Insulin attaches to insulin blance on cells throughout the body, instructing them to open and grant entry to glucose. Therefore, glucagon and insulin work in tandem to control the balance of glucose in the bloodstream. Gonzalez JT, Betts JA. People with type 1 diabetes need to take supplemental insulin to prevent their blood sugar levels from becoming too high. This is a powerful hormone in what has been called the brain—meal connection.

Glucagon at a Glance: Understanding Its Functions and Mechanisms

Glucagon hormone balance -

The pancreas is very close to the stomach. As soon as food is eaten, the pancreas releases digestive enzymes into the bowel to break food down. As the food is digested, and nutrient levels in the blood rise, the pancreas produces insulin to help the body store the glucose energy away.

Between meals, the pancreas does not produce insulin and this allows the body to gradually release stores of energy back into the blood as they are needed. Glucose levels remain very stable in the blood at all times to ensure that the body has a steady supply of energy.

This energy is needed for metabolism , exercise and, in particular, to fuel the parts of the brain that 'run' on glucose. This makes sure that the body doesn't starve between meals.

The most important hormone that the pancreas produces is insulin. Insulin is released by the ' beta cells ' in the islets of Langerhans in response to food.

Its role is to lower glucose levels in the bloodstream and promote the storage of glucose in fat, muscle, liver and other body tissues. This has the opposite effect to insulin, by helping release energy into the bloodstream from where it is stored, thus raising blood sugar levels.

Therefore, glucagon and insulin work in tandem to control the balance of glucose in the bloodstream. Other hormones produced by the pancreas include pancreatic polypeptide and somatostatin.

They are believed to play a part in regulating and fine-tuning the insulin and glucagon-producing cells.

Type 1 diabetes mellitus is caused when the body's immune system attacks its own cells in the islets of Langerhans, meaning that these cells cannot produce insulin.

Type 2 diabetes mellitus is a metabolic disorder where the body is no longer able to produce or respond to insulin. Some women also get diabetes temporarily when they are pregnant. This is called gestational diabetes. There are other rarer forms of diabetes, some of which are inherited.

In addition, people will get diabetes if their pancreas is taken away surgically or damaged for instance by severe pancreatitis. Very rarely, patients develop growths tumours of the cells that make up the islets of Langerhans.

These may be benign tumours, where a particular kind of cell multiplies and makes large quantities of its hormone whether it is needed or not. For example, if the tumour is made of insulin-producing cells, it is called an insulinoma.

This is where too much insulin is produced when it is not required. This also happens with glucagon-producing cells, or a glucagonoma, which produces too much glucagon. These and other hormone-producing tumours in the pancreas are very rare, but endocrinology specialists have important parts to play in diagnosing patients with these tumours and contributing to their management and treatment.

The digestive cells of the pancreas can be involved in the condition known as pancreatitis. This is a very painful and serious condition caused by digestive enzymes 'leaking' into the pancreas itself and damaging the delicate tissues in and around it.
