Diabetes is a heterogeneous condition that can present in different forms and with different underlying mechanisms. From autoimmune type 1 diabetes, to type 2 diabetes linked to lifestyle, through to gestational diabetes, MODY diabetes, and other types, each form requires a personalized approach. In all cases, controlling blood glucose levels is essential to prevent complications and preserve quality of life.

Diabetes mellitus is a chronic disease that results from an excess of glucose in the blood (hyperglycemia) due to a disruption in the production or action of insulin.

There are several recognized types of diabetes:

• Type 1 diabetes: an autoimmune disease that requires insulin treatment from the time of diagnosis.

• Type 2 diabetes: the most common form, associated with genetic factors and lifestyle factors such as obesity and physical inactivity.

• Gestational diabetes: appears during pregnancy.

• MODY diabetes: rare forms of genetic origin.

• Other types of diabetes: such as those secondary to pancreatic diseases or associated with certain medications.

The diagnosis of diabetes is made through blood tests that assess:

• Fasting blood glucose values

• Glycated hemoglobin (HbA1c)

• Oral glucose tolerance test

Normal blood glucose values:

• Fasting: 70-99 mg/dl.

• Postprandial​​​​​​​ (2 hours after an oral glucose load): < 140 mg/dl.

Persistently elevated blood glucose levels (especially above 160-180 mg/dL over several days) can cause three classic symptoms, known as the "3 Ps":

• Polyuria (increased urination)

• Polydipsia (excessive thirst)

• Weight loss

Other symptoms of diabetes that may serve as warning signs include:

• Constant hunger

• Blurred vision

• Fatigue​​​​​​​

• Frequent infections

• Slow wound healing

The treatment of diabetes depends on the type of diabetes and the specific needs of each patient. At barnaclínic+, we combine the most advanced treatment options with individualized, multidisciplinary follow-up.

Treatment of type 1 diabetes

· Intensive insulin therapy using multiple daily injections (MDI) with insulin pens.

· Continuous subcutaneous insulin infusion (CSII) via insulin pumps or hybrid closed-loop systems.

· Either of the two previous modalities are accompanied by the use of continuous glucose monitoring systems (sensors or CGM).

· Immunotherapy in early stages of the disease.

· Diabetes education focuses on providing the knowledge, skills, and attitudes needed to adapt and improve metabolic control throughout the different stages of diabetes (onset, treatment change, onset of complications, etc.).

· Psychological and nutrition support tailored to the patient's profile.

Treatment of type 2 diabetes

· Medical nutrition therapy and regular physical activity.

· Oral or injectable medications (GLP-1, SGLT2, etc.).

· Insulin therapy with or without continuous glucose monitoring.

· In selected patients, diabetes remission may be achieved through intensive lifestyle changes and sustained weight loss.

Treatment of gestational diabetes

· Strict nutritional and glycemic control.

· Physical activity adapted to pregnancy.

· Insulin in cases that are not controlled by diet alone.

· Coordinated follow-up by a multidisciplinary team including gynecologists and endocrinologists
