5. Blurred Vision
High glucose levels in the blood can cause the eye and the lens to swell, changing the shape of the lens, leading to blurred vision. If checked, this can be corrected. If left unchecked, it can lead to more serious and permanent problems like blindness.
6. Yeast Infections
Fungi and bacteria love sugar. Glucose is sugar, so high levels foster fungi. One of the most common fungal reactions to diabetes is yeast infections. Affecting both men and women, yeast infections feed on glucose and grow between fingers and toes, in and around the sexual organs and under breasts.
