Glucagon
Made by islet cells (alpha cells) in the pancreas, controls the production of glucose and another fuel, ketones, in the liver. Glucagon is released overnight and between meals and is important in maintaining the body’s gluocseand fuel balance. It signals the liver to break down its starch or glycogen stores and helps to form new glucose units and ketone units from other substances. It also promotes the breakdown of fat in fat cells. In contrast, after a meal, when sugar from the ingested food rushes into your bloodstream, your liver doesn’t need to make glucose. The consequence? Glucagon levels fall. Unfortunately, in individuals with Diabetes, the opposite occurs. While eating, their glucagon levels rise, which causes blood glucose levels to rise after the meal.WITH DIABETES, GLUCAGON LEVELS ARE TOO HIGH AT MEALTIMES
GLP-1 (glucagon-like peptide-1), GIP (glucose-dependent insulinotropic polypeptide) and amylin
GLP-1 (glucagon-like peptide-1), GIP (glucose-dependent insulinotropic polypeptide) and amylin are other hormones that also regulate mealtime insulin. GLP-1 and GIP are incretin hormones. When released from your gut, they signal the beta cells to increase their insulin secretion and, at the same time, decrease the alpha cells’ release of glucagon. GLP-1 also slows down the rate at which food empties from your stomach, and it acts on the brain to make you feel full and satisfied. People with Type 1 Diabetes have absent or malfunctioning beta cells so the hormones insulin and amylin are missing and the hormone GLP1 cannot work properly. This may explain, in part, why individuals with Diabetes do not suppress glucagon during a meal and have high blood glucose levels after a meal.Amylin
Amylin is released along with insulin from beta cells. It has much the same effect as GLP-1. It decreases glucagon levels, which will then decrease the liver’s glucose production, slows the rate at which food empties from your stomach, and makes your brain feel that you have eaten a full and satisfying meal. The overall effect of these hormones is to reduce the production of glucose by the liver during a meal to prevent it from getting too high.
The good news is that amylin is available as a medicine to control post-meal glucagon and blood glucose in individuals with Type 1 Diabetes. (GLP-1 also is available as a medicine as a treatment for Type 2 Diabetes and obesity) 
Epinephrine, cortisol, and growth hormone
Epinephrine, cortisol, and growth hormone are other hormones that help maintain blood glucose levels. They, along with glucagon (see above) are called “stress” or “gluco-counter-regulatory” hormones - which means they make the blood glucose rise. 
Epinephrine (adrenaline) is released from nerve endings and the adrenals, and acts directly on the liver to promote glucose production (via glycogenolysis). Epinephrine also promotes the breakdown and release of fat nutrients that travel to the liver where they are converted into glucose and ketones. Cortisol is a steroid hormone also secreted from the adrenal gland. It makes fat and muscle cells resistant to the action of insulin, and enhances the production of glucose by the liver. Under normal circumstances, cortisol counterbalances the action of insulin. Under stress or if a synthetic cortisol is given as a medication (such as with prednisone therapy or cortisone injection), cortisol levels become elevated and you become insulin resistant. When you have Diabetes, this means your may need to take more Diabetes medication to keep your blood glucose under control. Growth Hormone is released from the pituitary, which is a part of the brain. Like cortisol, growth hormone counterbalances the effect of insulin on muscle and fat cells. High levels of growth hormone cause resistance to the action of insulin.
