The World Health Organization (WHO) Global Report on Diabetes 2016 says that the number of diabetics around the world rose four-fold from 108 million in 1980 to 422 million by the year 2014. Diabetes and its complications rank high in the list of risk factors, and causes of death throughout the world.
Diabetes, also called hyperglycemia, is a chronic condition in which the body's blood sugar levels rise too much. This happens when the pancreas can't make enough insulin or the body stops reacting to the insulin it makes. Insulin helps the body use glucose for various functions, thus keeps the levels of glucose under control.
Diabetes can be of two types:
- Type-1 diabetes (insulin-dependent): In this type of diabetes, the beta cells of the islets of Langerhans get damaged and thus the pancreas cannot make insulin.
- Type-2 diabetes (non-insulin-dependent): In this type of diabetes, the body becomes insulin resistant.
But in some cases, the glucose levels in diabetics suddenly drop to less than 70mg/dL. This condition is called hypoglycemia which is mostly seen in a diabetic who has skipped a meal, has indulged in vigorous exercise or taken too much insulin. This is a life-threatening condition and requires immediate treatment or else the person can fall into a diabetic coma.
Whenever there is a hypoglycemic emergency, the affected person starts getting pale, cold and clammy, sweaty with increased heart rate and pulse rate. The person may be seen trembling, confused and might lose consciousness. Immediate first aid can be given to the person by providing them with glucose-rich foods and beverages such as juices, bread, biscuits and honey.
