Heightened Sense of Smell During Pregnancy: Why It Happens and How to Cope
One of the lesser-known symptoms of pregnancy is a heightened sense of smell, often starting in the first trimester. For many moms-to-be, this increased sensitivity to odors can be both fascinating and overwhelming. Here’s why it happens, how it might affect you, and tips to manage it during your pregnancy journey.
Why Does Smell Sensitivity Increase During Pregnancy?
A heightened sense of smell, known as hyperosmia, is common during pregnancy and is primarily linked to hormonal changes.1. Increased Hormones
- Estrogen: Rising estrogen levels can amplify your sense of smell, making even faint odors seem strong.
- hCG Levels: The same hormone responsible for nausea and morning sickness may also heighten smell sensitivity.
2. Evolutionary Adaptation
- Some researchers believe hyperosmia is a protective mechanism, helping pregnant women avoid harmful substances that might affect their baby.
When Does It Start and How Long Does It Last?
- Onset: Many women notice a heightened sense of smell in the first trimester, often coinciding with morning sickness.
- Duration: For most, this symptom decreases after the first trimester but may persist throughout pregnancy.
How Heightened Smell Affects Pregnancy
Positive Effects:

Tips to Manage a Heightened Sense of Smell
- Identify and Avoid Triggers:

When to Call Your Doctor
