Diabetes Mellitus (DM) is a prevalent, chronic metabolic condition characterized by the body’s impaired ability to process carbohydrates, fats, and proteins due to ineffective insulin utilization. This dysfunction leads to elevated blood glucose levels, posing significant health risks if not properly managed. Effective nursing care for individuals with diabetes hinges on accurate and timely nursing diagnoses, which guide interventions and improve patient outcomes.
In this article, we will explore various nursing diagnoses relevant to diabetes management, providing examples and insights to enhance your understanding and practice.
Types of Diabetes Mellitus
Understanding the different types of diabetes is crucial for formulating appropriate nursing diagnoses and care plans. Diabetes mellitus is broadly classified into:
Type 1 Diabetes: Characterized by an autoimmune reaction that destroys insulin-producing beta cells in the pancreas. Genetic predisposition and viral infections are considered potential contributing factors.
Type 2 Diabetes: The most common form, developing gradually over time. It results from the body’s resistance to insulin, leading to ineffective glucose utilization despite insulin production.
Gestational Diabetes: Occurs during pregnancy in individuals without a prior diabetes diagnosis. While typically resolving after childbirth, it elevates the risk of developing type 2 diabetes later in life.
Prediabetes: A precursor to type 2 diabetes, marked by blood glucose levels higher than normal but not yet meeting the criteria for type 2 diabetes. A fasting blood glucose level between 100-125 mg/dL indicates prediabetes.
Hypoglycemia and Hyperglycemia: Understanding Blood Glucose Imbalances
Managing diabetes effectively requires understanding and addressing both hypoglycemia (low blood glucose) and hyperglycemia (high blood glucose), as these conditions necessitate different nursing interventions and can result in distinct nursing diagnoses.
Hypoglycemia
Hypoglycemia is defined as abnormally low blood glucose levels, typically below 70 mg/dL. It demands immediate intervention to prevent progression to a medical emergency.
Causes of Hypoglycemia
Several factors can contribute to hypoglycemia in diabetic patients, including:
- Excessive insulin dosage
- Insufficient carbohydrate intake
- Improper timing of insulin administration relative to meals
- Increased physical activity without adequate glucose intake adjustment
- Alcohol consumption
- Environmental factors like hot and humid weather
- Hormonal fluctuations during puberty or menstruation
Hyperglycemia
Hyperglycemia signifies elevated blood glucose levels due to insufficient insulin availability in the bloodstream. A fasting blood glucose level exceeding 125 mg/dL or a postprandial (1-2 hours after eating) level above 180 mg/dL indicates hyperglycemia.
Causes of Hyperglycemia
Hyperglycemia can arise from a range of factors, such as:
- Dietary indiscretions, particularly high carbohydrate intake
- Reduced physical activity
- Infections or illnesses
- Psychological stress
- Steroid medication use
- Incorrect administration or dosage of diabetes medications (insulin or oral agents)
Nursing Assessment in Diabetes Mellitus
A comprehensive nursing assessment is the cornerstone of effective diabetes care. It involves gathering subjective and objective data encompassing the patient’s physical, psychosocial, emotional, and diagnostic status.
Review of Health History
1. General Symptom Assessment:
Recognizing the signs and symptoms of both hypoglycemia and hyperglycemia is crucial.
Hypoglycemia Symptoms:
- Heart palpitations
- Tremors or shaking
- Excessive sweating (diaphoresis)
- Nervousness or anxiety
- Confusion
- Dizziness
- Intense hunger
Hyperglycemia Symptoms:
- Frequent urination (polyuria)
- Excessive thirst (polydipsia)
- Increased hunger (polyphagia)
- Blurred vision
- Burning, tingling, or numbness in the extremities
- Fatigue
- Headaches
- Balanitis (penile inflammation) in men
Women with gestational diabetes may be asymptomatic, or exhibit hyperglycemia-like symptoms:
- Increased urination
- Increased hunger
- Increased thirst
- Blurred vision
- Nausea and vomiting
2. Diabetes Duration and Treatment History:
Inquire about the duration of the patient’s diabetes diagnosis and current or past treatments. The length of time living with diabetes and the effectiveness of glucose control are directly linked to the risk of long-term complications.
3. Age at Diagnosis:
Note the patient’s age at diabetes diagnosis. Type 1 diabetes can manifest at any age but is more common in childhood and adolescence. Type 2 diabetes is more prevalent in adults, typically over 40 years of age.
4. Risk Factor Investigation:
Assess both non-modifiable and modifiable risk factors for diabetes.
Non-Modifiable Risk Factors:
- Family History: A family history of diabetes significantly increases risk. Specific genetic mutations are associated with conditions like maturity-onset diabetes of the young (MODY) and neonatal diabetes.
