## Aqa B3 Homeostasis Glucose

I used eight printed in colour and laminated sets of the work mat and asked the students to use whiteboards to explain what is happening in each stage, I then got them to construct a negative feedback loop using their own notes then checking it against the ones shown in the power point. We finished off with diabetes and the exam questions. A busy lesson! Feedback appreciated. Read more Continue reading >>

##### low blood sugar before meals

i'm not sure how to handle this, and it's happened a few times. >_<
when i test low before a meal should i treat it a little and eat my food as normal? (insulin and all.) or should i NOT treat and just go straight for the meal w/insulin, trusting that it will rise enough to be safe again?
i've been treating a little just so my hands will stop shaking, but i'm nervous about dropping even lower once i take insulin.
what do you do?

I have a pump so I will tell you what I do when I am low before a meal. I calculate my carbs, figure out the appropriate insulin, and then take back the amount of insulin for the low. For example, if my blood sugar is 3.9 (69) and I want it at 5.9 (105) and I have eaten 40 grams of carb my calculation will be as follows:
2 units for the 40 grams of carb (1:20 insulin ratio)
minus the one unit that would have taken me from 105 to 69 - so I would take only 1 unit of insulin for the food I had eaten.
I hope that makes sense.

I am not on the pump. If I am under 100 before a meal, I will eat the meal, then dose accordingly. If I'm - let's say in the 90's, I'll start eating, then dose. If I'm in the 60's to 70's, I'll eat the whole meal, then dose. This works for me.

Diabetes is a very common disease, which, if not treated, can be very dangerous. There are two types of diabetes. They were once called juvenile-onset diabetes and adult diabetes. However, today we know that all ages can get both types so they are simply called type 1 and type 2 diabetes. Type 1, which occurs in approximately 10 percent of all cases, is an autoimmune disease in which the immune system, by mistake, attacks its own insulin-producin ...

• Relationship Between Insulin And Glucose Diagram

Your body uses glucose for energy. Glucose metabolism requires insulin, a hormone produced by your pancreas. Here's how normal glucose metabolism works, and what happens when you have diabetes — a disease where your body either can't produce enough insulin or it can't use insulin properly. The food you eat consists of three basic nutrients: carbohydrates, protein and fat. During digestion, chemicals in your stomach break down carbohydrates into ...

• Type 1 And Type 2 Diabetes Venn Diagram

In general, people with diabetes either have a total lack of insulin (type 1 diabetes) or they have too little insulin or cannot use insulin effectively (type 2 diabetes). Type 1 diabetes (formerly called juvenile-onset or insulin-dependent diabetes), accounts for 5 to 10 out of 100 people who have diabetes. In type 1 diabetes, the body's immune system destroys the cells that release insulin, eventually eliminating insulin production from the bod ...

Insulin is a hormone that helps cells use glucose (sugar) for energy. It works as a “key,” allowing the sugar to go from the blood and into the cell. In type 1 diabetes, the body doesn’t make insulin. In type 2 diabetes, the body doesn’t use insulin correctly, which can lead to the pancreas not being able to produce enough — or any, depending on the progression of the disease —insulin to meet your body’s needs. Diabetes is normally ...

Regardless of large fluctuations in physical activity and food intake, blood sugar levels are held within very narrow limits. The key to this is insulin, the secretion of which is closely regulated by circulating substrates of energy metabolism. Insulin signa ...
