if someone has diabetes, why do they avoid sugar?

Question

This is a honest question, and I do not mean any disrespect to anyone. I am just trying to get my mind around this condidtion.
(type 2 - non insulin dependant)
So, if their body cannot process sugar fully, then why do they avoid it.
surely any excess sugar - not used by the body would just be excreted?
and why avoid sugar, yet, if the person starts to feel faint, you give them a sugary drink or piece of candy?

Answer 1

If the body is not processing sugar properly, ie. the pancreas is not producing enough insulin/person is insulin resistant

(ie. on eating sugar the pancreas produces insulin in order to convert the glucose into the storage molecule glycogen or use it for metabolic processes. In the insulin resistant person the sugar triggers the production of insulin, but the insulin does not convert the sugar therefore the brain continues to detect more sugar in the blood and pancreas produces more insulin. This overworks the pancreas and therefore damages it and its insulin production..
.. the other effect of eating sugar for a type two diabetic is the fact that if the insulin cannot convert the sugar to a usable form by the body then the body will not use it but store it as fat.. the person will be sluggish and have no energy even though they have eaten a lot of sugar.

This is why eating slow release carbs low gi foods is beneficial it does not overload the body and send it into chaos. This is hyperglycemia (too much glucose in the blood).

Hypoglycaemia is the opposite where there is not enough sugar in the blood and we can all get this.. It is when we feel faint/dizzy from not eating. Because diabetics are very sensitive to sugar and their endocrine system is in dissaray a lot of the time this can happen more often. It is important that diabetics eat little and often to combat this problem. Also eating the right things (low gi foods and slow release carbs) as eating very sugary foods can cause a crash after the initial sugar high which triggers the hypoglaecemia

Hi Futurama
The pancreas is an organ situated in the area of the diaphragm which secretes a hormone called insulin. Insulin processes carbohydrates into glucose and it is then used by the body to provide energy. Excess glucose is not excreted but stored in the liver and muscles as fat. In type 1 diabetes the pancreas produces little, or no insulin therefore you have to inject it is normally these people that faint rather than people with type 2. It is called a hypoglycemic coma. In type 2 the pancreas doesn't produce enough insulin to process the carbs, so it is controllable by diet eg. Reducing your carb intake. As for your last question it is because the glucose level in the blood has dropped to a very low level and the brain cannot function properly. As I said that normally only happens to insulin dependant type 1 diabetics.

This is a pretty large question. Let's see if I can shed some light on it...
Type 2 diabetes is a disease in which your body can not properly utilize the sugars you eat. A normal body will use insulin and the sugars you eat to create energy. If you have Type 2 diabetes, your bodys insulin isn't taking up the sugar, and your organs begin to create their own forms of energy. This puts your organs into "overtime" so to speak... creating forms of energy called ketones, which raise your bodys acidity. Your eyes, nerves, heart and kidneys can all be detrimentally effected. Therefore, for a person w/ Type 2, they have to make sure to limit their sugars in small doses, or they will have too much in their blood, too little in their system. That is called ketoacidosis.
Now, when you speak of someone feeling faint, and you give them candy, you are talking about someone with Type 1 diabetes. Type 1 diabetics don't produce insulin, so they have to inject it. When they have too much insulin in their blood, they can begin to "feel faint" as you said, and giving them sugar orally is the best way to balance that insulin out in their blood.

I didn't do the best job of explaining all of this... but I tried. It's a pretty loaded question. Visit the ADA website if you are interested in knowing more.

I'm a 45 year old woman and was recently diagnosed as being a borderline diabetic. My doctor prescribed some medication, but before filling it I decided to do some research on the internet which led me to the methods. After reading this ebook and applying the methods, my scepticism turned to 100% belief. I noticed that my energy levels increased significantly and I felt more rested in the morning, my symptoms started going away.

I am very happy to tell you that I have been feeling better than I have felt in years and my doctor informed me that he will be taking me off my prescriptions if I keep this up.

I recommend you use the Type 2 Diabetes Destroyer to naturally reverse your diabetes.

Hi! I am a type one diabetic, and it's not the sugar we try to avoid per se, it's excessive carbohydrates. If you look at the carbohydrate content of a full-size Snicker's bar, it's through the roof. Same goes for regular soda and anything that has refined sugar. Most diabetics can process sugar in moderation just fine, it's the carbohydrates we have to be worried about.

I take two to three shots of insulin a day, and have been diabetic for 14 years. I don't avoid anything, and my control is really good. I know when I go overboard and when I'm okay. Pizza is a food that has the most carbohydrates, so when I eat it, I have to take more insulin to cover myself.

Many common natural remedies are claimed to have blood sugar lowering properties that make them useful for people with or at high risk of diabetes. Learn here https://tr.im/W89qR

A number of clinical studies have been carried out in recent years that show potential links between herbal therapies and improved blood glucose control, which has led to an increase in people with diabetes using these more 'natural' ingredients to help manage their condition.

Answer 9

Diabetes in complex subject , even endocrinologist are still learning how it effects various organs and how to prevent damage, As regards to ur question, when there is excess sugar circulating in your bloods, your kidney's start passing it in your urine, to do so it has to pass large amount of water as well, that's why polyuria(passing too much urine) and polydipsia( too thirsty) are common symptoms of uncontrolled diabetes, there is real danger of giving sugar to someone who is already dehydrated as it will cause him to excrete more urine and get even worse. There is already excess of sugar in body but real problems in Type 2 is that they cant utilise it as fuel and they have to rely to body's reserve energy which leads to large amount of ketones, the whole scenario if not corrected can finally lead to coma, ketotic coma, which fortunately is rare nowadays in western world because of patient education,but Type 1 pt risks suffering from hypoglycemia, which f not treated can be dangerous as well, If in doubt always give sweet to diabetic as it may save life

Answer 10

from what I can understand from my doctor..my pancreas does not supply insulin to my body like it should. I take pills. Your pancreas helps in the digestion of foods. When you eat sugar you diminish your pancreas' ability to deal with the sugar and the food...eventually you will have diabetic neuropothy..when the blood vessels become tiny and restricted..the blood flow is insufficient to work your organs, you eyes can go blind..you could lose your feet and legs..your kidneys shut down..and your brain and heart suffer emensly...watch what you eat...low carbs, no white sugar, little caffine, little fried foods, little or no alcohol.
