Diabetes Doesn’t Hurt. That’s Why It’s So Easy to Miss.

Almost 4 million Poles have diabetes. One in four people over 60. Most complications can be largely prevented — if we notice the problem in time.

Diabetes is one of the oldest diseases known to humanity. Despite this, it is still often underestimated — because it doesn’t hurt.

There is no fever, no sharp pain, and no clear warning signal. High blood sugar silently damages blood vessels and nerves for years. Only when a heart attack, stroke, vision issues, or diabetic foot appear do many people discover they have been living with the disease for a long time.

Type 1 Diabetes — Symptoms That Appear Suddenly

Type 1 diabetes (about 10% of all cases) develops very quickly — usually within a few weeks. The immune system attacks the beta cells in the pancreas that produce insulin. When around 80–90% of these cells are destroyed, blood sugar levels rise sharply.

Common symptoms of type 1 diabetes:

• Intense thirst and drinking large amounts of fluids
• Frequent urination (including at night)
• Rapid weight loss despite normal or increased appetite
• Severe fatigue and weakness
• Blurred vision (“fog in front of the eyes”)
• Dry mouth and skin
• In children: bedwetting, irritability, abdominal pain

In severe cases, it can lead to diabetic ketoacidosis — a life-threatening condition that requires immediate hospitalization.

Unlike type 2, the symptoms of type 1 are typically clear and difficult to ignore.

Type 2 Diabetes — Silent and Insidious

Type 2 diabetes (about 90% of cases) develops over many years. At first, the pancreas produces large amounts of insulin, but the body stops responding to it properly (insulin resistance). Blood sugar rises slowly, often without obvious symptoms.

This is why so many people only find out they have diabetes during routine tests or when complications already appear.

Modern Treatment — How Do GLP-1 Drugs Work?

One of the biggest breakthroughs in treating type 2 diabetes recently is GLP-1 receptor agonists (such as semaglutide and tirzepatide).

How do GLP-1 drugs work?

These medications mimic the natural hormone GLP-1, which is released in the intestines after eating. They work on several levels at once:

Real-world effects:

• Weight loss of 10–20% (even more with tirzepatide)
• Significant improvement in blood sugar control
• Protection for the heart and kidneys
• Reduced risk of heart attack and stroke

Thanks to these medications, many patients can lower their blood sugar and meaningfully improve problems related to obesity.

What Happens in the Body When Blood Sugar Stays High for Years?

Excess glucose primarily damages two types of cells:

1. Endothelial cells (inner lining of blood vessels) Glucose enters these cells in large amounts and creates free radicals. The blood vessels start to “rust” from the inside, accelerating atherosclerosis and increasing the risk of heart attack and stroke.
2. Nerve cells Excess glucose leads to the production of sorbitol (a type of alcohol), which draws water into the cells. Nerves swell and stop functioning properly. This causes tingling, numbness, and loss of sensation — especially in the feet (diabetic neuropathy).

The combination of neuropathy and damaged blood vessels creates the dangerous condition known as diabetic foot.

Final Thoughts

Type 1 diabetes usually causes clear, sudden symptoms. Type 2 diabetes develops silently over many years and is easy to miss.

Thanks to modern medications — especially GLP-1 drugs — we now have much better tools to control the disease and prevent complications. However, the most important factor remains early detection and consistent daily care.
