Summary
Excessive daytime sleepiness (EDS) is common in type 2 diabetes and linked to depression. Further research into antidepressant therapy for EDS is recommended.
Area of Science:
- Endocrinology
- Sleep Medicine
- Psychiatry
Background:
- Type 2 diabetes is associated with various health complications.
- Excessive daytime sleepiness (EDS) is a common complaint, but its prevalence and associations in type 2 diabetes require further investigation.
Purpose of the Study:
- To investigate the prevalence of excessive daytime sleepiness (EDS) in patients with type 2 diabetes.
- To explore the relationship between EDS and other sleep disorders, depressive symptoms, and comorbidity severity in this population.
Main Methods:
- A cohort of 110 patients with type 2 diabetes were assessed using validated questionnaires for EDS (Epworth Sleepiness Scale), sleep quality (Pittsburgh Sleep Quality Index), depression (Beck Depression Inventory), Restless Legs Syndrome (RLS), and risk of obstructive sleep apnea (OSA).
- Comorbidity severity was evaluated using the Charlson Comorbidity Index.
- Diabetic patients were compared to a control group of individuals with arterial hypertension but without diabetes.
Main Results:
- Diabetic patients exhibited higher rates of EDS, depressive symptoms, and comorbidity severity compared to hypertensive controls.
- Among diabetic patients, high prevalence of poor sleep quality (53.3%), risk of OSA (40.9%), and RLS (14.5%) were observed.
- EDS (55.5%) was significantly associated with depressive symptoms (44.5%), an association that persisted after adjusting for covariates (OR = 2.27).
Conclusions:
- Sleep abnormalities, including EDS, are frequent in type 2 diabetes.
- EDS is independently associated with depressive symptoms in this patient group.
- Clinical trials investigating the efficacy of antidepressant therapy for managing EDS in type 2 diabetes are warranted.

01:25Type II Diabetes Mellitus III: Clinical Manifestations and Diagnosis
Type 2 diabetes mellitus develops gradually and is often asymptomatic in early stages.Clinical ManifestationsWhen symptoms appear, they include fatigue, blurred vision, pruritus, delayed wound healing, and recurrent infections, particularly candidal infections. Peripheral neuropathy may present as numbness or tingling in the extremities. Classic hyperglycemia symptoms—polyuria, polydipsia, and polyphagia—are less common. Most patients are overweight and frequently have associated hypertension...
01:26Type II Diabetes I: Introduction
Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by insulin resistance, in which target tissues such as the liver, muscle, and adipose tissue respond poorly to insulin. It is also associated with inadequate compensatory insulin secretion, where pancreatic β-cells fail to produce sufficient insulin. Together, these abnormalities lead to persistent hyperglycemia.EtiologyT2DM develops through a complex interaction of genetic predisposition and environmental or...
01:24Type II Diabetes II: Pathophysiology
PathophysiologyType 2 diabetes mellitus (T2DM ) is a chronic metabolic disorder characterized by insulin resistance and progressive pancreatic β-cell dysfunction, leading to impaired glucose homeostasis. It results from interactions among genetic predisposition, environmental factors, and metabolic stressors, such as overnutrition and a sedentary lifestyle.Insulin Resistance and Glucose DysregulationEarly T2DM involves insulin resistance in skeletal muscle, adipose tissue, and the liver.
01:19Type I Diabetes III: Clinical Manifestations
Type 1 diabetes mellitus typically presents with rapid-onset symptoms due to the body’s inability to utilize glucose in the absence of insulin. Since insulin is required for glucose uptake into cells, its deficiency leads to hyperglycemia and cellular energy deprivation, resulting in characteristic clinical features.Polyuria and PolydipsiaOne of the earliest, most prominent symptoms is polyuria (excessive urination). When blood glucose concentrations rise above the renal threshold, the kidneys...
01:36Carbohydrate Metabolism
Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in the...

01:22Diabetes Mellitus: Type 2 and Gestational
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...
