Limitations of Current BGM System

Blood glucose monitoring meters or other systems have been one of the most important trailblazing discoveries in the management of different types of diabetes. This is since the discovery of insulin changed the clinical mode of controlling the disease in the 1920s. It is a great step towards management of diabetes that the BGM equipment are omnipresent. But half a century back, it was almost impossible to monitor glucose levels in the blood of diabetes patients.

Early development in the field of blood glucose monitoring devices began in 1963 when a color changing paper strip called Dextrostix® was invented by Ernie Adams. A few years later in 1970, Anton H Clemens invented the first blood glucose monitoring meter called Armes Reflectance Meter (ARM).


Slowly, the world grew comfortable with the device and now home-based self-monitoring by patients has become common. BGM machines are used by a wide range of patient groups for controlling and monitoring the chronic disorder. Most medical associations recognize the importance of measuring and monitoring the glucose levels in hypoglycemic and hyperglycemic patients on a continuous basis and also recognizes that any deviation from normal should be quickly discovered, analyzed and corroborated through technical and clinical methods so that the necessary treatment can be started immediately. For this, they recommend diabetes patients to use BGM systems on a daily basis for their disease management and mitigation.

However, even though the existing BGM Systems found today are a very important management tool, there are great limitations:

  • Another accuracy challenge is that a CGM sometimes gives a faulty reading for biological reasons, such as a small blood clot forming around the sensor.
  • The continuous invasive systems found today have the disadvantage that the sensors are not accurate enough and calibrations with standard glucose sensor is necessary at least a couple of times per day.
  • The financial burden on healthcare on society.
  • A huge problem is that this very often leads to low compliance to check the blood glucose level. Inadequate insulin management could very easily lead to Hypo – or Hyperglycemia.
  • The main glucose monitoring methods are not continuous, invasive and the costs for measuring strips are high.
  • Acetaminophen (paracetamol) and other medications can also throw off CGM Readings.
  • Skin infections may occur.
  • The major other drawback is the price level on the sensor.
