What causes black spots under toenails. How to identify different types of toenail discoloration. When should you be concerned about a dark spot under your toenail. What treatments are available for various causes of toenail discoloration.

Common Causes of Black Spots Under Toenails

Black spots under toenails can be alarming, but they’re often harmless. However, in some cases, they may indicate a more serious condition. Understanding the potential causes can help you determine whether medical attention is necessary.

Subungual Hematoma: Blood Beneath the Nail

A subungual hematoma, or blood beneath the nail, is a common cause of black spots under toenails. This condition often results from trauma to the toe, such as:

• Impact injuries (e.g., dropping a heavy object on your foot)
• Stubbing your toe
• Wearing tight shoes that compress your toes
• Keeping your toenails too long, causing them to press against your shoes

In most cases, subungual hematomas are harmless and comparable to bruising beneath the skin. However, depending on the extent of the bleeding, you may lose your toenail. If this occurs, don’t panic – the nail will usually grow back within 9-18 months.

Fungal Nail Infections

While toenail fungus typically causes yellow discoloration, it can also lead to green, brown, or black spots. You can distinguish fungal infections from other causes by looking for additional symptoms such as:

• Brittle or crumbly nails
• Thickened nails
• Distorted nail shape

Fungal nail infections require treatment to prevent spreading to other toes or household members. Anti-fungal laser treatment is highly effective compared to traditional methods like creams, lacquers, powders, and tablets.

Bacterial Infections and Their Impact on Toenail Appearance

Bacterial infections, particularly pseudomonas infections, can cause green-black discoloration of the toenail. Unlike fungal infections, bacterial infections require immediate treatment due to the risk of the infection entering the bloodstream.

Symptoms of Bacterial Toenail Infections

• Rapid onset of green-black discoloration
• Pungent, sometimes sweet-smelling odor from the feet
• Often associated with moist environments (e.g., swimming, hiking)

Individuals with conditions like psoriasis may be more susceptible to bacterial nail infections due to pre-existing nail damage. If you suspect a bacterial infection, seek medical attention promptly.

Medical Conditions Associated with Toenail Discoloration

In some cases, black spots under toenails can be a side effect of underlying medical conditions, including:

• Diabetes
• Kidney problems
• Heart disease
• Anemia

If you have any of these conditions and notice toenail discoloration, inform your healthcare provider. The appearance of your nails can sometimes serve as an indicator of how well your treatments are working.

Melanoma: When to Be Concerned About Skin Cancer

While rare, black spots under toenails can sometimes indicate melanoma, a dangerous form of skin cancer. It’s crucial to be aware of the signs and seek medical attention if you’re concerned.

Identifying Potential Melanoma Under the Toenail

• May appear as a round black mole or a streak in the nail
• Often painless and without other symptoms
• Can cause changes in nail shape and surrounding skin over time

If you suspect melanoma, avoid painting your nails so you can monitor for changes in shape, size, or pigmentation. Consult a healthcare professional immediately for proper evaluation and potential biopsy.

Nail Polish and False Alarms

Sometimes, what appears to be a black spot under your toenail may simply be residual nail polish. Before panicking, try removing any nail polish and thoroughly cleaning your nails to rule out this harmless cause.

Diagnosis and Treatment Options for Toenail Discoloration

Proper diagnosis is crucial for effective treatment of black spots under toenails. A healthcare professional, such as a podiatrist or dermatologist, can perform a thorough examination and recommend appropriate tests or treatments.

Diagnostic Methods

• Visual inspection
• Nail clippings for fungal culture
• Dermoscopy for detailed examination
• Biopsy in cases of suspected melanoma

Treatment Options

Treatment depends on the underlying cause of the black spot:

1. Subungual hematoma: Often resolves on its own, but may require draining in severe cases
2. Fungal infections: Antifungal medications or laser treatment
3. Bacterial infections: Oral or topical antibiotics
4. Melanoma: Surgical removal and potential additional cancer treatments

Prevention and Nail Care Tips

While not all causes of black spots under toenails are preventable, you can take steps to maintain healthy nails and reduce your risk of certain conditions.

Preventive Measures

• Keep nails trimmed and clean
• Wear properly fitting shoes
• Use protective footwear in public areas like pools and locker rooms
• Avoid sharing nail care tools
• Moisturize your feet and nails regularly

By following these tips and being aware of changes in your toenails, you can promote better nail health and catch potential issues early.

When to Seek Medical Attention for Toenail Discoloration

While many causes of black spots under toenails are benign, certain situations warrant immediate medical attention.

Red Flags for Toenail Discoloration

• Rapid onset or spread of discoloration
• Accompanying pain or discomfort
• Changes in nail shape or texture
• Persistent discoloration that doesn’t improve
• Personal or family history of skin cancer

If you experience any of these symptoms or have concerns about a black spot under your toenail, consult a healthcare professional promptly. Early detection and treatment can significantly improve outcomes, especially in cases of potential melanoma.

Understanding the Impact of Lifestyle on Toenail Health

Your lifestyle choices can significantly influence the health of your toenails and contribute to or prevent the development of black spots. Consider how various factors may affect your nail health:

Physical Activity and Toenail Trauma

Certain sports and activities can increase the risk of toenail trauma, potentially leading to subungual hematomas. These include:

• Running and jogging
• Soccer and football
• Dancing, particularly ballet
• Hiking and mountaineering

While it’s important to stay active, be mindful of proper footwear and techniques to minimize the risk of toenail injuries.

Nutrition and Nail Health

A balanced diet rich in essential nutrients can promote healthy nail growth and reduce the risk of discoloration. Key nutrients for nail health include:

• Biotin (Vitamin B7)
• Iron
• Zinc
• Protein
• Omega-3 fatty acids

Ensuring adequate intake of these nutrients through diet or supplements can contribute to stronger, healthier nails less prone to discoloration and damage.

Footwear Choices and Their Impact

The shoes you wear can significantly affect your toenail health. Consider the following when selecting footwear:

• Proper fit with adequate toe room
• Breathable materials to reduce moisture
• Supportive soles for even weight distribution
• Protective features for specific activities (e.g., steel-toed boots for construction work)

By choosing appropriate footwear, you can reduce the risk of toenail trauma and fungal infections that may lead to discoloration.

The Role of Regular Foot Examinations in Preventing Serious Conditions

Regular self-examinations of your feet and toenails can play a crucial role in early detection of potential issues. By incorporating foot checks into your routine, you can catch and address problems before they become more serious.

How to Perform a Thorough Foot and Toenail Examination

1. Clean and dry your feet thoroughly
2. Examine each toenail for discoloration, changes in shape, or texture
3. Check the skin around your nails for signs of infection or irritation
4. Look between your toes for any unusual spots or growths
5. Feel for any lumps, bumps, or tender areas on your feet
6. Note any changes in sensation, such as numbness or tingling

Perform these examinations at least once a month, or more frequently if you have risk factors such as diabetes or a history of foot problems.

Documenting Changes in Toenail Appearance

Keeping a record of any changes in your toenails can be invaluable for monitoring potential issues and discussing them with healthcare providers. Consider the following methods:

• Take regular photos of your toenails for comparison
• Keep a journal noting any changes in color, texture, or shape
• Record any associated symptoms, such as pain or discomfort
• Note the date of onset for any new spots or discolorations

This documentation can help healthcare professionals track the progression of any conditions and make more informed decisions about treatment.

Addressing Psychological Impact of Toenail Discoloration

While the physical aspects of black spots under toenails are important, it’s also crucial to consider the potential psychological impact. Visible nail discoloration can affect self-esteem and social interactions, particularly during activities where feet are exposed.

Coping Strategies for Toenail Discoloration

• Educate yourself about the cause of your toenail discoloration
• Focus on treatment and prevention rather than concealment
• Practice self-care and stress-reduction techniques
• Seek support from friends, family, or support groups
• Consider professional counseling if the issue significantly impacts your quality of life

Remember that many causes of toenail discoloration are treatable, and with proper care and patience, your nails can often return to their healthy appearance.

Advances in Toenail Diagnostics and Treatment

The field of podiatry and dermatology continues to advance, offering new and improved methods for diagnosing and treating toenail discoloration. Stay informed about these developments to ensure you’re receiving the most up-to-date care:

Emerging Diagnostic Tools

• Advanced imaging techniques for early melanoma detection
• Genetic testing for predisposition to certain nail conditions
• Artificial intelligence-assisted analysis of nail appearance

Innovative Treatment Options

• Photodynamic therapy for fungal infections
• Nanotechnology-based topical treatments
• Personalized medicine approaches based on genetic profiles

While these advances are promising, it’s important to consult with healthcare professionals to determine the most appropriate diagnostic and treatment options for your specific situation.

