Could you have diabetes without knowing it? Discover the main symptoms

Although the signs of type 1 and type 2 diabetes can differ, there are some common symptoms that should definitely be taken seriously:

1. Constant thirst (polydipsia)

When your body has too much sugar in your blood, it tries to excrete it through urine. This leads to fluid loss and intense thirst.

2. Frequent urination (polyuria)

A classic warning sign: those affected have to go to the toilet several times during the night.

3. Unexplained weight loss

Especially in type 1 diabetes, sudden, severe weight loss occurs, even if you eat normally or even more.

4. Extreme fatigue

Because the body’s cells can’t absorb the sugar properly, energy is lacking. This leads to tiredness, listlessness, and exhaustion.

5. Blurred vision

High blood sugar levels change the fluid balance in the eye and temporarily impair vision.

6. Frequent infections

Fungal infections, urinary tract infections, or poorly healing wounds can be a sign of diabetes.

7. Tingling and numbness

Nerve damage (neuropathies) is noticeable through tingling in the hands and feet.

Non-specific but important signs

Many symptoms are not immediately obvious and can be confused with other conditions. These include:

Night sweats

Headaches and dizziness

Difficulty concentrating

Dry skin and itching

Risk factors for diabetes

Certain factors increase the likelihood of developing type 2 diabetes:
