What causes gastroenteritis in pregnant women?

Do you know what causes gastroenteritis in pregnant women? In fact, it is very necessary for patients to clearly understand the causes of symptoms. Understanding the causes of symptoms can help us prevent infectious diseases more actively. So let me tell you what the causes of gastroenteritis in pregnant women are!

The vomiting center is located in the medulla oblongata, and excessive tension can cause vomiting. Vomiting is a series of complex and coordinated reflex actions. First, the cardia contracts and closes, gastric peristalsis, gastric fundus is filled, and then the pylorus opens. At the same time, the abdominal muscles contract, the diaphragm is lowered, and the abdominal pressure increases, so that the gastric contents are discharged from the esophagus and pharynx.

If the gastric peristalsis is poor or the pyloric motility is not moving, the gastric contents are difficult to discharge, but there is a feeling of urge to vomit, which is called nausea and vomiting. The mechanism of the production of vomiting is basically the same as that of vomiting. The only difference between the two is that the intensity of the activity of the vomiting center is different, which leads to different clinical symptoms. When vomiting is accompanied by retrograde peristalsis, the excreta may be contaminated with bile and intestinal contents.

The medulla oblongata has two vomiting tissues with different functions: one is the reflex center - the vomiting center, located at the bottom of the fourth ventricle; the other is the chemical effector horn band, which receives various acid stimuli that cause vomiting.

Vomiting basically controls the actual behavior of vomiting. It receives stimulation from the digestive system and other parts of the body, the cerebral cortex, the vestibular apparatus and chemical effectors to activate apomorphine, sedatives, digitalis, chlorhexidine, uranium chloride and other drugs and compounds, causing the impulse to be transmitted to the vomiting center and causing vomiting.
