Wrist or ankle worn blood sugar alarm

A blood sugar alarm that is worn on the wrist or ankle is used to warn of hypoglycaemia, otherwise known as low blood sugar in diabetics. Low blood sugar alarms are at their most useful at night although they can be worn throughout the day.

These devices look very much like regular watches, however they use sensors to detect key indicators of hypoglycaemia and sound or vibrate a warning if a problem is identified.

The sensors used in these alarms work by identifying sweat levels and body temperature and they can provide and early (and usually) accurate warning that can then be verified by a blood test. Appropriate remedial action can then be taken before a serious problem arises.

Wrist or ankle worn blood sugar alarms are adjustable (in a similar way to the watch design that they mimic) and they are comfortable and unobtrusive to wear.

Further features

Many of these alarms have a memory function that allows a data record of warnings to be stored and this can aid in determining future insulin levels.

These devices run off a battery and have a moulded plastic case in which the sensors are housed. It is this plastic case that needs to be maintained in direct contact with the skin at all times. This contact can be around the wrist or the ankle.

Some of these devices also include a blood pressure monitor and read-out, however wrist worn blood pressure monitors do not always provide the most accurate of readings (see blood pressure monitor) page.
