Acanthosis nigricans is the primary symptom of borderline diabetes, a condition characterized by darkened skin on body parts such as the neck, knees, knuckles and armpits. Others symptoms include frequent urination, fatigue, increased thirst and blurred vision, according to Mayo Clinic.
Borderline diabetes occurs when the blood sugar level becomes higher than normal, and without medical attention, it can result in Type 2 diabetes. It occurs when the body produced insulin in insufficient amounts or does not use the available insulin properly, making sugar to accumulate in the bloodstream. Its exact cause is unknown, but researchers state that it is related to genetics and family history, reports Mayo Clinic. This condition can increase the risk for cardiovascular disease, says Healthline.
Symptoms of borderline diabetes are an opportunity for a patient to seek medical care early in advance to reduce chances of developing Type 2 diabetes in the future. Also, it is advisable for patients with risk factors such as a family history of Type 2 diabetes, being overweight, hypertension and polycystic ovary syndrome to seek blood glucose screening, states Mayo Clinic. They should also eat healthily such as whole grains, vegetables and meals low in fat protein, and limit calories and sugars. Moderate exercises such as swimming and cycling are also essential, notes WebMD.
