Horizontal ridges or bumps on your nails are usually harmless but can sometimes be a sign of an underlying health condition or previous injury. They can be caused by nail trauma, such as slamming your finger in a door or dropping something heavy on your foot. Horizontal ridges can also be caused by malnutrition or nutritional deficiencies, such as a zinc deficiency. In some cases, they may indicate a more serious condition, such as peripheral vascular disease, diabetes, hypothyroidism or Raynaud's disease.

Malnutrition
Horizontal ridges or bumps on your nails are usually harmless but can sometimes be a sign of an underlying health condition. They are often caused by a condition called Beau's lines, which can be the result of nail trauma, such as slamming your finger in a door or dropping something heavy on your foot. Beau's lines can also be caused by peripheral vascular disease, diabetes, hypothyroidism, Raynaud's disease, chemotherapy, or a severe illness with a high fever, such as COVID-19, measles, or pneumonia.
In addition to these causes, horizontal ridges on your nails can also be a sign of malnutrition or certain nutritional deficiencies. For example, zinc deficiency can cause Beau's lines and white spots on your nails, while iron deficiency can cause vertical nail ridges and koilonychia (spoon nails). Malnutrition can lead to a deficiency in essential nutrients, such as zinc and iron, which are necessary for nail health.
Nails are made of a protein called keratin, which is also found in hair and skin. When the body is malnourished, it may not be able to produce enough keratin, leading to nail abnormalities. In addition, malnutrition can cause a decrease in the production of nail cells, resulting in slower nail growth and thinner nails. This disruption in nail growth can lead to the formation of horizontal ridges or bumps on the nails.
Certain vitamins and minerals are also essential for nail health. For example, biotin, a water-soluble vitamin, plays a crucial role in nail growth and strength. A deficiency in biotin can lead to brittle nails that are prone to breakage and ridging. Vitamin B12 and folic acid are also important for nail health, and a deficiency in these nutrients can result in nail changes, including horizontal ridges.
It is important to note that horizontal ridges on the nails can have various causes, and malnutrition is just one possible explanation. If you are concerned about the appearance of your nails, it is recommended to consult a healthcare professional or dermatologist, who can evaluate your individual case and provide appropriate advice or treatment options.

Nail injury
Horizontal ridges or bumps on your nails are usually harmless but can sometimes indicate a health condition or a previous injury to your nail. They are often caused by a condition called Beau's lines, which can be the result of nail trauma, such as slamming your finger in a door or dropping something heavy on your foot. Beau's lines can also be caused by nutritional deficiencies, such as a zinc deficiency, or by certain medical conditions, including peripheral vascular disease, diabetes, hypothyroidism, Raynaud's disease, and severe illnesses with high fevers, such as COVID-19, measles, or pneumonia.
Nail injuries can occur in various ways and can range from mild to severe. One common cause of nail injuries is nail biting, which can lead to nail bed damage and infections. Another common cause is accidentally hitting your finger or toe, which can result in a bruised, cracked, or even detached nail. In more severe cases, a nail injury can be caused by a crush injury, where the nail is completely torn off or severely damaged. This type of injury often requires medical attention and may even require surgery to repair the nail bed and surrounding tissues.
Certain activities and habits can also increase the risk of nail injuries. For example, people who work with their hands a lot, such as construction workers or gardeners, may be more prone to nail injuries due to the nature of their work. Additionally, those who participate in contact sports, such as boxing or football, are also at a higher risk of sustaining nail injuries. Wearing protective gear, such as gloves or proper footwear, can help reduce the risk of nail injuries during these activities.
Nail injuries can have various symptoms, depending on the severity of the injury. Minor nail injuries may only cause temporary pain and discomfort, while more severe injuries can result in intense pain, swelling, and bleeding. In some cases, the nail may become discoloured, indicating possible bruising or infection. If left untreated, nail injuries can lead to more serious complications, such as nail deformities, infections, or even permanent nail loss. Therefore, it is important to take nail injuries seriously and seek medical attention if necessary.
To prevent nail injuries, it is important to take certain precautions. This includes wearing protective gear during activities that may pose a risk to your nails, such as gardening gloves or proper footwear. Additionally, maintaining proper nail care can help strengthen your nails and reduce the risk of injuries. This includes keeping your nails trimmed and filed smoothly, as well as moisturising your nails and cuticles regularly to prevent dryness and brittleness. Overall, being mindful of potential hazards and taking the necessary precautions can help reduce the risk of nail injuries and maintain the health of your nails.

Beau's lines
Horizontal ridges or bumps on your nails are usually due to a condition called Beaus lines. These bumps may happen when something interrupts your nail growth. Possible causes include:
- Chemotherapy
- Damage from using artificial or acrylic nails or getting gel manicures for long periods
- Nail trauma, such as slamming your finger in a door or dropping something heavy on your foot
- Peripheral vascular disease (PAD)
- Severe illness with high fever, such as COVID-19, measles or pneumonia
- Certain nutritional deficiencies, such as zinc deficiency, which can also cause white spots on your nails
Beaus lines are characterised by grooves or indentations running across the nail. You may have a single groove on a single nail or one or more grooves on all your nails. Horizontal nail ridges usually develop when nail growth is disrupted by something. Conditions that interfere with blood flow to the nail, including peripheral vascular disease, diabetes, hypothyroidism and Raynaud’s disease, can also cause Beaus lines.

Peripheral vascular disease
Horizontal ridges on your nails can be harmless, but they can also be a sign of peripheral vascular disease (PAD). This is a condition that interferes with blood flow to the nail. Other causes of horizontal nail ridges include malnutrition, nail injury, and certain nutritional deficiencies, such as zinc deficiency.
There are two main types of PVD: functional and organic. Functional PVD is caused by a problem with the way the blood vessels work, such as a blockage or a narrowing of the arteries. Organic PVD is caused by a structural problem with the blood vessels themselves, such as a tear or a rupture.
Risk factors for PVD include age, smoking, high blood pressure, high cholesterol, diabetes, and a family history of the disease. It is important to see a doctor if you experience any symptoms of PVD, as early diagnosis and treatment can help to prevent serious complications.
Treatment for PVD aims to improve blood flow to the affected area and prevent further damage to the blood vessels. This may include lifestyle changes, such as quitting smoking, eating a healthy diet, and exercising regularly. Medications may also be prescribed to lower cholesterol or blood pressure, or to improve blood flow. In some cases, surgery may be necessary to open up blocked arteries or to repair damaged blood vessels.

Zinc deficiency
Horizontal ridges on nails can be a sign of zinc deficiency. Zinc is a mineral that is required for the body's essential functions. A zinc deficiency can be caused by a diet high in phytate-containing whole grains, foods grown in zinc-deficient soil, or processed foods containing little or no zinc. It can also be caused by problems absorbing zinc from your diet, or by not consuming enough zinc in your diet.
Severe zinc deficiency may disturb the sense of smell and taste. Night-blindness may be a feature of severe zinc deficiency, although this usually occurs in combination with other nutritional deficiencies. Zinc deficiency can also cause behavioural abnormalities, such as irritability, lethargy, and depression.
