People with diabetes may need to take insulin injections to control their high blood glucose.
Homeostasis can be defined as an organism's tendency to maintain the equilibrium of different internal systems by using various biochemical and physical processes. Under normal circumstances, the body is able to balance the amount of glucose, or sugar, in the blood with the amount of glucose that the cells need for fuel.
The other side of the equation in glucose homeostasis involves glucagon — another hormone produced by the pancreas. In a healthy individual, these hormonal interactions and adjustments maintain a fairly constant and optimal blood glucose level. Insufficient insulin and insulin resistance are associated with diabetes mellitus and can cause severe hyperglycemia. Hypoglycemia, or low blood glucose, is typically considered less serious than hyperglycemia unless the hypoglycemia is present in a patient with diabetes. Even for people who do not have and are not at risk for diabetes, glucose levels in the blood can really effect energy levels and your general health.
I get that both types of diabetics have trouble maintaining homeostasis of blood glucose levels. Another consideration to picking the best blood sugar monitor for you is finding one that you find to be easy to use. Related to ease of use is how much blood is required for each test and some brands and models require less blood than others. Not long ago, the ability to check the level of glucose in human blood was limited to the medical laboratory, then the first bulky at home machines were invented and blood glucose monitoring entered a whole new era. Regardless of the advancements made in technology, one aspect of the monitors has remained unchanged since their inception, and that is the need for blood to be drawn into the monitor via test strip for the glucose level to be checked.
The newest trend in the quest for a better glucose monitor is the non invasive blood glucose monitor. While the technology is not yet advanced enough for the non invasive blood glucose monitor to replace the standard variety, new advancements are being made every day, and one day soon everyone may be able to monitor their glucose without paying for it in blood. This device was developed by three Biomedical Engineering students of SSN College of Engineering, Kalavakkam as final year project. The original device offers a “non-invasive assessment of hemoglobin oxygen saturation and pH in a region of skeletal muscle tissues beneath the oximeter sensor,” according to the company. Hacking the computers of an American company and stealing and erasing confidential information likely doesn't rise to the level of an “armed attack” against the United States. So they could look for (and attach to) cancerous cells, cancerous DNA, or monitor chemicals in the bloodstream, or a buildup of plaque that can cause cancer and heart attacks. A non-invasive way to monitor blood sugar could help millions of diabetics check their condition without drawing blood.
Provides information about handling type 2 diabetes, including monitoring glucose levels, increasing exercise, paying attention to nutrition, and reducing the long-term effects.


This volume presents the 5th European Conference of the International Federation for Medical and Biological Engineering, held in Budapest, September, 2011. The Israeli company OrSense has developed a new non-invasive technology for monitoring blood glucose levels for diabetes.
According to The Verge, the lens which was developed and unveiled by Google X in January, analyzes tear fluid in the eye using non-invasive sensors to measure a person's blood glucose levels constantly. Blood glucose monitors are used to measure the amount of glucose in blood, especially of patients with symptoms or a history of abnormally high or low blood glucose levels.

Examples of homeostasis in humans include the body's attempt to maintain a fairly constant and normal blood pressure, and its efforts to regulate internal body temperature. The hormone insulin, which the pancreas produces, facilitates the transport of glucose into the cells.
When something interrupts this glucose homeostasis, a person may experience blood glucose levels outside the normal range for a healthy person. In such cases, the hypoglycemia can mean an overdose of administered insulin or oral medication, which can lead to dangerously low blood glucose levels. If you stick to whole wheat and whole fruit (which does have a lot of sugar, but also have fiber to help you metabolize it more slowly), you'll be a lot better off! I probably understand Type 1 better; their bodies do not produce insulin, so they cannot metabolize glucose, so they develop sever hyperglycemia and will die if left untreated. But then why do they wind up *low* blood sugar? The handheld electronic items have evolved greatly and most are now compact and easy to use.
Some monitors can determine the level of glucose in the blood with a smaller amount of blood, which means a smaller prick to draw blood. Ever since the ability to check the level of glucose in the blood was first developed the technology and tools have been steadily improving, especially since the advent of the at home glucose monitor.
From those slow and bulky machines of yesterday the modern at home blood glucose monitor has evolved into a sleek and compact unit that fits easily in a pants or shirt pocket, can store more than two hundred memory entries with ease, and can read the glucose levels in a tiny drop of blood in fifteen second or less. This of course had cause untold amounts of discomfort to millions of people because each glucose checks must be accompanied my poking a hole in the skin with a needle.
These new inventions are worn like a wrist watch and sample the blood glucose level in interstitial fluid which is painlessly drawn through the sweat glands via a small electric charge. Princeton Professor Claire Gmachl is developing a technology to do just that, using a laser to measure blood sugar through the skin.
Topics discussed include: signal and image processing, ICT, clinical engineering and applications, biomechanics and fluid biomechanics, and biomaterials and tissue repair.
Another example of human homeostasis is glucose homeostasis, also known as blood glucose regulation or blood sugar regulation.
Too little available insulin in the bloodstream will reduce the amount of glucose that the cells are able to absorb.


Hyperglycemia, or high blood glucose, can occur when the pancreas produces insufficient insulin or when cells are resistant to insulin.
Often, individuals with diabetes will need to take insulin injections or oral medications to control their high blood glucose. Less serious cases can occur because of fasting, overexertion, or some metabolic condition.
If an insulin-dependent diabetic overshoots the insulin, and takes too much, his or her blood sugar levels will drop too low.
Some points to help differentiate each type of blood sugar monitor are cost, ease of use, the amount of blood required and enhanced computer-related features.
Also, the amount of time it takes for the blood sugar monitor to obtain an accurate reading varies greatly from model to model. These non invasive blood glucose monitors are designed to be worn for up to twelve hours at a time with a sample taken as often as every twenty minutes. The firm’s sensor uses Raman spectroscopy to non-invasively detect glucose in blood by shining light through the skin and detecting changes in the returning spectrum. Glucose homeostasis relies on the balance and interactions of two hormones — insulin and glucagon — to maintain a healthy blood glucose level.
This will raise the blood glucose level, which in turn stimulates the pancreas to release more insulin and allow more glucose absorption.
The hormone stimulates the liver to release glucose stored within its cells, thus raising blood glucose levels to a normal level.
Left untreated, diabetes mellitus and the associated hyperglycemia can damage the kidneys, eyes, and circulatory system. Taking a sugary drink will quickly bring blood sugar levels back up to normal and prevent more serious complications. Some can produce a reading within five seconds, which can be important for a diabetic person suffering from low blood sugar. Some monitors can only hold the previous 10 readings, while other, usually more expensive, models are capable of holding up to 500 readings.
Many of these blood glucose monitors are equipped with an alarm that alerts the wearer if their blood glucose getting either too high or too low. There has indeed been progress in the development of non-invasive continuous blood glucose monitors.
For more enhanced interaction, some monitors can be linked to a computer with specialized software. Users can download their test results, organize them and track them over a period of months or years.