- Race/Ethnicity: Certain racial and ethnic groups, including Black, Hispanic, American Indian, and Asian Americans, have a higher predisposition to type 2 diabetes.
- Age: Advancing age increases the risk of prediabetes and type 2 diabetes.
- Autoimmune Diseases: Autoimmune conditions can trigger the immune system to attack pancreatic insulin-producing cells, leading to latent autoimmune diabetes in adults (LADA) and type 1 DM.
- Hormonal Imbalances: Hormonal disruptions can impair the pancreas’ ability to produce sufficient insulin, contributing to insulin resistance and gestational or type 2 diabetes.
Modifiable Risk Factors:
- Obesity and Unhealthy Diet: Diets high in fat, calories, and cholesterol, coupled with obesity, significantly elevate diabetes risk. Overweight or obese individuals are more likely to develop prediabetes, type 2 diabetes, and gestational diabetes.
- Smoking: Smoking increases the risk of type 2 diabetes by 30-40% compared to non-smokers. Smokers with diabetes also experience greater challenges in managing their condition with insulin.
- Excessive Alcohol Consumption: Chronic heavy alcohol use can reduce insulin sensitivity, increasing type 2 diabetes risk.
- Sedentary Lifestyle: Lack of physical activity promotes insulin resistance, increasing the risk of prediabetes and type 2 diabetes.
- Chronic Conditions: Conditions like hypertension and hyperlipidemia increase the risk of diabetes complications and type 2 diabetes, respectively.
5. Yeast Infection History:
Inquire about recurrent yeast infections. Elevated glucose levels create a favorable environment for yeast proliferation. Excess glucose in the blood can lead to glycosuria (sugar in urine), promoting yeast overgrowth.
6. Diabetes-Related Complications Assessment:
Assess for existing complications associated with diabetes, which can arise from poorly managed or untreated diabetes (type 1 and 2):
- Cardiovascular Disease: Hyperglycemia damages blood vessels and nerves affecting the heart, increasing risks of hypertension, hyperlipidemia, coronary artery disease, angina, myocardial infarction, and cerebrovascular accidents.
- Neuropathy: Nerve damage due to hyperglycemia can cause tingling, numbness, burning pain, poor balance, reduced sensation, and increase risk of wounds and amputation, particularly in the extremities.
- Renal Disease (Nephropathy): Diabetes can impair small blood vessels in the kidneys, leading to kidney damage, potentially progressing to permanent failure requiring dialysis or transplant.
- Retinopathy: Damage to retinal blood vessels can cause diabetic retinopathy, increasing the risk of glaucoma and cataracts, potentially leading to blindness.
- Foot Damage: Neuropathy and poor circulation contribute to foot damage, increasing risk of slow-healing ulcers and infections.
- Depression: The complexity of diabetes management can contribute to depression, which can further complicate blood glucose control due to associated stress.
7. Blood Glucose Monitoring Records Review:
Request to review the patient’s blood glucose monitoring records from home devices to identify patterns of hyper- and hypoglycemia.
Physical Assessment
Patients with well-managed diabetes may not exhibit overt physical symptoms.
1. Blood Pressure and Respiratory Rate Monitoring: Hypertension is common in diabetic patients. Orthostatic hypotension can occur due to autonomic neuropathy. Kussmaul respirations (deep, rapid breathing) may indicate diabetic ketoacidosis (DKA).
2. Lower Extremity Pulse Palpation: Assess dorsalis pedis and posterior tibial pulses to evaluate for vascular compromise, a common complication of diabetes.
3. Foot Assessment: Perform a thorough foot assessment, especially for patients with sensory neuropathy or existing foot ulcers. Use the Semmes Weinstein monofilament test to assess sensory neuropathy, along with reflex and vibration perception testing.
4. Weight Assessment: Note any significant weight changes. Weight loss can occur in type 1 diabetes due to glucose loss and dehydration. Weight gain is common in type 2 diabetes and can exacerbate glucose control issues.
Diagnostic Procedures
1. Blood Glucose Testing: Blood glucose levels are central to diabetes diagnosis.
Diagnostic Criteria:
- Type 1 DM:
- Fasting glucose ≥ 126 mg/dL
- Random glucose ≥ 200 mg/dL
- HbA1c ≥ 6.5%
- Type 2 DM:
- Fasting glucose levels and HbA1c testing are used for diagnosis.
- Borderline/Prediabetes:
- Glucose tolerance test (OGTT) assesses fasting glucose and serum glucose response to an oral glucose load.
- Prediabetes:
- Fasting blood sugar (FBS) 100-125 mg/dL
- 2-hour post-OGTT glucose 140-200 mg/dL
- Gestational Diabetes:
- Screening during 24-28 weeks gestation:
- 1-hour glucose challenge test
- 3-hour glucose challenge test (if initial test > 140 mg/dL) for confirmation.
