Sleeplessness and vomiting are clinical symptoms, and many problems can cause sleeplessness and vomiting: first, we should ask the patient if she has eaten too much or eaten unclean food, which may cause food poisoning, sleeplessness, nausea, vomiting, and also abdominal pain. Secondly, if you are a young female patient, ask if you have menopause and if you have symptoms of early pregnancy, you should go to the hospital to do blood or urine HCG tests in the obstetrics and gynecology department. Thirdly, if the patient is elderly and has trouble sleeping, vomiting, and dizziness, the patient should be alerted to any acute attack of cerebrovascular disease and go to the hospital for a cranial CT or MRI examination. Fourth, if the patient is febrile, he may also have trouble sleeping, nausea and vomiting, so he can go to the hospital for routine blood tests.
