Diabetes Mellitus: Type 2 and Gestational01:22

Diabetes Mellitus: Type 2 and Gestational

4.8K
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...

Carbohydrate Metabolism01:36

Carbohydrate Metabolism

10.4K
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...

Type 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.

Diabetes: Symptoms, Diagnosis, and Complications

2.5K
For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Type I Diabetes II: Pathophysiology

42
Type 1 diabetes mellitus arises from an immune-mediated destruction of pancreatic β-cells, resulting in an absolute deficiency of insulin. This process develops in genetically susceptible individuals when autoimmunity, environmental exposures, and immunologic dysregulation converge to trigger a targeted attack on the insulin-producing cells of the pancreas. The β-cells are located within the islets of Langerhans and are essential for regulating blood glucose by facilitating cellular...

Type I Diabetes III: Clinical Manifestations

14
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...

Area of Science:

  • Gerontology
  • Endocrinology
  • Sports Medicine

Background:

  • Type 2 diabetes mellitus (T2DM) prevalence increases with age, influenced by factors like obesity and sedentary lifestyles.
  • Elderly individuals with T2DM face unique challenges, including comorbidities, polypharmacy, frailty, and geriatric syndromes.

Purpose of the Study:

  • To emphasize the efficacy and safety of physical activity in managing T2DM among the elderly.
  • To provide guidance on exercise prescription for older adults with diabetes, considering their specific needs.

Main Methods:

  • Review of current evidence on physical activity interventions for elderly patients with T2DM.
  • Analysis of exercise modalities (aerobic, resistance, balance) and their impact on glycemic control and functional status.
  • Consideration of safety precautions and individual patient factors.

Main Results:

  • Physical activity is as effective as in younger populations for T2DM management in the elderly.
  • Moderate- to high-intensity exercises are safe and beneficial for glycemic control.
  • Combined aerobic and resistance training is the optimal approach, with specific frequencies recommended.

Conclusions:

  • Exercise prescription for elderly T2DM patients must account for contraindications, medications, comorbidities, and potential complications like hypoglycemia and orthostatic hypotension.
  • Personalized exercise plans enhance glycemic control, independence, self-esteem, and quality of life in older adults with diabetes.
