Food Aversions at 37 Weeks Pregnant
Food aversions — sudden repulsion to foods or smells that were previously tolerated — affect over 80% of pregnant women, most intensely in the first trimester. They often develop alongside morning sickness.
👶 What's Happening at Week 37
Your baby is now the size of a winter melon.
- The baby is now 'early term' — nearly ready for birth.
- Brain and lung maturation continues.
- The baby practices breathing, sucking, and gripping.
🔬 Why You're Experiencing Food Aversions at Week 37
- Rising hCG and estrogen enhance smell and taste sensitivity dramatically
- Protective mechanism theory: the body may reject foods associated with spoilage risk (meat, eggs, poultry)
- Associated with nausea — foods that trigger nausea become aversions
- Neurological changes in smell and taste processing during early pregnancy

Frequently Asked Questions
What are the most common food aversions in pregnancy?
The most commonly reported aversions are to meat (especially chicken and beef), eggs, seafood, garlic, onions, spicy foods, coffee, and alcohol.
Do food aversions indicate the baby's gender?
There is no scientific evidence that specific food aversions indicate the baby's sex, despite the popular theory that aversions to meat predict girls.
When do food aversions go away?
Most food aversions resolve by the end of the first trimester (weeks 12–14), though some persist into the second trimester.
Can food aversions cause nutritional deficiencies?
If aversions are severe and prolonged, they can limit nutrient intake. A prenatal vitamin and guidance from a registered dietitian can help ensure nutritional adequacy.
