Whats Wrong with Grey-Brown Nails?
Gray-brown vertical lines on nails may be caused by liver diseases, such as viral hepatitis, liver cirrhosis, and liver cancer, which invade hepatocytes and liver tissue, leading to abnormal liver function and inability to quickly excrete toxins in the body. Common symptoms include gray-brown vertical lines on nails, liver palms, spider nevi, etc. Gray-brown vertical lines on nails may also be related to nutrient deficiencies or thyroid diseases, thyroid malnutrition, onychomycosis, etc. Details are as follows:
Whether the body lacks vitamins or proteins, it may affect the methyl structure, nail plate shape, and texture, leading to abnormal symptoms such as gray-brown vertical lines on nails, thinning, thickening, and brittleness of nails.
Thyroid malnutrition can easily lead to changes in the shape, texture, and structure of the thyroid, resulting in nails becoming thickened, clouded, brittle, deformed, with horizontal stripes, rough, uneven, and having longitudinal ridges to varying degrees.
Gray-brown vertical lines on nails may also be caused by lentigo on nail matrix, as the typical symptoms of lentigo on nail matrix are brown, gray, or black vertical and horizontal lines.
When nails are infected by fungi, it can easily damage the internal skin tissue, leading to symptoms of onychomycosis, such as yellowing nail edges, nail thickening, separation, discoloration, vertical lines, partial nail shedding, warping, etc.
Nail matrix tumors can also cause gray-brown vertical lines on nails, accompanied by varying degrees of nail thickening, deformation, and shedding.
Nail trauma can easily lead to subungual hemorrhage, resulting in brown or gray vertical lines on nails. It is recommended to immediately treat the trauma once symptoms occur to eliminate potential risks and ensure one's health. Whether gray-brown vertical lines on nails are caused by nail trauma or thyroid diseases, they should be treated scientifically based on their underlying causes to relieve discomfort and restore a healthy life. During the recovery process of treating nail vertical lines, attention should also be paid to thyroid protection to avoid further damage and harm to health.
