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.
Replacing humans with computers could make patients better control their sugar levels and suffer less complications in the long term. The French company Cellnovo has already shown that just a partially automated system, where blood sugar levels can be monitored wirelessly but patients still select insulin amounts, can reduce the chances of reaching life-threatening low sugar levels up to 39%. The company is now working towards developing a fully automated artificial pancreas in collaboration with Imperial College, the Diabeloop consortium and the Horizon2020 program.
Diarrhea and constipation may also stem from diabetes-related gut movement issues. And the conditions may be related. “Diarrhea doesn’t mean fast motion; constipation doesn’t mean slow movement,” says Mashimo, happy to clear up a common misconception. “They can be two sides of the same coin.” Constipation, he says, is caused by slow movement of the bowels, which can cause a buildup of harmful bacteria in the colon that, in turn, triggers diarrhea.
Dr. May currently works as a fulltime endocrinologist and has been in private practice since 2004. He has a variety of interests, predominantly obesity and diabetes, but also sees patients with osteoporosis, thyroid disorders, men's health disorders, pituitary and adrenal disorders, polycystic ovaries, and disorders of growth. He is a leading member of several obesity and diabetes societies and runs a trial centre for new drugs.
"You only need 10 percent of your beta cells to supply sufficient insulin," Roep said. He said there have been a couple of rare cases where a patient had typical type 1 diabetes but could go through long periods without insulin injections. "Insulin needs can be a moving target, and if you have a lifestyle change it's very plausible that you have a lesser need for insulin, and you can deal with [diabetes] with the beta cells you have," Roep said.
Family or personal history. Your risk increases if you have prediabetes — a precursor to type 2 diabetes — or if a close family member, such as a parent or sibling, has type 2 diabetes. You're also at greater risk if you had gestational diabetes during a previous pregnancy, if you delivered a very large baby or if you had an unexplained stillbirth.
