Toenails play an important role in protecting the soft tissue beneath them and keeping the tips of your toes safe. While it is normal for toenails to grow slower than fingernails, it is not normal for them to stop growing. Toenails may stop growing due to several factors, including trauma to the nail, nutritional deficiencies, medical conditions such as diabetes, peripheral artery disease (PAD), chemotherapy, fungal infections, and physical damage to the nail matrix. Poor circulation in the lower extremities can also lead to slow or stopped toenail growth as it reduces the supply of oxygen and nutrients crucial for healthy growth.
| Characteristics | Values |
|---|---|

What You'll Learn
Poor circulation
Toenails that aren't growing could be a sign of an underlying vascular disorder called peripheral artery disease (PAD). PAD occurs when plaque builds up on the insides of arteries, preventing blood from flowing freely throughout the body. Other signs of PAD include poor leg hair development and skin changes on the legs and feet.
While slow toenail growth can be a normal part of aging, it can also indicate an underlying health issue such as diabetes, nutritional deficiencies, or peripheral artery disease. Toenails that aren't growing properly may also be a result of trauma to the nail, such as dropping an item on the foot or wearing improper footwear.
If you notice that your toenails aren't growing, it's important to seek medical attention. A doctor can help determine the underlying cause and recommend appropriate treatment options. In some cases, healthy toenail growth may be restored with proper treatment.
It's worth noting that toenail growth can be affected by various factors, including injuries, illnesses, and medications. Certain types of fungus can also infect the toenails, causing thick, yellow, cracked, or cloudy nails. While slow toenail growth may not always be a cause for concern, it's important to be vigilant and consult a doctor if you have any concerns or if the condition persists.

Peripheral artery disease (PAD)
Toenails that have stopped growing can be a sign of Peripheral Artery Disease (PAD). PAD is a vascular disorder that affects the arteries, causing reduced blood flow throughout the body. This can lead to impaired circulation, particularly in the legs and feet, resulting in slow or halted toenail growth. While slow toenail growth can have various causes, including trauma, injury, or fungal infections, it is important to seek medical attention to identify any underlying health issues.
Poor circulation associated with PAD can lead to a range of symptoms, including changes in the toenails. Toenails may become brittle, thin, and more susceptible to damage and infections. In some cases, the toenails may stop growing completely due to severely compromised circulation. It is important to note that while toenail growth typically slows down with age, the cessation of toenail growth can indicate underlying health issues, including PAD.
If you notice that your toenails have stopped growing or are growing slower than usual, it is recommended to consult a medical professional. A vascular expert can assess your symptoms, perform diagnostic tests, and provide appropriate treatment options for PAD if it is identified as the underlying cause. Early intervention is crucial in managing PAD and preventing further complications.
While PAD can have a significant impact on individuals, there are effective treatment options available. These may include lifestyle modifications, such as a healthy diet and regular exercise, as well as medical interventions, such as medication or surgical procedures, to improve blood flow and manage symptoms. Seeking medical advice is essential to receiving a proper diagnosis and developing a tailored treatment plan for PAD.

Diabetes
People with diabetes are more prone to toenail infections with yeasts or fungi. Onychomycosis, a type of fungal infection, is more common in toenails due to their slower growth rate, reduced blood supply, and occlusive footwear. Discoloration is often the first noticeable change in diabetic patients' toenails, with most exhibiting some yellowing of the nails, though shades can vary. Discoloration may start at the distal edge and spread to the root of the nail bed. In some cases, yellowing can indicate a nail infection.
The nail plate may separate or become distorted (onychogryphosis), leading to misshapen toenails. Thickened toenails can be challenging to manage, potentially resulting in deformities like a Ram's Horn or ingrown toenail. Additionally, impaired circulation may cause localized hypertrophy of the nail plate, and diabetic patients may experience periungual blisters, haemorrhages, and ulcerations.
To prevent complications and maintain foot health, it is crucial for individuals with diabetes to wear well-fitting shoes and monitor any changes in their toenails. Regularly checking for cuts, sores, and toenail issues is essential, as nerve damage from diabetes can make it difficult to feel injuries, increasing the risk of infection. Seeking the care of a podiatrist to help manage toenail health and diabetes is strongly recommended.

Nutritional deficiencies
Toenails are made from keratin, the same protein that makes up your skin and hair. They play an important role in protecting the soft tissue beneath them and keeping the tips of your toes safe. While it is normal for toenails to grow slower than your fingernails, it is not normal for them to stop growing. Slow toenail growth can be a sign of nutritional deficiencies or other underlying health issues.
Vitamin B7, also known as biotin, plays a crucial role in nail health. It is involved in the production of keratin, the protein that makes up nails. A deficiency in biotin can lead to brittle, thin, or splitting nails that may also appear dull or discolored. In addition to nutritional deficiencies, biotin deficiency can also result from conditions that affect nutrient absorption, such as inflammatory bowel disease or celiac disease. Supplementation with biotin has been shown to improve nail thickness and reduce brittleness associated with its deficiency.
Vitamin A is essential for maintaining healthy nails. It helps in the production of new nail cells and keeps the nails moisturized, preventing dryness and brittleness. A deficiency in vitamin A can lead to nail abnormalities, including slow nail growth, ridged nails, and nail breakage. Including vitamin A-rich foods in your diet, such as carrots, sweet potatoes, and dark leafy greens, can help ensure adequate intake and promote healthy nail growth.
Zinc is a mineral that plays a vital role in nail health. It is involved in the formation of keratin and contributes to the strength and integrity of nails. A deficiency in zinc can lead to nail changes, including slow nail growth, white spots on the nails, and nail ridging. Ensuring adequate zinc intake through dietary sources, such as meat, seafood, and nuts, or through supplementation, can support healthy nail growth and prevent deficiencies.
In addition to addressing nutritional deficiencies, it is important to maintain proper nail care practices. Keeping your toenails trimmed, cleaning them regularly, and wearing proper-fitting footwear can help prevent nail trauma and reduce the risk of infections, which can also contribute to slow nail growth. If slow toenail growth persists despite addressing nutritional deficiencies and practicing proper nail care, it is advisable to consult a healthcare professional to rule out any underlying health conditions that may be contributing to the issue.

Trauma to the nail
After a nail matrix injury, you may experience bruising, ridges, or discolouration. In some cases, the nail may fall off. It is important to note that toenails are more susceptible to fungal infections when they are injured, as fungi thrive in warm, wet environments created by shoes and socks. Toenail fungus is also contagious and can be contracted from walking barefoot in places like a locker room. Symptoms of toenail fungus include yellow or dark discolouration, brittleness, and thickening of the nails. While treatments are available, it can take up to 18 months for the fungus to grow out.
To prevent further damage to your nails, it is recommended to keep your toenails short, avoid biting or picking at them, and wear protective gear when doing housework or gardening. Moisturising your nails and cuticles regularly can also help keep them healthy and flexible. Look for lotions or oils containing ingredients like jojoba oil, vitamin E, or shea butter.
In most cases, toenails will grow back after trauma, although it may take several weeks to a year or more for regrowth to occur. The rate of regrowth depends on various factors, including the severity of the injury, age, overall health, and hormones. Proper medical care is crucial for nail regrowth, and in rare cases, the nail matrix may be permanently damaged, preventing the nail from growing back.
