Our body needs energy to perform its daily duties and remain active and healthy. Our body gets the energy provided by glucose from the food we eat every day. Glucose has to get into the cells of our body to provide energy and this done by a hormone known as insulin.

And insulin is secreted from the pancreas. Insufficient secretion of insulin could lead to type 2 diabetes. In this article, we will try and understand more about this form of diabetes and also look into the effects of type 2 diabetes.

Insufficient Supply of Insulin

When a person suffers from diabetes he or she may not be able to get the right amount of insulin. When the pancreas is unable to make ANY insulin then a person is said to be suffering from type 1-diabetes.

A person is known to be suffering from type 2 diabetes when the pancreas does produce insulin, but the quantity produced is inadequate.

Without the right amount of insulin in the body, the glucose in the blood cannot be fully converted into energy and made fit to be used by the blood cells. This leads to a situation where the glucose or sugar levels in the body are higher than normal.

However, high levels of blood sugar in the body could be dangerous and critical if it is left untreated or uncontrolled for long periods.

This could lead to dangerous complications. It is therefore important to remedy the situation and keep blood sugar levels under control in case of type 2 diabetes.


Pancreatic cells in patients with type 1 diabetes lose their ability to produce insulin. The ability to produce insulin in patients with type 2 diabetes is not completely lost, but the amount produced does not reduce blood sugar in time.

What Causes Type 2 Diabetes

There could be several reasons can cause type 2 diabetes. However, in most cases, it is caused by lifestyle and genetics. A combination of genetics and lifestyle can lead to insulin resistance, over some time. The body makes insufficient and inefficient use of insulin and this is what causes type 2 diabetes.

1. Hereditary reasons are one of the main reasons for type 2 diabetes.

However, it would be wrong to assume that if either of your parents suffers from this condition, you are bound to get it. It just would put you at a higher risk of getting this condition of blood sugar.

But it is still not clear as to the exact genes that cause the transfer of type 2 diabetes from parents to their children.

2. Lifestyle also has a role to play in increasing the risk.

For example, you could have a genetic mutation that makes you susceptible to type 2 diabetes, but if you can have a healthy lifestyle with good food and exercise habits, you might be able to prevent the genetic mutation turning into a case of type 2 diabetes.

If the persons are overweight, obese, with high BMI and a sedentary lifestyle, they are at a higher risk of being impacted by type 2 diabetes.

Genetics is like a loaded bullet, and lifestyle is the trigger.

Typical Symptoms of Type 2 Diabetes

Uncontrolled blood sugar in the body caused by type 2 diabetes is fraught with dangers and it could impact almost the entire body. The problem with the symptoms is that they are difficult to identify and they might look too general.

You must try and understand some of the classic symptoms of type 2 diabetes and here are a few of them:

  • Excessive thirst.
  • Excessive urination, especially during the night.
  • Feeling tired and a feeling of fatigue.
  • Increased blood pressure
  • Delay in wound healing.
  • Protein in the urine.
  • Visual disturbances
  • Sweet-smelling breath
  • Malfunctioning of the pancreas
  • Bloating, nausea and heartburn because of poor glucose management.

Effects of Type 2 Diabetes

Symptoms apart, the effects of type 2 diabetes could be debilitating and even life-threatening if it is not addressed early and adequately. Here are some of the most common effects of Type-II diabetes.

  1. Damage to the kidney. It reduces the efficient functioning of the kidneys and negatively impacts their ability to filter waste products in the blood.
  2. High blood pressure. This puts additional strain on the heart. High blood sugar levels could also lead to fatty deposits along the blood vessel walls and arteries. This could restrict blood flow.
  3. Lead to damage to your skin. The skin is the largest organ of our body. High blood sugar could lead to dehydration.
  4. Diabetic neuropathy. This means damage to the nerves and the central nervous system.

Other side effects include impaired reproductive systems, eye vision impairment, increased risk of blindness, strokes and so on.

How to Prevent It?

  • You should learn to be proactive rather than being reactive when it comes to preventing type 2 diabetes. There is something known as Risk Assessment Test which helps find out the chances of a person being impacted by type 2 diabetes.
  • Weight management is important. Avoid excess fat deposits especially around the abdomen. This could lead to the body’s resistance to insulin.
  • Regular exercise is very good. Give importance to moderate activity and exercising daily. This will help burn calories and bring down blood sugar levels to normal and manageable levels.
  • A healthy and balanced diet is important. Reduce fat intake and also carbohydrate intake. Avoid trans fats and saturated fats. Get into the habit of eating more vegetables, healthy fruits, and fiber-rich food items.
  • Limit the intake of alcohol and give up smoking.
  • Be regular with your doctor’s checkups.

The Final Word

Identifying the risk factors of diabetes-2 and being aware of the effects of type 2 diabetes would certainly help you in managing this condition.

Diabetes-2 cannot be cured but it certainly can be managed very effectively.
