Introduction
Individuals with strong digestive function and no blood sugar issues can consume a small amount of lychee on an empty stomach to quickly replenish glucose and relieve mild hunger. These individuals have normal gastric acid secretion and gastrointestinal motility, so a small quantity of lychee will not irritate the stomach or intestines. If they promptly follow up with staple foods and protein-rich items, such as bread and eggs, discomfort can be avoided and nutrition can be balanced.

Generally speaking, individuals with good digestive function and normal blood sugar levels may consume a small amount of lychee on an empty stomach, while those with sensitive gastrointestinal systems, abnormal blood sugar levels, or severe hunger when fasting should avoid eating lychee on an empty stomach. If in doubt, it is recommended to consult a healthcare professional in advance. Detailed analysis is as follows:

People with strong digestive function and no blood sugar issues can eat a small amount of lychee on an empty stomach to quickly replenish glucose and relieve mild hunger. In these individuals, gastric acid secretion and gastrointestinal motility are normal, and a small quantity of lychee will not irritate the gastrointestinal tract. If staple foods and protein-rich foods such as bread and eggs are consumed promptly after eating lychee, discomfort can be avoided and nutrition can be balanced.

Consuming lychee on an empty stomach may irritate the gastric mucosa due to its fruit acid content, easily causing stomach pain and acid reflux in individuals with weak gastrointestinal function. For diabetic patients, eating lychee on an empty stomach may lead to a sharp increase in blood sugar levels due to its high sugar content, which is detrimental to disease management. Eating large amounts of lychee when hungry on an empty stomach may stimulate excessive insulin secretion due to fructose, potentially causing hypoglycemia. Moreover, lychee has a warm and hot nature; eating too much on an empty stomach may intensify internal heat and lead to symptoms of excessive internal heat (commonly known as "fire").

When eating lychee on an empty stomach, do not consume more than five lychees at a time, and eat other foods soon afterward. Individuals with sensitive gastrointestinal systems and diabetic patients should尽量 avoid consuming lychee on an empty stomach. If discomfort such as stomach pain or dizziness occurs after consumption, stop eating immediately and monitor the condition, seeking medical attention if necessary.
