Nausea isn’t an illness or disease. Instead, it’s a symptom. Nausea or an upset stomach isn’t fun. Nearly everyone at some point experiences the sour gastrointestinal symptom in their lifetime. It can occur in children and adults and with no apparent reason.

Causes of nausea are numerous and can vary by age. Some causes include early pregnancy, food poisoning or other infections and stress. Most people experience an upset stomach with other symptoms, such as vomiting, diarrhea and cramping. The common reasons for nausea often aren’t serious and resolve with home care.1‘Nausea & Vomiting: Treatment & Care.’ Cleveland Clinic, my.clevelandclinic.org/health/symptoms/8106-nausea–vomiting.

1. Morning Sickness

Many women experience nausea and vomiting during the first trimester of pregnancy. Some deal with nausea throughout the second and third trimester, too. Nausea from pregnancy is often relieved through home remedies, including sipping ginger ale and snacking on bland foods, such as crackers. In some cases, safe prescription medicine to reduce nausea is necessary.

Although nausea during pregnancy is often manageable and short-lived, some women develop hyperemesis gravidarum, a severe form of morning sickness. This condition may require IV fluids and hospitalization to stop dehydration and loss of body weight.2‘Morning Sickness.’ Mayo Clinic, Mayo Foundation for Medical Education and Research, 22 Sept. 2018, www.mayoclinic.org/diseases-conditions/morning-sickness/symptoms-causes/syc-20375254.
