📄 2. Introduction
Diabetes Mellitus is a chronic metabolic disorder characterized by increased blood glucose level due to defect in insulin secretion, insulin action or both. Insulin is a hormone produced by beta cells of the pancreas. It helps glucose enter the body cells and provides energy. When insulin is insufficient or ineffective, glucose remains in the blood and causes hyperglycemia.
Diabetes Mellitus is a major public health problem worldwide. It affects people of all age groups but is more common among adults, obese persons, people with sedentary lifestyle and those having family history of diabetes. If diabetes is not controlled properly, it can lead to serious complications affecting the eyes, kidneys, nerves, heart, blood vessels and feet. Nurses play an important role in early detection, blood glucose monitoring, medication support, diet counselling, foot care education and prevention of complications.
📄 3. Definition
Diabetes Mellitus is a group of metabolic diseases characterized by chronic hyperglycemia resulting from defects in insulin secretion, insulin action or both.
📄 4. Anatomy and Physiology Related to Diabetes
The pancreas is a gland located behind the stomach. It has both exocrine and endocrine functions. The endocrine part of the pancreas contains islets of Langerhans. Beta cells of islets of Langerhans produce insulin. Insulin helps in the transport of glucose from blood into cells. It also helps in storage of glucose as glycogen in liver and muscles. In diabetes mellitus, insulin production is reduced or body cells become resistant to insulin, resulting in increased blood glucose level.
📄 5. Types of Diabetes Mellitus
- Type 1 Diabetes Mellitus: It occurs due to destruction of beta cells of pancreas, leading to absolute insulin deficiency. It is commonly seen in children and young adults.
- Type 2 Diabetes Mellitus: It occurs due to insulin resistance and relative insulin deficiency. It is the most common type and is commonly associated with obesity, sedentary lifestyle and family history.
- Gestational Diabetes Mellitus: Diabetes first detected during pregnancy is called gestational diabetes mellitus.
- Secondary Diabetes: It occurs due to other diseases, drugs or pancreatic disorders.
📄 6. Causes of Diabetes Mellitus
- Insulin deficiency
- Insulin resistance
- Genetic factors
- Autoimmune destruction of beta cells
- Obesity
- Sedentary lifestyle
- Unhealthy dietary habits
- Pancreatic disease
- Hormonal disorders
- Long-term use of certain drugs such as steroids
📄 7. Risk Factors
- Family history of diabetes
- Age above 40 years
- Overweight and obesity
- Lack of physical activity
- Unhealthy diet rich in sugar and fat
- Hypertension
- High cholesterol level
- History of gestational diabetes
- Polycystic ovarian syndrome
- Stress and sedentary lifestyle
📄 8. Pathophysiology
In Diabetes Mellitus, the body is unable to use glucose properly due to lack of insulin or resistance to insulin. In Type 1 diabetes, beta cells of the pancreas are destroyed and insulin production becomes very low or absent. In Type 2 diabetes, insulin is produced but body cells do not respond properly to insulin. This condition is called insulin resistance.
Due to decreased insulin action, glucose cannot enter the cells effectively. As a result, blood glucose level increases. The body cells do not get enough glucose for energy, so the body starts breaking down fats and proteins. Persistent hyperglycemia causes damage to blood vessels and nerves, leading to long-term complications such as retinopathy, nephropathy, neuropathy, cardiovascular disease and diabetic foot.
📄 9. Signs and Symptoms
- Polyuria: frequent urination
- Polydipsia: excessive thirst
- Polyphagia: excessive hunger
- Unexplained weight loss
- Fatigue and weakness
- Blurred vision
- Slow wound healing
- Recurrent infections
- Itching, especially genital itching
- Numbness or tingling sensation in hands and feet
- Dry mouth
- Dehydration in severe cases
📄 10. Diagnostic Evaluation
| Test | Diagnostic Value |
|---|---|
| Fasting Blood Glucose | 126 mg/dL or more |
| Random Blood Glucose | 200 mg/dL or more with symptoms |
| Oral Glucose Tolerance Test | 2-hour plasma glucose 200 mg/dL or more |
| HbA1c | 6.5% or more |
| Urine Sugar Test | May show glucose in urine |
| Urine Ketone Test | Useful in uncontrolled diabetes or Type 1 diabetes |
📄 11. Medical Management
- Maintain blood glucose level within normal range.
- Diet control and meal planning.
- Regular physical exercise.
- Oral antidiabetic drugs as prescribed.
- Insulin therapy if required.
- Regular blood glucose monitoring.
- Management of hypertension and cholesterol.
- Prevention and early treatment of complications.
- Regular follow-up with health care provider.
📄 12. Insulin Therapy
Insulin therapy is required in Type 1 diabetes and may also be required in Type 2 diabetes when blood glucose is not controlled by diet, exercise and oral medicines. Insulin should be administered as prescribed by the physician. The patient should be taught correct injection technique, insulin storage, rotation of injection sites and recognition of hypoglycemia.
📄 13. Oral Antidiabetic Drugs
Oral antidiabetic drugs are commonly used in Type 2 diabetes mellitus. These medicines help to reduce blood glucose level by increasing insulin secretion, improving insulin sensitivity or reducing glucose absorption. The patient should take medicines regularly as prescribed and should not stop medication without medical advice.
📄 14. Nursing Management
- Assess patient’s general condition and symptoms of hyperglycemia or hypoglycemia.
- Monitor blood glucose level as advised.
- Monitor vital signs and body weight.
- Assess dietary pattern and lifestyle habits.
- Administer insulin or oral antidiabetic drugs as prescribed.
- Observe for signs of hypoglycemia such as sweating, tremors, hunger, confusion and weakness.
- Educate patient regarding diet, exercise and medication compliance.
- Teach foot care and skin care.
- Encourage regular follow-up and laboratory investigations.
- Provide psychological support and counselling.
📄 15. Nursing Care Plan
| Nursing Diagnosis | Goal | Nursing Intervention | Rationale | Evaluation |
|---|---|---|---|---|
| Risk for unstable blood glucose level related to imbalance between insulin, diet and activity. | Patient will maintain blood glucose within target range. | Monitor blood glucose level and observe signs of hypo/hyperglycemia. | Regular monitoring helps early detection and management of abnormal glucose level. | Patient maintained better blood glucose control. |
| Deficient knowledge related to diabetes management. | Patient will understand diet, medicine, exercise and follow-up care. | Teach about disease process, medication, diet, exercise and warning signs. | Knowledge improves self-care and prevents complications. | Patient verbalized diabetes self-care measures. |
| Risk for infection related to high blood glucose level. | Patient will remain free from infection. | Teach personal hygiene, skin care, foot care and early reporting of wounds. | Hyperglycemia increases risk of infection and delayed wound healing. | No signs of infection were observed. |
| Risk for impaired skin integrity related to poor circulation and neuropathy. | Patient will maintain intact skin and healthy feet. | Inspect feet daily and advise proper footwear. | Foot care prevents injury, ulcer and diabetic foot complications. | Patient demonstrated foot care practices. |
📄 16. Diet Management in Diabetes
Diet management is an important part of diabetes control. The patient should take a balanced diet with controlled carbohydrate intake, adequate protein, healthy fats, fiber-rich foods and limited sugar. Meals should be taken at regular intervals to prevent sudden rise or fall in blood glucose level.
| Recommended Foods | Foods to Limit / Avoid |
|---|---|
| Whole grains, dal, pulses and vegetables | Sweets, sugar, jaggery and sugary drinks |
| Green leafy vegetables and salads | Deep fried foods and fast foods |
| Low-fat milk and curd | Refined flour products like maida items |
