Thick toenails can be caused by a variety of factors, including fungal infections, psoriasis, and injuries to the nail bed. If left untreated, these infections can worsen and cause discomfort when wearing shoes or walking. While some people opt for self-treatment using professional-grade toenail clippers, incorrect cutting can lead to ingrown toenails, cut skin, or the spread of the fungus. Therefore, it is recommended to consult a podiatrist for guidance on proper cutting techniques and to address any underlying conditions. In some cases, a podiatrist may advise topical treatments, oral medications, or surgical removal to address the issue.

Thick toenails can be a symptom of fungal infections, older age, psoriasis, or other medical conditions
Thick toenails can be a cosmetic and health issue. They can be difficult to trim and may cause pain or discomfort, especially when wearing shoes. Thick toenails can be a symptom of several conditions, including:
Fungal Infections
Also known as onychomycosis, toenail fungus is a common cause of thick toenails. It can make the nail thick, brittle, and discoloured, with a yellow, green, or brown hue. The infection affects the nail bed, and the nail matrix may thicken in response to remove the fungal infection. Fungal infections can be treated with antifungal medications prescribed by a podiatrist.
Older Age
As people age, their toenails naturally thicken and become more susceptible to fungal infections. Older adults are more likely to experience thick toenails, and age is a significant factor to consider.
Psoriasis
Psoriasis is a skin condition that can affect toenails, causing them to become thick, pitted, and discoloured. It can lead to abnormal thickening and growth of the toenails and may cause the nail to turn yellow or brown.
Other Medical Conditions
Various medical conditions can influence nail growth and thickness. Poor circulation, associated with diabetes or peripheral artery disease, can lead to thicker toenails due to inadequate blood flow to the nail bed. Additionally, certain thyroid disorders and hereditary factors can contribute to thick toenails.
If you have thick, twisted toenails that are difficult to cut, it is advisable to consult a podiatrist or a foot specialist. They can examine your feet, diagnose the underlying cause, and provide appropriate treatment options, such as conservative treatment with regular debridement (filing) of the toenails or, in severe cases, permanent toenail removal.

Toenail fungus can cause discolouration and thickening of the nail
Thick and twisted toenails can be unsightly and uncomfortable. If you are struggling to cut your toenails, you may want to consider seeking professional advice. A podiatrist or chiropodist is a trained professional who can help with nail care and offer advice on preventing and managing nail problems. They can also provide guidance on cutting techniques and recommend suitable tools and products.
Toenail fungus is a common issue that can cause discolouration and thickening of the nail. It is often characterised by a yellow, white, or brown hue, and the nail may appear chalky or cloudy in some spots. This discolouration is caused by a fungal infection that affects the toenails, known as onychomycosis or tinea unguium. The fungus gets between the toenail and the nail bed, the tissue underneath, leading to separation and thickening of the nail.
Fungal infections are a common cause of nail discolouration and thickening. Onychomycosis, a type of fungal infection, is a frequent culprit. It can result in nails becoming thick, yellow, and streaky, with white spots. Tinea unguium, caused by a type of mould called a dermatophyte, is the most prevalent nail fungal infection. It primarily affects toenails but can also impact fingernails.
In addition to fungal infections, other factors can contribute to nail thickening and discolouration. Ageing is a common factor, with older individuals being more susceptible to toenail fungus. Certain medical conditions, such as psoriasis, diabetes, and athlete's foot, can also increase the likelihood of nail fungus and subsequent thickening and discolouration.
Mycotic nails are another type of fungal infection that can affect both toenails and fingernails. It causes the nail to separate from the nail bed, resulting in thickness and fragility. The nail may exhibit discolouration, appearing brownish, whitish, or blackish. Yeast onychomycosis, often caused by Candida, is a type of mycotic nail infection that typically affects fingernails and may indicate a weakened immune system.
To address thick and discoloured toenails caused by fungal infections, it is important to seek professional advice. A healthcare provider can diagnose the specific type of nail fungus and recommend appropriate treatment options. Proper nail care, including regular trimming and maintaining good hygiene, can help manage the condition and prevent further complications.

