In addition, if the milk tea is too cold, it will also stimulate the gastrointestinal mucosa, causing digestive system dysfunction, manifested as abdominal pain, diarrhea and other discomforts. 2, if the milk tea is not hygienic in the production process, after drinking it may lead to intestinal bacterial infection, acute enteritis, which can lead to abdominal pain, accompanied by diarrhea and even nausea, vomiting, etc. Patients can apply appropriate hot compresses to the abdomen for about 10 minutes and drink some warm boiled water to help relieve the symptoms.
