Could you have diabetes without knowing it? Discover the main symptoms.
Introduction
Diabetes mellitus, often simply referred to as diabetes, is one of the fastest-growing diseases worldwide. Many people live with the disease for years without knowing it, as symptoms often appear gradually and are easily overlooked. However, a late diagnosis can have serious health consequences.
In this article, you’ll learn about the warning signs that may indicate diabetes, why early diagnosis is so important, and how to assess your risk.
Why diabetes is so dangerous
Diabetes isn’t just a “sugar disease.” If not properly treated, it can damage virtually every organ in the body. The most common complications include:
Heart problems such as heart attack or stroke
Kidney damage up to kidney failure
Vision loss (diabetic retinopathy)
Nerve damage with numbness or pain
Increased risk of infection as the immune system is weakened
This damage often develops over years – which is why it is crucial to detect the disease as early as possible.
Typical symptoms of diabetes
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:
Obesity (especially belly fat)
Lack of exercise