By staying informed about the causes, prevention, and treatment of black spots under toenails, you can take proactive steps to maintain healthy feet and nails. Remember that early detection and proper care are key to addressing any potential issues effectively. If you have concerns about your toenail health, don’t hesitate to seek professional medical advice.

What’s Causing The Black Spot Beneath My Nail? – My FootDr

As having black spots beneath our toenails is far from the norm for most people, it’s not surprising that they can ring alarm bells and cause concern. Especially when we think back to favourites like Bob Marley who passed away at age 36 from a melanoma (which appears like a dark patch under the nail) that started beneath his toenail.

The truth is that there are a variety of causes for dark spots beneath the nails. Most of these aren’t pretty to look at, some of these can be associated with discomfort or ongoing problems, some are harmless, and in the least common but most extreme cases, some may be a sign of cancer.

To help, your My FootDr podiatry team have shared the top six causes of black spots beneath the toenails.

1. Blood Beneath The Nail 

This is what we call a subungual haematoma which translates to blood beneath the nail. There are many reasons why you may get bleeding beneath the nail, and before you worry, most of these are harmless and comparable to getting bruising beneath your skin.

Examples include impact injury, like having your toe stood on in sports or dropping something heavy on your foot, stubbing your toe, wearing tight shoes that press on your toes, keeping your nails too long so that they’re constantly buttressing against the end of the shoe, and the like.

Depending on the size of the bleeding and the spot, you may lose your toenail. If this happens, it’s likely that the nail will simply grow back with little harm done, though as toenails grow slowly, it may take anywhere from 9-18 months.

2. Toenail Fungus

While we traditionally know and recognise fungal nail infections as having a yellow discolouration, it may also be green, brown and black, too. You may distinguish toenail fungus from other causes of black discolouration by looking for other common features like brittle, crumbly or thickened nails. 

Again, fungal nail infections are not a cause for alarm bells, but they do require treatment to stop the infection from spreading to your other toes, and to others within your household. We highly recommend using anti-fungal laser to treat fungal nail infections as it has superior effectiveness over traditional methods like creams, lacquers, powders and tablets.

3. Bacterial Infection

Specifically speaking, we’re talking about a pseudomonas bacterial infection. Unlike nail fungus which often doesn’t pose any immediate dangers to our health, bacterial infections require immediate treatment because of the way they affect our bodies and put us at risk of the infection entering our bloodstream – which is when things can get very serious, very quickly. 

If you have this bacterial infection, it can pop up quite quickly to produce green-black discolouration on the nail. You’ll likely have a pungent smell coming from the feet, which may almost smell sweet. As this bacteria has a preference for moist environments, particularly the muddy outdoors, you may be a regular swimmer or have recently completed a hike or tramp.

You may also have a condition like psoriasis that originally caused damage to the nail, allowing the bacteria to penetrate and take hold more easily. Regardless of how it came to be, it’s important that you have this infection treated immediately.

4. Medical Conditions

Sometimes, black discolouration is a side-effect of other conditions like diabetes, kidney problems, heart disease and anaemia, to name a few. If that’s the case, managing the discolouration relies heavily on managing the original problem effectively. 

If your GP or specialist doesn’t already know about the discolouration linked to your other medical conditions, make sure you tell them at your next appointment so they can keep any eye on the progression – it can often be a handy indication on how your treatments are going.

5. Melanoma (Skin Cancer)

We had to get to this one eventually, right? There’s always a chance that the black spot beneath your nail is actually a mole, and that the mole may be a malignant melanoma, which is a dangerous and severe form of skin cancer. It may appear as a round black mole, or it may appear as a streak in the nail – which is what it did for Bob Marley. 

Melanomas aren’t typically painful or symptomatic, so it’s really important to let everyone know about it – your podiatrist, your GP, your skin specialist – and keep a close eye on it yourself. If you’re worried about a melanoma, definitely avoid painting the nail so you can monitor for any changes, like in shape and pigmentation, and signs that it’s getting bigger.

Over time, it may cause discolouration and changes in the areas surrounding it too. Melanomas are not something you want to take a chance with or ignore and hope for the best. You must have it seen to immediately.

6. It’s Your Nail Polish

Ending with our least concerning cause – for many people, wearing dark nail polishes over time can discolour their nails. Usually, it only affects the top layer of the nail and doesn’t affect the area beneath the nail at all. Which is great news as in most cases, we’re able to use a nail burr to immediately remove that top discoloured layer and fix the problem! Just book in for one of our nail care appointments.

