Short answer:
Pancreas.
Long answer: Normally, blood glucose levels are tightly controlled by insulin, a hormone produced by the Pancreas. Insulin lowers the blood glucose level. When the blood glucose elevates (for example, after eating food), insulin is released from the Pancreas to normalize the glucose level. In patients with Diabetes, the absence or insufficient production of insulin causes hyperglycemia. Diabetes is a chronic medical condition, meaning that although it can be controlled, it lasts a lifetime.
pituitary gland
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.
Parathyroid
No, the thyroid gland is not related to diabetes. Diabetes is a disease relating to the production of the hormone insulin. Insulin is produced by the pancreas (and specifically, by parts of the pancreas known as the Isles of Langerhans), not by the thyroid gland, which produces a hormone called thyroxin.
The pituitary gland may stop working due to factors such as tumors, head trauma, radiation therapy, pituitary apoplexy (sudden bleeding into the pituitary gland), or genetic conditions. These conditions can disrupt hormone production and regulation, leading to pituitary dysfunction.
Yes, it depends on what kind of surgery you have done. Thus, if it is surgery of pancreas, thyroid, or adrenocortical gland, or liver or stomach, these kinds of surgery can cause diabetes as side effects (better check with your doctor before running the surgery and how to take proper care).
The parathyroid gland is most likely not functioning properly if there is too much calcium ion in the blood. This condition is known as hyperparathyroidism, which can lead to high levels of calcium in the blood (hypercalcemia).
Hypo-secretion of antidiuretic hormone (ADH) can be caused by conditions such as diabetes insipidus, which may be due to damage to the hypothalamus or pituitary gland, leading to decreased production or release of ADH. Other causes could include tumors, head injuries, or certain medications affecting the function of the pituitary gland.
Because the pituitary gland is in the brain.
That can cause diabetes insipidus.
The pancreas, it can't supply the body with insulin to maintain blood glucose levels.
Pituitary tumors are the commonest primary intracranial tumors. Panhypopituitarism is unusual as a primary result of a pituitary tumor. Endocrine dysfuncion, particulary reproductive dysfuncion, is common due to GnRh deficiency. Others problem are, hyperprolactinemia, acromegaly, diabetes insipidus, adipsic hypernatremia, syndrome of inappropriate secretion of antidiuretic hormone, hyperthyroisism or hypothyroisism, Cushing Syndrome, Addison disease, hypo or hyperaldosteronism, hypertension, etc, symptoms will dependent on what part of the gland is affect and how.
