Red nails can be a sign of various health conditions and issues. Fingernails are made of a protein called keratin, and changes in their colour, shape, or texture can indicate an underlying health problem. Red nails could be a sign of possible heart disease, kidney issues, psoriasis, lupus, or gastrointestinal issues. Other causes of red nails include congested capillaries, arthritis, and melanoma. If you notice that your fingernails have turned red, it is important to consult a doctor or dermatologist to determine the exact cause and receive appropriate treatment.

Red nails could indicate an issue with the endocrine, neurological or gastrointestinal systems
Red nails can signify a variety of health issues, including problems with the endocrine, neurological, or gastrointestinal systems. While some causes are harmless, others can indicate more serious underlying conditions.
Red nails have been linked to specific health issues, including heart disease, kidney problems, and conditions like psoriasis and lupus. Heart failure, in particular, can cause the lunulae (the pale areas near the cuticle) to turn red, a condition called azure lunulae. This discoloration could be due to congested capillaries, which is also a possible sign of psoriasis.
Changes in nail color, such as redness, can be indicative of nutritional imbalances or deficiencies. For example, vitamin B12, iron, zinc, or magnesium deficiencies have been known to cause vertical ridges on the nail beds, which can lead to red lines on the nails. Maintaining a balanced diet and ensuring adequate nutrient intake can help address these deficiencies and improve nail health.
In addition to underlying health conditions, red nails can also result from external factors. Exposure to certain chemicals, such as detergents or nail polish remover, can cause nails to become thin or soft, making them more susceptible to breakage or tearing. This can sometimes lead to redness or inflammation around the nails.
If you notice persistent red nails or other concerning symptoms, it is important to consult a healthcare professional. They can provide a proper diagnosis and rule out any serious underlying conditions.

Red nails may be a sign of heart disease or kidney issues
Red nails can be a sign of several health conditions, and it is important to be aware of these potential issues. Firstly, red nails may indicate heart disease. Heart-related problems such as congestive heart failure can cause red nails, and this is a serious condition that requires medical attention. Additionally, red nails could be a sign of kidney issues, including renal failure or chronic kidney disease.
Lindsay's nails, also known as half-and-half nails, are characterised by a white or reddish-brown colour near the tip, with the rest of the nail appearing white or washed out. This type of nail discolouration is often associated with kidney disease, uremia, or acidosis due to impaired glomerular filtration. It is estimated that 20-50% of those with kidney disease exhibit Lindsay's nails, and it is more commonly observed on toenails than fingernails.
Another nail condition to be aware of is Terry's nails, which are typically white or washed-out nails with a thin, reddish-brown strip near the tip. While this can sometimes be a normal part of the ageing process, it can also indicate an underlying disease, such as liver disease or diabetes. It is important to note that stress can also cause nail discolouration, including reddish-brown strips, so it is not always indicative of a more serious condition.
Changes in nail colour, shape, or texture can be an early warning sign of underlying health issues. If you notice any sudden changes, it is important to consult a doctor as soon as possible. While some nail discolouration may be due to treatable infections or nutritional deficiencies, other colours can signal more serious conditions. For example, blue nails can indicate poor circulation or respiratory issues, while black or green nails may suggest bacterial infections or even cancer. Therefore, it is always best to seek medical advice for a proper assessment if you notice any unusual changes in your nail colour.

