1. Palpitations or fast heart rate

"Low blood sugar levels can lead to a racing heart or heart palpitations," Dix explains.

2. Shivering and sweating

Dr. Dix says that “when a person is shaking or sweating, they should review the contents of their food intake, because some, such as simple carbohydrates, are easily digested and absorbed causing blood sugar levels to rise rapidly and then drop rapidly in a kind of crash. But by adding protein and healthy fats to meals and choosing whole grain carbohydrates, which break down more slowly, it is likely that blood glucose levels can be kept in check.”

3. Extreme hunger and irritability

“When the stomach is empty, there will not be enough fuel to run the body,” Dr. Dix explains. One can literally feel as if they are lying in their bed rather than sitting at their desk. The key is to eat a balanced meal with the golden trio of protein, whole grain carbs, and healthy fats.”

4. Dizziness and weakness

"Sugar feeds the brain," adds Dix. Obviously, too much sugar can have a negative effect as well, but when a person is not eating or when they are not eating in a healthy way, they can feel dizzy and weak.”

5. Anxiety and panic

Interestingly, according to Dr. Dix, “Some of the signs and symptoms of low blood sugar are similar to those of an anxiety attack or a stressful state. When someone feels that they are starting to feel weak or dizzy, they fear that their blood sugar levels will drop to dangerous levels. The feeling can cause a panic attack and anxiety.”
