If you have stomach pain and vomiting in the middle of the night, you may have acute gastritis due to cold or irregular diet. Acute gastritis is not only characterized by stomach pain but also by bloating, upper abdominal discomfort with diarrhea. The first thing you should do is to take rest, apply local heat and drink more warm water. Secondly, we should give symptomatic treatment with medication, such as rabeprazole capsule, domperidone tablet, mosapride citrate capsule, gastroparesis granule, Huoxiang Zhengqi oral liquid, etc. If you do not see any relief from oral medication, you need to consult a hospital to improve blood routine and blood electrolyte examination to clarify whether there is an increase in white blood cells. If the increase in leukocytes is indicated, it is considered to be the result of inflammatory infection, and anti-inflammatory and electrolyte replenishment medications should be actively given to treat the symptoms.
