Due to episodes of dizziness and weakness for six years, he was admitted to hospital on April 11, 1994 for “pancreatic islet beta cell tumor.” Symptoms often occur when you are hungry, with 3 to 4 episodes per day. Symptoms can be relieved after eating. Due to the above symptoms, the patient had been admitted to the hospital in July 1990 for diagnosis and treatment. At that time, fasting blood glucose was 1.67-3.17 mmol/L, and plasma insulin was 6.10-28.70 μIu/ml. During the hungry experiment (starving for 20 hours), the patient was sweating, ambiguous, crying, blood sugar 1.67mmol/L, 50% static push, and the symptoms disappeared after glucose.
