Blood Glucose Agents Flashcards
(170 cards)
1
Q
What is Adiponectin?
A
Hormone that increases insulin sensitivity, decreases glucose release from the liver and protects blood vessels from inflammation.
2
Q
Explain Diabetes mellitus.
A
Chronic condition characterized by higher blood sugar levels due to either insufficient insulin production or the body’s inability to effectively use insulin.
3
Q
What is Dipeptidyl-peptidase-4 (DPP-4) ?
A
Enzyme that breaks down incretin hormones which helps regulate blood sugar levels by stimulating insulin release after eating. DDP-4 inhibitors prevents DDP-4 from breaking down incretin, allowing it to work for longer
4
Q
What are the Endocannabinoid receptors?
A
Receptors part of Endocannabinoid system. Involved in regulating appetite, mood and metabolism.
5
Q
What is Glucagon - like polypeptide - 1 (GLP-1) ?

Hormone released from intestines that help regulate insulin secretion, glucose metabolism and appetite.
6
Q
What is Glycogen?
A
Stored form of glucose found in the liver and muscles and used by the body for enegy when blood sugar is low.
7
Q
What is Glycosuria?
A
Excess glucose in the urine. Sugar is spilled into the urine and is an indication of poorly managed diabetes.
8
Q

Hemoglobin bound to glucose - used to measure long term blood sugar control. (A1C)
9
Q
What is Hyperglycemia?
A
Increased blood sugar levels (over 126)
10
Q
What is Hypoglycemia?
A
Low blood sugar levels (under 70)
11
Q
What are Incretins?
A
Hormones (GLP 1) that are released by the gut after eating to enhance insulin secretion and help regulate blood glucose.
12
Q
What is Insulin?
A
Hormone produced by pancreas that help regulate blood glucose levels by promoting glucose uptake into cells for energy.
13
Q
What is Ketosis?
A
Metabolic state where body produces ketones for energy due to lack of sufficient glucose - seen in uncontrolled diabetes or starvation.
14
Q

16
Q
What is Sulfonylureas?
A
Class of oral medication used to treat type 2 diabetes by stimulating the pancreas to produce more insulin.
17
Q
Which gland produces Insulin?
A
The Pancreas in the endocrine part.
18
Q
Where in the Pancreas is insulin produced?
A
The islets of Langerhans (by beta cells)
19
Q
Is the Pancreas an endocrine or exocrine gland?
A
It is both.
20
Q
What does the exocrine part of the Pancreas do?
A
- Releases sodium bicarbonate and pancreatic enzymes directly into the common bile
duct to be released into the small intestine. - Neutralizes the acid chyme from the stomach and aids digestion.
21
Q
What is the dual function of the pancreas important for?
A
Metabolic regulation and proper digestion.
22
Q
When is Insulin released into circulation?
A
When levels of glucose around the Islet of Langerhans cells rise. (usually after eating)
23
Q
When does the pancreas release glucagon?
A
When blood glucose levels are low. This signals the liver to break down stored glycogen into glucose and release it into the bloodstream.
24
Q
What does insulin do?
A
Stimulates glycogen synthesis conversion of lipids into fat stored
as adipose tissue, and synthesis of proteins from amino acids.
25
What does insulin ensure?
That blood glucose does not get too high or too low.
26
Why is insulin released after a meal?
So that the blood glucose levels can fall.
27
Where is Glucagon released from?
The alpha cells into the islets of Langerhans
28
What is Glucagon released in response to?
Low blood glucose
29
What does Glucagon do?
Causes immediate mobilization of glycogen stored in the liver and raises blood glucose levels. It does the opposite of insulin.
30
What does Adipocytes secrete?
Adiponectin
31
What does adiponectin do?
Increases insulin sensitivity, decreases release of glucose from liver, and protects blood vessels
from inflammation.
32
What does Endocannabinoid receptors do in the body?
Keeps the body in a state of energy gain to prepare for stressful situations
33
Which nervous system decreases insulin release?
The sympathetic nervous system.
It also increases release of stored glucose and increases fat breakdown.
34
What effect does epinephrine have on blood glucose?
Increases glucose levels in the blood so that the body has energy to face the threat or run away from it.
35
What does Corticosteroids reduce?
Insulin sensitivity.
36
What does Corticosteroids increase?
The release of stored glucose and fat breakdown for immediate use during stress.
37
What does growth hormone decrease?
Insulin sensitivity
38
What does growth hormone increase?
Free fatty acids and protein building.
39
Why does Glycosuria occur with unmanaged Diabetes?
Due to abnormally high blood sugar the body cannot absorb it all and it spills out in the urine. Urine may appear frothy.
40
What can glucose in the urine lead to?
Cystitis, due to glucose allow bacteria to thrive.
41
What is Polyuria?
Increased urination. This happens because the glucose in the urine pulls more water from the body into the nephrons of the kidney.
42
Why does polydipsia occur with unmanaged diabetes?
Due to more water being excreted in urine due to the high glucose level, the hypothalamic cells signal that the body needs more water and this causes excessive thirst.
43
Why does polyphagia occur with unmanaged diabetes?
The body cannot use the glucose that is available. This causes fatigue and the body thinks that it is starving and so it signals to the person to eat more.
44
Why is Lipolysis activated with unmanaged diabetes?
The body thinks that there is no energy or glucose, and therefore initiates lipolysis which uses fat as energy. The body goes into ketosis because of the use of fat as energy.
45
Why does acidosis occur with unmanaged diabetes?
The ketones that are a result from lipolysis cannot be cleared from the body and muscles starts to be broken down for energy and a state of acidosis begins because the waste products of ketones, proteins and glucose are acidic. This leads to elevated BUN and protein in urine.
46
What is Diabetes Mellitus?
Chronic condition where the body have difficulty in breaking down blood sugar.
The body may not produce enough insulin (type 1)
Body gotten resistant to insulin effect (type 2)

Can cause loss of vision as tiny vessels in the eye are narrowed and closed
56
Explain Neuropathies.
Affect nerves in the feet and legs and progressive changes in other nerves as the oxygen is cut off. This causes motor and sensory changes as well & foot ulcers are common and poor circulation and nerve damage lead to decreased wound healing and decreased ability to feel pain, which makes it harder to detect infection.
57
Explain Nephropathy.
Damage to the glomerulus impairs the kidneys ability to filter blood and infections become more frequent due to reduced blood flow and immune function.
58
Explain Infections r/t diabetes
Increases in frequency and severity due to decreased blood flow and altered neutrophil function
