Glucose goes from the body to the blood. When carbohydrates are consumed, they are catabolised to mono saccharides (glucose, fructose, galactose are mono saccharides). These mono saccharides are absorbed into the body from the small intestine and circulated to the cells with the help of blood and lymph.
Digestion of gulcose (or rather say carbohydrates) starts from the mouth itself,where our saliva converts it into glucose and simple sugars,about 30% of carbohydrates are coverted here,after reaching the small intestine,glucose (converted from carbohydrates with the help of some enzymes) is absorbed by small finger like projections present on the inner wall of small intestine called villi. These villi are attached to small blood capillaries from the outer wall of small intestine and glucose (or any other nutrient) gets absorbed in the blood. The blood then provides this glucose to each and every living cell of our body.
Glucose is the type of sugar present in your blood that is checked to detect glucose-related diseases (e.g. Diabetes mellitus).
Since glucose is the simplest building unit of storage carbohydrates, it is supplied to the body by foods containing carbohydrates -mostly plant food.
Glucose is the main source of energy utilized by the body. Muscles have
their own stored glucose in the form of glycogen, to use it independently from glucose content of the diet.
Liver, also stores glucose as glycogen, through which it regulates the blood sugar whenever there is a shortage of glucose supply by the diet. Liver can make glycogen from materials other than glucose like amino acids.
Blood is where the brain stores its glucose needs, consequently the blood glucose levels should not be allowed to be maintained under a certain level, and the whole body is responsible for that, firstly the liver through hydrolysing its glycogen (glycogenolysis), and secondly- in extreme cases- the muscle affords its protein in the form of amino acids for the liver to synthesize glucose through a process called
gluconeogenesis.
Control of blood sugar is performed through many hormones like insulin, glucagon, growth hormone, thyroid hormone, corticosteroids, sex hormones, epinephrine, and nor-epinephrine.
Insulin is the only hormone that deals with glucose in supplied by foods directly, as it produced by the effect of glucose in the blood on pancreas, while other hormones contribute to control blood glucose in an intricate process affected by age, sex, type of food, and genetic and health condition of an individual.
Normally, blood glucose level increases slightly after eating, and this increase induces secretion of more insulin to control blood sugar not to get too high. High blood glucose over time has many damaging effects on blood vessels, kidney, nerves, and eyes.
Hyperglycemia means the blood sugar is above normal values, and hypoglycemia means that the blood sugar is below normal. Diabetes mellitus is a disease where the body can not handle glucose supplied by food raising blood glucose. It is caused by failure of the body cells to respond to insulin, or failure of the pancreas to secrete insulin.
Blood glucose tests are used to diagnose raised blood glucose:
- Fasting blood sugar measures blood glucose after you have not eaten for at least 8 hours. Values should be less than 5.5 mmol/L
- Postprandial blood sugar measures blood glucose exactly 2 hours after you eat a meal. Values should be less than 7.8 mmol/L
- Random blood sugar measures blood glucose regardless of when you last ate. Several random measurements may be taken throughout the day. Random testing is useful because glucose levels in healthy people do not vary widely throughout the day. Blood glucose levels that vary widely may indicate a problem. This test is also called a casual blood glucose test. Values should be less than 7 mmol/L
- Oral glucose tolerance test is used to diagnose prediabetes and diabetes. An oral glucose tolerance test is a series of blood glucose measurements taken after you drink a sweet liquid that contains glucose. This test is commonly used to diagnose diabetes that occurs during pregnancy (gestational diabetes). It is not commonly used to diagnose diabetes in a person who is not pregnant.
Glucose moves into the filtrate in the glomerulus and is then reabsorbed as it travels down the nephron.

Nothing happens to the glucose. It should have been stored in the kidney, but it didn't, therefore, you have an excess amount glucose in your blood. Hence, the insulin shots.
diabetes
It is reabsorbed into the blood through blood capillaries surroundings the tubule
It gets absorbed into the blood stream via Lumen and a Glucose/Na+ symporter, Na+/K+ atpase and glucose 2 uniporter, but essentially is absorbed into the blood stream.
Renal threshold is what happens when there is an overabundance of glucose in the body, the blood glucose levels will then get above 170mg/100ml (normal is 70mg/100ml).
elevated glucose value
After the glucose is absorbed into the blood it is taken to the liver and is either stored or distributed to cells throughout the body for energy. To provide enough energy for the body the liver regulates blood glucose levels. Example: excess glucose is converted to glycogen in the liver and is stored. Likewise, if blood sugar levels fall it is reconverted back to glucose. Not sure about amino acids :P
The kidneys may excrete glucose in the urine. very high blood glucose levels can damage almost every system and cell in the body, including the coronary artery. In other terms, Diabetes can occur.
