep in mind.

Let TSA know you’re pregnant

When going through airport security, it is recommended that pregnant travelers inform the Transportation Security Administration (TSA) officers of their pregnancy. This simple step can help facilitate a smoother security screening process.

By letting the TSA know about your pregnancy, they may provide additional assistance or make accommodations to ensure your comfort and safety.

Request a manual pat-down

If you have concerns about going through the airport scanner, you have the right to request a manual pat-down instead. TSA officers are trained to provide alternative screening methods for individuals who prefer not to go through the scanner.

This option allows pregnant travelers to avoid any potential risks or concerns they may have about the scanner.

Avoid the scanner if concerned

While the scientific evidence suggests that airport scanners are safe for pregnant women, it is understandable that some expectant mothers may still have concerns. If you feel uncomfortable or anxious about going through the scanner, it is your right to decline and request an alternative screening method.

It is always better to prioritize your peace of mind and well-being during pregnancy.

Follow all other security rules

Aside from the scanner issue, pregnant travelers should still follow all other security rules and guidelines. This includes removing shoes, belts, and other metal objects, as well as complying with any liquids or electronics restrictions.

It’s important to remember that these security measures are in place to ensure the safety of all passengers, including pregnant women.

Flying Safely While Pregnant

Traveling by air during pregnancy can be a safe and comfortable experience with a few precautions. Here are some tips to ensure a smooth journey:

Choose an aisle seat

When booking your flight, try to select an aisle seat. This will give you easier access to the restroom and allow you to stretch your legs without disturbing other passengers. It’s also a good idea to request a seat with extra legroom for added comfort.

Stay hydrated

During a flight, it’s essential to stay well-hydrated. Dehydration can lead to fatigue and other discomforts. Drink plenty of water before and during the flight, and avoid excessive caffeine or alcohol intake, as they can further dehydrate your body.

Move around on the plane

Sitting for long periods during a flight can increase the risk of blood clots. To prevent this, take regular walks up and down the aisle. Simple leg exercises, like ankle rotations and calf stretches, can also help improve blood circulation.

If possible, consider booking a seat in the front of the plane, as it tends to have less turbulence, making it easier for you to move around.

Wear compression socks

Compression socks are designed to improve blood flow and reduce the risk of blood clots. Wearing them during the flight can help prevent swelling and discomfort in your legs. Consult with your healthcare provider to determine the appropriate compression level and fit for you.

Talk to your doctor

Before planning any trip during pregnancy, it’s crucial to consult with your doctor. They can provide you with personalized advice based on your specific situation. They may recommend avoiding air travel if you have certain complications or are at a high risk of preterm labor.

Your healthcare provider can also provide you with any necessary documentation or medical clearance you may need for your journey.

Remember, each pregnancy is unique, and it’s important to prioritize your comfort and safety while traveling. By following these tips and consulting with your healthcare provider, you can enjoy a safe and pleasant flight during your pregnancy.


While airport scanners don’t actually detect pregnancy, following some simple tips can help ensure a safe, comfortable trip for pregnant travelers. Let TSA know about your pregnancy, stay hydrated, get an aisle seat, and move around on the plane to promote blood flow.

With the right precautions, you can focus on the excitement of your upcoming arrival!
