Type 2 Diabetes: 4 Foot Sensations That May Signal High Blood Sugar

Type 2 diabetes is a chronic condition in which unstable blood sugar levels can cause damage throughout the body.
Typically, these complications often concentrate in the feet. There are four sensations in the feet that may indicate high blood sugar levels — a sign of type 2 diabetes.

In the early stages, diabetes symptoms are usually mild, so many people don’t pay much attention.

If you notice a wound, see a doctor immediately.

However, when blood sugar levels rise to a dangerous level, the body begins to suffer more serious harm. Acute symptoms tend to appear later — and they often show up in the feet.

Professor Andrew Boulton, President of the International Diabetes Federation, explained that there are several signs suggesting something may be wrong with a diabetic person’s feet.

“At first, there’s just a feeling that something isn’t quite right. Then come sensations such as numbness, tingling, pins and needles, or a crawling feeling — sometimes burning or extreme cold,” he told Express.

What other symptoms may appear in the feet?

Professor Boulton noted that other warning signs include dry skin, calluses on the balls of the feet, and foot wounds.
Among these, he emphasized that wounds are the greatest concern — if you see one, you should seek medical attention immediately (Express).

Because it can be difficult to examine your own feet, you can use a mirror to check the soles, or ask someone to help. In addition, foot temperature can also serve as a warning sign, Professor Boulton added. Check whether your feet feel unusually warm to the touch.

What Causes High Blood Sugar Levels?

For someone with type 2 diabetes, there are two main causes:
either the pancreas doesn’t produce enough insulin, or the insulin produced isn’t properly used by the cells.

Insulin is a hormone that regulates blood sugar levels.
Without proper insulin function, blood sugar can rise uncontrollably.

Essentially, blood sugar isn’t inherently bad — it provides vital energy for cells to function.
However, when blood sugar remains high for a long time, it can damage the body and lead to several complications, such as foot problems and an increased risk of heart disease, according to Express.

What Should You Do?

The main response to persistently high blood sugar is to change unhealthy lifestyle habits.
Two key factors play the biggest role in blood sugar control: diet and exercise.

People with diabetes should limit certain foods and follow these recommendations:

• Eat a variety of foods — including fruits, vegetables, and small portions of starchy foods

• Keep sugar, fat, and salt intake to a minimum

• Have three regular meals daily — don’t skip breakfast, lunch, or dinner.