- Screening during 24-28 weeks gestation:
2. Other Lab Results Monitoring:
- Urine Albumin: Detects early diabetic nephropathy, particularly in type 1 DM.
- Serum Lipids: Monitored due to increased cardiovascular risk in diabetic patients.
- Thyroid Levels: Annual thyroid testing is advised due to higher hypothyroidism prevalence in diabetic individuals.

4. Maintain Optimal Glucose Levels: Aim for HbA1c below 7% and blood glucose between 90 and 130 mg/dL to minimize long-term complications.
5. Type 1 and Type 2 DM Treatment Differences: Explain treatment variations for type 1 (insulin injections, pumps, monitoring, carb counting, transplants) and type 2 DM (lifestyle modifications, monitoring, oral medications, insulin).
6. Insulin Administration Education: Provide thorough instruction and return demonstration on proper insulin administration techniques, including drawing up insulin and using insulin pens.
7. Insulin Pump Assistance: Explain and assist with wearable insulin pumps, including their function and bolus adjustments for meals. Closed-loop insulin delivery systems (artificial pancreas) can also be discussed as advanced options.
8. Oral Diabetes Medication Education: Educate patients with type 2, prediabetes, or gestational diabetes about oral medications, their mechanisms, and different classes (alpha-glucosidase inhibitors, biguanides, bile acid sequestrants, dopamine-2 agonists, DPP-4 inhibitors, meglitinides, SGLT2 inhibitors, sulfonylureas, thiazolidinediones).
9. Pancreas Transplant Discussion: For select type 1 DM patients with poor glucose control or needing a kidney transplant, discuss pancreas transplantation as an option, including risks and the need for immunosuppression.
10. Meal Planning Guidance: Educate patients on diabetic diets, emphasizing reduced carbohydrates, processed foods, and sugars. Instruct on increasing fruits, vegetables, lean proteins, and whole grains. Involve patients in meal plan creation.
11. Nutritionist/Dietitian Referral: Refer patients to a registered nutritionist or dietitian for personalized meal planning and carbohydrate counting education, especially for type 1 diabetes or insulin users.
12. Promote Physical Activity: Encourage at least 150 minutes of moderate weekly exercise, after obtaining healthcare provider clearance. Explain how exercise lowers blood glucose and improves insulin sensitivity.
13. Weight Management: For overweight/obese type 2 DM or prediabetes patients, emphasize that even a 7% weight loss can improve glucose control.
14. Gestational Diabetes Management: Manage gestational diabetes with blood glucose monitoring, oral agents or insulin if needed, and close monitoring during labor due to potential neonatal hypoglycemia.
15. Diabetes Prevention Education: For prediabetes, emphasize healthy lifestyle changes (weight management, balanced diet, exercise) to prevent progression to type 2 diabetes. Metformin, statins, or antihypertensives may be considered in some high-risk individuals.
16. Diabetologist/Endocrinologist Referral: Refer patients to endocrinologists or diabetologists for specialized diabetes management.
Prevent Complications: Nursing Interventions
1. Medical Alert ID Recommendation: Advise patients to wear a medical alert ID to provide critical medical information in emergencies like DKA or hypoglycemia.
2. Ophthalmologist Referral: Recommend annual eye exams with an ophthalmologist to screen for retinopathy, cataracts, and glaucoma.
3. Vaccination Promotion: Encourage recommended vaccinations, as diabetes can weaken the immune system.
4. Foot Care and Exams Education: Instruct on daily foot inspections, proper washing and drying, avoiding lotion between toes, and regular podiatry visits, especially for nail care or neuropathy.
5. Blood Pressure and Cholesterol Management: Promote healthy lifestyle and medication adherence to manage blood pressure and cholesterol levels and prevent vascular complications.
6. Oral Hygiene Education: Emphasize twice-daily brushing and flossing, and routine dental exams to prevent gum infections.
7. Smoking Cessation Encouragement: Strongly advise smoking cessation to reduce the risk of diabetic complications, especially cardiovascular disease.
8. Moderate Alcohol Consumption Guidance: Advise moderation (≤ 2 drinks/day for men, ≤ 1 drink/day for women, with food) due to alcohol’s effects on blood glucose.
9. Stress Management Techniques: Teach stress-coping strategies to mitigate stress hormones’ impact on insulin function.
10. Diabetes Nurse Educator Coordination: Refer patients to diabetes nurse educators for comprehensive self-management education and support.
11. DSMES Program Referral: Recommend Diabetes Self-Management Education and Support (DSMES) programs to improve self-efficacy, healthy behaviors, and reduce complications and hospitalizations.
