While most people with prediabetes show no signs or symptoms, some people may experience a condition called acanthosis nigricans, which is darkened skin on certain parts of the body, according to Mayo Clinic. The most commonly affected parts of the body include the knees, knuckles, elbows, armpits and neck.
Prediabetes is a condition in which a person has elevated blood sugar, but it is not high enough to be classified as Type 2 diabetes, states WebMD. Treating the condition as soon as possible helps prevent many complications, such as kidney damage or heart and blood vessel damage, and may halt the progression to full-stage Type 2 diabetes.
The best way to treat prediabetes is to make healthy lifestyle choices, according to Mayo Clinic. One way to do that is to start eating a healthier diet. Patients should focus on adding foods that are high in fiber and low in calories and fat. Adding more fruits, vegetables and whole grains is a good way to start this kind of diet. Getting more physical activity is another positive lifestyle change a person can make. Patients should exercise for at least a half hour on most days. This includes taking a brisk walk, going biking or swimming, or performing resistance training.
