Common Pregnancy Myths Debunked: What’s True and What’s Not

Here are some common pregnancy myths debunked.

Morning Sickness Only Happens in the Morning: Morning sickness can occur at any time of day.

Morning sickness, despite its name, can occur at any time of the day or night during pregnancy. It is not limited to just the morning. This nausea and vomiting can happen in the afternoon, evening, or even be constant throughout the day for some pregnant individuals. The term “morning sickness” is somewhat misleading, as it doesn’t accurately reflect the timing or duration of this common pregnancy symptom.

Pregnant Women Should Eat for Two: You only need about 300-500 extra calories during pregnancy.

The myth that pregnant women should “eat for two” suggests that they should double their calorie intake, which is not accurate. During pregnancy, it is essential to provide proper nutrition for both the mother and the developing baby, but this doesn’t mean doubling your daily caloric intake. On average, most pregnant women need only about 300-500 extra calories per day to support the growing fetus and meet their increased energy needs.

These extra calories should ideally come from nutrient-dense foods, such as fruits, vegetables, lean proteins, and whole grains, to ensure that both the mother and the baby receive essential nutrients. Consuming excessive calories can lead to unnecessary weight gain during pregnancy, which may pose health risks. Therefore, it’s crucial for pregnant women to focus on the quality of their diet rather than simply eating more food. Consulting with a healthcare provider or a registered dietitian can help tailor calorie and nutrient intake to individual needs during pregnancy.

Avoid All Seafood: Some fish are safe and provide essential nutrients; just avoid high-mercury fish.

The notion that pregnant women should avoid all seafood is a misconception. While it’s true that some types of fish should be limited or avoided during pregnancy due to their high mercury content, seafood can also be a valuable source of essential nutrients. Here’s an explanation:

Safe Seafood: Many types of seafood are rich in nutrients like omega-3 fatty acids, which are crucial for fetal brain and eye development. Examples of safe seafood options for pregnant women include salmon, trout, sardines, and anchovies. These fish are generally lower in mercury and provide important nutrients like protein and essential fatty acids.

High-Mercury Fish: Certain fish, particularly larger predatory species like shark, swordfish, king mackerel, and tilefish, tend to accumulate higher levels of mercury. Mercury is a neurotoxin that can be harmful to the developing nervous system of the fetus. Therefore, pregnant women are advised to avoid or limit the consumption of these high-mercury fish.

Variety is Key: To enjoy the benefits of seafood while minimizing the risks, pregnant women are encouraged to consume a variety of fish and shellfish, choosing options that are lower in mercury. Additionally, cooking methods like baking, grilling, or steaming are recommended to reduce the risk of foodborne illnesses that can be associated with raw or undercooked seafood.

Overall, seafood can be a valuable part of a healthy pregnancy diet when chosen wisely, focusing on low-mercury options that provide essential nutrients without unnecessary risks.


Heartburn Means Your Baby Will Have a Lot of Hair: There’s no scientific basis for this claim.

The idea that experiencing heartburn during pregnancy is a sign that your baby will have a lot of hair is a popular old wives’ tale, but it lacks scientific evidence or a logical connection. Here’s an explanation:

Heartburn in Pregnancy: Heartburn during pregnancy is a common symptom caused by hormonal changes and the physical pressure exerted on the stomach by the growing uterus. It occurs when stomach acid flows back into the esophagus, causing a burning sensation in the chest or throat.

Baby’s Hair Growth: The amount of hair a baby has at birth is primarily determined by genetics, specifically the genetic factors related to hair growth that are inherited from both parents. There’s no known biological or physiological link between the mother’s experience of heartburn and the baby’s hair growth.

In essence, heartburn during pregnancy and the amount of hair a baby has are unrelated. While it’s a charming and harmless myth, scientific research does not support any causal connection between maternal heartburn and the hairiness of the newborn. Baby hair growth is determined by genetic factors and normal developmental processes, rather than the presence or absence of heartburn during pregnancy.


You Can’t Exercise During Pregnancy: Exercise is generally safe and beneficial, but consult your doctor.

