Understanding Nail Conditions / Nail Disorders

Nail problems can be caused by many things, including fungal infections, bacterial infections, skin conditions like eczema or psoriasis, nutritional deficiencies, or injuries to the nail. In West Africa, fungal infections are especially common because of the warm, humid climate and frequent exposure to moisture. Sometimes nail changes can also be linked to other health conditions in the body, so it is worth seeing a doctor if you are unsure.

Mild nail problems — like a small cut near the nail or minor dryness — can sometimes be managed at home by keeping the area clean, dry, and moisturised. However, if the nail is discoloured, thickening, painful, or showing signs of infection such as swelling or pus, it is best to see a doctor rather than relying on home remedies. Home treatments like soaking in salt water or applying local herbs may not be strong enough to clear an infection and could delay proper treatment.

Treatment depends on what is causing the nail problem. Fungal nail infections are usually treated with antifungal medicines — either creams applied directly to the nail or tablets taken by mouth for more stubborn cases. Bacterial infections may need antibiotic treatment, and some nail conditions linked to skin or health problems are managed by treating the underlying cause. Your doctor will recommend the right treatment for your specific situation.

You can reduce your risk of nail infections by keeping your nails clean, short, and dry, and by wearing footwear in public places like bathrooms, markets, and swimming areas. Avoid sharing nail clippers, files, or shoes with other people, as infections can spread this way. If your hands or feet are often wet due to your work, try to dry them thoroughly and use protective gloves where possible.

Yes, sometimes changes in your nails can be a sign that something else is going on in your body. For example, very pale nails can be linked to anaemia, yellow nails may sometimes be connected to lung or liver problems, and pitting or crumbling nails can be a sign of a skin condition called psoriasis. This is one of the reasons it is important to see a doctor if your nail problem does not have an obvious cause — they can check whether your nails are trying to tell you something about your overall health.
