Even as things stand now, there are a lot of people left out in the cold. A 2016 study, for instance, found that only 41,000 people with diabetes annually get bariatric surgery in the US—fewer than 5 percent of the total new cases diagnosed every year. And the longer someone has diabetes, studies have suggested, the less likely they are to go into remission if they eventually get surgery. Getting those numbers up will not only require changing the minds of insurers, but public opinion, too.
In 1991, the National Institutes of Health issued a consensus statement, cautiously recommending surgery as a treatment for people living with morbid obesity, meaning they have a body mass index, or BMI, over 40. For people who have health complications connected to obesity, such as type 2 diabetes, the limit goes down to a BMI of 35. Relying on these guidelines, insurance companies and public payers like Medicaid and Medicare typically only cover surgery for people living with diabetes who fall into that category.
Some cases of diabetes are caused by the body's tissue receptors not responding to insulin (even when insulin levels are normal, which is what separates it from type 2 diabetes); this form is very uncommon. Genetic mutations (autosomal or mitochondrial) can lead to defects in beta cell function. Abnormal insulin action may also have been genetically determined in some cases. Any disease that causes extensive damage to the pancreas may lead to diabetes (for example, chronic pancreatitis and cystic fibrosis). Diseases associated with excessive secretion of insulin-antagonistic hormones can cause diabetes (which is typically resolved once the hormone excess is removed). Many drugs impair insulin secretion and some toxins damage pancreatic beta cells. The ICD-10 (1992) diagnostic entity, malnutrition-related diabetes mellitus (MRDM or MMDM, ICD-10 code E12), was deprecated by the World Health Organization (WHO) when the current taxonomy was introduced in 1999.
Glucagon is a hormone that causes the release of glucose from the liver (for example, it promotes gluconeogenesis). Glucagon can be lifesaving and every patient with diabetes who has a history of hypoglycemia (particularly those on insulin) should have a glucagon kit. Families and friends of those with diabetes need to be taught how to administer glucagon, since obviously the patients will not be able to do it themselves in an emergency situation. Another lifesaving device that should be mentioned is very simple; a medic-alert bracelet should be worn by all patients with diabetes.
Insulin is a type of hormone made up of 45 amino acids, and it is important for signaling to the body’s cells to pick up excess sugar from the bloodstream. Normally, whenever you decide to drown yourself in a Big Gulp from 7-Eleven, the sugars in the soda will be absorbed through your stomach directly into your bloodstream. Insulin is pumped out by the pancreas, which acts as a signal that gives the thumbs up to your muscles and fat cells to throw a sweet rager with the soda you just dumped into your body. Everyone has a good time – until the party ends.
In gastroesophageal reflux disease (GERD), sometimes called heartburn, stomach acid and partially undigested food move backward through the esophagus, escaping from the stomach and through the esophageal sphincter that normally prevents such backsliding. This can occur as a symptom of gastroparesis, says Hiroshi Mashimo, MD, PhD, a gastroenterologist at Harvard Medical School. “If the stomach doesn’t empty, it’s likely to reflux up,” he says. GERD may also result from diabetes-related nerve damage affecting the esophageal sphincter, Mashimo adds. One caution: Some diseases, such as a yeast infection in the esophagus, can masquerade as GERD, so don’t brush off symptoms. We can’t treat the gastroparesis or esophageal sphincter problems that contribute to GERD, but antacids and other medications can help to reduce or neutralize stomach acids (see “PPIs the Right Way,” below).

Tyler played college basketball at Utah State from 2007-2011, and had the opportunity to play in three NCAA tournaments. His coaches and trainers always had Gatorade or candy on hand in case his blood glucose dropped during a game. Tyler tested his blood glucose right before training, and during halftime breaks. He says working out and playing basketball has helped him to better control his T1D.
While there is a strong genetic component to developing this form of diabetes, there are other risk factors - the most significant of which is obesity. There is a direct relationship between the degree of obesity and the risk of developing type 2 diabetes, and this holds true in children as well as adults. It is estimated that the chance to develop diabetes doubles for every 20% increase over desirable body weight.
