What Does Having A Black Neck Mean?
The term black neck specifically describes a skin condition wherein the area around your neck turns relatively darker than the other parts of your body. This skin condition is also known as dark neck. It is commonly harmless and non-contagious.
In a few cases, the darkening of skin around the neck may be an alarming sign indicating an underlying condition. Hence, it is imperative to consult a doctor to understand the cause followed by appropriate medical action.
Why Is Your Neck Turning Black?
Darkening of the skin around your neck may happen due to various issues including the following:
1. Acanthosis Nigricans
It is a medical condition wherein the affected skin turns dark in colour and becomes thick with a mossy appearance. This condition may affect any part of your body, especially the folds in your skin and neck. It commonly appears in the armpits as well as the groin area. The skin condition may occur in children, women, and men alike. It is highly prevalent in people with a dark complexion.
Acanthosis nigricans  is not harmful or contagious, and is not a disease. The skin condition is often linked with the insulin level of your body. Hence, it is prevalent in people with diabetes or prediabetes. Children and adolescents who experience skin darkening are highly susceptible to type 2 diabetes.
Several other alarming issues which acanthosis nigricans may indicate include:
- Hormonal disorders
- Cushing’s disease
Acanthosis nigricans may also be the result of administering specific supplements and drugs such as prednisone, birth control pills, niacin, and various other corticosteroids.
The treatment plan includes addressing the primary cause of acanthosis nigricans. If this approach doesn’t work, then other treatments involving Vitamin D or retinoid creams are prescribed.
2. Dermatitis Neglecta
It is a medical condition wherein the colour of your skin changes when it hasn’t been properly cleansed. This skin condition usually occurs due to sebum, bacteria, sweat, and other debris build-ups from lack of personal hygiene. This skin condition is also referred to as unwashed dermatosis.
Considered as a rare condition, dermatitis neglecta can be effectively treated and managed by cleansing and washing the affected area with alcohol, water or soap. Furthermore, it can be prevented from reoccurring by maintaining good hygiene practices.
3. Drug-Induced Pigmentation
Your skin may turn dark due to hyperpigmentation, which may occur due to administration of certain drugs  including:
- Antipsychotic drugs
- Nonsteroidal anti-inflammatory medications
The sudden change in skin colour may happen in any part of the body, including your neck. The colour transition varies from blue-black to dark brown tone.
The skin discolouration disappears when the drug responsible for it is not administered anymore. However, in some cases, darkening of skin may be a permanent or long-term incident. In such severe cases, your doctor may suggest you to remove the hyperpigmentation with the help of laser treatment.
Vedix Tip: Before you start with laser treatment, it is advisable to consult a knowledgeable dermatologist or Ayurvedic doctor for safe diagnosis and treatment. Laser treatments are not necessarily safe and helpful for dark skin.

How Is A Black Neck Diagnosed?
A dermatologist or doctor may diagnose the primary cause of your black neck by asking you questions pertaining to your lifestyle choices, medical history, or usage of prescription-based medications.

2. Next, the doctor may perform a few tests to understand the reason behind your skin darkening. These may include:
- Skin sample: A biopsy or skin scraping is recommended to check the presence of fungal cells.
- Blood test: A blood test is recommended to check your hormone or blood sugar levels.
Is Black Neck A Sign Of Diabetes?
People who are obese and overweight often experience dark skin on their neck and under their armpits. They may also observe dark skin on areas of the body with folds and creases such as knuckles, knees, and elbows.
In a few cases, it may be an indication of diabetes or its onset. It is important to consult a doctor as soon as you observe this type of darkening in your skin. This must be followed by a blood sugar test to determine whether you have diabetes.
The skin darkening on the neck and other areas occurs due to overproduction of cells and divergence of fibroblasts from excessive insulin production, especially in obese and type 2 diabetes conditions.
In type 2 diabetes and obesity, the excess fat around the abdominal area in an afflicted individual resists the activity of insulin. This inaction results in overproduction of insulin by the pancreas which regulates the blood sugar levels. The overproduction of insulin leads to unregulated skin cell growth on your neck and other regions along with darkening of skin.
The Last Word
In most cases, the appearance of dark neck isn’t considered as a contagious or harmful skin condition. But sudden skin darkening around your neck may indicate an underlying, serious ailment which might require medical attention and treatment.
Your doctor and dermatologist may help correctly diagnose and treat the primary cause of dark skin, along with discussing treatment plans to help improve your skin complexion and texture.Know Your Dosha Now
