The skin around my neck is really dark, and I was told by a doctor that its acanthosis nigricans. He gave me some medicine and cream, but they haven't helped much. My sugar and thyroid levels are normal, but Ive gained some weight recently (Im 5'11" and 85 kg). Can you help me understand why this is happening and what I can do to get rid of it?

Acanthosis nigricans (AN) is a skin condition characterized by dark, velvety skin patches, typically on the neck, armpits, elbows, knees, or knuckles.Possible Reasons:1. Insulin Resistance: Although your sugar levels are normal, insulin resistance can still contribute to AN. As you're overweight, this could be a factor.2. Hormonal Imbalance: While your thyroid levels are normal, other hormonal imbalances, such as polycystic ovary syndrome (PCOS), can contribute to AN.3. Genetics: AN can run in families, so there might be a genetic component.4. Obesity: Your weight could be contributing to the development of AN.Getting Rid of Acanthosis Nigricans:1. Weight Loss: Losing weight, particularly around the abdominal area, can help improve insulin sensitivity and reduce AN symptoms. Aim for a healthy weight (around 70-75 kg for your height).2. Dietary Changes: Focus on whole, unprocessed foods like vegetables, fruits, whole grains, lean proteins, and healthy fats. Avoid sugary drinks and foods high in saturated fats.3. Exercise Regularly: Engage in moderate-intensity exercise, such as brisk walking, cycling, or swimming, for at least 150 minutes per week.4. Topical Treatments: Your doctor may prescribe topical creams or ointments containing ingredients like retinoids, hydroquinone, or urea to help lighten the skin.5. Medications: If your doctor suspects insulin resistance or hormonal imbalances, they may prescribe medications to address these underlying conditions.Consult Your Doctor:It's essential to follow up with your doctor to discuss the following:1. Medication adjustment: Your doctor may need to adjust your medication or add new ones to address the underlying causes.2. Lifestyle modifications: Your doctor can provide personalized guidance on weight loss, diet, and exercise.3. Monitoring: Regular check-ups will help your doctor monitor your progress and adjust your treatment plan as needed.
