Nausea is the upper abdomen discomfort and urgency to vomit, and vomiting is a common clinical symptom.Nausea is often the feeling of vomiting, and it can also appear alone. It shows the special discomfort in the upper abdomen. It is often accompanied by the symptoms of virtual, saliva, slow pulse, and reduced blood pressure.
Nausea and vomiting are a more common symptom of clinical digestive medicine. Sometimes they sometimes appear alone and sometimes appear.Under normal circumstances, symptomatic symptoms can be diagnosed and symptomatic can be given according to the patient’s symptoms.However, there are many causes of nausea and vomiting, and sometimes clinical omissions and misdiagnosis rates are also high.
Today, through a mind map, I hope to help everyone better remember the cause of nausea and vomiting.
Clinical doctors of digestives often pay attention to endoscopic images and laboratory examinations, and lack of excavation of medical history and comprehensive clinical analysis.Therefore, in the clinical diagnosis of nausea and vomiting of patients with digestive medicine, it is easy to make an empirical errors in the process of diagnosis. It does not pay enough attention to such diseases that often ignore the patient’s age, gender, signs, and symptomatic treatment.Disposal and misdiagnosis occurred.
In this regard, clinicians should learn lessons and learn from nausea and vomiting, and analyze the medical history, carefully diagnosis, combined diagnosis, and relevant examinations.Including vomiting and onset, such as urgent or slow, whether there is a history of alcoholism, the history of motion sickness, and the history of the same seizure, the history of the past abdominal surgery, the history of female patients, etc.;Or continue; it has something to do with diet and activities; the characteristics of vomit and vomit characteristics and odors, thereby speculating whether to poison, quality obstruction of the digestive tract, etc.;; Whether there is bile, it can distinguish the obstruction above and lower the plane of the duodenum and nipples; according to the amount of vomit, it can determine that there is a supreme digestive tract obstruction, and it is estimated that the amount of liquid is lost.In addition, it is necessary to pay attention to the incentives of the attack, such as posture, eating, drugs, mental factors, and pharynx stimulation.And symptoms frequency, duration, severity, etc.
Accompanied by symptoms is also the main points of identification. For example, those with abdominal pain and diarrhea are more common in acute gastrointestinalitis or bacterial food poisoning, cholera, chrome, and acute poisoning of various reasons;Bilecystitis or gallstone; those with headache and jet vomiting are common in intracranial hypertension or glaucoma; those with dizziness and eye tremor are found in vestibular organ disease; some drugs such as antibiotics and anticancer drugs, etc.The side effects of the drug are related; the morning vomiting of women who are married for childbearing age should pay attention to early pregnancy.
