The appearance of your nails can reveal a lot about your health. Healthy nails should be smooth and shiny without pits or grooves on the surface. They should be uniform in colour, except for the lunula, which is the half-moon-shaped part of the nail directly above the cuticle that is slightly lighter in colour. However, changes in nail shape, texture, or colour can sometimes indicate an underlying health condition. For example, nails with a bluish tint can mean the body isn't getting enough oxygen, which could be a sign of a lung problem or heart problems.

What You'll Learn
Healthy nails are shiny and smooth
Nail changes are common and can affect the shape, colour, texture and growth of your nails. Most nail changes are nothing to worry about, but some abnormalities could indicate a medical problem. For example, nails with a bluish tint can mean the body isn't getting enough oxygen, which could indicate a lung problem or a heart problem. If the nail surface is rippled or pitted, this may be an early sign of psoriasis or inflammatory arthritis. Dry, brittle nails that frequently crack or split have been linked to thyroid disease.
If you notice any changes in the appearance or texture of your nails, it can be a sign that you need treatment. However, most of the time, the issue only impacts your nails and doesn't indicate anything more serious. If you have concerns about your nail health, see your doctor or a dermatologist.

Rippled or pitted nails could be a sign of psoriasis
Healthy nails should be smooth and shiny without pits or grooves on the surface. They should be uniform in colour and thick and strong, but not so thick that they feel inflexible or petrified. However, if your nails are rippled or pitted, this may be an early sign of psoriasis or inflammatory arthritis. Psoriasis is a skin condition that causes red, flaky, crusty patches of skin covered with silvery scales. It can affect any part of the body, including the nails. If you notice any changes in the appearance or texture of your nails, it's important to see a doctor or dermatologist as it could indicate an underlying health condition.
Nail psoriasis can manifest in several ways, including pitting, which appears as small indentations or pits in the nail surface. Rippled nails, also known as nail ridging, can also be a sign of psoriasis. Other nail changes associated with psoriasis include nail thickening, yellow or brown discolouration, and separation of the nail from the nail bed. These changes can affect one or more nails and can vary in severity.
If you notice rippled or pitted nails, it's important to see a dermatologist for an accurate diagnosis. They may examine your nails and ask about any other symptoms you're experiencing. In some cases, they may also perform a skin biopsy or take a nail clipping to confirm the diagnosis. Treatment for nail psoriasis aims to improve the appearance of the nails and reduce inflammation. Topical medications, such as corticosteroids or vitamin D analogues, are often used to treat mild to moderate nail psoriasis. For more severe cases, oral medications or injectable biologics may be prescribed.
While rippled or pitted nails can be a sign of psoriasis, it's important to note that nail changes can have various causes, including nutritional deficiencies, thyroid disease, fungal infections, and ageing. Therefore, if you notice any changes in your nails, it's always best to consult a healthcare professional for proper evaluation and treatment.

Yellowish nails could be a sign of a fungal infection
Healthy nails should be smooth and shiny without pits or grooves on the surface. They should be uniform in colour, except for the lunula, which is the half-moon-shaped part of the nail directly above the cuticle that is slightly lighter in colour. However, if your nails are shiny and yellowish, this could be a sign of a fungal infection.
Fungal nail infections are a common problem that can affect people of all ages. The medical term for a fungal nail infection is onychomycosis. It usually starts as a white or yellow spot under the tip of your fingernail or toenail. As the infection goes deeper, the nail can become discoloured, thickened, and start to crumble at the edge. It might also cause pain and a slightly foul smell.
Fungal nail infections can be caused by various fungi, including yeasts and moulds. They tend to thrive in warm, damp environments, such as sweaty shoes or shared shower floors. You're more likely to get a fungal nail infection if you have a weakened immune system, diabetes, or poor circulation.
If you think you have a fungal nail infection, it's important to see a doctor or dermatologist for proper diagnosis and treatment. Over-the-counter antifungal creams and ointments are usually the first line of treatment. In more severe cases, oral antifungal medications or nail removal may be necessary.
