The pancreas has cells which produce insulin. Insulin allows the body's cells to absorb glucose from the bloodstream. Diabetes is an auto-immune disease which destroys the insulin producing cells in the pancreas. Without insulin, the body cannot move glucose from the blood stream into cells, where it is needed to produce energy. The result is that glucose builds up in the bloodstream. This is fatal if untreated.
NB: there are 2 main types of diabetes. Type 1, or juvenile diabetes, is of unknown origin and requires regular injections of insulin. Type 2 diabetes is lifestyle related and is caused by such factors as being overweight and unfit.

How does the pancreas control blood glucose levels?
Blood levels of glucagon and insulin are controlled by islets of Langerhans in the pancreas, in which some of the islet cells, called alpha cells, secrete the hormone glucagon and other islet cells, called beta cells, secret insulin.
What cells in the pancreas play a role in diabetes?
Insulin...When the blood-sugar level in your body is too high, your pancreas produces more insulin which then allows the glucose to be absorbed by body cells. The glucose level will then reduce. When the Blood-sugar level is too low, your pancreas does not release insulin, which mean that less glucose is absorbed in body cells. The glucose level in the blood is therefore increased.
Which hormone specifically targets cells that produce hormones that affect glucose metabolism?
Insulin is the hormone that specifically targets cells that produce hormones affecting glucose metabolism. It is produced by the pancreas and regulates the uptake, utilization, and storage of glucose by cells in the body. Insulin helps to lower blood glucose levels by promoting the absorption of glucose from the blood into cells.
What cells carry glucose?
Glucose is primarily carried in the blood stream by red blood cells and muscle cells. Red blood cells transport glucose to various tissues in the body, while muscle cells use glucose for energy production during physical activity.
What happens to the concentration of the blood glucose if not enough insulin is produced?
If not enough insulin is produced, the concentration of blood glucose will increase because insulin is responsible for helping glucose enter cells to be used for energy. Without enough insulin, glucose remains in the bloodstream, leading to high blood sugar levels, a condition known as hyperglycemia.
How does glucose affect red blood cells?
Glucose can bind to hemoglobin and form glycated hemoglobin (HbA1c) in red blood cells. This process is used to monitor blood sugar levels over time in individuals with diabetes. High levels of glucose can also lead to osmotic swelling of red blood cells, affecting their function and potentially causing damage.
How does diabetes mellitus affect your body?
In this disease, the body has no sufficient insulin or has insulin but insensitive cells both of which causes non-absorption or usage of glucose when the person eats foods with glucose. This will leave the blood with increased amounts of glucose that will affect the functioning of many vital organs in the body.
What is the disorder in which cells are unable to obtain glucose from the blood such that high blood-glucose levels result?
Diabetes is what you're asking for. However, it is not the bodys inability to obtain glucose from the blood. It is the inability of the pancreas to secrete insulin to help control the amount of glucose in the body.
What body systems do diabetes affect?
In the pancreas, a leaf-shaped organ near the duodenoum, there are special cells called the Islets of Langherhans, of which there are 4 types, the A cells secrete a hormone Glucagon which raises the blood glucose level . The B cells produce the hormone Insulin which lowers blood glucose level. The interaction of these two hormones regulates the blood glucose level.
How does diabetes affect the organism?
well basically Diabetes effect our pancreas which either doesn't make enough insulin or no insulin. Insulin is needed for our cells to utilize glucose for energy. It is required for the glucose to enter into the cell. No insulin means the glucose stays in your bloodstream, which can cause many problems including death if not treated.
What is the hormone that causes a decrease in blood glucose?
Insulin is released by the pancreas and enters the blood, delivering glucose into cells for use (therefore lowering your blood glucose level). In some cases, like in a person with diabetes, glucagon is released and lowers blood glucose levels.
What type of diabetes increases blood level?
Both type 1 and type 2 diabetes can lead to increased blood glucose levels. In type 1 diabetes, the body does not produce insulin, a hormone necessary for glucose uptake by cells. In type 2 diabetes, the body either becomes resistant to insulin or does not produce enough insulin to maintain normal glucose levels. This results in elevated blood sugar levels in both types of diabetes.
How does the pancreas control blood glucose levels?
Blood levels of glucagon and insulin are controlled by islets of Langerhans in the pancreas, in which some of the islet cells, called alpha cells, secrete the hormone glucagon and other islet cells, called beta cells, secret insulin.
Why can hydrochlorothiazide reduce glucose tolerance?
Hydrochlorothiazide inhibits islet beta cells releasing insulin. Such can increase the blood glucose and reduce glucose tolerance, resulting in aggravating diabetes. So it is rather serious to use this medicine on patients with hypertension and diabetes.
What foods lower my blood sugar?
Lowering your blood sugar is important to avoid pre-diabetes, diabetes, insulin resistance and overweight issues. Lowering your blood sugar naturally keeps your health vital and strong. Here's how it works: You eat something and the stomach and intestines breaks the food down into glucose. The cells need glucose for energy, but for the cells to be able to use glucose they also need insulin which the pancreas emits in the response to glucose.
What goes on in the patients body during diabetes?
Diabetes (diabetes mellitus) is classed as a metabolism disorder. Metabolism refers to the way our bodies use digested food for energy and growth. Most of what we eat is broken down into glucose. Glucose is a form of sugar in the blood - it is the principal source of fuel for our bodies. When our food is digested the glucose makes its way into our bloodstream. Our cells use the glucose for energy and growth. However, glucose cannot enter our cells without insulin being present - insulin makes it possible for our cells to take in the glucose. Insulin is a hormone that is produced by the pancreas. After eating, the pancreas automatically releases an adequate quantity of insulin to move the glucose present in our blood into the cells, and lowers the blood sugar level. A person with diabetes has a condition in which the quantity of glucose in the blood is too elevated (hyperglycemia). This is because the body either does not produce enough insulin, produces no insulin, or has cells that do not respond properly to the insulin the pancreas produces. This results in too much glucose building up in the blood. This excess blood glucose eventually passes out of the body in urine. So, even though the blood has plenty of glucose, the cells are not getting it for their essential energy and growth requirements. thank you for your time- Vertigo1234554321 signing out
Why blood glucose levels are controlled in people who do not have diabetes?
Because the disease "Diabetes" kills the cells in the pancreas that release the hormones that control blood sugar levels. Therefore healthy people are fine.