Red nails are associated with conditions like psoriasis and lupus
Red nails can be indicative of several health issues. One possible cause is lupus, a long-term autoimmune condition that occurs when the immune system attacks healthy tissue. Lupus can cause a variety of symptoms, including changes in the skin and nails, such as discoloration, infections, and changes in nail shape. Nail issues due to lupus can be painful and cause visible changes, such as redness and swelling, that may be a cause for concern and self-consciousness.
Another condition associated with red nails is psoriasis. Nail psoriasis, or psoriatic nail dystrophy, affects the nail matrix or nail bed, resulting in clinical changes in the nail. It can cause symptoms such as pitting, leukonychia, red spots in the lunule, onychorrhexis, and nail crumbling. Up to 35% of people with psoriasis will experience nail pitting.
It is important to note that changes in nail color can indicate a variety of health issues, including vitamin and mineral deficiencies, anemia, poor nutrition, kidney disease, liver disease, thyroid issues, or more serious conditions such as subungal melanoma, a dangerous form of skin cancer. Therefore, if you notice any sudden changes in the shape, strength, or color of your nails, it is recommended to consult a doctor as soon as possible to determine the underlying cause and receive appropriate treatment.
Additionally, certain lifestyle changes and medical treatments can help manage nail health and prevent further complications. For example, wearing comfortable shoes, avoiding nail-biting, and wearing gloves when handling chemicals can help reduce the risk of nail damage and infection. Eating a healthy diet rich in fruits, vegetables, whole grains, healthy proteins, and fats, while reducing processed foods, saturated fats, salt, and sugar, can also improve nail health by providing the necessary nutrients for strong nails.

Red nails could be a result of congested capillaries
Red nails can signify underlying health issues and should not be ignored. While healthy nails are typically smooth, clear, and strong, exhibiting no spots or discolouration, changes in colour, texture, or shape can indicate health problems. Red nails, specifically, could be a result of congested capillaries, which is also a possible sign of psoriasis.
Congested capillaries refer to the dilation and bursting of tiny blood vessels, resulting in the appearance of small red lines or spots on the skin. In the context of nail health, congested capillaries can cause the areas near the cuticle to turn red. This condition is often associated with psoriasis, an autoimmune disease that affects the skin and joints. Psoriasis causes skin cells to build up rapidly, forming thick, scaly patches that may be red or silver. It commonly affects the elbows, knees, scalp, back, face, palms, and feet, and its symptoms include nail pitting, thickening, and discolouration. Up to 35% of people with psoriasis experience nail changes, and these changes can provide valuable insights into a person's health.
While nail discolouration can sometimes be attributed to lifestyle factors or nail injuries, it is important to consult a medical professional if you notice any persistent or concerning changes. Red nails, in particular, can indicate potential problems with the endocrine, neurological, or gastrointestinal systems, as well as possible cancer or heart disease. Therefore, if you observe red nails, it is advisable to seek medical advice to rule out any underlying health issues.
Additionally, maintaining nail health is essential. This can be achieved by staying hydrated, consuming a well-balanced diet rich in vitamins and minerals, and avoiding exposure to chemicals such as detergents and nail polish remover, which can contribute to nail discolouration and brittleness.

Red-yellow discolouring, or 'oil drop' may indicate psoriasis
Red fingernails can be indicative of several health conditions. Reddish-yellow discolouration or an oil drop on the fingernails may indicate psoriasis, a common autoimmune skin condition that causes itchiness and discomfort. Psoriasis affects millions of people, with more than 3% of the US population suffering from it. It is characterised by patches of thick, scaly, discoloured skin. While there is no cure for psoriasis, treatment can help manage symptoms.
Nail psoriasis causes skin discolouration, pitting, and changes to your fingernails and toenails. Nails can often become loose and separate from the nail bed. In severe cases, nails may crumble. An oil drop, or oil spot, is a rare occurrence and usually presents in combination with other psoriatic nail phenomena. It appears as a reddish-brown, well-bordered spot, with a reddish-brown halo indicating its areal progression.
Psoriasis can manifest in several forms, including guttate, pustular, erythrodermic, and sebopsoriasis. Guttate psoriasis may appear after a sore throat caused by a streptococcal infection, and often affects children and young adults. Pustular psoriasis is characterised by small, pus-filled bumps on top of plaques. Erythrodermic psoriasis is a rare and severe form of psoriasis that affects a large area of the skin and requires emergency treatment. Sebopsoriasis typically appears on the face and scalp as greasy, yellow scales.
If you notice any sudden changes in the shape, strength, or colour of your nails, it is important to consult a doctor as soon as possible. While nail discolouration may be due to a treatable infection or vitamin deficiency, it could also indicate a more serious underlying health condition.
