John Rollo M.D. (d. December 23, 1809) was a Scottish military surgeon, now known for his work on a diabetic diet. Rollo was the first to suggest a low-carbohydrate diet as a treatment for diabetes. [1]
He was born in Scotland, and received his medical education at Edinburgh. He became a surgeon in the Royal Artillery in 1776, and then served in the West Indies. In 1778 the University of St Andrews made him M.D. [2] He was stationed in St. Lucia in 1778–9 and in Barbados in 1781. [3] His associates included Colin Chisholm on Grenada. [4]
Rollo became surgeon-general of the Royal Artillery in 1794, and returned to the Royal Military Academy, Woolwich. [3] There he oversaw the construction of the enlarged Royal Artillery Hospital: the Royal Ordnance Hospital dated from about 1780, and the enlargement was completed in 1806 (the building later became the Connaught Barracks). [2] [5] From 1804 he was inspector of hospitals for the Ordnance. [2]
Rollo was frequently consulted about cases of diabetes, and in treatment had some success with the use of a nitrogenous diet. He died at Woolwich on 23 December 1809, and was buried at Plumstead in Greenwich. [3] [6]
In 1797, Rollo printed at Deptford Notes of a Diabetic Case, which described the improvement of an officer with diabetes who was placed on a meat diet. [3] He was the first to take Matthew Dobson's discovery of glycosuria in diabetes mellitus and apply it to managing metabolism. [7] By means of Dobson's testing procedure (for glucose in the urine) Rollo worked out a diet that had success for what is now called type 2 diabetes. [8] The addition of the term "mellitus", distinguishing the condition from diabetes insipidus, has been attributed to Rollo. [9]
Rollo's diet for diabetic patients consisted of "milk, lime water, bread and butter, blood pudding, meat, and rancid fat". [10] He has been described as "the first one to recommend a diet low in carbohydrates as a treatment for diabetes." [1]
Rollo collaborated with William Cruickshank, who was the chemistry assistant at Woolwich. In another edition of the work, An Account of Two Cases of the Diabetes Mellitus, published in 1798, other cases were added, and some of Cruikshank's research on urine and sugar in diabetics was included. [11] A further edition appeared in 1806. [3] John Latham supported Rollo's views on the treatment. [12] In 1824 the Encyclopædia Britannica in its article "Dietetics" commented that the diet was successful in repressing the condition of the patients' urine, but that the patients often found the high fat content intolerable. [13] This kind of dietary management continued to the 1920s, being more successful for adults, who might survive some years, than for young patients who typically had only some months of life on it. [14] Other collaborations of Rollo and Cruikshank related to treatments for syphilis involving acids, and published with the work on diabetes; [15] [16] proteinuria; and strontium. [17]
Rollo published Observations on the Diseases in the Army on St. Lucia, in 1781; and in 1785 Remarks on the Disease lately described by Dr. Hendy, on a form of elephantiasis known as "Barbados leg". In 1786 he published Observations on the Acute Dysentery. [3]
Rollo published in 1801 a Short Account of the Royal Artillery Hospital at Woolwich. He had kept a record of his cases in Barbados, and the Account included a similar table for the Ordnance hospital. [18] [19] In 1804 a Medical Report on Cases of Inoculation supported the views of Edward Jenner. [3]
Diabetic ketoacidosis (DKA) is a potentially life-threatening complication of diabetes mellitus. Signs and symptoms may include vomiting, abdominal pain, deep gasping breathing, increased urination, weakness, confusion and occasionally loss of consciousness. A person's breath may develop a specific "fruity" smell. The onset of symptoms is usually rapid. People without a previous diagnosis of diabetes may develop DKA as the first obvious symptom.
Type 2 diabetes (T2D), formerly known as adult-onset diabetes, is a form of diabetes mellitus that is characterized by high blood sugar, insulin resistance, and relative lack of insulin. Common symptoms include increased thirst, frequent urination, fatigue and unexplained weight loss. Other symptoms include increased hunger, having a sensation of pins and needles, and sores (wounds) that heal slowly. Symptoms often develop slowly. Long-term complications from high blood sugar include heart disease, stroke, diabetic retinopathy, which can result in blindness, kidney failure, and poor blood flow in the lower-limbs, which may lead to amputations. The sudden onset of hyperosmolar hyperglycemic state may occur; however, ketoacidosis is uncommon.
Polyuria is excessive or an abnormally large production or passage of urine. Increased production and passage of urine may also be termed as diuresis. Polyuria often appears in conjunction with polydipsia, though it is possible to have one without the other, and the latter may be a cause or an effect. Primary polydipsia may lead to polyuria. Polyuria is usually viewed as a symptom or sign of another disorder, but it can be classed as a disorder, at least when its underlying causes are not clear.
