2. Disease Signs

1Appendicitis

Nausea can be caused by nausea, or it can be a sign of a more serious condition, such as a warning sign of a heart attack or stroke. Extreme nausea in women along with cold-like symptoms could be a sign of heart disease. In addition, if you experience nausea, fatigue, or loss of appetite, these may be early symptoms of viral hepatitis and you should go to the hospital for examination in time. Many women experience nausea before their period, and half of women experience nausea during pregnancy. Drinking a cup of mint tea after getting up in the morning may help the symptoms disappear immediately.

2 Occurs after meals: Nausea Possible diagnosis: gastrointestinal disease, hepatitis.

Nausea, vomiting, abdominal pain and diarrhea after meals are mostly caused by gastrointestinal diseases such as indigestion, gastritis, enteritis, dysentery and food poisoning. If nausea is accompanied by anorexia and fatigue, you should be alert to viral hepatitis, seek medical treatment and isolate yourself in time. If nausea is accompanied by throat discomfort, it may be chronic inflammation of the throat. If a woman of childbearing age has not had her period for more than 4 weeks without taking any contraceptive measures (or if her contraception has failed), she should consider whether it is due to early pregnancy.
