What should I do if I experience hypoglycemia during fasting?

When hypoglycemia occurs during fasting or “bigu” (a traditional Chinese practice of abstaining from grains), symptoms can be alleviated by consuming sugar cubes, sweetened beverages, or other quick sources of glucose. If hypoglycemia is severe—manifesting as confusion, loss of consciousness, or syncope—immediate medical attention is required. Intravenous glucose infusion is typically administered to rapidly elevate blood glucose levels.

Many young people today adopt fasting or “bigu” for weight loss, which significantly increases the risk of hypoglycemia. Mild hypoglycemia may present with sweating, palpitations, and hand tremors; severe cases may lead to confusion, coma, or even loss of consciousness. Recurrent hypoglycemic episodes can adversely affect overall health, resulting in fatigue, lethargy, and diminished mental alertness—and are unlikely to yield effective or sustainable weight loss.

Therefore, it is essential to select safe and appropriate weight-loss methods. A balanced diet is key: reduce intake of highly refined grains (e.g., white rice and wheat flour) and instead emphasize whole grains such as buckwheat and corn flour. Include moderate portions of lean protein sources—including fish, chicken, and beef—and consume ample vegetables and fruits to ensure adequate dietary fiber and vitamins. Complement this nutritional approach with regular physical activity—such as running, swimming, or yoga—for optimal, healthy weight management.
