If you have diabetes do you feel weak if you dont have enough sugar in your blood?

Answer 1

The only time that a diabetic person loses alot of weight (becomes thin) and feels weak because of the Diabetes itself is when the blood sugar is very high. This can be either before diagnosis (in fact this is a prime Why_do_diabetics_become_thin_and_feel_very_weak) or when there is not enough insulin in the body. Many type one teenage diabetics will deliberately omit the insulin for weight loss.

hope this did not help

Answer 2

I can't see any other answers to this question although I'm sure there are many. I apologise for repeating if that is so.

The only time that a diabetic person loses alot of weight (becomes thin) and feels weak because of the diabetes itself is when the blood sugar is very high. This can be either before diagnosis (in fact this is a prime symptom) or when there is not enough insulin in the body. Many type one teenage diabetics will deliberately omit the insulin for weight loss.

In layman's language, insulin makes the cells "open up" to withdraw the glucose from the blood. Thus, now can begin the digestion process.

When there is not adequate insulin the glucose remains in the blood and the body can not use the food for energy. Instead it uses fat. This is where weight loss begins.. The immediate danger of this is that the breaking down of body fat creates a by product of ketones. When there are large amounts of ketones in the body it can lead to DKA.

As regard for feeling very weak, when the sugar is very high the body cannot function properly (as explained above, the food is not digested, more prone to infections etc) Think of it logically - if you have a coffee with 10 tablespoons of sugar, how will that make you feel?? It's no different with sugar in the blood.

Answer 3

Yes and no. Our bodies need glucose for energy, and without it we will indeed be very weak, tired and unable to think clearly. (Our brain needs a lot of energy too.) If you have diabetes, your cells are not able to use the sugar in your blood for energy because you lack the insulin to allow the glucose to get through the cell membrane. Think of insulin as the key you use to get into your house. No key, no enterance regardless of how much sugar is kicking around. However, if there is no sugar (glucose) in the blood stream, all the insulin in the world can't help out. In fact, too much insulin can be deadly because it uses up what little glucose there is too quickly.
