How is diabetes caused by obesity?

Insulin all used up: The pancreas gland makes insulin, which is required because Insulin makes blood sugar go into cells (blood sugar is the fuel for cells). A person gets obese by overeating, which puts lots of sugar into his blood each day. In the early years of obesity, he overworks his pancreas by demanding lots of Insulin from the gland. His pancreas "burns out" after a few years, and can't make Insulin anymore.

Fat is not just fat: Excess fat is not just a storage tissue, it is metabolically active, it produces inflammatory chemicals, this affects how Insulin is used in the body, Insulin becomes less effective at doing its job. The pancreas can eventually burn out, but usally the disease process has been going on years before this. People with a family history of diabetes are highest risk.
Dr. Pouya Shafipour

Insulin resistance: Type 2 diabetes is the Insulin resistance type of diabetes meaning blood sugar levels go up since the body cells have developed resistance to Insulin levels which cause the sugar to get into the cells. So blood sugar levels remain high. High abdominal fat and obesity are directly linked to development of diabetes type because abdominal fat is a major contributor to Insulin resistance.

A 30-year-old member asked:

Is it diabetes that causes obesity or obesity that cause diabetes or both?

Some of both: Type 2 diabetes is highly genetic, but if you were to keep your weight down, you may never get it, or perhaps only late in life. So obesity contributes to diabetes. Many medications that treat diabetes tend to make you gain weight (eg. Insulin, sulfonylureas, actos) and if you are frequently hypoglycemic, you will tend to eat more. So treatment of diabetes can contribute to obesity.

We know that obesity can be a cause of diabetes, but can diabetes actually cause obesity?

Depends: If you stay on a fixed dose of Insulin and try to eat more so you don't get low blood sugars, then yes, you can end up gaining some weight. Impt to distinguish the fact that this does not mean Insulin causes obesity (only if excessive Insulin results in overeating) patients on Insulin should have the dose adjusted to match healthy food intake, not the other way around.

Too many calories: Obesity is the result of intake (food) exceeding output(exercise). There are a few medical conditions that can cause obesity, such as untreated hypothyroidism, and prader willy syndrome. Some medications can also cause weight gain.

Obstructive Sleep Apnea, Metabolic Syndrome, and Hypothyroidism will lead to increases in weight. Others such as stress or menopause can change hormonal balance and lead to weight gain. Of course caloric balance is important as well. A Board Certified Obesity Specialist can help find a cause and medical or surgical solution solution.
