Normal people may have elevated blood glucose during starvation.
In normal people, during a short period of starvation, the organism, in order to maintain the energy supply of the brain, will elevate blood glucose through some metabolic regulation, such as the release of glucagon and glycogenolysis, in order to ensure the stabilization of blood glucose and the supply of glucose to the brain. However, if starvation lasts for too long, glucagon will drop and blood sugar will be lost, resulting in hypoglycemia, which can be manifested as pallor, dizziness, sweating, palpitations, etc.
Normal people who have been starved for a long time may experience hypoglycemia or a rebound type of elevation of blood glucose. It is recommended to replenish food in time when you are hungry, and if you feel unwell, it is recommended that you seek medical attention in a timely manner.
