What is diabetes?

Diabetes is a metabolic condition in which blood glucose levels remain persistently higher than normal. It results from insufficient insulin secretion, or insulin not working properly in the body.

Type 1 vs. type 2

Type 1 diabetes occurs when the pancreas's insulin-producing beta cells are destroyed, often by an autoimmune process, resulting in little to no insulin production β€” it typically develops in childhood or adolescence. Type 2 diabetes involves a combination of insulin resistance and relatively insufficient insulin secretion, is far more common in adults, and is closely linked to obesity, genetics, and lifestyle.

The role of insulin

Insulin is a hormone secreted by the pancreas that helps move glucose from the blood into cells, where it can be used for energy or stored. When insulin is insufficient or not functioning properly, glucose cannot enter cells and builds up in the blood, causing high blood sugar.

Common symptoms

Classic symptoms include excessive thirst, frequent urination, and weight loss despite eating more than usual. However, early type 2 diabetes often has no clear symptoms and is frequently discovered incidentally during a health checkup.

General diagnostic concept

Diagnosis combines results such as fasting blood glucose, an oral glucose tolerance test, and HbA1c (which reflects average blood sugar over the past 2–3 months). Specific diagnostic criteria and interpretation are made through a doctor's testing and judgment.

Complications and the importance of management

Prolonged poor blood sugar control can raise the risk of retinopathy, nephropathy, and neuropathy, as well as cardiovascular disease. If diabetes is suspected or diagnosed, it should be managed under a doctor's guidance.

What diabetes is

Diabetes is a leading chronic condition that, once diagnosed, often requires lifelong management, and its global prevalence continues to rise. This page provides general educational information; individual diagnosis and treatment must be done through a doctor's testing and prescriptions.

Its connection to fatty liver

Diabetes and fatty liver are closely interconnected, and insulin resistance is a known common factor affecting both conditions β€” improving one often helps the other, so it is worth watching both blood sugar and liver health together.

Frequently Asked Questions

Can diabetes be cured completely?

Type 1 diabetes usually requires lifelong insulin therapy rather than being "cured," while type 2 diabetes can improve significantly with weight loss and lifestyle changes in some cases β€” but whether it can be considered resolved and how to manage it varies by individual, so consult a doctor.

If I avoid sugary foods, will I avoid getting diabetes?

Simple sugar intake alone is not the only cause β€” genetics, obesity, and lack of exercise all play a role together, so avoiding sweets alone cannot be said to prevent diabetes.
