Remember, diabetes is where people have a disease where they cannot control their blood sugar levels very well. So it's an example of where homeostasis is not working. Homeostasis is where we control our internal environment.
Is it important that you control your sugar levels? Yes it is!!!
Low blood sugar levels can cause unconsciousness.
High blood sugar levels can damage organs such as your eyes.
There are 2 different types of diabetes and you must learn the differences.
Type 1 diabetes
This is where the pancreas does not make insulin. This means that when they eat something and their sugar levels rise then there is nothing to tell the liver to remove excess glucose. So, people with Type 1 diabetes usually inject insulin every day. The insulin has to be injected into the fat layer just beneath the skin - this is called the subcutaneous fat layer. Fat easily absorbs the insulin where it then spreads into the blood capillaries and is carried around the body to the liver in the blood stream.
Type 2 diabetes
Type 2 diabetes happens when the cells in a persons body respond less well to insulin - the cells start to become 'resistant' to insulin even though the pancreas is still making the hormone. Doctors have worked out the many reasons that can cause type 2 diabetes like being obese, lack of exercise, getting older and having a high fat diet.
Type 2 diabetes can often be controlled by changing:
1) their diet - eating less fat and glucose.
2) increasing their exercise to use up excess glucose through respiration.