Thick toenails may be difficult to cut and require a larger clipper
Thick toenails can be unsightly and uncomfortable. They may appear rough, ridged, or scaly on the surface and take on a yellow, green, or brown hue. Toenails may thicken over time due to a fungal infection, older age, psoriasis, or other factors.
If you have thick toenails, it is important to practice proper nail care to prevent further complications. Thick toenails may be difficult to cut and often require a larger clipper designed specifically for toes. It is recommended to have separate clippers for your fingers and toes to reduce the risk of transferring bacteria or fungus.
Before cutting your toenails, soak your feet in warm water for at least 10 minutes to soften the nails. Then, thoroughly dry your feet and nails with a towel. Make small cuts with the toenail clipper to avoid splintering and cut straight across, avoiding rounding off the corners to prevent ingrown nails. Use an emery board to smooth any sharp edges.
If you have thickened toenails that are painful or difficult to cut safely, it is advisable to seek professional help. Consult a doctor or healthcare professional for guidance, especially if you suspect a fungal infection or underlying medical condition. They can recommend appropriate treatments based on the cause of the thickened nails.
Additionally, consider preventative measures to avoid nail thickening. Keep your hands and feet moisturized to prevent cracks, and treat any cuts or skin issues promptly. When engaging in activities like dishwashing, wear gloves to protect your nails. Choose well-fitting shoes and ensure your socks and shoes remain dry. These simple steps can help maintain healthy nails and prevent thickening.

Soak your feet in warm water to soften thick toenails before cutting
Thick toenails can be caused by fungal infections, older age, psoriasis, and other factors. They can become rough, ridged, or scaly, and may take on a yellow, green, or brown hue.
If you have thick toenails, it is important to cut them with care. Before cutting, it is recommended to soak your feet in warm water for at least 10 minutes to soften the nails. You can also add apple cider vinegar or white vinegar to the water, as suggested by Dr. Waldman, as vinegar has antifungal properties. After soaking, thoroughly dry your feet and toenails with a towel.
When you are ready to cut your nails, use a nail clipper designed for toes, as they are broader and thicker than fingernails and require a larger clipper. Make small cuts to avoid splintering the nail, and cut straight across. Avoid rounding off the corners to lessen the chance of the nail becoming ingrown.
If your thickened toenails are painful or you feel you cannot safely cut them by yourself, consult a doctor or a podiatrist for advice and assistance. They can help you manage your nail health and provide guidance on proper cutting techniques.

If you have painful thick toenails, consult a podiatrist or dermatologist for advice
Thick toenails can be challenging to cut and may be a symptom of an underlying condition. Toenail fungus is a common cause of thick nails, but other factors include fungal infections, older age, psoriasis, and injuries. If you have thick toenails that are painful, it is recommended that you consult a podiatrist or dermatologist for advice and treatment.
Podiatrists are specialists in foot care and can provide professional advice on how to manage and treat thick toenails. They may recommend specific cutting techniques or tools, such as using nail clippers designed for thicker toenails, soaking your feet in warm water before cutting, and filing your nails with an emery board to smooth sharp edges. Podiatrists can also help identify any underlying conditions that may be contributing to the thickness of your toenails and provide appropriate treatment options.
Dermatologists are doctors who specialize in skin, hair, and nail conditions. They can examine your thick toenails using a dermatoscope, a handheld instrument, and may take nail clippings or swabs for further diagnosis. Dermatologists can provide expert advice on treating thick toenails and addressing any underlying skin or nail conditions. They may recommend antifungal medications or other treatments to improve the health of your toenails.
If you are experiencing pain due to thick toenails, it is important to seek professional help. Do not attempt to cut your toenails at home if you are unsure or uncomfortable, as it can worsen the condition. Consult a podiatrist or dermatologist, who can provide personalized advice and treatment options to manage your thick toenails effectively and safely.
Additionally, to prevent further complications, it is recommended to use separate nail clippers for your fingers and toes to reduce the risk of transferring bacteria or fungus. It is generally advised to cut your toenails before showering, as dry nails are less likely to bend or tear, resulting in a cleaner cut. However, for individuals with very thick toenails, cutting them after a shower may be easier due to the softened state of the nails.
