When Does Nausea Start in Pregnancy?

Nausea in pregnancy, often called morning sickness, is one of the earliest and most common signs of pregnancy. Although called "morning sickness," nausea can occur at any time of day. Knowing when nausea typically starts in pregnancy can help expectant mothers prepare and manage symptoms effectively.

Typical Onset of Nausea During Pregnancy

Most women experience pregnancy nausea between 4 and 6 weeks after conception, shortly after a missed period. Symptoms usually peak around 8–12 weeks and often improve by the second trimester (14–16 weeks). Some women may experience mild morning sickness throughout pregnancy, while others may not feel nausea at all.

Causes of Nausea in Early Pregnancy

Morning sickness occurs due to multiple factors:

• Hormonal changes: Elevated hCG and estrogen levels can trigger nausea in pregnancy.
• Heightened sense of smell: Pregnant women may become sensitive to odors, which can worsen nausea.
• Digestive changes: Slower digestion during early pregnancy can lead to queasiness.
• Stress and fatigue: Emotional and physical stress can intensify pregnancy nausea.

🤰 Practical Tips for Managing Nausea in Pregnancy

• Eat small, frequent meals to avoid an empty stomach.
• Include ginger, lemon, or mint to soothe morning sickness.
• Stay hydrated with water, herbal teas, or electrolyte drinks.
• Avoid strong-smelling foods that trigger nausea in pregnancy.
• Rest adequately and reduce fatigue to help minimize symptoms.
• Consult your healthcare provider if nausea is severe or causes dehydration.
