Acanthosis nigricans is a common skin problem often seen in the association of obesity. Now-a-days it has been very common among young children and adults. It deserves some special attention as it may be a future marker of diabetes. Good news is that you can prevent that from happening with some simple tips that we share in this article.
The skin manifestation of acanthosis nigricans is darkening of the neck along with some degree of skin thickening. Other than neck it is often seen in the armpit and groin as well. Children can also be affected. AN (Acanthosis nigricans) should be suspected whenever you find black thickening of the neck or armpit in an overweight person.
Of Course all black necks are not due to AN. Many other diseases including common ones like Atopic dermatitis (a type of allergy in children) or some type of fungal infection can produce similar pictures. However physicians can usually tell whether it is AN just by looking at it. So when in doubt, it is the best idea to visit a doctor.
To understand the relationship of AN with diabetes, you need to know a very basic knowledge of how AN develops.
The thickening and blackening of skin is actually due to some abnormal growth of certain types of cells in your skin in response to some chemicals that come via your blood and then stimulates the growth of those cells. Insulin (the hormone which becomes deficient in diabetes) is one of such chemicals.
Now, when someone gains weight, an interesting thing happens. You probably know that insulin is an essential hormone that needs to act on every cell of your body to insert glucose inside the cell (the glucose will help in energy production , which will keep the cell alive). But they are less effective on fat cells. So when the number of fat cells in your body increases, insulin would find it difficult to do its work effectively. In response, your body would then increase insulin production to handle the job. It will thus produce the abnormal skin darkening and thickening as explained in the last paragraph.
So, when does Diabetes come into the picture ? Actually if the process continues, and the body keeps producing high levels of insulin for a long time, eventually it will end up destroying its own insulin producing cells and then diabetes (Type II) will develop.
So technically AN (acanthosis nigricans) can be regarded as an indirect sign that diabetes might develop soon (or has already developed). How can we be certain of that ? If diabetes has already developed, then there will be an increased level of glucose in your blood (as not enough insulin is there to push them inside the cells), or if it is yet to develop then there will be an increased level of insulin in your blood (as explained before). If the latter is the case, it indicates pre-diabetes and there is still a chance that you can prevent diabetes from happening if you can reverse the process. So physicians often perform those tests (Fasting blood glucose level and Fasting insulin level - fasting because food will hamper the level ) to be certain.
In this era of junk-foods, health-drinks and social media , it is very common that teenagers are gaining abnormal weight. They are mostly at the stage of pre-diabetes (increased blood level of insulin) and it is possible through a healthy lifestyle and weight reduction, that they can reverse the stage and prevent a deadly disease like diabetes from happening.
Theoretically, there are many conditions (as described in medical textbooks) that might be the cause of AN apart from obesity but they are usually very rare (means that you should let your doctor worry about it (if needed) and stop doing research yourself ! )
If you still want to intuitively understand what might be the other causes, recall the mechanism behind AN from the last section, it happens when certain cells of your skin get over-stimulated due to certain chemicals like insulin.
So it is important that when you visit a doctor you answer all his/her questions correctly including any other disorder / symptoms you have or any other medicine you are taking.
It is always a good idea to maintain a healthy weight through diet and exercise (even when you do not have acanthosis nigricans). (Check if you have healthy weight)
So if you are overweight, the best course of action is to lose some weight gradually.
You can lose weight when the calorie you lose will be more than the calorie you gain.
To lower the calorie gain, you need to limit your food intake. Specially those with high calorie such as carbohydrates like rice or bread as well as junk foods.
Actually the food type has a deeper association with AN or diabetes which is beyond the scope of this article. For the sake of simplicity, just remember the rule of thumbs : the more some food is processed (Away from its natural state, though it usually makes it more tasty) , the more harmful it is. For example brown rice is less harmful than fine white rice. That’s why pizza and burgers are harmful as they are made of refined and processed flour. Sugar is processed from sugar cane plants so food that contains high amounts of free sugar (such as cold-drinks) are much more harmful than fruit juices or coconut water (as they are naturally derived).
You can take help from our diet chart maker to make an appropriate diet chart for you or if that seems too complex, taking help from a dietitian would be better.
The other way to tilt the calorie equation is ofcourse to increase the calorie you lose. The way people lose their calorie is usually by two ways.
Along with the advice of weight loss, your doctor might give you some specific treatments for the conditions. However, please remember that weight reduction is still the best mode of treatment.
Here are some possible medicines your doctor might advise.
