Morning sickness is a common symptom experienced during pregnancy, especially in the first trimester. Despite the name, it can occur at any time of the day. It typically involves nausea, with or without vomiting, and affects about 70–80% of pregnant women.
Though the exact cause is not fully understood, it's believed to be linked to hormonal changes, particularly due to rising levels of human chorionic gonadotropin (hCG) and estrogen hormones. Tiredness or fatigue, stress, and strong smells can also trigger symptoms.
For most, morning sickness is mild and manageable with lifestyle changes like eating small, frequent meals, staying hydrated, and avoiding trigger foods. However, in severe cases, called hyperemesis gravidarum, it can lead to dehydration and weight loss and may require medical treatment.
While unpleasant, mild morning sickness is usually not harmful to the baby and is often considered a sign of a healthy pregnancy. Symptoms typically improve by the second trimester.