Concerned About What You’re Seeing?

Nail problems should never have you worried or keep you awake at night – and if they are, we highly recommend trusting those instincts and having your nails checked. Our podiatry team will give you an idea of what the likely cause for your nail discolouration is and treat it accordingly – or refer you to a specialist if we suspect something more sinister or further investigation is required.

A narrow black line that has formed vertically underneath your nail is called a splinter hemorrhage. It may be harmless or a sign of a more serious health condition.

This condition is called a splinter hemorrhage because it may look like a wood splinter under your nail. The condition is caused by damaged small blood vessels underneath your nail. Characteristics include the following:

• It’s black or reddish brown in color.
• It doesn’t change appearance when you apply pressure to the nail.
• It appears on one or more places under your nail.

Thicker lines that create a horizontal stripe on the nail are called Beau’s lines. These are usually not harmful, but they may be a symptom of a cancer called subungual melanoma.

Black lines on the nail can be the result of many conditions.

Trauma is one of the most common causes of splinter hemorrhages. This can occur when something hurts your nail bed and bursts a blood vessel under your nail. You may also experience nail trauma without even realizing it, such as when you squeeze something very tightly.

Endocarditis is a heart condition that may cause splinter hemorrhages. Fifteen percent of those with endocarditis have splinter hemorrhages. Endocarditis occurs when the inner chambers or valves of the heart have an infection. You may experience other serious heart conditions as a result of endocarditis. Endocarditis generally occurs in those with preexisting cardiac conditions.

Psoriasis may also cause splinter hemorrhages. Psoriasis is a chronic skin condition that can manifest as silvery plaques, or scales on the skin. Up to 50 percent of those with psoriasis experience splinter hemorrhages and other nail conditions.

Causes of splinter hemorrhages vary and may include:

• infections
• vasculitis
• lupus
• nail fungus
• lichen planus
• medications that alter blood clotting
• Raynaud’s disease
• kidney, lung, or circulatory diseases
• chemotherapy

Beau’s lines on all 20 nails may be a sign of:

• mumps
• thyroid disease
• diabetes
• syphilis

Contact your doctor if you’re sure a black line on your nail wasn’t caused by trauma. If the trauma has caused another condition or doesn’t seem to be healing on its own after several weeks, you should see your doctor.

If you don’t already have a doctor, the Healthline FindCare tool can help you find a physician in your area.

If you suspect the splinter hemorrhage is the cause of a more serious health condition, you should contact your doctor for an appointment. For example, if you have endocarditis, you may experience symptoms like fatigue, a fever, pale skin, joint pain, and shortness of breath, among others. Psoriasis may appear as a rash, patches, or scales on your skin, particularly on your scalp, face, hands, feet, and skin folds.

Splinter hemorrhages that recur or are on more than one nail should also be reviewed by a doctor.

When you see your doctor, expect them to take a medical history and perform a physical exam. Your doctor may recommend further testing after your appointment if an underlying condition is suspected.

Treatment of the splinter hemorrhage will vary based on the underlying cause of the condition. In some cases, you may not need any treatment, and the splinter hemorrhage will grow out with the nail.

If the splinter hemorrhage is a sign of another medical condition, you should see your doctor for treatment. The health conditions causing splinter hemorrhages are quite different, so there is no standard treatment to improve the nail condition. For example, endocarditis requires antibiotics and possibly surgery. Psoriasis is a lifelong condition that requires various topical and oral treatments as well as prevention strategies.

Splinter hemorrhages may be harmless, or they may be a sign of a more serious health condition. If you can recall a trauma to the nail, it’s likely the splinter hemorrhage will grow out with time. If you experience symptoms in addition to the nail condition, you should see your doctor for a thorough examination and diagnosis.

Nails can be an indicator of your overall health. If you experience splinter hemorrhages or other nail conditions without a reasonable explanation, it may be a sign that you should see your doctor.

Black spot under the nail – causes, treatment and prevention

June 11, 2021

The appearance of black spots or stripes under the nails is a serious cause for concern. Many are concerned about the question of whether it is possible to fix the problem on their own. It all depends on the nature of the damage and the causes that caused it.

The black spot under the nail can be of different size, localization and origin. There are many reasons for its appearance – they are both external and internal. Let’s consider the main ones.

Mechanical damage

Black spot under the nail in most cases is the result of subungual hemorrhage. It is formed due to mechanical damage – impact or pinching. The physics of this phenomenon is simple: the vessels that are under the nail plate are torn, and the blood is in the intercellular space.

