Causes of nausea and vomiting

There are many causes of nausea and vomiting, which can be summarized into the following categories according to the pathogenesis:
Reflex vomiting
(1) Pharyngeal irritation such as smoking, severe cough, nasopharyngeal inflammation or pus.
(2) Acute gastric and duodenal diseases , chronic gastroenteritis, peptic ulcer, functional dyspepsia, acute gastric dilatation or pyloric obstruction, duodenal stagnation, etc.
(3) Intestinal diseases: acute appendicitis, intestinal obstruction, etc.
(4) Hepatobiliary and pancreatic diseases: acute hepatitis, cirrhosis, and liver congestion.
(5) Peritoneal and mesenteric diseases such as acute peritonitis.
(6) Other stones such as renal ureter.
2. Central vomiting
(1) Nervous system diseases Intracranial infections such as various encephalitis; Cerebrovascular diseases such as cerebral hemorrhage; Craniocerebral injuries such as cerebral contusion and laceration; Epilepsy, especially persistent.
(2) Systemic diseases: uremia, liver coma, diabetic ketoacidosis, hyperthyroidism crisis, parathyroid crisis, etc.
(3) Drugs such as certain antibiotics, anticancer drugs, digitalis and the like can excite the vomiting center and cause vomiting.
(4) Poisoning caused by poisoning such as ethanol, heavy metals and carbon monoxide can cause vomiting.
(5) Psychological factors Gastric neurosis, hysteria, and anorexia nervosa.

Clinical manifestations of nausea and vomiting

Vomiting time
Early morning vomiting in women of childbearing age is seen in early pregnancy. It can also be seen in uremia, chronic alcoholism or functional dyspepsia. Patients with sinusitis may have nausea and nausea in the morning due to pus flowing out of the nostril after stimulation. . Dinner or nighttime vomiting is seen in pyloric obstruction.
2. The relationship between vomiting and eating
Vomiting during or immediately after eating may be pyloric ulcer or mental vomiting; vomiting more than 1 hour after a meal is called delayed vomiting, which indicates decreased gastric tension or delayed gastric emptying. Vomiting after a long meal or several meals is seen in pyloric obstruction, and vomit may have overnight accommodations; recent vomiting after meals is mostly caused by food poisoning.
3. Characteristics of vomiting
If vomiting immediately after eating, nausea is very light, you can eat after vomiting, long-term repeated attacks without affecting the nutritional status, mostly neurological vomiting. Jet vomiting is mostly intracranial hypertension.
4. Nature of vomit
Fermented, spoiled odors suggest gastric retention; fecal odors indicate low intestinal obstruction; no bile indicates that the level of obstruction is above the duodenal nipple; a large amount of bile indicates below this level; those with a large amount of acidic liquid, more It is gastrinoma or duodenal ulcer; those without acidity may be caused by stenosis or achalasia of the cardia; upper gastrointestinal bleeding is often coffee-colored vomit.

Nausea and vomiting

Physical examination
Pay attention to blood pressure, breathing odor, abdominal tenderness, rebound pain, gastrointestinal peristaltic wave and bowel type, abdominal mass, bowel sounds, water vibrations, etc. Nervous system, vestibular nerve function and ophthalmological examination are performed when necessary.
2. Laboratory and other inspections
According to the patient's condition, blood routine, urine routine, uroketone body, blood glucose, electrolyte series, blood gas analysis, urea nitrogen, blood and urine amylase, cerebrospinal fluid routine, and toxicological analysis of vomiting fluid can be selected.
When indicated, do X-ray or plain radiography of the abdomen, barium meal radiography, fiber gastroduodenoscope, electrocardiogram, B-mode ultrasound of the abdomen or brain, CT or magnetic resonance, and cerebral angiography.

Nausea and Vomiting Diagnosis

Diagnosis can be made based on medical history, laboratory tests, and physical examinations.

Nausea and Vomiting Treatment

Based on the active treatment of the cause, the necessary symptomatic treatment is performed.
Gastrointestinal diseases
Lesions in the esophagus, stomach, duodenum through the jejunum, ileum, colon, and rectum can cause nausea and vomiting. Vomiting due to narrowing or obstruction caused by benign or malignant gastrointestinal tract, drug treatment is ineffective. The symptoms of vomiting will only disappear after dilatation, stent placement or surgical treatment to relieve stenosis or obstruction. For patients with achalasia, prior to dilation or surgery, calcium channel antagonists or nitroglycerin can be taken orally half an hour before a meal, which can improve vomiting and obstruction symptoms in the early stage; or try botulinum toxin for local narrow injection . For vomiting caused by acute inflammatory lesions of the gastrointestinal tract, you should actively choose antibiotics and correct electrolyte disorders and vitamin supplements; nausea and vomiting caused by gastrointestinal motility disorders, you can use mosapride and other gastrointestinal motility agents; if vomiting is Caused by gastrointestinal spasm, anticholinergic drugs such as scopolamine can be applied.
2. Liver, biliary and pancreatic diseases
Liver, biliary, and pancreatic diseases are one of the common causes of nausea and vomiting. Nausea and vomiting can be early symptoms of acute viral hepatitis. They often occur at the same time as loss of appetite, greasy food, and fullness in the upper abdomen. After liver protection treatment and proper rest, nausea and vomiting can gradually disappear.

One of the important treatment measures is the application of medications that reduce intracranial hypertension and reduce brain cell edema. Dehydration treatment can not only improve the symptoms of vomiting, but also play a role in protecting or restoring brain cell function.
4. Drug-induced vomiting
Many drugs have adverse reactions that cause nausea and vomiting. Generally speaking, as long as the application of vomiting drugs is stopped immediately, the symptoms of vomiting will be reduced until they disappear, so it is not necessary to apply antiemetic drugs. At present, combined chemotherapy or radiotherapy is often used for certain malignant tumors or hematological malignancies (such as leukemia, malignant lymphoma, multiple myeloma, malignant histiocytosis, etc.), or anticancer drugs are used for certain malignant tumors. Interventional treatment. However, during or after treatment, it can cause serious gastrointestinal adverse reactions, the most prominent manifestations of which are nausea and vomiting. In order to prevent or reduce this adverse reaction, antiemetic drugs can often be used for treatment.
