Causes And Symptoms Of Diabetes Mellitus Type-2

Diabetes mellitus type-2

Diabetes or diabetes mellitus is a problem in which the blood sugar levels rise higher than normal. This is also called hyperglycemia or insulin dependent diabetes. Type -2 diabetes is the most common form of diabetes. It has various causes and symptoms. About 27 million Americans are suffering with Diabetes mellitus type-2.

If you have type-2 diabetes, your body does not make enough insulin. Insulin is important for blood cells to open for glucose to enter. But due to lack of insulin cells do not open. The sugar gets collected in the blood. This is called insulin resistance or type -2 diabetes.

Some common symptoms are

  • Increased thirst: Increased blood sugar can make diabetics dehydrated making them thirsty over and over again.
  • Frequent urination: Due to excessive thirst, diabetics drink more water so they have more urination.
  • Unexplained weight loss: The body is not able to utilize glucose for energy. The body uses fat to extract energy causing weight loss.
  • Increased hunger: Diabetics are unable to use glucose so they need more food for glucose. So they start feeling hungry all the time since cells starve for glucose.
  • Wounds that do not heal: Increased blood sugar levels affect circulation. When blood flow to injured tissue does not happen, wounds do not heal fast.

Causes of diabetes type-2

People generally develop this type of diabetes due to lifestyle and genetic factors. Some of these factors can be controlled. But factors such as age, female gender, and genetics cannot be controlled.


Lifestyle factors are key to leading to the disease. Obesity and overweight, lack of physical activity, poor diet, stress and urbanization can be some factors that might cause this type -2 diabetes. Most cases of this disease are due to excess weight.

Consumption of sugared drinks in excess, can increase the risk. Saturated and trans fats inclusion in the diet can also lead to the disease. It is better eating foods that contain poly saturated and mono saturated foods.


Most cases of diabetes involve many genes. Each can be a contributor to one becoming a diabetic. Identical twins develop diabetes more easily than non identical twins. More than 36 genes have been known to cause diabetes.

Medical conditions
