What is Type 2 Diabetes
Type 2 diabetes is a metabolic disease characterized by an increase in blood glucose levels.
Normally, insulin allows glucose from the blood to enter cells, where it is used to produce energy. In type 2 diabetes, insulin resistance develops, which means that cells no longer respond efficiently to its action.
As a result, glucose remains in the blood and blood glucose levels rise.
Common Symptoms of Type 2 Diabetes
Symptoms of type 2 diabetes can appear gradually and may sometimes be mild. Among the most common manifestations are:
Excessive Thirst
Intense thirst is one of the common symptoms of diabetes. Elevated blood glucose causes the body to eliminate more water through urine, which can lead to dehydration and the onset of thirst.
Frequent Urination
People with diabetes may notice they urinate more frequently, including during the night. This occurs because the kidneys attempt to eliminate excess glucose from the blood.
Fatigue
Persistent fatigue is another possible symptom. When glucose cannot be used efficiently by cells, the body does not produce sufficient energy.
Blurred Vision
Elevated blood glucose levels can temporarily affect the lens of the eye, causing blurred vision.
Slow Wound Healing
In people with diabetes, wounds and cuts may heal more slowly. Impaired circulation and elevated blood glucose levels can slow the healing process.
Recurrent Infections
Skin, urinary, or fungal infections may occur more frequently in people with diabetes.
Other Signs That May Appear
In addition to classic symptoms, some people may present other manifestations, such as:
- increased sensation of hunger
- tingling or numbness in the hands and feet
- dry skin
- dry mouth
- appearance of dark patches at skin fold levels (acanthosis nigricans)
These signs may suggest insulin resistance.
Risk Factors for Type 2 Diabetes
Certain people have a higher risk of developing type 2 diabetes.
Risk factors include:
- overweight or obesity
- sedentary lifestyle
- family history of diabetes
- arterial hypertension
- dyslipidemia (elevated cholesterol)
- age over 45 years
People who present these risk factors should have their blood glucose checked periodically.
How the Diagnosis is Established
The diagnosis of type 2 diabetes is based on blood tests that measure blood glucose levels.
The most common tests are:
- fasting blood glucose
- glycated hemoglobin (HbA1c)
- oral glucose tolerance test
The doctor will interpret the test results and establish the diagnosis.
The Importance of Early Diagnosis
Early detection of type 2 diabetes is very important because it allows treatment to begin and lifestyle changes to be adopted.
Blood glucose control reduces the risk of complications such as:
- cardiovascular disease
- kidney damage
- diabetic neuropathy (nerve damage)
- vision impairment
Conclusion
Type 2 diabetes can have subtle symptoms or may progress for a long period without obvious manifestations. Excessive thirst, frequent urination, fatigue, and recurrent infections are among the most common signs of this condition.
If you notice such symptoms or have risk factors for diabetes, it is recommended to perform the necessary tests and seek medical consultation.
Early diagnosis and appropriate treatment can contribute to maintaining good health and preventing long-term complications.
