When toenails turn white, it can be a cause for concern. This change in color often signals an underlying issue that should not be ignored. Whether it’s a mild condition or a sign of something more serious, understanding the reasons behind white toenails is essential. This article explores three main causes of toenails turning white: fungal infections, trauma or injury, and underlying health conditions.
Fungal Infections (Onychomycosis)
One of the most common reasons toenails turn white is due to a fungal infection, medically known as onychomycosis. This condition occurs when fungi, such as dermatophytes, invade the nail bed, causing the toenail to become discolored, thick, and brittle.
How Fungal Infections Cause White Toenails
Fungi thrive in warm, moist environments like sweaty shoes or locker rooms. When they get underneath the toenail, they disrupt the healthy growth of the nail, leading to a variety of symptoms:
White spots or streaks: In the early stages, you may notice small white spots or streaks on the surface of the toenail.
Thickened nails: As the infection progresses, the nail becomes thicker, more brittle, and may lift away from the nail bed.
Crumbly texture: The nail can become soft and crumble at the edges, making it prone to breakage.
Certain factors make some people more prone to fungal infections than others:
Walking barefoot in damp places: Gyms, pools, and communal showers are breeding grounds for fungi.
Poor foot hygiene: Not keeping feet clean and dry increases the likelihood of infection.
Tight-fitting shoes: Wearing shoes that trap moisture can create the perfect environment for fungi.
Compromised immune system: People with diabetes or weakened immune systems are at higher risk.
Prevention and Treatment of Fungal Infections
Preventing toenail fungus starts with good foot hygiene. Wash and dry your feet daily, and avoid walking barefoot in public places. Wear breathable shoes and moisture-wicking socks, and consider antifungal sprays or powders if you are prone to sweaty feet.
If you already have a fungal infection, over-the-counter antifungal creams can help in mild cases. However, more persistent infections often require prescription-strength medications such as topical treatments or oral antifungals. In some cases, laser treatments can be used to eradicate the fungus.

Trauma or Injury to the Toenail
Another leading cause of toenails turning white is trauma or injury to the nail. Trauma can happen in a variety of ways—stubbing your toe, dropping something heavy on it, or wearing shoes that are too tight can all lead to white discoloration.
How Trauma Leads to White Toenails
When a toenail is injured, the damage to the nail bed can disrupt blood flow to the area. As a result, the toenail may become discolored, turning white or even black depending on the severity of the injury.
Common signs of nail trauma include:
White spots or lines: Minor trauma often leads to the appearance of small white spots or horizontal lines, known as leukonychia.
Nail detachment: Severe trauma can cause the nail to partially or fully detach from the nail bed, which often results in a white appearance as the nail lifts away.
Common Causes of Nail Trauma
Ill-fitting shoes: Shoes that are too tight can press on the toenails, leading to micro-trauma over time.
Sports injuries: Athletes, particularly runners and soccer players, frequently experience nail trauma due to repeated impact on the toes.
Accidents: Dropping heavy objects or bumping toes against hard surfaces can result in bruising and nail discoloration.
Treatment for Traumatized Toenails
If your toenail is white due to trauma, the best course of action is to give it time to heal. In mild cases, the nail will grow out normally. However, if the nail becomes painful, starts to lift from the nail bed, or shows signs of infection (such as redness, swelling, or pus), you should seek medical attention.
The Houston podiatrist at DeNiel Foot and Ankle Center can assess the injury and determine if additional treatment is necessary. They may recommend trimming the nail, draining any fluid buildup, or, in severe cases, removing the nail entirely to allow a new one to grow in.
Underlying Health Conditions
While fungal infections and trauma are common causes of white toenails, they can also be a sign of more serious underlying health conditions. In these cases, the change in color is often accompanied by other symptoms that should not be overlooked.
Health Issues Associated with White Toenails
Psoriasis: This autoimmune condition affects the skin and nails, leading to pitting, thickening, and white discoloration of the toenails.
Liver or kidney disease: In some cases, white toenails can indicate problems with the liver or kidneys. When these organs are not functioning properly, they can cause a buildup of toxins that affect nail health.
Circulatory issues: Poor circulation, especially in the feet, can cause nails to turn white. This is common in individuals with conditions like diabetes or peripheral artery disease (PAD).
Anemia: A lack of healthy red blood cells can result in white, brittle nails.
Seeking Medical Advice
If you suspect that your white toenails are related to an underlying health condition, it’s crucial to consult with a healthcare professional. In these cases, treating the root cause of the problem, such as managing psoriasis or improving circulation, can help resolve the nail discoloration.

When to See a Podiatrist
While white toenails are not always a cause for alarm, they shouldn’t be ignored, especially if they are accompanied by pain, swelling, or changes in nail shape. If your toenails remain discolored despite good hygiene, or if the condition worsens, it’s time to consult a podiatrist.
A podiatrist can determine whether the problem is due to a fungal infection, trauma, or a more serious underlying condition. With early intervention, treatment is often straightforward, and complications can be avoided.
