Causes of discoloration of toenails and thickening beyond fungi

Many people assume that all nails that are discolored, thick, or of another abnormal appearance are infected by fungus fingernails. While this is true in many cases, there are many other conditions that can cause discoloration and surface changes to the toenails. These conditions are not treatable by the popular drugs used to fight the fungus nail, which leads many to believe that the drugs are not as effective as the claims of the research against what was supposed to be a fungal infection. This article will cover some of the most common conditions that can cause nail changes, so that the difference between fungi and a completely different nail condition can be appreciated.

The most common reason why a fingernail becomes discolored, thickened, irregularly shaped, or otherwise unnatural has nothing to do with illness or infection. Most of the time, nail changes are simply due to the basic mechanical pressure. The tissue that pushes the nail towards the outside (the nail matrix) is quite fragile, and even a slight pressure over time can cause the abnormal growth of this tissue. This tissue rests on the bone under the base of the nail behind what is commonly called the cuticle. Toes treat pressure at the top of the toe and at the end of the toe all day long. The pressure can take the form of a single fast event, such as a heavy weight falling on the toe, or gradually, as when someone with a second toe long frequently wears tight shoes. The lesions directly damage the nail matrix, or cause the nail lift of the skin underneath due to bleeding pressure which in turn harms the nail matrix or the skin under the nail itself. The pressure exerted by the shoes due to improper adjustment or toes positioned too high up the shoe (due to birth position or slowly developing deformities such as hammertoes) may result thickened and discolored nails. This is due to an accumulation of the nail itself, or to the hard tissue underneath. This process is irreversible because the nail matrix is ​​usually permanently damaged, although nail softeners may help dissolve some of the keratin (nail and skin matter) that Accumulates in this area. It's not uncommon either that nails get thicker as we get older. This may be due to a combination of all the factors discussed above, or simply because of the decreased circulation or quality of the skin tissue in general.

Another common reason why fingernails become discolored or irregularly shaped is due to diseases elsewhere in the body. There are many conditions that will cause discoloration of the nails. Conditions such as heart and kidney disease can cause changes in red and brown in the nails, respectively. Liver diseases and malnutrition can cause the formation of fine white lines on the nail from one side to the other, as well as various types of chemical poisoning, such as the 39, arsenic and carbon monoxide. Completely white nails can also indicate liver disease, thyroid disease, malnutrition and diabetes. The blue-gray nails are most often due to a simple bleeding under the nail of an injury, but can also indicate a poisoning to the money. Red streaks similar to splinters may be the result of heart infection, cancers elsewhere in the body, pregnancy, as well as various autoimmune-like arthritic and connective diseases such as rheumatoid arthritis and lupus. Chemotherapy can also discolour fingernails to varying degrees, and even make them fragile and loose.

Various skin conditions can also change the appearance of the nail. For example, psoriasis can cause nail bites and a stain of oil like a stain under the nail. The bites can also be caused by a wide variety of allergic and autoimmune / rheumatological conditions.

The most important nail change that is mistaken for a fungus or bruise appears as a dark streak in the nail. This streak starts at the base of the nail and can come out of the end of the nail. Unlike nail bruising, this discoloration is somewhat contained in the length direction, more like a trail and less like a stain. In dark-skinned people, this is a common finding and is usually benign. In fair-skinned individuals, especially those with pigment changes on the skin surrounding the nail line, this could indicate melanoma. This is a diagnosis that needs to be done quickly and accurately because melanoma can be deadly. The rapid assessment by a doctor of any new dark streaks in the nail and the surrounding skin must be made, assuming it is a fungus or bruise can be a deadly mistake. The symptoms of higher risk factors for nail melanoma include a new streak in a light-skinned individual, a sudden change (widening, darker, etc.) in an existing streak, the occurrence of A single nail, skin pigmentation around the nail, new streak in a senior (60-79 years old), a streak width of more than 3 millimeters, as well as a family history of melanoma .

As can be seen, many conditions can cause changes in nails. In all fairness, should not assume that every little change to their fingernail could indicate an important illness. These types of nail changes are not common, but the underlying point is that not everything is related to the fungus by considering the causes of abnormal nails.
