What is Urine Glucose - PP, Urine Sugar - PP?
The Glucose Postprandial Test is performed to measure glucose levels in the urine to screen for Prediabetes and Diabetes Types 1 and 2. The test is done after a period of 2 hours from the start of the last meal. The word ‘Postprandial’ means after eating a meal.
Why is Urine Glucose - PP, Urine Sugar - PP done?
The glucose postprandial is done:
- If you have signs or symptoms of diabetes like excessive thirst, excessive hunger, excessive urine frequency, and weight loss
- To monitor glucose levels in diabetics for assessing kidney damage
- To assess the effect of treatment in diabetics
What does Urine Glucose - PP, Urine Sugar - PP Measure?
The Glucose Postprandial Test measures glucose levels in the urine after a period of 2 hours from the start of the last meal.
Glucose is a simple sugar or monosaccharide which is the main source of energy for all the cells of the body. It is important to know that glucose is the only energy source for the nervous system. Carbohydrates consumed in the diet are broken down into their simplest form called glucose, which is absorbed by the intestines and transported by the blood to various organs. It is subsequently utilized by cells of these organs to produce energy wherever necessary. The quantity in excess is stored either as glycogen in the liver for short-term storage or in fat tissues as triglycerides for long-term storage. The uptake, utilization, and storage of glucose after it is absorbed in the intestines is facilitated by the hormone insulin secreted by the pancreas. Insulin guides the transport of glucose to the organs requiring it (e.g., heart, brain, working muscles, etc.). Insulin also directs the storage of excess glucose. The action of insulin reduces sugar levels in the blood.
After every meal, sugar levels increase in the blood, and insulin is secreted as a response to reduce the sugar levels until it becomes normal. If glucose levels fall too low in the blood, another pancreatic hormone called glucagon is released. Glucagon directs the liver to convert stored glycogen into glucose and release it into the blood. The insulin and glucagon hormones create a feedback mechanism to keep blood glucose levels within the normal range. An imbalance in their activity can cause high or low blood sugar levels in the blood.
The kidney filters the blood to form urine. Normally, urine has little or no glucose. In case of very high glucose levels, glycosuria or a high level of glucose in the urine is noted. The test results help to monitor insulin therapy in patients with diabetes mellitus.
Interpreting Urine Glucose - PP, Urine Sugar - PP results
The reference range for glucose post-prandial, urine lies in between 0 - 15 mg/dL.
The reference range may vary from lab to lab*
- The presence of glucose in urine is usually suggestive of diabetes
- The absence of glucose in urine usually means no diabetes
What are the risk factors for Diabetes?
Diabetes can be caused by various reasons. The most common risk factors for diabetes include being obese or overweight with low physical activity, having a blood relative diagnosed with Diabetes, or having been diagnosed with hypertension. Other reasons which can cause diabetes could be low High-Density Lipoproteins or high triglyceride levels, being diagnosed with Polycystic Ovarian Syndrome, or having been diagnosed with gestational diabetes and cardiovascular diseases.
What is Hyperglycemia and what are its symptoms?
Hyperglycemia refers to a condition where the blood glucose level is above the normal range. This condition may indicate prediabetes or diabetes and may cause significant health problems. Symptoms of Hyperglycemia include increased thirst, frequent urge to urinate, weakness, tiredness (fatigue), blurring of vision and, slow healing of a wound.
