Causes of Diabetes

Written by

Diabetes causes vary depending on your genetic makeup, family history, ethnicity, health, and environmental factors. There is no common diabetes cause that fits every type of diabetes as the causes of diabetes vary depending on the individual and the type.

For instance; the causes of type 1 diabetes vary considerably from the causes of gestational diabetes. Similarly, the causes of type 2 diabetes are distinct from the causes of type 1 diabetes. In fact, type 1 diabetes and type 2 diabetes causes are very different. Type 1 diabetes is an autoimmune condition where the pancreas cannot produce insulin, whereas type 2 diabetes is the body’s resistance to insulin.

DIFFERENT CAUSes


TYPE 1 DIABETES CAUSES

Type 1 diabetes is caused by the immune system destroying the cells in the pancreas that make insulin. This causes diabetes by leaving the body without enough insulin to function normally.

This is called an autoimmune reaction, or autoimmune cause because the body is attacking itself.

There are no specific diabetes causes, but the following triggers may be involved:

  • Viral or bacterial infection
  • Chemical toxins within food
  • Unidentified component causing an autoimmune reaction

The underlying genetic disposition may also be a type 1 diabetes cause.

TYPE 2 DIABETES CAUSES

Type 2 diabetes causes are usually multifactorial – more than one diabetes cause is involved. Often, the most overwhelming factor is a family history of type 2 diabetes.

This is the most likely type 2 diabetes cause.

There are a variety of risk factors for type 2 diabetes, any or all of which increase the chances of developing the condition.

These include:

  • Obesity
  • Living a sedentary lifestyle
  • Increasing age
  • Bad diet

Another type 2 diabetes causes such as pregnancy or illness can be type 2 diabetes risk factors.

GESTATIONAL DIABETES CAUSES

The causes of diabetes in pregnancy also known as gestational diabetes remain unknown. However, there are a number of risk factors that increase the chances of developing this condition:

  • Family history of gestational diabetes
  • Overweight or obese
  • Suffer from polycystic ovary syndrome
  • Have had a large baby weighing over 9lb

Causes of gestational diabetes may also be related to ethnicity – some ethnic groups have a higher risk of gestational diabetes.

OTHER DIABETES CAUSES

There are a variety of other potential diabetes causes. These include the following:

  • Pancreatitis or pancreatectomy as a cause of diabetes. Pancreatitis is known to increase the risk of developing diabetes, as is a pancreatectomy.
  • Polycystic Ovary Syndrome (PCOS). One of the root causes of PCOS is obesity-linked insulin resistance, which may also increase the risk of pre-diabetes and type 2 diabetes.
  • Cushing’s syndrome. This syndrome increases the production of the cortisol hormone, which serves to increased blood glucose levels An overabundance of cortisol can cause diabetes.
  • Glucagonoma. Patients with glucagonoma may experience diabetes because of a lack of equilibrium between levels of insulin production and glucagon production.
  • Steroid induced diabetes (steroid diabetes) is a rare form of diabetes that occurs due to prolonged use of glucocorticoid therapy.

PEOPLE WITH OBESITY BURN LESS CALORIES DURING THE DAY

  PEOPLE WITH OBESITY BURN LESS CALORIES DURING THE DAY Building on prior studies with healthy-weight participants, the new research includes different body sizes.         New research indicates that weight influences how and when bodies burn energy. An Oregon Health & Science University study published in the journal  Obesity  found people who have a healthy weight use more energy during the day, when most people are active and eat, while those who are obese spend more energy during the night when most people sleep. The study also found that during the day, those with obesity have higher levels of the hormone insulin -- a sign that the body is working harder to use glucose, an energy-packed sugar. "It was surprising to learn how dramatically the timing of when our bodies burn energy differed in those with obesity," said the study's first author, Andrew McHill, Ph.D., an assistant professor at the OHSU School of Nursing and the Oregon Institute of ...

WHAT CAUSES ITCHING, AND WHAT STOPS IT?

  WHAT CAUSES ITCHING, AND WHAT STOPS IT?         It can be a relief to scratch the occasional itch, but when itch gets out of control, it can become a severe health problem. How does the body know when to stop? Scientists at UC San Francisco are getting close to an answer. In a breakthrough that could transform how doctors treat conditions from eczema to allergies, they have discovered a feedback loop centered on a single immune protein called IL-31 that causes the urge to itch and dials back nearby inflammation. The findings, published on October 13th in  Science Immunology , lay the groundwork for a new generation of drugs that interact more intelligently with the body's innate self-regulating ability. Previous approaches suggested that IL-31 signals itch and promotes skin inflammation. However, the UCSF team discovered that nerve cells, or neurons, that respond to IL-31, triggering a scratch, also prevent immune cells from overreacting and causing more ...

A VEGAN DIET IMPROVES CARDIOVASCULAR HEALTH, ACCORDING TO A NEW STUDY

  A VEGAN DIET IMPROVES CARDIOVASCULAR HEALTH, ACCORDING TO A NEW STUDY         In a study with 22 pairs of identical twins, Stanford Medicine researchers and their colleagues have found that a vegan diet improves cardiovascular health in as little as eight weeks. Although it's well-known that eating less meat improves cardiovascular health, diet studies often need to be enhanced by genetic differences, upbringing, and lifestyle choices. By studying identical twins, however, the researchers were able to control for genetics and limit the other factors, as the twins grew up in the same households and reported similar lifestyles. "Not only did this study provide a groundbreaking way to assert that a vegan diet is healthier than the conventional omnivore diet, but the twins were also a riot to work with," said Christopher Gardner, Ph.D., the Rehnborg Farquhar Professor and a professor of medicine. "They dressed the same, they talked the same, and they had a banter ...
