Nausea during pregnancy is usually caused by changes in hormone levels in the body. This phenomenon is medically known as morning sickness, typically occurring around the 6th week of pregnancy, although the exact timing varies from person to person—some may experience it earlier, others later. Symptoms of nausea may be accompanied by vomiting upon waking, decreased appetite, fatigue, and other common physiological manifestations of early pregnancy. As gestational age increases, these symptoms generally begin to subside or disappear around week 12 of pregnancy. If nausea and vomiting become severe enough to interfere with daily life, prompt medical attention is recommended.
