Discoloured Nails: Symptoms, Underlying Causes, And Treatment Options

Nails are frequently regarded as a window into the body's health or disease condition. Systemic factors that interfere with their normal growth cause them to exhibit a wide range of alterations in shape and growth.  

When your nails look different or simply discoloured nails, it usually means something has changed in them or around them. This change can appear in different ways, like turning yellow, getting darker, or having white spots.   

Yellow nails might happen because of a fungal infection, smoking, or certain health problems like psoriasis or issues with the thyroid. Darker nails could mean you hurt them, have a fungal infection, or, rarely, even skin cancer. White spots on your nails are often harmless but could mean you have bumped into them or do not have enough zinc or calcium.  

It is important to figure out why you are having discoloured nails so you can treat them properly. While some cases need a doctor's help, others can be fixed with lifestyle changes or stuff you can buy at the store. Keep reading to know the various reasons behind discoloured nails.

Discolouration Of Fingernail: Can Nails Show Signs Of Illness?  

Here are how nails can reflect signs of illness:  

1. Colour Changes 

Discoloured nails like yellowing, browning, or developing unusual hues like blue or green can hint at health issues. These changes often signal conditions like fungal infections, anaemia, liver problems, respiratory disorders, or even skin cancer.  

2. Texture Changes 

Changes in nail texture, such as becoming brittle, thickened, developing ridges, or showing pits, can signify underlying health concerns. For instance, thickened nails are common in fungal infections or psoriasis, while pitting may indicate conditions like psoriasis or alopecia areata.  

3. Shape Changes 

Variations in nail shape, like clubbing (enlargement and rounding of fingertips) or spooning (a concave shape), can point to potential health issues. Clubbing is associated with respiratory or cardiovascular diseases, iron deficiency anaemia, or liver disorders.  

4. Nail Bed Changes 

Observing abnormalities in the nail bed, such as dark lines (melanonychia) or red streaks (splinter haemorrhages), can raise concerns about conditions like melanoma, endocarditis, or psoriasis.  

5. Lesions Or Growth 

The presence of lesions, growths, or abnormalities around or under the nails, such as warts, cysts, or tumours, may indicate underlying skin conditions or, in severe cases, malignancies.

How Do You Treat Discoloured Nails?  

Treating discoloured nails involves addressing the root cause, which can vary depending on factors like fungal infections, trauma, or underlying health issues. Here are some strategies:  

1. Antifungal Solutions 

When fungal infections are the culprit, both over-the-counter and prescription antifungal treatments are available. These medications, available as creams, ointments, or oral tablets, eradicate the fungus responsible for the discolouration. Consistent application is key for effective treatment.   

2. Preventive Measures 

Safeguarding your nails against further harm is vital. This entails wearing protective gloves during activities prone to nail damage and resisting habits like nail-biting or picking, which can exacerbate discoloured nails.  

3. Optimal Nail Hygiene 

Upholding good nail care practices is paramount. This encompasses keeping nails clean and dry, regular trimming, and steering clear of harsh chemicals or products that might worsen the discolouration of nails.  

4. Managing Underlying Conditions 

If discoloured nails stem from underlying medical issues like psoriasis, thyroid disorders, or liver ailments, addressing these conditions is key to restoring nail health. This often involves medical interventions prescribed by healthcare professionals.  

5. Supplementary Support 

In cases where nutritional deficiencies contribute to discoloured nails, incorporating supplements or nutrient-rich foods containing essential elements like zinc or calcium may help improve nail condition.   

6. Dermatological Consultation 

For persistent or severe discoloured nails unresponsive to home remedies, seeking guidance from a dermatologist or healthcare provider is wise. They can conduct a thorough assessment, identify the underlying cause, and recommend tailored treatment strategies.

Dietitian’s Recommendation 

As a dietitian, I recommend maintaining a balanced diet to support healthy nails and address discolouration issues. Eating nutrient-packed foods in daily meals is also suggested to ensure you get essential vitamins and minerals. Foods like meat, seafood, nuts, and seeds, which are high in zinc, can strengthen nails and prevent discolouration. Iron-rich foods such as red meat, poultry, fish, beans, and fortified cereals are vital for avoiding pale or spoon-shaped nails caused by iron deficiency anaemia.   

Foods rich in calcium, like dairy products, leafy greens, and fortified foods, also play a role in overall nail health, preventing brittleness and white spots. Staying hydrated and limiting your sugary or processed foods intake is also essential, as these can harm nail health. By following a well-balanced diet, you can support healthy nails and reduce the likelihood of discolouration.

Darkened or discoloured nails could indicate injury or even skin cancer sometimes. White spots might be minor or show we need more nutrients. Understanding why nails change colour helps us treat them right, whether with medications, care, or medical advice. Keeping an eye on nail health and getting help is key to early detection of any underlying health issues.
