Introduction and History of Diabetes Mellitus
Abstract
Diabetes is the seventh leading cause of death in the United States. Its two primary forms are: type 1, in which no insulin is secreted by the pancreas, and type 2, in which the body can no longer normally produce or utilize insulin. Diabetes has been studied since the 5th century BC, though it was named in 1674, based on the sweetness of urine in diabetics. Both type 1 and 2 diabetes originate from autoimmune destruction of the pancreatic beta cells. There are also other less common forms, including gestational diabetes, which develop during pregnancy. The three primary signs of diabetes are: polydipsia, polyphagia, and polyuria.
Diabetes may cause many different conditions. These include diabetic foot and ketoacidosis, eye damage, heart disease, kidney and nerve damage, nonketotic hyperosmolarity, poor wound healing, and infections of various body tissues. Over time, excellent methods of diagnosis of diabetes have been developed. Unfortunately, prevalence of the disease has greatly increased in the United States, as well as in other countries. In the early 20th century, treatment for diabetes became more effective when insulin was first isolated. As a result, the lives of many diabetic patients are longer and more fulfilling than in previous years.

Diabetes is very common in the United States, with more than 30 million Americans having the disease. This makes up 9.4% of the countryâs population. Diabetes is the seventh leading cause of death in the United States. The condition known as diabetes mellitus is characterized by high fasting blood glucose. This is tested by taking a blood sample following an overnight period in which the patient has not consumed any types of food.
There are two primary forms of diabetes, which are known as diabetes type 1 and diabetes type 2. In type 1, the beta (Ă) cells of the pancreas can no longer secrete insulin. As a result, blood glucose levels become elevated to a condition called hyperglycemia. Almost 75% of type 1 diabetes cases are diagnosed in people under the age of 18 years. Type 2 diabetes occurs when the beta cells of the pancreas can no longer allow glucose to enter in order to produce energy. Studies have shown that the risks of developing type 2 diabetes are higher in people who have a family history, are inactive, and are overweight or obese.
Diabetes has become much more widely understood since the early 1980s, though the disease has existed for much longer. The perception is that a ânewerâ disease surrounds the components of the modern diet and lifestyle. Diabetes mellitus is related to less-than-adequate physical activity, increased caloric intake, and the resulting factor of obesity being much more common than in previous times. This situation occurs all over the world. Written records about diabetes have existed for thousands of years, in many different countries.
History
The first recorded record of diabetes mellitus comes from India, during the 5th century BC. Descriptions of the disease included the terms emaciation, excessive urination with a sweet odor, and thirst. In ancient Egypt (approximately 460 and 1550 BC), the disease was described as including excessive urination, but there was no description of a âsweet odor.â In China (475â221 BC and AD 229) diabetes was described similarly to the Indian description, and it is believed that the people who wrote the symptoms down were describing patients with type 2 diabetes. They linked it with the following risk factors: large quantities of calories, eating of cereal, rice, and sweets, and as being more common in rich peopleâmeaning that they could better afford these kinds of foods.
The actual term âdiabetesâ is credited to Demetrius of Apameia (approximately the 1st or 2nd century BC). The term is derived from the Greek language, originally meaning âto siphonâ or âto empty.â The first clinical description of diabetes came from Aretaeus of Cappadocia (approximately AD 81â138). In his book called Therapeutics of Chronic Diseases, he even described a âcureâ for the disease.
Both Aretaeus and Galen of Pergamum (approximately AD 129â200) believed that the kidneys were the source of urine, and that diabetes was a rare form of kidney disease. Galen (Fig. 1.1) experimented on dogs to substantiate his findings. Both of them did not use any term describing the âsweetnessâ of urine. It is possible that they were actually describing diabetes insipidus, which is caused by lack of antidiuretic hormone or antidiuretic hormone, and not diabetes mellitus.
For the next 500 years, Greek physicians were very approving of Galenâs work concerning diabetes. They added new medical writings focused mostly on treatments for the condition, which included bloodletting, medicinal herbs, and even various types of wine. The first diagnostic test for diagnosing diabetes was by actually tasting urine. The sweet taste was written about by the Asians, Egyptians, and Indians. In AD 229, Chang Chung-Ching commented that the urine was so sweet that dogs liked it. In the 5th century, medical texts from the Hindu culture described the urine as being like sugarcane or sweet honey. In AD 630, Theodore Protospatharios recommended that diagnosis of diabetes should include examination of th...