Diabetic nephropathy, also known as diabetic kidney disease, is the chronic loss of kidney function occurring in those with diabetes mellitus. Diabetic nephropathy is the leading causes of chronic kidney disease (CKD) and end-stage renal disease (ESRD) globally. The triad of protein leaking into the urine, rising blood pressure with hypertension and then falling renal function is common to many forms of CKD. Protein loss in the urine due to damage of the glomeruli may become massive, and cause a low serum albumin with resulting generalized body swelling (edema) so called nephrotic syndrome. Likewise, the estimated glomerular filtration rate (eGFR) may progressively fall from a normal of over 90 ml/min/1.73m2 to less than 15, at which point the patient is said to have end-stage renal disease. It usually is slowly progressive over years.
Feline diabetes mellitus is a chronic disease in cats whereby either insufficient insulin response or insulin resistance leads to persistently high blood glucose concentrations. Diabetes affects up to 1 in 230 cats, and may be becoming increasingly common. Diabetes is less common in cats than in dogs. The condition is treatable, and if treated properly the cat can experience a normal life expectancy. In cats with type 2 diabetes, prompt effective treatment may lead to diabetic remission, in which the cat no longer needs injected insulin. Untreated, the condition leads to increasingly weak legs in cats and eventually to malnutrition, ketoacidosis and/or dehydration, and death.
Diabetic hypoglycemia is a low blood glucose level occurring in a person with diabetes mellitus. It is one of the most common types of hypoglycemia seen in emergency departments and hospitals. According to the National Electronic Injury Surveillance System-All Injury Program (NEISS-AIP), and based on a sample examined between 2004 and 2005, an estimated 55,819 cases involved insulin, and severe hypoglycemia is likely the single most common event.
Ketonuria is a medical condition in which ketone bodies are present in the urine.
Elliott Proctor Joslin was the first medical doctor in the United States to specialize in diabetes and was the founder of the present-day Joslin Diabetes Center in Boston, Massachusetts.
A diabetic diet is a diet that is used by people with diabetes mellitus or high blood sugar to minimize symptoms and dangerous complications of long-term elevations in blood sugar.
Sir Thomas Lauder Brunton, 1st Baronet, was a British physician who is most-closely associated with the use of amyl nitrite to treat angina pectoris.
Apollinaire Bouchardat was a French pharmacist and hygienist born in L'Isle-sur-Serein.
Frederick Madison Allen was an American physician who is best remembered for his carbohydrate-restricted low-calorie diet for sufferers of diabetes mellitus. He was known for developing the "starvation diet" as a treatment.
Complications of diabetes are secondary diseases that are a result of elevated blood glucose levels that occur in diabetic patients. These complications can be divided into two types: acute and chronic. Acute complications are complications that develop rapidly and can be exemplified as diabetic ketoacidosis (DKA), hyperglycemic hyperosmolar state (HHS), lactic acidosis (LA), and hypoglycemia. Chronic complications develop over time and are generally classified in two categories: microvascular and macrovascular. Microvascular complications include neuropathy, nephropathy, and retinopathy; while cardiovascular disease, stroke, and peripheral vascular disease are included in the macrovascular complications.
Diabetes mellitus is a disease in which the beta cells of the endocrine pancreas either stop producing insulin or can no longer produce it in enough quantity for the body's needs. The disease can affect humans as well as animals such as dogs.
The condition known today as diabetes is thought to have been described in the Ebers Papyrus. Ayurvedic physicians first noted the sweet taste of diabetic urine, and called the condition madhumeha. The term diabetes traces back to Demetrius of Apamea. For a long time, the condition was described and treated in traditional Chinese medicine asxiāo kě. Physicians of the medieval Islamic world, including Avicenna, have also written on diabetes. Early accounts often referred to diabetes as a disease of the kidneys. In 1674, Thomas Willis suggested that diabetes may be a disease of the blood. Johann Peter Frank is credited with distinguishing diabetes mellitus and diabetes insipidus in 1794.
Matthew Dobson (1732–1784) was an English physician and experimental physiologist. He is now remembered for his work on diabetes.
Diabetes mellitus, often known simply as diabetes, is a group of common endocrine diseases characterized by sustained high blood sugar levels. Diabetes is due to either the pancreas not producing enough insulin, or the cells of the body becoming unresponsive to the hormone's effects. Classic symptoms include thirst, polyuria, weight loss, and blurred vision. If left untreated, the disease can lead to various health complications, including disorders of the cardiovascular system, eye, kidney, and nerves. Diabetes accounts for approximately 4.2 million deaths every year, with an estimated 1.5 million caused by either untreated or poorly treated diabetes.
Arnaldo Cantani, also known as Arnoldo Cantani, was an Italian physician and writer best known for his research on diabetes.
Arthur Scott Donkin was a British physician and writer known for his research on diabetes. Donkin proposed a skimmed milk treatment for Bright's disease and diabetes.
Russell Morse Wilder Sr. was an American physician, diabetologist, epileptologist, and medical researcher, known as one of the originators of the ketogenic diet as a therapy for both epilepsy and diabetes. He coined the term "ketogenic diet." He was also among the first American physicians to use insulin for patients with diabetes.