The color of the stain may vary depending on the severity of the injury. The shape also varies – from stripes to round spots with clearly defined edges.

The problem often occurs in people involved in sports and leading an active lifestyle. In this case, the main location of the spot is the big toes. It is on them that the greatest physical impact is exerted. Wearing tight shoes or shoes with a narrow toe can also be the cause of the problem. Even a couple of hours in uncomfortable shoes negatively affect the nail bed, cause microtrauma and rupture of blood vessels.

How to deal with damage to the nail plate

If the degree of damage to the nail is minor, over time the damage will resolve without outside help. The nail will grow, and the stain will move along with it. After a while, it will be possible to simply cut off the darkened section of the plate.

Tactics of treatment for traumatic damage to the nail plate is as follows:

Applying cold. This will help stop internal bleeding and localize damage.

Elevated position of the arm or leg. It is necessary to take a prone position and raise the limb so that it is above the level of the heart. This will help stop bleeding and prevent swelling.

Care for the injured limb within 7-14 days. During this time, all healing processes will be completed.

If the injury is extensive and the black spot occupies most of the nail, you will not be able to avoid going to the doctor. The specialist will puncture the nail to remove the accumulated blood. If this is not done, serious complications may occur.

Malfunctions of the internal organs

Dark spots can be one of the symptoms of malfunctioning of the internal organs. The main pathologies that provoke such changes in the nails are:

• endocarditis;
• diabetes mellitus;
• anemia;
• systemic lupus erythematosus;
• kidney pathology.

In addition to dark spots under the nails, there are always other unpleasant symptoms. You can get rid of an aesthetic defect on the nail plate only by eliminating the root of the problem.

In addition, darkening of the nail can be caused by alcoholism, the systematic use of drugs, and the use of a number of medications. Often, dark spots occur as a result of chemotherapy.

Ingestion of pathogenic microorganisms

The appearance of black spots on the nails may be a symptom of infection with a fungus or Pseudomonas aeruginosa.

Fungal infection completely changes the structure and appearance of the nail. In addition to dark spots, there is deformation, thickening of the plate, ribbing, unpleasant odor, pain, itching. This problem is most often localized on the toes. It will not be possible to solve it on your own – you need to contact a specialist who will select antifungal drugs.

Bacterial infections are a serious condition requiring immediate medical attention. They are fraught with complications, up to blood poisoning and death. The main symptom of a bacterial infection is the black-green color of the nail. The problem in most cases is localized on the fingers. Often, a change in the plate is detected under the coating during the removal or correction of gel polish.

The above situations are a common result of an incorrectly performed manicure. That is why it is important to use only proven professional equipment. Many experienced craftsmen recommend using MAX manicure vacuum cleaners, arm rollers, as well as other company accessories. Its products are designed to meet all the requirements of nail-specialists and customers.

Psoriasis

Black spots under the nails are one of the possible symptoms of psoriasis. Autoimmune pathology affects many organs and systems, affects blood circulation. In this case, the spots look like small stripes, localized both on the legs and on the arms. Occur due to microrupture of capillaries.

Squamous cell carcinoma

Melanoma can be a symptom of dark spots under the nails. Its main causes are genetic predisposition, advanced age, constant exposure to UV rays on the nail plate.

The main sign of melanoma is a blurry spot of a non-uniform color. It does not have well-defined edges. In the process of nail regrowth, the scale of the problem only increases, spreading to the entire plate. Most often localized on the big toes and hands.

If you suspect squamous cell skin cancer, see a dermatologist immediately. The disease is successfully treated if it is detected in the early stages.

Whom to contact if there is a dark spot under the nail

Changing the nail plate is an unpleasant aesthetic problem. Spots can be completely harmless or indicate serious pathological processes in the body. If dark spots under the nails are not the only disturbing symptom, you should consult a doctor. He will conduct a comprehensive examination and select the correct treatment tactics. If you have not injured the nail, but the stain is present, immediately make an appointment with a podiatrist or dermatologist!

The key to successful treatment of any pathology is timely diagnosis. The sooner you see a doctor, the more likely it is to fix the problem without surgery. If you delay going to a specialist, this is fraught with serious consequences, up to the complete removal of the nail plate and subsequent long-term corrective treatment.

If you are diagnosed with a fungal infection of the nail plate, the doctor will start complex therapy. It involves the removal of the affected layer of the nail with the help of a special apparatus. You will also need to take a course of antifungal therapy. It can include both medicines in the form of tablets and special ointments.

