DIABETES MELLITUS Flashcards
a metabolic disorder characterized by glucose intolerance, caused by an imbalance between insulin supply and insulin demand.
DIABETES MELLITUS
the body is not tolerating the increased amount of glucose in the blood because there is no insulin that will be able to metabolize the glucose
GLUCOSE INTOLERANCE
Also referred as insulin dependent diabetes mellitus
TYPE 1
Juvenile onset and is characterized as destruction of beta cell by autoimmune responses, Hereditary predisposition (human leukocyte antigen), and toxin and virus
TYPE 1
Type of diabetes wherein there is little or absence of insulin
TYPE 1
Also referred to is non insulin dependent diabetes mellitus
TYPE 2
Adult onset and is characterized by insulin resistance due to obesity, hereditary predisposition, and environmental factors (toxins and virus)
TYPE 2
Occurs in 2nd to 3rd trimester and due to hormone released during pregnancy (human placental lactogen)

Explain the Differences between DM 1 and DM 2.
Type 1 DM or Juvenile onset DM is a form of DM that is dependent on insulin. The primary problem in this type of diabetes is the destruction of beta cell which is responsible for insulin production. Since beta cell are damage, there will be lack or no insulin at all present in this patient. Without insulin, the body will not be able to metabolize glucose or let it enter the cell, leading to increasing amount of glucose in the blood stream or HYPERGLYCEMIA. This is commonly associated with autoimmune response wherein the body immune cells mistakenly attack the pancreas or beta cell.
On the other hand, DM 2 also known as Adult onset DM is non insulin dependent . The main problem of this kind type of Diabetes is Insulin resistance, wherein cells are not just receptive to insulin. Because of this, there will be no glucose uptake or metabolism leading to increasing amount of glucose in the blood stream or HYPERGLYCEMIA). This is commonly associated with lifestyle factors such as obesity and sedentary lifestyle.
Explain the differences between DKA and HHNS
Diabetic KetoAcidosis is a complication of type 1 DM. Its hallmarks includes
1). HYPERGLYCEMIA (300-800 mg/dL) due to decrease glucose uptake or metabolism associated with lack of insulin
2). KETOSIS due to fat breakdown or lipolysis associated with cell starvation and compensatory mechanism of our body for energy needs
3). ACIDOSIS due to the presence of ketones in the blood, which is acidic.
Hyperglycemic Huperosmolar Nonketotic Coma is a complication of type 2 DM and is characterized by
1). HYPERGLYCEMIA (600-2000 mg/dL) due to decrease glucose uptake or metabolism associated with insulin resistance
2). HYPEROSMOLARITY due to increase blood glucose level (600-2000 mg/dL)
3). PROFOUND DEHYDRATION due to osmotic diuresis associated with hyperosmolarity. The super increased blood glucose level moves fluid from the interstitial and cells into the vessels (Highly concentrated) leading to it being excreted along with excess glucose)
