Understanding the Different Types, Symptoms, Diagnosis, and Treatment
Diabetes mellitus is a chronic medical condition that affects how your body uses glucose (blood sugar), the body’s main source of energy. When diabetes is not properly managed, high blood sugar levels can damage the heart, kidneys, eyes, nerves, and blood vessels. Fortunately, early diagnosis, healthy lifestyle choices, regular medical care, and appropriate treatment can help most people live long, healthy, and active lives.
At Norvinia Health, Dr. Mamta Ojha provides personalized, evidence-based diabetes care focused on prevention, early diagnosis, and long-term health.
What Is Diabetes?
Glucose comes from the foods you eat and is carried through the bloodstream to your body’s cells. Insulin, a hormone produced by the pancreas, allows glucose to enter the cells and be used for energy. Diabetes develops when the body either does not produce enough insulin or cannot use insulin effectively, causing blood sugar levels to rise.
Types of Diabetes
Type 1 Diabetes
Type 1 diabetes is an autoimmune disease in which the immune system attacks the insulin-producing cells of the pancreas. People with Type 1 diabetes produce little or no insulin and require lifelong insulin therapy. Although it commonly develops during childhood or adolescence, it can occur at any age.
Type 2 Diabetes
Type 2 diabetes is the most common form, accounting for approximately 90–95% of all diabetes cases. It develops when the body becomes resistant to insulin or gradually loses its ability to produce enough insulin. Risk factors include excess weight, physical inactivity, family history, increasing age, high blood pressure, high cholesterol, and a history of gestational diabetes.
Prediabetes
Prediabetes occurs when blood sugar levels are higher than normal but not high enough to meet the criteria for diabetes. Without lifestyle changes, many people with prediabetes eventually develop Type 2 diabetes. Early intervention can significantly reduce this risk.
Gestational Diabetes
Gestational diabetes develops during pregnancy, usually between 24 and 28 weeks of gestation. Although blood sugar often returns to normal after delivery, both mother and baby have an increased risk of developing Type 2 diabetes later in life. Careful monitoring and treatment during pregnancy are important for a healthy pregnancy and delivery.
Less Common Types
Some people develop diabetes due to inherited genetic conditions, diseases affecting the pancreas, certain hormonal disorders, or medications such as long-term corticosteroids. These forms are less common but require individualized evaluation and treatment.
Common Symptoms
Many people with diabetes have few or no symptoms in the early stages. When symptoms occur, they may include:
Increased thirst
Frequent urination
Increased hunger
Fatigue
Blurred vision
Slow-healing cuts or wounds
Frequent infections
Numbness or tingling in the hands or feet
Unexplained weight loss, especially in Type 1 diabetes
If you experience these symptoms, schedule a medical evaluation promptly.
How Is Diabetes Diagnosed?
Diabetes can be diagnosed using one or more laboratory tests:
Hemoglobin A1c (HbA1c) of 6.5% or higher
Fasting plasma glucose of 126 mg/dL or higher
Two-hour oral glucose tolerance test of 200 mg/dL or higher
Random blood glucose of 200 mg/dL or higher with classic symptoms
People at increased risk should be screened regularly, even if they feel healthy.
Treatment and Management
Modern diabetes care focuses on more than lowering blood sugar. Current guidelines emphasize preventing heart disease, kidney disease, stroke, and other long-term complications while improving quality of life.
Treatment is individualized and may include:
Healthy nutrition with balanced meals and portion control
Regular physical activity (at least 150 minutes of moderate exercise each week)
Weight management
Smoking cessation
Blood sugar monitoring when appropriate
Diabetes education and self-management support
Oral medications such as metformin
Injectable medications including GLP-1 receptor agonists
SGLT2 inhibitors for selected patients with diabetes, heart disease, heart failure, or chronic kidney disease
Insulin therapy when necessary
Recent guidelines recommend selecting medications based not only on blood sugar levels but also on cardiovascular health, kidney function, body weight, and individual patient goals.
Preventing Diabetes Complications
Good diabetes control greatly lowers the risk of serious complications. Regular follow-up care should include:
HbA1c testing every 3 to 6 months
Blood pressure monitoring
Cholesterol management
Annual kidney function testing
Comprehensive foot examinations
Yearly dilated eye examinations
Recommended vaccinations
Regular dental care
Managing stress, getting adequate sleep, and taking medications consistently are also important components of diabetes care.
Can Type 2 Diabetes Be Prevented?
Many cases of Type 2 diabetes can be prevented or delayed through healthy lifestyle changes.
Helpful strategies include:
Maintaining a healthy weight
Exercising regularly
Eating more vegetables, fruits, whole grains, legumes, and lean protein
Limiting sugary drinks and processed foods
Sleeping 7–9 hours each night
Avoiding tobacco products
Research shows that losing just 5–10% of body weight can substantially reduce the risk of developing Type 2 diabetes in people with prediabetes.