The statement “You can’t exercise during pregnancy” is a myth. In fact, exercise during pregnancy is generally safe and can offer several benefits to both the mother and the developing baby. However, it’s essential to consult with a healthcare provider before starting or continuing an exercise regimen during pregnancy. Here’s an explanation:

Benefits of Exercise During Pregnancy:

Improved Physical Health: Regular exercise can help maintain overall physical fitness, which can be beneficial during labor and delivery.

Emotional Well-being: Exercise can help reduce stress, anxiety, and symptoms of depression often experienced during pregnancy.

Weight Management: Staying active can help manage weight gain within healthy limits during pregnancy.

Reduced Swelling and Discomfort: Exercise can help alleviate common discomforts like back pain and swelling in the extremities.

Improved Sleep: Regular physical activity can contribute to better sleep quality.

Preparation for Labor: Certain exercises and stretches can help strengthen the pelvic floor muscles and may assist in labor and delivery.

Consulting a Healthcare Provider:

While exercise during pregnancy is generally encouraged, it’s crucial to consult with a healthcare provider for several reasons:

Individualized Guidance: A healthcare provider can assess the mother’s overall health and make recommendations based on her specific circumstances.

Risk Assessment: Some medical conditions or complications in pregnancy may warrant restrictions on certain types of exercise.

Safety Precautions: A healthcare provider can provide guidance on safe exercise routines and proper techniques.

Monitoring: Regular check-ups can help monitor the health of both the mother and the baby throughout the pregnancy.

Adjustments: As the pregnancy progresses, exercise routines may need to be modified to accommodate physical changes.

In summary, exercise during pregnancy is generally safe and can provide various benefits. However, it’s essential to consult with a healthcare provider to ensure that the exercise plan is appropriate and safe for the individual pregnancy, taking into account any specific health conditions or concerns.


You Can Predict Gender by Belly Shape: The way your belly looks does not determine the baby’s gender.

The belief that you can predict the gender of a baby by the way a pregnant person’s belly looks is a common misconception, but there is no scientific basis for this claim. Here’s an explanation:

Belly Shape and Gender Prediction:

The shape and size of a pregnant belly are primarily influenced by factors such as the mother’s body type, the position of the baby, the number of pregnancies she has had, and the stage of pregnancy. These factors are not indicators of the baby’s gender. The baby’s sex is determined by genetic factors, specifically whether the baby carries two X chromosomes (female) or an X and a Y chromosome (male). This genetic information is determined at conception and remains constant throughout the pregnancy.

Misconceptions About Belly Shape:

There are various myths and old wives’ tales that attempt to link belly shape to gender prediction. For example, some people believe that carrying low indicates a boy, while carrying high suggests a girl. Others think that the shape of the belly, such as a round belly versus a more elongated one, can provide clues. However, these beliefs lack scientific credibility.

In reality, the way a pregnant belly looks is a result of the individual’s unique anatomy and the growth of the baby within the uterus. It has no bearing on the baby’s actual gender. The only reliable ways to determine a baby’s gender are through medical tests like ultrasounds or genetic testing.

In summary, there is no scientific basis for predicting a baby’s gender based on the shape or appearance of a pregnant person’s belly.

Caffeine Must Be Completely Avoided: You can consume moderate amounts of caffeine, but limit it.

Pregnant Women Shouldn’t Travel: Travel is generally safe; consult your doctor and take precautions.
Raising Arms Above the Head Can Strangle the Baby’s Umbilical Cord: This is a myth with no scientific basis.
You Can’t Take Any Medications During Pregnancy: Some medications are safe; consult your doctor.
Pregnant Women Should Avoid Sex: In most cases, sex is safe during pregnancy unless advised otherwise by a doctor.
Eating Spicy Foods Induces Labor: Spicy foods do not trigger labor.
You Should Avoid Vaccines During Pregnancy: Some vaccines, like the flu and Tdap, are recommended during pregnancy.
Pregnant Women Shouldn’t Dye Their Hair: Hair dye can be used safely, especially after the first trimester.
Stretch Marks Can Be Completely Prevented: Genetics play a significant role, and creams can only help to some extent.
