Insulin is an endocrine hormone secreted by the pancreas. You could call it endocrine or pancreatic secretion.
Excessive secretion of insulin can be caused by conditions such as insulinoma, an insulin-secreting tumor of the pancreas, or insulin resistance in conditions like obesity or type 2 diabetes. In some cases, certain medications or hormonal imbalances can also lead to increased insulin secretion.
Insulin secretion can decrease due to several factors, including insulin resistance, where the body's cells become less responsive to insulin, leading to reduced secretion by the pancreas. Additionally, conditions such as chronic stress can elevate cortisol levels, which can inhibit insulin production. Disease states like type 2 diabetes or pancreatic dysfunction can also impair the pancreas's ability to secrete insulin effectively. Lastly, certain medications or hormonal imbalances may negatively impact insulin secretion.
Diabetes is caused by any defect onlow or no secretion of insulin orimproper use of insulinInsulin is secreted by the gland "Pancreas". So pancreas is responsible for diabetes, it the cause is low insulin secretion (type II diabetes) or no insulin secretion (type I diabetes).Body cells is not sensitive to insulin, then diabetes type II is caused called as insulin resistance.
The medical term for a condition associated with abnormal insulin secretion and sensitivity is "insulin resistance." This condition can lead to high blood sugar levels and often precedes the development of type 2 diabetes. It is commonly seen in individuals with obesity and sedentary lifestyles.
Endocrine reflex
The sympathetic system tends to inhibit insulin secretion, as it is involved in the "fight or flight" response where energy is needed quickly. On the other hand, the parasympathetic system stimulates insulin secretion, as it is known as the "rest and digest" system that promotes nutrient absorption and storage.
Sulfonylurea drugs work by increasing insulin secretions. Examples include Glucotrol, Amaryl, glipizide and many others.
Diebetics
Hyperinsulinism
insulin resistance
Consuming carbohydrates, especially simple sugars, stimulates the release of insulin from the pancreas. Other factors like certain amino acids, fatty acids, and hormones can also trigger insulin secretion. Insulin secretion plays a key role in regulating blood sugar levels by facilitating glucose uptake into cells for energy production.
