Why do toenails become thick and yellow with hollow inside?

Speaking of nails, everyone knows that healthy nails are transparent with a light pink color, and the transparency is also very good, and they feel smooth like a mirror. Of course, the nails mentioned here include fingernails and toenails. Usually, toenails are hidden in shoes, so some friends will find that their limbs and toes seem to be growing fatter, getting thicker day by day, and the color is yellow, and it seems to be hollow inside. Let's talk about why this is the case.

This is a typical case of "onychomycosis", the most common nail disease. It is mainly caused by lack of attention to hygiene and fungal infection, which leads to thickening and coarsening of nails and the appearance of holes. Pay attention to hygiene.

Onychomycosis is a fungus that grows on the nail plate and secretes proteases to break down keratin, destroying the nail tissue and causing changes in the nail shape, texture, and color. Its metabolites can stimulate tissues such as the nail cuticle, nail bed, and nail folds, causing a series of pathological changes. Once the fungus invades the gap between the nail plate and the nail bed, it will multiply in large numbers inside, significantly affecting the appearance of the nails. This causes the toenails to appear raised, thicken, and have powder deposits inside. It will also cover up the natural pink color of the nail bed, making the nail plate no longer transparent. When the body's resistance is low, it can often invade the tissues under the nail and around the nail, causing damage to the fingers and toes. In severe cases, it can serve as a source of infection and spread throughout the body.

Generally, the treatment is complicated and requires continuous medication for several months. It can be transmitted to others, but most of the time it is self-infected and prone to recurrence. You can take terbinafine hydrochloride tablets orally and use terbinafine hydrochloride ointment externally. Please be careful not to wear other people's slippers. Paying attention to your own hygiene can effectively prevent recurrence. You can also expose your shoes to the sun, which can effectively kill the fungus and help you recover. Remember to check your liver function while taking the medicine, because this medicine can cause serious damage to the liver. If abnormal liver function occurs, it can only be used externally.
