What actually diabetes is? Diabetes is a disease in which our body unable to produce enough insulin or use insulin to process glucose. If an individual says that he or she have been diagnosed with diabetes, it means the cells unable to absorb glucose which used as source of energy.

We can understand about diabetes much better if we understand how the body regulates the glucose.

In non-diabetic people

Our digestive system breakdowns food into simpler compounds and most carbohydrate foods will end up as glucose. Glucose is source of energy for our body cells. Some amount of glucose will be stored in the liver, while most of it will enter the blood stream. From the blood stream, glucose will enter cells if that the cells have been attached with hormone called insulin, which is produced by the pancreas. Insulin is as a key that creates an opening in the cell membrane to allow the glucose to enter the cells.

Type 2 diabetes

In type-2 diabetes, cells unable to respond properly to insulin (insulin resistance) resulting decreases in amount of insulin that attach the cells. If less insulin attaches the cells, for sure amount of glucose that enter cells will be decrease. This causes high blood sugar in the blood streams hyperglycemia.

Type 1 diabetes

In type-1 diabetes, pancreas unable makes insulin at all because the body’ Glucose can’t enter the cells without insulin. So level of glucose in blood stream will be very high and causes harmful effect.

Other than this type-1 and type-2 diabetes, there is temporary form of diabetes that occurs during the second half of pregnancy called gestational diabetes. This is due to the interruption of the other hormones that stop insulin from working. Although this type of diabetes is temporary and can be treated with healthy eating alone, the changes that
particular person develops permanent diabetes is very high.

Symptoms of type-1 diabetes are more visible than type-2 diabetes. This is due to higher amount of glucose in the blood stream of type 1 diabetes patient because as mentioned before pancreas unable produce insulin at
all. Thirst, big appetite, frequent urination, blurred vision, fatigue, non-healing infection and weight loss are some of type-1 diabetes symptoms.
In type-2 diabetes, there might be no symptoms at all or milder symptoms may be present. The same goes to gestational diabetes patient, in which no symptoms can be seen but they could feel the tiredness.

Diabetes can cause complications on the other parts of our body. These complications usually develop silently and only visible after so many years.
