Introduction: 

Diabetes is a long-term medical disorder defined by increased blood glucose levels. It can result in a number of health issues if not controlled. This article clarifies the symptoms, available tests, and potential repercussions of diabetes with the goal of increasing awareness of this widespread global health issue.

Diabetes symptoms:

1. Frequent Urination and Excessive Thirst:

Diabetes symptoms include frequent urination and excessive thirst because high blood sugar levels force the body to try to eliminate extra glucose through urination.

2. Unexplained Weight Loss or Gain:

Inadequate usage of glucose for energy commonly results in frequent weight changes, either loss or gain.

3. Extreme Fatigue:

Low glucose levels might leave you feeling weak and exhausted all the time.

4. Blurred vision: 

Excess hyperglycemia can harm the lens of the eye, impairing vision.

5. Delay in Wound Healing: 

Diabetes can hinder the body's capacity to repair and renew cells, which leads to a delay in wound healing.

Diabetes Diagnosis:

1. Blood Glucose tests :

• Fasting Plasma Glucose (FPG) test:

Measures blood sugar levels after an overnight fast.

• Oral Glucose Tolerance Test (OGTT): Assesses blood sugar levels prior to and following consumption of a beverage high in glucose. 

• Hemoglobin A1c (HbA1c) Test: This test gives the average blood sugar level for the previous two to three months.

2. Clinical Assessment of Symptoms:

Assessing signs and symptoms such excessive thirst, frequent urination, and unexplained weight changes helps with the diagnosis.

3. Physical examinations:

 Spotting issues with diabetes-related skin diseases, obesity, and high blood pressure.

Diabetes has the following negative effects:

1. Cardiovascular Complications: 

Diabetes greatly raises the risk of heart disease, stroke, and high blood pressure.

2. Neuropathy: 

Diabetes can harm nerves, resulting in tingling, discomfort, and numbness, especially in the limbs.

3. Nephropathy:

 Prolonged blood sugar elevations can harm kidneys and even cause renal failure.

4. Retinopathy:

 Diabetes can harm the retina's blood vessels, causing vision issues and even blindness.

5. Complications of the feet: 

Diabetes can affect the nerves and blood supply to the feet, raising the risk of infections and ulcers.

Conclusion: 

The effects of diabetes must be prevented and managed by prompt diagnosis, adequate treatment, and lifestyle adjustments. To effectively manage this chronic illness, regular monitoring, a balanced diet, regular exercise, and adherence to prescribed medications are necessary. For the best advice and treatment strategies, consult with medical professionals that specialize in providing care for diabetics.
