7 Major Causes of Nail Disorders

nail disorders

Our general health can be inferred from the condition of our nails, which is more than simply an aesthetic aspect. Changes in the strength, appearance, or texture of the nails may be an indication of a disease or deficiency. The causes of nail abnormalities can range from nutrient shortages to infections or systemic diseases. Let’s look at some typical causes of nail diseases given by the best dermatologist in Karachi, along with their signs and possible remedies.

1- Nutritional Deficiencies

A lack of vital nutrients is one of the main reasons for nail diseases. Protein, vitamin, and mineral deficits can result in brittle nails, slow growth, and discoloration. For instance, insufficient biotin, often known as vitamin B7, can lead to thin, fragile nails that are prone to breaking. Iron deficiency causes the disorder known as koilonychia, which is characterized by brittle, concave nails. Include a balanced diet high in vitamins A, C, E, and B-complex as well as minerals like zinc and iron to encourage strong nails.

2- Trauma and Injury

Injury or stress to the nails can result in several diseases. Repeated or hard impacts, such as chewing your nails, can cause nail abnormalities like ridges, white patches, or even nail plate detachment. Incorrect manicure procedures or overuse of nail tools can harm the nail bed and cause infections or ingrown nails. These problems can be prevented by avoiding such trauma and implementing good nail care habits. In addition to nail-biting, accidents and repetitive activities that strain the nails can also result in damage and injury.

3- Fungal Infections

Onychomycosis, a fungal infection of the nails, can be persistent and challenging to treat. Due to the warm and damp environment inside shoes, these diseases affect toenails more frequently than fingernails. Small incisions or gaps between the nail and nail bed might allow fungus spores to penetrate the nail bed.

Fungal infections can affect other nails if not treated, leading to a significant issue. It’s crucial to remember that fungal nail infections can take a long time to completely clear up, so patience is needed during therapy.

4- Bacterial Infections

Bacterial infections can affect the nails and the surrounding skin, resulting in a variety of nail ailments. A cut, hangnail, or other type of lesion is the most common way for germs to penetrate the skin around the nails, resulting in the common bacterial infection known as paronychia. In severe situations, pus may form in the red, swollen, and painful afflicted area.

Nail-biting, poor nail cleanliness, and exposure to filthy environments can all cause bacterial infections. It is essential to practice proper hand hygiene, refrain from biting or picking at the nails, and keep nail care supplies clean to prevent bacterial infections. Antibiotics, warm water soaks, and keeping the affected region dry and clean may all be used as treatments.

5- Systemic Diseases

A few systemic nail disorders can show symptoms by altering the look of the nails. Pitting, ridges, and discoloration can appear on the nails as a result of psoriasis, eczema, and lichen planus. Clubbing, a disorder where the fingers grow and the nails curl downward, may indicate underlying respiratory or cardiovascular conditions. Consult a healthcare practitioner for an assessment and appropriate management of any underlying issues if you detect major changes in your nails without a clear explanation.

6- Hormonal Imbalances

Hormonal imbalances can have a big impact on the health of your nails. Nail abnormalities are typically linked to thyroid problems like hypothyroidism and hyperthyroidism. Nails can become brittle, dry, and slow-growing due to hypothyroidism, which is characterized by an underactive thyroid gland. On the other hand, nails that are brittle, weak, or mushy may result from hyperthyroidism, an overactive thyroid gland. Nail thickness, brittleness, and texture may change in pregnant women. Women going through menopause could observe more ridges and dryness on their nails.

7- Medications and Treatments

As a side effect, some medications and therapies can cause nail problems. For instance, chemotherapy medications might make the nails brittle, discolored, or disconnected. Antibiotics, retinoids, and antimalarial medications, among others, can affect the condition of your nails. Nail alterations brought on by radiation therapy may be transitory or permanent. If you have nail issues while taking medication or receiving treatment, get advice from a healthcare professional at the Imam Clinic.


Nutritional deficiencies, physical harm, infections, systemic illnesses, hormonal imbalances, and drug side effects are just a few of the factors that might lead to nail disorders. To properly avoid and manage certain illnesses, it can be helpful to understand the underlying causes. If you see substantial changes in your nails, it’s essential to maintain proper nail hygiene, eat a balanced diet, and get medical help. By doing this, you may encourage robust nail growth and make sure that your nails continue to serve as reliable indications of your general health and well-being.
