The pancreas is an exocrine gland that produces digestive enzymes and hormones. It is not an endocrine gland.

Hormones are chemical messengers that regulate various physiological processes, such as growth, metabolism, reproduction, and mood.

Insulin is a hormone produced by the pancreas that helps regulate blood sugar levels.

Insulin binds to receptors on cell membranes and activates intracellular signaling pathways that lead to the uptake of glucose into cells.

In type 1 diabetes, the pancreas produces no insulin, which leads to high blood sugar levels.

In type 2 diabetes, the cells of the body become resistant to insulin, which leads to high blood sugar levels.

Cushing's syndrome is a condition caused by excessive production of the hormone cortisol. Symptoms include weight gain, muscle weakness, and high blood pressure.

Addison's disease is a condition caused by insufficient production of the hormone cortisol. Symptoms include fatigue, weight loss, and low blood pressure.

Hyperthyroidism is a condition caused by excessive production of the hormone thyroxine. Symptoms include weight loss, increased heart rate, and anxiety.

Hypothyroidism is a condition caused by insufficient production of the hormone thyroxine. Symptoms include fatigue, weight gain, and constipation.

Acromegaly is a condition caused by excessive production of the hormone growth hormone. Symptoms include enlarged hands and feet, coarsened facial features, and deepening of the voice.

Addison's disease is a condition caused by insufficient production of the hormone cortisol by the adrenal glands. Symptoms include fatigue, weight loss, and low blood pressure.