When the glucose concentration in the blood remains high over time, the kidneys will reach a threshold of reabsorption, and glucose will be excreted in the urine (glycosuria). This increases the osmotic pressure of the urine and inhibits reabsorption of water by the kidney, resulting in increased urine production (polyuria) and increased fluid loss. Lost blood volume will be replaced osmotically from water held in body cells and other body compartments, causing dehydration and increased thirst (polydipsia).

Triglycerides are a common form of fat that we digest. Triglycerides are the main ingredient in animal fats and vegetable oils. Elevated levels of triglycerides are a risk factor for heart disease, heart attack, stroke, fatty liver disease, and pancreatitis. Elevated levels of triglycerides are also associated with diseases like diabetes, kidney disease, and medications (for example, diuretics, birth control pills, and beta blockers). Dietary changes, and medication if necessary can help lower triglyceride blood levels.
If the amount of insulin available is insufficient, or if cells respond poorly to the effects of insulin (insulin insensitivity or insulin resistance), or if the insulin itself is defective, then glucose will not be absorbed properly by the body cells that require it, and it will not be stored appropriately in the liver and muscles. The net effect is persistently high levels of blood glucose, poor protein synthesis, and other metabolic derangements, such as acidosis.
After rising to MySpace fame in the mid-aughts, the singer-songwriter Kaila Yu amassed a following of nearly half a million fans on Facebook and 70,000 on Twitter and Instagram. Like all “influencers”—people who leverage a social-media following to influence others—Yu now makes her living monetizing her audience with branded content, promoting products and events through sponsored posts.
In normal persons the hormone insulin, which is made by the beta cells of the pancreas, regulates how much glucose is in the blood. When there is excess glucose in the blood, insulin stimulates cells to absorb enough glucose from the blood for the energy that they need. Insulin also stimulates the liver to absorb and store any glucose that is excess in blood. Insulin release is triggered after a meal when there is rise in blood glucose. When blood glucose levels fall, during exercise for example, insulin levels fall too.
Hypoglycemia means abnormally low blood sugar (glucose). In patients with diabetes, the most common cause of low blood sugar is excessive use of insulin or other glucose-lowering medications, to lower the blood sugar level in diabetic patients in the presence of a delayed or absent meal. When low blood sugar levels occur because of too much insulin, it is called an insulin reaction. Sometimes, low blood sugar can be the result of an insufficient caloric intake or sudden excessive physical exertion.
Some research, however, suggests a more drastic dietary change. A 2017 literature review concluded that “whole-foods, plant-based diet—legumes, whole grains, fruits, vegetables, and nuts, with limited or no intake of refined foods and animal products—are highly beneficial for preventing and treating type 2 diabetes.” A 2018 study found that overweight people who switched to a vegan diet for 16 weeks showed improvements in insulin sensitivity compared to a control group.
The classic oral glucose tolerance test measures blood glucose levels five times over a period of three hours. Some physicians simply get a baseline blood sample followed by a sample two hours after drinking the glucose solution. In a person without diabetes, the glucose levels rise and then fall quickly. In someone with diabetes, glucose levels rise higher than normal and fail to come back down as fast.
A 2018 study suggested that three types should be abandoned as too simplistic. It classified diabetes into five subgroups, with what is typically described as type 1 and autoimmune late-onset diabetes categorized as one group, whereas type 2 encompasses four categories. This is hoped to improve diabetes treatment by tailoring it more specifically to the subgroups.
Also known as smart insulin, Professor John Fossey at the University of Birmingham is developing this type of insulin delivery system which is designed to circulate in the body, inactive, until blood glucose levels start to rise. As they do, the insulin goes to work to bring these levels back down, ensuring perfect glucose control throughout any given day.
Diabetes is a disease that occurs when your blood glucose, also called blood sugar, is too high. Blood glucose is your main source of energy and comes from the food you eat. Insulin, a hormone made by the pancreas, helps glucose from food get into your cells to be used for energy. Sometimes your body doesn’t make enough—or any—insulin or doesn’t use insulin well. Glucose then stays in your blood and doesn’t reach your cells.
