Carbohydrates And Blood Sugar

When people eat a food containing carbohydrates, the digestive system breaks down the digestible ones into sugar, which enters the blood. As blood sugar levels rise, the pancreas produces insulin, a hormone that prompts cells to absorb blood sugar for energy or storage. As cells absorb blood sugar, levels in the bloodstream begin to fall. When this happens, the pancreas start making glucagon, a hormone that signals the liver to start releasing stored sugar. This interplay of insulin and glucagon ensure that cells throughout the body, and especially in the brain, have a steady supply of blood sugar. Carbohydrate metabolism is important in the development of type 2 diabetes, which occurs when the body can’t make enough insulin or can’t properly use the insulin it makes. Type 2 diabetes usually develops gradually over a number of years, beginning when muscle and other cells stop responding to insulin. This condition, known as insulin resistance, causes blood sugar and insulin levels to stay high long after eating. Over time, the heavy demands made on the insulin-making cells wears them out, and insulin production eventually stops. Glycemic index In the past, carbohydrates were com Continue reading >>

    Can insulin raise blood sugar

    I have just recently been diagnosed. My morning blood sugars have always been between 5.6 - 6.0 and i was told these where too high and they should be lower than 5.3. I was started on Insulatard and that has gradually been increased to 16 units at bedtime only. Last night before bed my blood sugar was 6.1, This morning it was 6.9 ! I don't understand this at all, when i mention it to my diabetic team all they suggest is increasing by another 2 units. Surely after 16 units of insulin last night my blood sugar should have went down and not up ! I am getting so frustrated ! Is it possible the insulin is doing more harm than good ?

    Definatly not. INsulin breaks down the sugar in you body and converts it in to energy. As for a small rise over night, I have been told as long as it stay within a range of two mmol throughout the day its fine. Its a known fact that you liver dumps sugar in your system over night, so that would explain you rise.

    Insulin is like the key to a lock in your body. It allows your cells to take in glucose. Without it the gluc stays in your blood and your body 'thinks' it is starving (one reason appetite tends to go up, yet you loose wt as a symptom of the condition)
    There is a something called the "Somogyi effect." This is a natural way for your body to react to a low blood glucose. When you get a low BG your body uses a hormone called glucagon to raise it. It involves release of sugars from your liver. This is a safety mechanism for the body; but much slower reacting than insulin release from your pancreas.
    It could be your BG dropped quite a bit during the night and your body reacted with the above; however, the over-swing is usually quite marked. Sometimes your body wakes you up during the night if your BG drops low (not always though). I would approach your diabetic team again as increasing the insulin may not be the way fwd.
    Out of interest, and tell me to bugger off it too personal, but how much do you weigh? I know in vetmed we usually aim for 1/2IU per Kg BW (acc to my endocrinologist its much the same for humans). However, this does vary with sensitivity to insulin.

  • Does Insulin Increase Blood Glucose

    Most cells in the human body use the sugar called glucose as their major source of energy. Glucose molecules are broken down within cells in order to produce adenosine triphosphate (ATP) molecules, energy-rich molecules that power numerous cellular processes. Glucose molecules are delivered to cells by the circulating blood and therefore, to ensure a constant supply of glucose to cells, it is essential that blood glucose levels be maintained at r ...

  • How Does Glucagon Increase Blood Glucose Levels?

    Changes in your blood sugar levels can affect how you feel. To help you keep the level steady and healthy, your body makes a hormone called glucagon while you sleep and after you eat. It's made in your pancreas, a small organ above your liver, and it can raise levels of glucose, or sugar, in your blood. That's the fuel your muscles and organs use to work and stay healthy. Glucagon helps your liver break down the food you eat to make glucose. If y ...

    There are several factors at work to lead you to believe that insulin is "to blame" for your weight gain. People who have poorly controlled diabetes also sometimes experience weight loss because their bodies are unable to properly convert food into energy. This is because they either are not producing enough insulin or their bodies are unable to use the insulin they produce properly. This food winds up as excess glucose circulating in the blood ( ...
