Why does drinking coffee and milk tea on an empty stomach make you nauseous?

The reason why drinking coffee and milk tea on an empty stomach can make you nauseous:

Coffee contains more caffeine, and milk tea also contains caffeine, which can stimulate the secretion of gastric acid and increase the concentration of gastric acid. At this time, the stomach, after a night's rest is in a state of emptying, too much gastric acid is easy to damage the gastric mucosa, causing stomach pain, heartburn and even nausea. In addition, drinking a lot of strong coffee on an empty stomach may also lead to rapid heartbeat, chest tightness, palpitations and other discomforts.

And, coffee accelerates the body's consumption of energy, and drinking it on an empty stomach in the morning is likely to lead to hypoglycemia. If you want to drink a cup of coffee in the morning to refresh yourself, it is best to drink it after breakfast. If time is tight, before drinking coffee, it is best to eat some carbohydrate-rich foods, such as bread, buns and a variety of cakes, etc., not only to protect the stomach and intestines, but also for the body to increase energy and improve work efficiency.
