Feeling Irritable
Another sign of undiagnosed diabetes is constantly feeling irritable. This symptom is often misdiagnosed as resulting from stress or changes in personality. If a person’s blood sugar drops too low, their brains don’t receive the glucose they require to function properly. This can lead to feelings of irritability and anxiety, or even sometimes anger. Luckily, it is possible to reverse this symptom. As the individual’s blood sugar levels become better controlled through medication or lifestyle changes, emotional balance usually returns, improving their overall sense of well-being.
