2. Rapid weight loss
Very high blood glucose levels can also trigger rapid weight loss in individuals. Typically the weight loss may seem unexplainable and too rapid to be considered healthy. The reason behind this is that since the capacity of insulin to get glucose into the cells has been impaired, it cannot be stored in the body as energy. This results in the body thinking that it is in starvation mode making it rely on protein from the muscles as an alternate energy source.
At the same time, the kidneys are also working overtime to eliminate excess sugar with the combined result that there is a rapid loss of calories from the body.
