Recent studies suggest that changes in fingernail appearance could be indicative of underlying health conditions, including deficiency symptoms and serious diseases like cancer. Many individuals may overlook the significance of these changes, but a closer examination of one’s fingernails could potentially save lives.
Fingernail Changes Can Indicate Lung Cancer
Various changes in the nails can serve as warning signs of serious diseases. For instance, thickened nails are commonly associated with nail fungus, psoriasis, or neurodermatitis. In some cases, thickened nails accompanied by discoloration may indicate a condition known as “yellow nail syndrome.” This condition is often linked to pneumonia, bronchitis, or lymphedema.
Similarly, individuals with brittle nails that split easily may be experiencing malnutrition, frequent exposure to cleaning agents or nail polish remover, or even overactive thyroid gland or liver disease. It’s important to pay attention to sudden changes in nail texture and seek medical attention.
Another concerning change is the sudden bulging of the nails, which is often seen alongside drumstick fingers – thickened fingertips with protruding nails. These bulging or watch glass nails, as they are commonly referred to, are both lengthwise and crosswise curved, giving them a larger and more rounded appearance. Watch glass nails are often bluish in color.
The Cause of Watch Glass Nails
Experts believe that watch glass nails are a result of chronic tissue oxygen deficiency. This lack of oxygen leads to inadequate blood supply to the fingers, causing the formation of additional capillaries. However, the presence of these capillaries does not resolve the underlying issue of disrupted blood circulation, resulting in the thickening of fingers and abnormal nail growth.
Watch glass nails are commonly associated with lung diseases, such as lung cancer, as they are caused by a persistent lack of oxygen in the body. Other lung conditions like pulmonary fibrosis, pulmonary emphysema, or tuberculosis can also contribute to the development of watch glass nails. In some rare cases, heart diseases that disrupt blood flow, including heart failure, tumors, or inflammation, can also lead to the appearance of watch glass nails.
Furthermore, other medical conditions, including liver diseases like cirrhosis, chronic intestinal diseases such as Crohn’s disease or ulcerative colitis, metabolic diseases like cystic fibrosis, nerve paralysis or damage, and inhalation of toxins like asbestos or chlorine, can all contribute to the deformation of fingernails.
While the appearance of watch glass nails is not directly dangerous, it is essential to consult a doctor immediately if such changes occur. Although lung cancer may be the underlying cause, early detection can significantly increase the chances of successful treatment. Chemotherapy, while impactful on the body, remains a crucial tool in the fight against cancer.
It is always advisable to seek medical attention if any sudden changes in fingernail appearance are observed. Early diagnosis can be vital in detecting and treating various diseases.
