Purple nails can be a sign of trauma to the nail or finger, such as a strong blow or heavy object falling on the finger. They can also be caused by circulatory problems, unsuitable footwear, or systemic diseases such as diabetes. Purple nails can also be a sign of cyanosis, which is caused by a lack of oxygen in the blood. This can be due to various health conditions that affect the respiratory and cardiovascular systems, including heart and lung diseases.

What You'll Learn
Trauma to the nail or finger
Purple nails are usually the result of trauma to the nail or finger, such as a strong blow or a heavy object falling on the finger. This type of injury can cause damage to the blood vessels under the nail, leading to bleeding that gets trapped between the nail bed and the nail plate. Recognisable symptoms of this type of injury include dark red or purple discolouration of the nail, throbbing pain, and possible swelling in the surrounding area.
Purple nails can also be a sign of cyanosis, which is caused by a lack of oxygen in the blood. This type of discolouration can also occur on other parts of the body, including the hands, fingertips, toes, nose, lips, tongue, and skin around the eyes. Cyanosis can be more challenging to detect in people with darker skin tones, as the discolouration may appear grey or white. It is important to note that anyone with blue or purple nails should seek medical advice, as it can indicate various health conditions affecting the respiratory and cardiovascular systems.
In addition to trauma and cyanosis, purple nails can also be caused by wearing unsuitable footwear, such as tight shoes that put pressure on the nails during physical activity or long walks. Poor circulation and systemic diseases, such as diabetes, can also predispose individuals to developing nail problems due to an increased risk of infections. These haematomas can be particularly painful due to the accumulation of blood. However, unless there is also damage to the skin or bones, a subungual haematoma is rarely a cause for concern.

Poor circulation
Purple nails can be a sign of poor circulation. This is because poor circulation can cause cyanosis, which is when the blood does not carry enough oxygen to the fingertips. This can cause the nail beds to turn blue or purple. Other symptoms of cyanosis include discolouration around the lips, tongue, palms of the hands and soles of the feet. It is more common in people with darker skin tones.
Purple nails can also be caused by trauma to the nail or finger, such as a strong blow or a heavy object falling on the finger. They can also be caused by wearing unsuitable footwear, such as tight shoes that put pressure on the nails during physical activity or long walks.
In some cases, purple nails may be a symptom of an underlying health condition, such as diabetes. This is because diabetes can predispose individuals to developing nail problems due to poor circulation and an increased risk of infections. However, unless there is also damage to the skin or bones, a subungual haematoma is rarely a cause for concern.

Problems with haemoglobin
Dark purple nails can be a sign of a lack of oxygen in the blood, which can be caused by problems with haemoglobin. Haemoglobin is a protein in red blood cells that is responsible for carrying oxygen around the body. If there is a problem with haemoglobin, it can result in a condition called cyanosis, which causes a bluish-purple discolouration of the nails, skin, lips, and tongue. This discolouration can also occur on other parts of the body, including the hands, fingertips, toes, and nose.
It is important to note that dark purple nails can be a symptom of more serious underlying health issues. Therefore, anyone experiencing this discolouration should seek medical advice to determine the cause and receive appropriate treatment.
