It should be useful to eat gum cake when hypoglycemia occurs, because the gum paste currently on the market adds brown sugar or white sugar or other ingredients during the boiling process, so gum cake is useful to correct hypoglycemia. However, when hypoglycemia occurs, it is more recommended to take sugar cubes or intravenous glucose injection. When patients find hypoglycemia, they need to eat foods with higher sugar content, such as fruits, snacks, drinks, sugar cubes, etc. If hypoglycemia occurs more seriously and the patient becomes obviously impaired in consciousness, eating gum cake may not work, so you should immediately eat high sugar food, feed the patient chocolate, sugar cubes and drinks to correct hypoglycemia in a very short period of time to prevent further aggravation of hypoglycemia leading to coma and damage to brain cells.
