Because excess glucose in the blood can oxidize (damage) capillaries and other tissue, the body has safeguards to remove it.

The kidneys begin filtering out glucose over about 180 mg/dL (10 mmol/L) and excreting it with the urine, leading to loss of glucose.

Why was glucose excreted in urine?

glucose is excreted in urine in diabetes when the blood sugar level is beyond normal and insulin is not enough or not doing the job of transporting sugar to its target organ. The main reason is that because the kidneys cannot absorb all of the excess glucose in the body. This excess glucose spills into the urine, accompanied by water and electrolytes ions necessary for the cells to regulate the electric charge and flow of water molecules across the cell membrane. Hence this causes frequent urination to get rid of the additional water drawn into the urine and excessive thirst to trigger replacement of lost water.


What does a glucose monitor measure?

A glucose monitor measures the quantity of the simple sugar, glucose, in the subject's blood. This is important because persons with diabetes have lost some of their body's natural ability to control this nutrient.


is frequent urination a diabetic symptom?

With uncontrolled diabetes mellitus, glucose concentration in the blood is high (hyperglycemia) and reabsorption of glucose by the kidneys will be incomplete. Therefore, some glucose will stay in the urine. The presence of glucose increases osmotic pressure of the urine and as a result, the kidney does not retain the water for the body's use, but releases it and in doing so increases urine production.


Why does polydipsia occur with diabetes mellitus?

First reason for polyphagia is the intracellular starvation. As in diabetes either there is absence or the resistance to insulin action so glucose cannot move into the cells and thus cells are starved of glucose. Second reason can be the "Glucostat theory of feeding regulation". According to this theory arteriovenous difference of glucose in the hypothalamic satiety and feeding centers regulate the feeding response. If the difference is high due to the reason that glucose is more utilized by satiety center, the satiety center is activated. And if the difference is low then feeding center is activated. In diabetes due to insulin resistance or absence of insulin, glucose cannot move into the satiety center thus the arteriovenous difference remains low and the feeding center is chronically active. Thus polyphagia occurs.


Is glucose found in urine?

If your body doesn't take the glucose from the blood into the cells by using insulin, the glucose will be lost in the urine. Since you need glucose for your cells to survive, you need the insulin. If no insulin is produced or too little is, you are a diabetic and have to take some form of artificial insulin.


Why urine doesn't normally contain glucose?

Glucose is too valuable to be lost in the urine, so it is selectively reabsorbed by active transport in the nephrons. There should be no glucose whatsoever in urine. Any trace of it is a possible sign of diabetes.


Why is the lost bond in a form of chain?

The liver will bring the sugar/glucose back into the blood


What is dibeties?

It is of two typesDiabetes mellitusDiabetes mellitus is a common disease in the United States. It is estimated that over 16 million Americans are already caught with diabetes, and 5.4 million diabetics are not aware of the existing disease. Diabetes prevalence has increased steadily in the last half of this century and will continue rising among U.S. population. It is believed to be one of the main criterions for deaths in United States, every year. This diabetes information hub projects on the necessary steps and precautions to control and eradicate diabetes, completely.Diabetes is a metabolic disorder where in human body does not produce or properly uses insulin, a hormone that is required to convert sugar, starches, and other food into energy. Diabetes mellitus is characterized by constant high levels of blood glucose (sugar). Human body has to maintain the blood glucose level at a very narrow range, which is done with insulin and glucagon. The function of glucagon is causing the liver to release glucose from its cells into the blood, for the production of energy.There are three main types of diabetes:Type 1 diabetesType 2 diabetesGestational diabetesType 1 and Type 2 diabetes impede a person's carefree life. When breakdown of glucose is stopped completely, body uses fat and protein for producing the energy. Due to this mechanism symptoms like polydipsia, polyuria, polyphegia, and excessive weightloss can be observed in a diabetic. Desired blood sugar of human body should be between 70 mg/dl -110 mg/dl at fasting state. If blood sugar is less than 70 mg/dl, it is termed as hypoglycemia and if more than 110 mg /dl, it's hyperglycemia.Diabetes is the primary reason for adult blindness, end-stage renal disease (ESRD), gangrene and amputations. Overweight, lack of exercise, family history and stress increase the likelihood of diabetes. When blood sugar level is constantly high it leads to kidney failure, cardiovascular problems and neuropathy. Patients with diabetes are 4 times more likely to have coronary heart disease and stroke. In addition, Gestational diabetes is more dangerous for pregnant women and their fetus.Though, Diabetes mellitus is not completely curable but, it is controllable to a great extent. So, you need to have thorough diabetes information to manage this it successfully. The control of diabetes mostly depends on the patient and it is his/her responsibility to take care of their diet, exercise and medication. Advances in diabetes research have led to better ways of controlling diabetes and treating its complications. Hence they include:-New improved Insulin and its therapy, (external and implantable insulin pumps) have advanced well to manage elevated blood sugars without any allergic reactions.Oral hypoglycemic drug, controls diabetes type 2.New improved blood glucose monitor (new device for self blood glucose monitoring), and hemoglobin A1c laboratory test to measure blood glucose control during previous 3 months.Effective availability of the treatments for affected body organs due to diabetes.Better ways to manage mother and its fetus health during the gestational diabetes phase.Diabetes insipidusDiabetes insipidus (DI) is a rare disease that causes frequent urination. The large volume of urine is diluted, mostly water. To make up for lost water, a person with DI may feel the need to drink large amounts and is likely to urinate frequently, even at night, which can disrupt sleep and, on occasion, cause bedwetting. Because of the excretion of abnormally large volumes of dilute urine, people with DI may quickly become dehydrated if they do not drink enough water. Children with DI may be irritable or listless and may have fever, vomiting, or diarrhea. Milder forms of DI can be managed by drinking enough water, usually between 2 and 2.5 liters a day. DI severe enough to endanger a person's health is rare.


Cause of diabetes?

The causes of type 2 diabetes are as follows: old age not being active being fat bad diet But the most important of the causes is not producing enough insulin.


Why do doctor keep a patient on glucose drip after operation why?

Glucose is essentially sugar water. After an operation, glucose gives your body energy to a) replace lost blood b) keep you hydrated c) give your body energy it needs to heal.


Which renal structure transport glucose?

The proximal convoluted tubule in the kidney is responsible for reabsorbing glucose from the filtrate back into the bloodstream. This ensures that glucose is not lost in the urine and helps maintain normal blood sugar levels.


What is the normal glucose range in urine?

There should be no glucose in urine - it is too valuable to be lost from the body, so it is reabsorbed in the kidneys. Any traces of sugars in urine could be a sign of diabetes, and it would be wise to see your GP for further advice and tests.
