Diabetes: Symptoms, Diagnosis, and Complications

Diabetes: Symptoms, Diagnosis, and Complications

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 based on...

Hyperglycemia

Hyperglycemia

Hyperglycemia is an abnormally high blood glucose level. It is diagnosed by fasting glucose ≥126 mg/dL, 2-hour oral glucose tolerance test (or OGTT) ≥200 mg/dL, random glucose ≥200 mg/dL with symptoms, or HbA1c ≥6.5%. However, HbA1c results may be unreliable in certain conditions, such as anemia or hemoglobinopathies, and the diagnosis should be confirmed unless classic symptoms are present. Postprandial hyperglycemia is typically considered significant when glucose levels exceed 180 mg/dL two...

Diabetes Mellitus: Type 2 and Gestational

Diabetes 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...

Metabolic States of the Body: Fasting and Starvation

Metabolic States of the Body: Fasting and Starvation

During the initial hours of fasting, the body uses up its glycogen stores as an energy source. Once these glycogen reserves are depleted, the body begins breaking down stored triglycerides and structural proteins. During this stage, glycerol becomes a key substrate for gluconeogenesis, while free fatty acids undergo beta-oxidation to provide energy for tissues, such as skeletal muscle. In the fasting state, the body spares protein breakdown as much as possible to conserve muscle and structural...

Type II Diabetes Mellitus III: Clinical Manifestations and Diagnosis

Type 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...

Type I Diabetes III: Clinical Manifestations

Type 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...

Summary

Muslims with diabetes often fast during Ramadan, despite religious exemptions. This fasting impacts health, requiring careful management and medication adjustments for safe observance.

Area of Science:

Endocrinology
Metabolic Disorders
Religious Studies

Background:

Muslims observe fasting from food and liquids during daylight hours in Ramadan.
Despite exemptions for the sick, many individuals with diabetes choose to fast.
Fasting during Ramadan significantly alters daily routines, including diet, activity, and sleep.

Purpose of the Study:

To highlight the health implications of fasting during Ramadan for people with diabetes.
To emphasize the need for awareness among patients, families, and healthcare providers regarding Ramadan fasting and diabetes.
To inform risk stratification and management strategies for diabetic patients observing Ramadan.

Main Methods:

Review of the physiological and metabolic effects of Ramadan fasting on diabetic patients.

Analysis of the impact of altered dietary habits, physical activity, and sleep patterns.

Consideration of religious perspectives on fasting for individuals with diabetes.

Main Results:

Ramadan fasting affects glycaemic control, lipid profiles, body weight, and dietary intake.
Pre-Ramadan assessment and education are crucial for risk management.
Adjustments to insulin and oral hypoglycaemic agents, particularly sulphonylureas, are often necessary.

Conclusions:

Patients with diabetes considering fasting during Ramadan require comprehensive pre-fasting evaluation and education.
Healthcare providers must be prepared to modify diabetes management plans, including medication timing and dosage.
Balancing religious observance with health management is essential for diabetic individuals during Ramadan.
