From the Guidelines
When taking a history for hyperglycemia, it is crucial to focus on symptoms, duration, risk factors, and current management to identify the cause, assess severity, and guide appropriate management decisions. This approach is supported by the most recent guidelines on the classification and diagnosis of diabetes, which emphasize the importance of considering both classic symptoms of hyperglycemia and the patient's individual risk factors and circumstances 1.
Key Components of History Taking
- Classic symptoms of hyperglycemia such as polyuria, polydipsia, polyphagia, weight loss, fatigue, blurred vision, recurrent infections, and slow-healing wounds should be inquired about, along with their onset and progression.
- A thorough family history of diabetes, personal medical history including cardiovascular disease, hypertension, dyslipidemia, and gestational diabetes, is essential for understanding the patient's risk profile.
- Current medications, especially those known to affect glucose levels like steroids, thiazide diuretics, atypical antipsychotics, and beta-blockers, should be documented.
- For patients with known diabetes, assessing their current management, including medication adherence, blood glucose monitoring patterns, typical readings, and any recent changes in treatment, is vital.
- Lifestyle factors such as diet, exercise habits, alcohol consumption, and smoking status, as well as psychosocial factors that might impact diabetes management (e.g., stress, depression, financial constraints, limited health literacy), should be explored.
- Documenting any previous diabetes education and the patient's understanding of the condition helps in tailoring the management plan to the patient's needs and circumstances.
Recent Guidelines and Recommendations
The 2023 standards of care in diabetes emphasize the importance of early detection and management of diabetes to prevent long-term complications 1. Given the increased risk of macrovascular and microvascular complications even in undiagnosed individuals with diabetes, a comprehensive history taking approach is critical. This includes considering the risk of developing type 2 diabetes, which increases with age, obesity, lack of physical activity, and in certain racial/ethnic subgroups, as well as in individuals with prior gestational diabetes mellitus or polycystic ovary syndrome.
Application in Clinical Practice
By following this comprehensive approach to history taking for hyperglycemia, healthcare providers can make informed decisions about the diagnosis, treatment, and management of diabetes, ultimately improving patient outcomes in terms of morbidity, mortality, and quality of life. The most recent evidence supports the notion that early intervention and personalized management can lead to better control of diabetes and its complications 1.
From the Research
Hyperglycaemia History Taking
When taking a history of hyperglycaemia, several factors should be considered:
- The patient's medical history, including any previous diagnoses of diabetes or other metabolic disorders 2
- The patient's current symptoms, such as increased thirst or urination, and any changes in vision or energy levels
- The patient's medication history, including any medications that may be contributing to hyperglycaemia, such as glucocorticoids 2
- The patient's lifestyle habits, including diet and physical activity level
Assessment of Hyperglycaemia
Assessment of hyperglycaemia involves:
- Measuring the patient's blood glucose levels, either through a fingerstick test or a laboratory test 3
- Evaluating the patient's HbA1c levels to determine their average blood glucose control over time 3
- Assessing the patient's risk factors for hyperglycaemia, such as family history, obesity, or physical inactivity
Management of Hyperglycaemia
Management of hyperglycaemia involves:
- Lifestyle modifications, such as diet and exercise, to help control blood glucose levels 4
- Medications, such as metformin or sulfonylureas, to help lower blood glucose levels 5, 6
- Monitoring of blood glucose levels and adjustment of treatment as needed to achieve optimal control 3
- Consideration of the patient's individual needs and preferences when selecting a treatment plan 4
Treatment Options
Treatment options for hyperglycaemia include:
- Metformin, which is often the first-line treatment for type 2 diabetes 5
- Sulfonylureas, which can be used in combination with metformin for patients who require additional glucose control 5, 6
- Insulin therapy, which may be necessary for patients with severe hyperglycaemia or those who are unable to achieve control with oral medications 2, 6
- Newer therapies, such as SGLT2 inhibitors and GLP-1 receptor agonists, which may be used in combination with other medications to achieve optimal control 3
