What Is Diabetes Mellitus?

Understanding the definition, types, symptoms, complications, investigations, treatment, and lifestyle management of diabetes.

Diabetes mellitus is a group of chronic metabolic disorders characterized by persistently elevated blood glucose levels. It occurs when the body does not produce enough insulin, does not use insulin effectively, or both.

Insulin is a hormone produced by the pancreas that helps glucose move from the bloodstream into cells where it can be used for energy. Persistent hyperglycemia can affect blood vessels, nerves, kidneys, eyes, and other organs over time.

The Classification of Diabetes Mellitus

Clinical Classes

Diabetes Mellitus

Type 1 diabetes mellitus
Type 2 diabetes mellitus
Other specific types of diabetes
Gestational diabetes mellitus

Secondary Diabetes

Secondary diabetes may occur in association with pancreatic diseases, hormonal disorders, certain genetic conditions, medications, or other underlying medical conditions.

Gestational Diabetes Mellitus

Gestational diabetes mellitus (GDM) refers to diabetes diagnosed during pregnancy that was not clearly present before pregnancy. Appropriate screening, monitoring, and medical management during pregnancy are important for the health of both mother and baby.

Type 1 and Type 2 Diabetes

Type 1 Diabetes Mellitus

Type 1 diabetes occurs when the immune system destroys the insulin-producing beta cells of the pancreas. People with type 1 diabetes require insulin for survival and need regular medical monitoring.

Type 2 Diabetes Mellitus

Type 2 diabetes is commonly associated with insulin resistance and progressive impairment of insulin secretion. Risk factors can include excess body weight, physical inactivity, family history, increasing age and other metabolic factors.

Symptoms and Signs of Diabetes

Increased thirst
Frequent urination
Increased hunger
Unexplained weight loss
Fatigue
Blurred vision
Slow-healing wounds
Frequent infections
Tingling or numbness in the hands or feet

Pathophysiology of Diabetes Mellitus

Diabetes mellitus involves abnormalities in glucose metabolism caused by inadequate insulin production, impaired insulin action, or a combination of both. Persistent hyperglycemia can gradually damage blood vessels and nerves and may contribute to complications affecting the kidneys, eyes, cardiovascular system and other organs.

Investigations for Diabetes

Diabetes may be assessed using appropriate blood glucose testing and other investigations recommended by a healthcare professional.

Fasting plasma glucose
Post-meal or postprandial glucose
Random plasma glucose when clinically appropriate
HbA1c
Oral glucose tolerance test when indicated
Urine testing when clinically appropriate
Lipid profile and cardiovascular risk assessment
Kidney function and urine albumin assessment

Glycosylated Hemoglobin—HbA1c

HbA1c provides an estimate of average blood glucose over the preceding several months and is widely used for diagnosing and monitoring diabetes according to clinical guidelines.

Ketonuria and Ketones

Ketones may appear when the body is unable to use glucose effectively and starts breaking down fat for energy. Significant ketones, particularly when accompanied by high blood glucose, vomiting, abdominal pain, dehydration, or rapid breathing, require urgent medical assessment.

Complications and Risk Factors

Poorly controlled diabetes over time can increase the risk of complications involving the cardiovascular system, kidneys, eyes, nerves, and feet.

Diabetic Ketoacidosis

Diabetic ketoacidosis (DKA) is a serious medical emergency that occurs most commonly in type 1 diabetes but can occur in other circumstances as well.

Excessive thirst and urination
Nausea or vomiting
Abdominal pain
Dehydration
Rapid or deep breathing
Confusion or drowsiness
Fruity-smelling breath

Important: Symptoms suggesting diabetic ketoacidosis, severe dehydration, confusion, or very high blood glucose require urgent medical evaluation and should not be managed at home with self-medication.

Diabetic Nephropathy

Diabetes can affect the kidneys and may lead to albumin in the urine and progressive loss of kidney function.

Diabetic Retinopathy

Diabetic retinopathy affects the blood vessels of the retina and can cause vision problems or permanent visual loss if advanced. Regular eye examinations are important for people with diabetes.

Cardiovascular and Vascular Complications

Diabetes is associated with an increased risk of cardiovascular disease, including heart attack, stroke, and peripheral vascular disease.

Infections

Diabetes, particularly when poorly controlled, can increase the susceptibility to certain infections and may affect the body's ability to recover from illness.

Diabetes Treatment and Management

Diabetes management is individualized according to the type of diabetes, blood glucose levels, age, other medical conditions, and treatment goals.

Healthy eating and appropriate nutrition
Regular physical activity as medically appropriate
Weight management when appropriate
Blood glucose monitoring
Oral diabetes medicines when prescribed
Insulin when indicated
Regular medical follow-up
Monitoring for diabetes-related complications

What Is Good Diabetes Control?

Diabetes control should be individualized rather than based on one single number. Your healthcare professional can establish appropriate glucose and HbA1c targets according to your age, health status, medications, and risk of hypoglycemia.

Maintaining blood glucose within the recommended target range
Following the prescribed treatment plan
Maintaining a healthy lifestyle
Regular monitoring of blood pressure and cholesterol
Regular eye and kidney assessments
Proper foot care
Recognizing symptoms of low or high blood glucose
Attending regular medical check-ups

Common Risk Factors for Diabetes Mellitus

Family history of diabetes
Overweight or obesity
Physical inactivity
Unhealthy dietary patterns
Increasing age
History of gestational diabetes
Some pancreatic diseases
Certain genetic and hormonal conditions

Homeopathy and Diabetes Mellitus

Some homeopathic practitioners use individualized homeopathic preparations in people who have diabetes. However, there is insufficient reliable scientific evidence that homeopathic medicines can replace insulin, prescribed diabetes medicines, dietary management, or other evidence-based diabetes care.

People with diabetes should not stop insulin or prescribed medicines or change their treatment without discussing it with their treating healthcare professional.

Homeopathic Medicines Traditionally Discussed

Traditional homeopathic literature discusses preparations such as Phosphoric acid, Uranium nitrate, Helonias, and Syzygium in relation to diabetes. These traditional claims should not be interpreted as established evidence that these medicines treat or control diabetes.
