What You'll Learn

Red lines on nails are likely to be blood lines
Red lines on nails are likely to be blood vessels or streaks of blood under the nails, known as splinter haemorrhages. They are called splinter haemorrhages because they resemble having a splinter underneath the nail. They occur when blood leaks or swells from small blood vessels that run up and down the nail bed. They can be caused by trauma to the nails, such as dropping something on them or hitting them against something. They can also be caused by certain drugs or medical conditions, including nail psoriasis, infection of the heart valves (endocarditis), vessel damage from swelling of the blood vessels (vasculitis), or tiny clots that damage the small capillaries (microemboli). In some cases, they may indicate an underlying health problem. However, treatment is usually not needed unless there is an underlying condition.

They are caused by splinter haemorrhages
Red lines on nails are likely to be blood lines and are probably caused by splinter haemorrhages. Splinter haemorrhages are the result of blood leakage from the small blood vessels on the nail bed. They can be perfectly harmless, but in some cases, they may be caused by an underlying condition. If you have had an injury to the nail, this is the likely cause of the splinter haemorrhage. However, if you don't remember any cause for the injury, it may be an underlying illness and, in this case, it would be better to seek advice from your doctor. The potential conditions causing a splinter haemorrhage are wide-ranging and include antiphospholipid syndrome, which is when blood clots develop, both in the arteries and the veins. They could also be a symptom of lupus or infectious endocarditis, which is a sign of an underlying infection.

Potential conditions include antiphospholipid syndrome or lupus
Red lines on nails are called splinter hemorrhages. They are caused by blood leaking or swelling from small blood vessels that run up and down the nail bed. They can be the result of trauma to the nails, such as dropping something on them, hitting them against something, or getting them stuck in an obstacle. They can also be caused by tiny blood clots known as microemboli in the capillaries.
Potential conditions that may cause splinter hemorrhages include antiphospholipid syndrome or lupus. Antiphospholipid syndrome is an autoimmune disorder that can cause blood clots in small blood vessels, such as those found in the nail bed. Lupus is also an autoimmune disorder that can cause inflammation and damage to blood vessels, leading to blood leaking from the vessels and causing splinter hemorrhages.
It is important to note that red lines on nails can also be a sign of infection, particularly of the heart valves (endocarditis). In such cases, the splinter hemorrhages may be caused by vessel damage from swelling of the blood vessels (vasculitis) or tiny clots that damage the small capillaries (microemboli).
If you notice red lines on your nails, it is recommended to consult a healthcare professional to determine the underlying cause and receive appropriate treatment.
