Diabetes is a long-term metabolic condition in which blood glucose remains higher than the healthy range because the body does not produce enough insulin, does not use insulin effectively, or both. With the right treatment plan, regular monitoring and lifestyle measures, many people with diabetes can maintain good glucose control and reduce the risk of complications.
This practical guide by Dr. Moxit Shah, DM Endocrinology explains the basics of Diabetes, important tests, treatment options, monitoring and everyday habits that matter in long-term diabetes care.
What Is Diabetes?
Diabetes mellitus includes several conditions, including type 1 diabetes, type 2 diabetes, gestational diabetes and specific forms caused by other diseases, medications or genetic conditions. Type 2 diabetes is the most common form and is often associated with insulin resistance and progressive reduction in insulin secretion.
Common Symptoms of Diabetes
Some people have no symptoms and are diagnosed during routine blood testing. Possible symptoms include increased thirst and frequent urination, increased hunger, unexplained weight loss, tiredness, blurred vision, slow healing of wounds and recurrent infections. Symptoms can vary considerably, and the absence of symptoms does not rule out diabetes.
How Is Diabetes Diagnosed?
Current 2026 American Diabetes Association diagnostic criteria include an HbA1c of 6.5% or higher, fasting plasma glucose of 126 mg/dL or higher, 2-hour plasma glucose of 200 mg/dL or higher during a 75-g oral glucose tolerance test, or random plasma glucose of 200 mg/dL or higher when accompanied by classic symptoms of hyperglycemia or a hyperglycemic crisis. When there is no unequivocal hyperglycemia, abnormal results generally need confirmation.

What Is HbA1c and Why Is It Important?
HbA1c provides an estimate of average blood glucose over roughly the previous 2–3 months. It is an important tool for diagnosis and ongoing monitoring, but it does not show day-to-day glucose variation or every episode of hypoglycemia. Conditions that affect red blood cell turnover or certain hemoglobin variants can also affect HbA1c interpretation.
How Is Diabetes Treated?
Diabetes treatment should be individualized according to the type of diabetes, glucose levels, cardiovascular and kidney health, weight-related goals, age, risk of hypoglycemia, other medicines and personal preferences.
1. Lifestyle Management
- Choose balanced meals with appropriate portions of carbohydrate, protein, vegetables and healthy fats.
- Prefer minimally processed foods and increase dietary fibre where appropriate.
- Reduce sugar-sweetened beverages and excess refined carbohydrates.
- Build regular physical activity into the week, according to your health status.
- Prioritize adequate sleep and stress management.
- Avoid tobacco and keep alcohol intake within medically appropriate limits.
2. Diabetes Medicines
Depending on the individual situation, treatment may include metformin, GLP-1 receptor agonists or dual GIP/GLP-1 receptor agonists, SGLT2 inhibitors, DPP-4 inhibitors, sulfonylureas, thiazolidinediones and/or insulin. The choice should be based on clinical indications, expected benefits, adverse effects, kidney function, cardiovascular or heart-failure considerations, cost and patient preferences.
For more information, read our guide to metformin benefits, side effects and dosing considerations.
3. Insulin
Insulin is essential in type 1 diabetes and is also used in many people with type 2 diabetes when insulin production is insufficient, glucose levels are markedly elevated, or other treatment approaches are inadequate or temporarily unsuitable. Insulin should be started and adjusted under appropriate medical supervision.
How Often Should Blood Sugar Be Checked?
Monitoring depends on the treatment plan. HbA1c is commonly assessed at least twice a year when glucose is stable and more frequently, often around every 3 months, when treatment has changed or glucose goals are not being met. People using insulin or at risk of hypoglycemia may benefit from structured self-monitoring or continuous glucose monitoring (CGM). CGM metrics such as time in range, time above range and time below range can provide additional information in appropriate patients.
What Complications Can Diabetes Cause?
Persistently elevated glucose can affect multiple organs. Important complications include diabetic kidney disease, diabetic eye disease and vision loss, peripheral neuropathy, foot ulcers and infection, cardiovascular disease and peripheral arterial disease.
Symptoms such as burning, tingling, numbness or pain in the feet should not be ignored. Read our article on diabetic neuropathy and burning or tingling feet.
Can Diabetes Be Reversed?
The answer depends on what is meant by “reversal.” Some people with type 2 diabetes can achieve remission with substantial and sustained improvement in weight, nutrition, physical activity and appropriate medical treatment. However, remission is not the same as a permanent cure, and glucose levels can rise again. Type 1 diabetes requires lifelong insulin replacement.
When Should You See an Endocrinologist?
An endocrinology consultation can be useful when diabetes is newly diagnosed, glucose remains above target despite treatment, there are recurrent episodes of low blood sugar, multiple medicines are being considered, insulin is required, complications are present, or the diagnosis itself is uncertain.
At Vishuddha Endocrine Clinic, Ahmedabad, diabetes care is individualized with attention to glucose control, weight, thyroid and other endocrine conditions, cardiovascular risk and long-term complication prevention.
Key Takeaways
- Diabetes can occur with or without obvious symptoms.
- HbA1c, fasting glucose and other validated glucose tests help diagnose and monitor diabetes.
- Treatment is individualized and may include lifestyle measures, tablets, injectable medicines, insulin or combinations.
- Regular screening for kidney, eye, nerve and cardiovascular complications is an important part of diabetes care.
- Do not change or stop diabetes medicines without discussing it with your treating doctor.
