Study Notes

Benefits of Early Diabetes Diagnosis

Early diagnosis of diabetes mellitus can prevent or delay the onset of serious complications like cardiovascular disease, kidney failure, and nerve damage.
Improved management strategies can be implemented sooner, leading to better long-term health outcomes and quality of life.

Diagnostic Tests for Diabetes Mellitus

Fasting Blood Glucose Test: Measures glucose levels after fasting for at least 8 hours.
Oral Glucose Tolerance Test (OGTT): Measures blood sugar levels before and after consuming a glucose-rich drink, assessing how well the body processes sugar.
Hemoglobin A1c Test: Indicates average blood glucose levels over the past 2-3 months, used for both diagnosis and monitoring of diabetes.

Consequences of Delaying Diabetes Diagnosis

Delayed diagnosis can lead to progressive complications that could have been avoided with early intervention, resulting in increased healthcare costs and decreased patient well-being.

Non-Contributing Factors to Importance of Glucose Testing

Personal lifestyle choices, like diet and exercise, do not diminish the necessity of glucose testing; rather, they are integrated into managing diabetes effectively.

True Statements about Glucose Tests in Management

Regular glucose testing is crucial for monitoring blood sugar levels and adjusting treatment plans, enabling patients to maintain target glucose ranges and reduce long-term complications.

Urine

Urine is a fluid excreted by mammals, including humans.
It is formed in the kidneys (renal glomeruli).
Urine undergoes chemical changes before it is excreted.
Healthy urine excretion is about 1.5 L per day.

Physical Properties of Urine

Normal urine volume is between 0.4-2.0 L/day.
Polyuria (excess urine) can indicate diabetes or chronic renal failure.
Oligouria (low urine) can indicate dehydration or acute renal failure.
Normal urine appearance is clear, colorless, and yellow with a urine-like odor.
Cloudy urine can indicate the presence of pus cells, bacteria, salt, or epithelial cells.
Orange urine can indicate dehydration or carotenoid ingestion.
Green-yellow urine can indicate jaundice.
Red urine can indicate blood, drugs, or other substances.
Dark brown-black urine can indicate methemoglobin, alkaptonuria, melanoma, or black water fever.
Smoky urine can indicate glomerulonephritis.
Fruity odor can indicate diabetic ketoacidosis.
Ammoniacal odor can indicate contaminated or long-standing exposed urine.
Mousy odor can indicate phenylketonuria.
Burnt sugar odor can indicate maple syrup urine disease.
Urine deposits can indicate crystals, salts, cells, or blood clots.
Normal urine pH is between 4.6-7.0.
Acidic urine can indicate ketosis, metabolic and respiratory acidosis, and excessive meat or fruit consumption.
Alkaline urine can indicate respiratory and metabolic alkalosis, urinary tract infection, or a vegetarian diet.

Chemical Properties of Urine

Normal protein levels in urine are less than 200 mg/day.
Proteinuria is the presence of excess protein in the urine.
Glomerular proteinuria indicates increased glomerular permeability due to conditions like glomerulonephritis.
Tubular proteinuria indicates decreased tubular reabsorption with normal glomerular permeability due to conditions like chronic nephritis.
Normal urine contains no glucose.
Glucosuria indicates the presence of glucose in the urine.
Glucosuria can be caused by uncontrolled diabetes, gestational diabetes, Fanconi’s syndrome, or diabetic ketoacidosis.
Normal urine contains no ketones.
Ketonuria indicates the presence of ketones in the urine.
Ketonuria can be caused by uncontrolled diabetes, starvation, prolonged vomiting, glycogen storage disease, or unbalanced diet.
Normal urine contains no nitrites.
Nitrites in urine indicate a urinary tract infection (UTI).
Normal urine contains no bilirubin.
Bilirubin in urine indicates hepatic and post-hepatic jaundice.
Normal urobilinogen levels are up to 1mg/dl.
High urobilinogen levels (above 2mg/dl) can indicate jaundice.
Normal urine contains no blood.
Hematuria indicates the presence of blood in the urine.
Hematuria can be caused by acute and chronic glomerulonephritis, trauma, cystitis, renal calculi, tumors, bleeding disorders, or hemophilia.
Hemoglobinuria indicates the presence of hemoglobin in the urine.
Hemoglobinuria can be caused by hemoglobinopathies, malaria, or transfusion reactions.

Proteins

Normally, less than 200 mg of protein is excreted in the urine daily.
Proteinuria is the condition of more than 200 mg of protein excreted daily.
Glomerular proteinuria is due to increased glomerular permeability, leading to the filtration of high molecular weight proteins (e.g. glomerulonephritis).
Tubular proteinuria is caused by decreased tubular reabsorption with normal glomerular permeability, leading to the excretion of low molecular weight proteins (e.g. chronic nephritis).

Nephrotic Syndrome

This syndrome is characterized by significant protein loss in urine, leading to hypoproteinemia.
Increased protein excretion in urine can be classified into two types:
- High molecular weight protein excretion: related to Glomerular proteinuria.
- Low molecular weight protein excretion: related to Tubular proteinuria.
