Pregnancy induces a wide range of physiological and hormonal changes that can significantly affect the health and appearance of the nails. While many women experience faster nail growth due to increased levels of oestrogen and improved circulation, these same factors can also lead to increased brittleness, splitting, and a higher risk of ingrown toenails. In the United Kingdom, where managing foot comfort is essential during the later stages of pregnancy, understanding these changes allows expectant mothers to implement safe and effective care routines. Most pregnancy-related nail issues are temporary and resolve after childbirth, but consistent hygiene and protective measures are necessary to prevent discomfort and localised infections during this period.

Hormonal influences on nail growth and brittleness
Hormonal fluctuations during pregnancy, particularly the rise in oestrogen, often result in nails growing much faster than usual. While this can be a positive change for some, for others, the rapid production of keratin cells can lead to a nail plate that is less dense and more prone to damage. This accelerated growth cycle can result in nails that are thin, soft, or brittle, making them more likely to peel at the tips or develop vertical splits.
The increased porosity of the nails during this time means they may absorb water more easily, which contributes to the wet and dry cycle that weakens the keratin bonds. The NHS website highlights that hormonal changes during pregnancy can affect the hair and nails, often causing them to become more brittle or to grow at an unusual rate. Applying a gentle moisturiser or a dedicated nail oil can help to stabilise the moisture levels in the nail plate and provide some protection against these hormonal effects.
Oedema and the risk of ingrown toenails
In the second and third trimesters, many pregnant women experience oedema, which is the swelling of the feet and ankles caused by increased fluid retention and pressure from the growing uterus on the veins. This swelling can significantly alter the fit of footwear and the relationship between the toenail and the surrounding skin. When the skin of the nail fold is swollen, it can bulge over the edge of the nail plate, making it much easier for the nail to pierce the soft tissue.
This mechanical pressure is a primary cause of ingrown toenails during pregnancy. If the nails are also brittle or incorrectly trimmed, the risk of a sharp edge causing a wound is further increased. Ensuring that footwear is wide enough to accommodate the swelling and avoiding tight hosiery are essential clinical steps to prevent this painful condition. Monitoring the toes for any signs of redness or tenderness during the daily hygiene routine is vital for catching an ingrown edge before it becomes a significant problem.
Nutritional demands and nail integrity
Pregnancy places significant nutritional demands on the body, as essential vitamins and minerals are prioritised for the development of the foetus. If the intake of certain nutrients such as biotin, iron, or calcium is insufficient to meet both the mother’s and the baby’s needs, the health of the nails may suffer. Brittle, thin, or concave nails can sometimes be a clinical marker of an underlying nutritional deficiency that requires investigation.
Maintaining a balanced diet is fundamental for supporting the production of strong keratin. While most women take prenatal vitamins, the physical state of the nails can still be affected by the body’s metabolic shifts. Clinical knowledge summaries suggest that a healthy diet and proper hydration are key components of managing skin and nail changes during pregnancy. If nail brittleness is severe or accompanied by extreme fatigue, it is important to discuss these symptoms with a midwife or GP to ensure that iron levels and overall nutritional status are optimal.
Practical grooming adjustments for expectant mothers
As pregnancy progresses, physical changes can make it more difficult for women to reach their feet for regular nail maintenance. This can lead to nails becoming too long, which increases the risk of them snagging on socks or being pushed into the skin by footwear. It is often safer to file the nails regularly rather than using clippers, as filing allows for a smoother finish and reduces the risk of shattering brittle keratin.
If trimming is necessary, doing so after a short lukewarm bath can help to soften the nails, but they should be dried thoroughly immediately after. For women who can no longer safely reach their toes, seeking assistance from a partner or a professional podiatrist is a safe clinical choice. Maintaining a consistent length and smoothing any rough edges prevents the mechanical trauma that leads to ingrown nails and secondary infections, ensuring that foot comfort is maintained throughout the final weeks of pregnancy.
Identifying signs of infection in the prenatal period
It is important to monitor the nails and surrounding skin for any signs of fungal or bacterial infection. Fungal infections, which cause thickening and yellow discolouration, can be more common due to the increased moisture and warmth around the feet during pregnancy. Bacterial infections, such as paronychia, can develop if an ingrown nail or a deep split becomes contaminated. Signs of infection include spreading redness, warmth, throbbing pain, or the presence of pus.
If an infection is suspected, it is essential to seek clinical advice before using any over-the-counter medicated treatments, as some antifungal lacquers or creams may not be recommended for use during pregnancy. A healthcare professional can provide a safe and effective treatment plan that protects both the mother and the baby. Early intervention ensures that a localized nail problem does not escalate into a more serious soft tissue infection that could affect mobility and overall wellbeing.
Professional podiatry and mid-term care
For pregnant women with a history of nail problems or those who develop significant foot discomfort, a review by a professional podiatrist is highly recommended. A podiatrist can provide professional nail maintenance and offer expert advice on footwear and pressure relief specifically tailored to the changes in weight and gait that occur during pregnancy. They can also safely manage any ingrown nails or thickened keratin without the risk of accidental injury.
Professional oversight is particularly beneficial during the third trimester when the risk of oedema and mechanical trauma is at its highest. Regular clinical reviews ensure that the feet remain healthy and that the nails are managed in a way that supports the body’s changing needs. Seeking professional help for foot and nail care allows expectant mothers to focus on their pregnancy while ensuring that their physical comfort and foot health are preserved during this demanding time.
Conclusion
Pregnant women are more prone to brittle nails and ingrown toenails due to hormonal changes, increased fluid retention, and nutritional shifts. Faster nail growth and oedema create a specific set of mechanical challenges that require consistent hygiene and protective care. Using gentle grooming techniques and monitoring for signs of infection are essential for maintaining nail health during this period. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
Will my nails return to normal after I give birth?
Most women find that their nails return to their pre-pregnancy state within a few months as hormonal levels and nutritional demands stabilise.
Is it safe to have a professional pedicure while pregnant?
Yes, provided the salon follows strict hygiene standards and you ensure that the technician does not cut your cuticles or use harsh chemicals.
Why are my fingernails peeling more than usual?
This is often due to the increased growth rate and hormonal shifts that make the keratin layers less cohesive and more prone to splitting.
Can I use a nail hardener if my nails are very weak?
It is generally safer to use a nourishing nail oil; if you wish to use a hardener, check the label to ensure it does not contain harsh chemicals.
Should I avoid wearing heels to protect my toenails?
Wearing flat, supportive shoes with a wide toe box is much better for preventing the pressure that causes ingrown nails and bruising.
Can I use antifungal cream for a nail infection while pregnant?
You must consult a GP or pharmacist before using any medicated treatments to ensure they are safe for use during pregnancy.
Is it normal for my cuticles to feel drier during pregnancy?
Yes, the body’s increased demand for hydration can leave the skin around the nails feeling dry and more prone to hangnails.
