Causes and Symptoms of Type 2 Diabetes

Causes and Symptoms of Type 2 Diabetes are mostly ignored and this should not be the case.Many people develop Type 2 Diabetes symptoms in midlife or in older age and gradually develop symptoms in stages, especially if the condition goes untreated and worsens. Diabetes is several diseases that involve problems with the hormone insulin. It is a group of metabolic disorders in which there are high blood sugar levels over a prolonged period. There are two main types of diabetes, known as “Type 1 Diabetes” and “Type 2 Diabetes”. Type 2 Diabetes is the most common type of Diabetes. Of all people with diabetes, 90% have Type 2 Diabetes. Type 2 Diabetes usually happens in older people, but recently, more and more younger people, and sometimes even children, develop Type 2 Diabetes.

Common Causes of Type 2 Diabetes

  1. Genetics

Type 2 Diabetes can be hereditary. This doesn’t mean that if your parents have (or had) Type 2 Diabetes, you’re guaranteed to develop it; instead, it means that you have a greater chance of developing this type.

  1. Lifestyle

Genes play a role in Type 2 Diabetes, but lifestyle choices are also important. Research has shown that you can have a genetic mutation that may make you susceptible to Type 2 Diabetes, but if you take good care of your body, you may not develop diabetes.

Lifestyle choices that affect the development of Type 2 Diabetes include:

  • Unhealthy meal plans– A meal plan filled with high-fat foods and lacking fibre (which from grains, vegetables, and fruits) increases the likelihood of Type 2.
  • Lack of exercise– Physical activity has many benefits, one of them being that it can help you avoid Type 2 Diabetes, if you’re susceptible.
  • Being overweight/obese– Lack of exercise and unhealthy meal choices may lead to obesity. Being overweight makes it more likely that you’ll become insulin resistant and may also lead to many other health conditions.

While not everyone with Type 2 Diabetes is overweight, obesity and lack of physical activity are two common risk factors of this form of Diabetes.

  1. Insulin Resistance

With Type 2 Diabetes, your body either resists the effects of insulin (a hormone that regulates the movement of sugar into your cells) or doesn’t produce enough insulin to maintain a normal glucose level. Type 2 Diabetes has several causes, genetics and lifestyle are the most well-known causes. A combination of these factors can cause insulin resistance, which is when your body doesn’t use insulin as well as it should. If your body is insulin resistant, it doesn’t use insulin properly. Your body may produce enough insulin to transport the glucose to the cells and resist it at the same time. When you are insulin resistant, Glucose builds up in the blood leading to the symptoms associated with Type 2 Diabetes.

It is possible to have type 2 and not be insulin resistant. You can also have a form of Type 2 Diabetes where your body simply doesn’t produce enough insulin.


In a healthy person, Insulin is released by the pancreas (an organ behind the stomach) to help the body store and use the sugar from the food you eat. When there isn’t enough insulin or the insulin is not used as it should be, glucose (sugar) can’t get into the body’s cells and builds up in the bloodstream instead. When glucose builds up in the bloodstream instead of going into cells, it causes damage in multiple areas of the body. Also, since cells aren’t getting the glucose they need, they can’t function properly.

Symptoms of Type 2 Diabetes

The signs and symptoms of Type 2 Diabetes often develop slowly. You can have Type 2 Diabetes for years and not know that.

  • Increased hunger– Without enough insulin to move sugar into your cells, your muscles and organs lose energy. This normally triggers serious hunger.
  • Weight loss-Despite eating more than usual to relieve hunger, you may also lose weight.
  • Increased thirst and Frequent Urination-Excess sugar building up in your bloodstream causes fluid to be pulled from the tissues. This may leave you very thirsty. Thus, you may drink and urinate more than usual. If the body is unable to metabolize glucose, the body uses alternative fuels stored in muscles and fat. Calories are lost as excess glucose is released in the urine.

  • Fatigue-If your cells are deprived of sugar, you may become tired and irritable.
  • Blurred vision– If your blood sugar is too high, fluid may be pulled from the lenses of your eyes. This may affect your ability to focus.
  • Slow-healing sores or frequent infections-Type 2 diabetes affects your ability to heal and resist infections.

If you notice any of the above mentioned Type 2 Diabetes symptoms, see your doctor.
