Diabetes type 2 warning: Do your nails look like this? The lines you shouldn’t ignore

Diabetes is a common condition that affects more than four million people in the UK, and 90 per cent of all cases are caused by type 2 diabetes. The condition is caused by the pancreas not producing enough of the hormone insulin, or the body not reacting to insulin. Without enough insulin, the body struggles to convert sugar in the blood into useable energy. You could be at risk of diabetes symptoms if your fingernails have a distinctive line across them, it’s been revealed.

Healthy nails appear smooth and have consistent colouring


Depressions across the fingernails could be caused by uncontrolled blood sugar levels, according to medical website Healthline.

The condition is known as Beau’s lines, and they’re described as indentations that run from one side of the nail to the other.

The lines are caused by medical conditions that cause a disruption in nail plate growth.

“Healthy nails appear smooth and have consistent colouring,” said the medical website.

“As you age, you may develop vertical ridges, or your nails may be a bit more brittle.

“Certain medical conditions can also change the appearance of your fingernails.

“Depressions that run across your fingernail are called Beau’s lines. These can be a sign of malnourishment.

“Other conditions that cause Beau’s lines are diseases that cause a high fever such as measles, mumps, and scarlet fever, peripheral vascular disease, pneumonia, uncontrolled diabetes, and a zinc deficiency.”

Meanwhile, you could also be at risk of diabetes if you have a condition known as Terry’s nails, it added.

Terry’s nails describes where the tip of each nail has a dark band spread from one side to the other.

The condition could also be caused by liver disease, or even congestive heart failure, it said.

Many people may have diabetes without even knowing it, as the symptoms don’t necessarily make you feel unwell.

Common diabetes symptoms include passing more urine than normal, blurred vision, and having cuts or wounds that take longer to heal than normal.

Speak to a doctor if you’re worried about the symptoms of diabetes, or if you think you may be at risk. Diagnosing the condition early is crucial, as diabetes raises the risk of heart disease and strokes.

You could lower your risk of the condition by eating a healthy, balanced diet, and by doing regular exercise.

Everyone should aim to do at least 150 minutes of moderate-intensity activity every week.
