Children vomiting in the middle of the night with a sour smell

We all know that children's stomachs are relatively fragile. Often they will feel stomach discomfort after eating some food. There may be no particularly obvious symptoms during the day, but at night, when the stomach is digesting and moving, the child will feel uncomfortable. At this time, the child will vomit in the middle of the night. So what causes the child to vomit in the middle of the night with a sour smell?

Vomiting is a complex reflex action and an instinct of the human body. It can allow the contents of the stomach and part of the small intestine to flow out of the mouth through the esophagus, and expel harmful substances in the stomach, thereby playing a beneficial protective role. The causes of vomiting can be attributed to the following:

Central nervous system diseases: brain trauma, hydrocephalus, brain tumor, meningitis, cerebrovascular accident. Diseases related to the central nervous system: peripheral vertigo (inflammation or dysfunction of the ear labyrinth - Meniere's disease), glaucoma, and migraine.

Digestive system diseases: diseases of the esophagus, stomach and intestines: acute and chronic gastritis, gastric mucosal prolapse, stomach pain, cardia spasm, reflux esophagitis, pyloric spasm or obstruction, duodenitis, gastroenteritis, intestinal obstruction. Chronic liver and gallbladder diseases, chronic appendicitis.

Other systemic diseases: various infections, high fever, shock, heat stroke, hypoxia, etc.

Drug reactions: furans, anthelmintics, digitalis, anticancer drugs, etc.

Toxic diseases: DDT, organophosphates, oleander, poisonous weeds, etc.

Neurogenic vomiting is a common cause of chronic vomiting.

In clinical practice, doctors diagnose vomiting during pregnancy based on the following symptoms of vomiting: First, whether there is nausea before vomiting. Nausea and vomiting can occur alone or at the same time. The vomitus is generally the contents of the stomach. If it persists, bile and intestinal fluid may be vomited out. The relationship between nausea and vomiting can roughly determine the nature of the disease that causes vomiting.

For example: vomiting occurs suddenly, without any nausea beforehand, and is often accompanied by obvious headache, and vomiting often occurs when the headache is severe. It is common in vascular neurosis headache, concussion, cerebral hemorrhage, encephalitis, meningitis and brain tumors. Vomiting is accompanied by nausea, and the nausea can be temporarily relieved after vomiting. It is common in gastritis, ulcer disease, gastric hole, gastric cancer, intestinal obstruction, peritonitis, etc.

Second, look at the time of vomiting: if vomiting occurs before food reaches the stomach, it is mostly due to esophageal diseases, such as esophageal cancer and esophageal achalasia. Nausea and vomiting after eating, accompanied by abdominal pain and bloating, are common in acute gastroenteritis. Amebic dysentery, etc. Vomiting occurs 2-3 hours after a meal and can be seen in gastritis, gastric ulcer and gastric cancer. Vomiting occurs 4-6 hours after a meal and can be seen in duodenal ulcers. Vomiting that occurs at night and is large in amount and has a fermented smell is common in patients with pyloric obstruction, gastric and duodenal ulcers, and gastric cancer. Nausea and vomiting during pregnancy often occurs in the early morning.

Third, look at the vomiting condition: vomiting is effortless, vomiting occurs after eating, and the amount of vomiting is not large. It is often caused by smelling unpleasant odors or seeing disgusting food, and it belongs to the category of neurosis. Vomiting is in the form of projections and is common in patients with increased intracranial pressure such as encephalitis and meningitis. Vomiting occurs when the mouth is full, which is common in intestinal obstruction.