In no case should you ignore changes in the nail and dark spots that are not associated with mechanical damage. If you are sure that you have not injured your finger, immediately make an appointment with a dermatologist or podiatrist.

1. Strokes, hematomas. Ordinary hematomas or bruises under the nails are the accumulation of blood in the tissues under the nail plate as a result of a blow or bruise. Since in itself it is quite rigid, and the soft tissue is firmly connected with the plate, the destruction of the capillaries is accompanied by an accumulation of blood that cannot come out from under the nail. So dark, brown-red, brown spots appear under the nail plates. Sometimes a person simply cannot remember after what injury they appeared. Especially when it comes to toenails.
2. Increased body pigmentation. This refers to sensitivity to the action of bright sun, water, harmful chemicals that lead to stains on the nails. Such sensitivity can even change the color of the eyes. That is, if moles regularly appear on the human body, then this indicates the predisposition of the body to the effects of the environment, the result of which is pigmentation. The same can be said about nails. This means that the frequent appearance of spots of this kind on the nails without a visible deterioration in well-being should not scare you. This is how seasonal changes in the level of pigmentation appear.
3. The presence of cancer cells in the body. With a sudden, one-time appearance of black dots on the nail plates, as well as moles and birthmarks, there is cause for alarm. This may mean that blood metastases – cancer cells – are increasing. That is why when black dots appear under the nails, you should definitely undergo a medical examination.
4. Liver problems. Black spots may be associated with incipient liver problems. Its function in the body is a barrier, it filters out substances that are not needed and harmful to the body. If the liver does not properly cope with such duties, then harmful substances pass through it and enter the bloodstream. They can also spread under the nails. In this case, it is necessary to treat the liver, and this is a separate problem and topic.
5. Nail fungus. Black dots, dark spots on the nail plates of the hands and feet may be the result of infection with this type of fungus. The color of the nail in this case can be yellow, green, brown. As a rule, mold fungi are infected by people whose immunity was too weakened during some kind of illness. That is, the fungus in this case receives fertile ground for introduction into the body and reproduction in it. And just black dots can be signs of the second stage of infection with this type of fungus. With it, the defeat of the nail plate modifies it and the nail bed. It suffers first. Next, the nail folds are changed. Bloating, redness, filling them with pus are clear signs of moldy nail fungus. When the nail fold breaks through, it can lead to infection if it is not isolated and decontaminated. Then the nail plate also undergoes changes, starting to warp, bend, soften in waves. In this serious case, treatment should be started as soon as possible. The sooner this happens, the sooner your nails will return to normal and the black dots under them will disappear.

Blackening of the nail occurs as a result of internal or external factors affecting the body. Most often, the nail on the big toe turns black due to hemorrhage, the cause of which is mechanical damage, trauma. A bruise is an optional cause of injury, wearing tight shoes is also a common cause of burst blood vessels. If the nails on the big toes have darkened due to an injury, you should not worry about the state of health, but remember that the natural color of the plate may not return. Darkening disappears only after the growth of a healthy plate.

Injury is fairly easy to spot. Spots on the toenails in case of injury have a local location. With blurry edges, you can see a clear outline of the spots. Over time, the spot blackens more, acquiring sharp boundaries. Severe trauma is accompanied by detachment of the nail plate from the bed.

Occasionally the nails turn black due to external staining. A dark spot may form upon contact with potassium permanganate. Such a darkening of the body does not harm, but it is problematic to remove it.

The use of low-quality nail polish without applying a protective base may be associated with the formation of dark spots on the nails. The reason for the darkening is aggressive chemicals that eat into the fabric of the plate. It is often impossible to remove the color using nail polish remover gel. Dark spots on the nails will disappear when a healthy plate grows.

Intrinsic disease factors

If the toenail turns black, the person may have a fungal infection. Less commonly, the fungus affects the hands. A disease accompanied by a fungal infection and a darkening of the color of the plate is called melanonychia. The disease affects groups of people with reduced immunity:

• pregnant women;
• actively growing children;
• boys, girls in puberty.

The fungus is common in people with chronic, hard-to-treat diseases that lower the tone of the immune system, such as HIV/AIDS. When affected by a fungal infection, the blackening of the nail plate begins with the nail roller, spreading to the center of the plate.

Melanonychia is characterized by the fact that when a healthy plate grows, the abnormal color remains.
