Can I drink coffee and eat lychees when experiencing gastrointestinal discomfort?

　　Gastrointestinal tract refers to the stomach and intestines. Generally speaking, drinking coffee is not recommended when experiencing gastrointestinal discomfort, while consuming lychee in moderation is acceptable. Detailed explanations are as follows:

　 Drinking coffee is not recommended when experiencing gastrointestinal discomfort, as the caffeine in coffee may irritate the gastric mucosa and the lower esophageal sphincter, leading to symptoms such as gastrointestinal discomfort and food reflux. This irritation may worsen stomach discomfort and trigger conditions such as gastritis, gastric erosion, and gastric ulcers. Additionally, caffeine can stimulate the sympathetic nervous system, potentially causing nervous excitement, insomnia, and increased heart rate, which are unfavorable for the recovery from gastrointestinal diseases.

　　Lychee is a nutrient-rich fruit containing abundant glucose, sucrose, vitamins, and proteins. Consuming it in moderation can help replenish energy and essential nutrients. The flesh of lychee is soft and relatively easy to digest and absorb, thus not imposing significant burden on the stomach and intestines. However, lychee has a warm nature, and excessive consumption may cause heatiness. Patients should control their intake and avoid consuming large amounts at once.

　　When eating lychee, it can be paired with other foods, such as drinking some light salt water, which helps prevent heatiness and reduce the adverse effects of lychee on the gastrointestinal tract.
