  Those suffering from diabetes or hypoglycemia can greatly benefit from devices used to detect low blood sugar. People with these types of conditions can be greatly injured or suffer fatality if they do not have a device to alert them that their blood sugar is low. Fortunately, there are a few different choices patients have when it comes to detecting their low blood sugar.
  
  

Blood Glucose Meter

• Blood glucose meters have been around for quite some time and are used regularly by hypoglycemic and diabetics alike to check the level of glucose in the blood. Many of these blood glucose meters are used by pricking the finger with a specialized tool and then dropping a bit of blood onto a strip, which is then inserted into the meter. Within seconds, the blood glucose meter gives out a reading that can tell you how low your blood sugar is currently. Blood glucose meters can be purchased from medical supply stores as well as pharmacies.
  
  

Helpful Companion

• A helpful companion is a specially trained dog that can reliably detect dangerous blood sugar level drops in diabetics, according to Piedmont Healthcare. Dogs already have a keen sense of smell and are used in a variety of other helpful jobs such as assisting the blind and deaf. Dogs for Diabetics is one of two sources in the United States that pairs diabetics with specially trained dogs. Before being paired up with one of these helpful companions, diabetics must first check with their doctor and then attend classes to learn how to use and care for the animal properly.
  
  

Hypoglycemia Symptoms Alarm

• A Hypoglycemia Symptoms Alarm (also known as a Night Sweat Alarm) is a specialized device that can awaken patients with hypoglycemia. The alarm detects low blood sugar and works by vibrating and making a loud audible noise to awaken those with hypoglycemia. The alarm is triggered when the unit senses a decrease in skin temperature or a presence of perspiration, which are two symptoms of hypoglycemia. The alarm looks similar to a wrist watch and can be worn on the wrist or ankle. The device can be easily purchased through retailers such as Amazon.
