One prominent symptom of low blood glucose is shakiness or tremors. As glucose is the primary energy source for the body (and brain), a drop in blood glucose levels can lead to a rapid depletion of energy, resulting in an overall sense of shakiness and weakness.

Sweating may also be experienced and accompanied by feelings of anxiety or nervousness, due to the body releasing the stress hormones adrenaline and cortisol which trigger the classic "fight or flight" response.

Your brain relies significantly on glucose for optimal function so, if blood glucose levels are running low, you might start to feel confused or unable to concentrate. You might also notice that food thoughts start to increase and you feel more out of control and scared around food choices.
