Nails May Turn Yellow, Brown, Green, or White – Causes, Diagnosis, and Treatment at Emirates Hospitals Group

Changes in nail color, such as turning yellow, brown, green, or white, can indicate an underlying health condition. In some cases, nails may also become brittle, thickened, or crumbly, leading to discomfort or cosmetic concerns. Discoloration can result from infections, systemic diseases, or repeated exposure to chemicals. Seeking medical evaluation at Emirates Hospitals Group can help identify the cause and provide the right treatment.

Causes of Nail Discoloration

• Fungal Infections (Onychomycosis): A common cause of yellow, brown, or white nails, often accompanied by thickening and brittleness.
• Bacterial Infections: Greenish nails may indicate a bacterial infection, particularly Pseudomonas bacteria.
• Psoriasis and Eczema: These skin conditions can affect nail color and structure, causing white patches, pitting, or separation from the nail bed.
• Smoking or Chemical Exposure: Nicotine, nail polish, or cleaning chemicals can stain nails yellow or brown.
• Liver or Kidney Disease: Systemic conditions can cause nail discoloration, such as white nails in liver disease or half-white, half-brown nails in kidney disease.
• Vitamin and Mineral Deficiencies: Iron deficiency can cause pale or white nails, while zinc or biotin deficiencies may lead to discoloration.
• Diabetes and Circulatory Issues: Poor circulation can cause nails to appear discolored and slow to grow.

Diagnosis of Nail Discoloration

A medical evaluation at Emirates Hospitals Group may include:

• Physical Examination: Assessing nail color, shape, and texture.
• Fungal and Bacterial Tests: Nail clippings or cultures may be analyzed for infections.
• Blood Tests: Checking for underlying conditions like liver disease, diabetes, or nutritional deficiencies.

Treatment for Discolored Nails

Treatment depends on the cause and may include:

• Antifungal or Antibiotic Medications: Topical or oral treatments for infections.
• Lifestyle Adjustments: Avoiding smoking, harsh chemicals, and improving nail hygiene.
• Nutritional Supplements: Addressing deficiencies with iron, zinc, or biotin.
• Medical Procedures: In severe cases, laser therapy or nail removal may be required.

For persistent nail discoloration, a consultation at Emirates Hospitals Group is recommended to prevent complications and restore healthy nails.
