The thrifty gene theory is a theory about diabetes being formed in a faulty gene during pregnancy. This abnormality would grant a small but useful metabolic advantage upon heterozygote carriers of the gene, but would produce juvenile diabetes a lethal trait …show more content…

Insulin resistance is when the body can not properly respond to the hormone insulin. Because of the lack of insulin to let in glucose, glucose levels rises in the blood stream. When this happens the pancreas, in charge of making insulin, produces more insulin to let the sugar get into the cells. Because of the great amount of insulin in the body, it lets all the glucose in the bloodstream reach the necessary areas.Glucose levels in the blood then drop very low, sending a signal to us making us want to eat which also signals the body to lower the amount of insulin produced. Type 2 diabetes is a by product of what happens when your body becomes insulin resistant. Type 2 diabetes are mostly given though genetics. this diabetes is caused by a combination of environment and genetic factors e.g. obesity, high bp, high cholesterol and physical inactivity. The cell tissues of the liver, muscle and …show more content…

It is the most common type of diabetes with 90-95% of the cases of diabetes resulting in type 2. Type 2 diabetes causes the the pancreas to create too much insulin which causes insulin resistance. Because of insulin resistance the levels of sugar in the bloodstream rises and causes the red blood cells to become coarse which damages the circulatory system. The thrifty gene theory is metabolic abnormality that creates juvenile diabetes in the feotus. it was theorised to be traced back to homo sapiens whom starved during famines. Also that obesity is becoming more of a health issue and is causing more cases of Type 2

    Insulin is a hormone that is made in the pancreas and is essential for us to live. It controls carbohydrates and fat in our bodies, which we consume through the food we eat. For example, glucose is taken up by the liver and adipose tissue to create energy for cells, glucose can also be converted into fat to provide energy when glucose levels are low. Insulin is controlled by when a lot of glucose has been absorbed into our bloodstream, the rise in blood glucose cause the pancreas to release more insulin. Once blood glucose levels return back to normal, the insulin that is being released will slow down.

While the genetic risk factor for diabetes is not the sole determining factor in whether or not an individual develops diabetes, a pattern can be seen in the genogram and R.O. should be made aware of his increased risk due to his genetic makeup. Hypertension can also be seen in his genogram when looking at his paternal grandmother, father, and maternal aunt, Lela Mae. Again, the genetic risk factor is not the sole risk factor, but R.O. should be made aware of this risk factor so he can change his modifiable risk factors, such as BMI greater than 30, and be monitored for the development of

    Type 2 diabetes is usually caused by unhealthy physical activity habits or genetics, as those who are not physically active, overweight, or have family members with diabetes are at a high risk for developing type 2 at some point in their lives. Having excessive weight, especially around the stomach, can sometimes cause the insulin being produced by the pancreas to not be used as effectively as it could be. Gestational diabetes sometimes develops during pregnancy, and though it is unknown exactly why it develops, many scientists believe it could be due to hormonal changes. The extra weight gained during pregnancy also could be a factor.
