Typically starts week 6, peaks weeks 8-11, usually resolves by week 14-16
📊 How Common
Affects 70-80% of pregnant women to varying degrees
Overview
Morning sickness is one of the most common early pregnancy symptoms, characterized by feelings of nausea and sometimes vomiting. Despite its name, morning sickness can strike at any time of day or night.
The condition typically begins around week 6 of pregnancy and peaks between weeks 8-11, when hCG hormone levels are at their highest. For most women, symptoms improve significantly after the first trimester.
While uncomfortable and sometimes debilitating, morning sickness is actually associated with positive pregnancy outcomes and lower miscarriage rates. However, severe cases (hyperemesis gravidarum) require medical attention.

🔍 What Causes It?
- •Rising hCG (human chorionic gonadotropin) hormone levels in early pregnancy
- •Increased estrogen levels affecting the gastrointestinal system
- •Enhanced sense of smell making you more sensitive to odors
- •Slower digestion and stomach emptying due to progesterone
- •Low blood sugar levels, especially in the morning
- •Stress and fatigue amplifying nausea sensations
- •Possible evolutionary protective mechanism against harmful foods
💡 Relief Strategies
- ✓Eat small, frequent meals every 2-3 hours to maintain stable blood sugar
- ✓Keep crackers or dry toast by your bedside and eat before getting up
- ✓Avoid strong smells, greasy foods, and spicy meals that trigger nausea
- ✓Drink ginger tea, ginger ale, or take ginger supplements (250mg 4x daily)
- ✓Try vitamin B6 supplements (25mg 3x daily) - shown to reduce nausea
- ✓Wear acupressure wristbands (Sea-Bands) on pressure points
- ✓Stay hydrated with small sips of water, ice chips, or popsicles
- ✓Get plenty of rest and fresh air - take short walks outside
- ✓Avoid brushing teeth immediately after eating to prevent triggering gag reflex
- ✓Try cold or room-temperature foods which have less odor than hot meals
- ✓Eat protein-rich snacks before bed to prevent morning nausea
- ✓Consider unisom (doxylamine) with B6 after consulting your doctor
