Medical Conditions A - Z

Smart Self Management Tech

Smart Tech

These days, monitoring blood glucose levels has become more painless, convenient and accurate. As medical innovation advances, more tech devices are available to help diabetic patients gain better control of their health condition. Dr Nitish Mishra, Specialist in Endocrinology & Consultant, Raffles Diabetes & Endocrine Centre, shares the pros and cons of two main types of such devices.

Glucose Monitors

There are more improved glucose monitors that can be worn on the body to monitor your blood sugar levels without getting your finger pricked. They can be worn on such as back of the arm to measure blood glucose levels at close intervals throughout the day without any interaction. User can receive real time data via a supporting app on the mobile phone.

PROS: This type of device is reasonably accurate and revolutionary for type 1 diabetic
                patients. It reduces the apprehension and anxiety levels for patients who need to
                monitor their glucose levels more frequently.

CONS: It is unsuitable for the majority of type 2 diabetic patients as they do not need to
                monitor their glucose levels on a frequent and regular basis.

Insulin Pumps

Injecting insulin multiple times daily can be deterring and inconvenient to most diabetic patients. Insulin pumps allow users to attach a cannula sturdily under the skin once and be connected to a cartridge of insulin that is delivered to the user for two to three days before the need to change the cannula for hygiene purpose.

PROS: Insulin pumps are excellent for those type 1 diabetic patients who have busy and
               unpredictable schedules. 
Users can conveniently adjust the dosage more 
               accurately based on continuous blood glucose monitoring to 
tweak their basal

               Such devices allow users to influence their blood glucose values on an hourly     
               basis as compared to traditional 
injections that are usually of an interval of four
               to eight hours. They can significantly reduce hypoglycemic 

Cons: Users need to operate the pump and calculate meal time doses based on their
              carbohydrate content and blood 
glucose levels.

              It may be obvious that they are diabetic if they wish to be discreet about it.

              They may feel uncomfortable having something attached.
