Introduction
Pregnancy Myths & Facts
You Need to Eat for Two
Caloric needs increase by only 300 kcal/day during the second and third trimesters. Eating double portions can cause excessive gestational weight gain.
No Exercise During Pregnancy
Regular moderate exercise is recommended for most pregnant women by ACOG, RCOG, and WHO.
Alcohol in Small Amounts is Fine
No safe level of alcohol consumption during pregnancy has been established. Complete abstinence is recommended.
You Cannot Dye Your Hair While Pregnant
Professional hair dyes have minimal absorption and current evidence does not show significant harm.
Heartburn Means a Hairy Baby
Heartburn is mainly caused by progesterone relaxing the lower oesophageal sphincter, not fetal hair.
Sex During Pregnancy is Unsafe
Sexual activity is safe throughout uncomplicated pregnancies because the baby is well protected.
Baby's Position Changes with Mother's Posture
There is no strong evidence that maternal posture reliably changes fetal lie before term.
Pregnancy Brain is Not Real
Brain imaging confirms measurable structural changes during pregnancy that support the transition to parenthood.
Frequently Asked Questions
Is it safe to eat spicy food in pregnancy?
Yes. Spicy food does not harm the pregnancy, though it may worsen heartburn or nausea in some women.
Does the shape of my bump predict the baby's sex?
No. Bump shape is determined by maternal body shape, uterine tone, and fetal position, not fetal sex.
Conclusion
Accurate information is one of the most valuable things a specialist can offer pregnant women. Addressing pregnancy myths as part of routine antenatal consultations ensures patients navigate pregnancy with facts rather than folklore.
