Lifestyle Choices

Ever heard of the phrase “choices have consequences”? Well, it’s not different when it comes to type 2 diabetes. For example, if you indulge in unhealthy eating habits, don’t care about watching your cholesterol levels, do not bother to stay physically fit, and are overweight you stand at a high risk of developing this medical condition. Why? Because leading an inactive lifestyle while being overweight can influence how your body utilizes insulin. 

Some unhealthy meal choices that can increase your likelihood of developing type 2 diabetes include a combination of low-fiber and high-fat meals.

The Role of Genetics

There is this misconception about hereditary diseases going around the world today. Some people tend to think that just because your mother or father has or had diabetes or other related medical condition, you’re automatically prone to get it. Wrong! What’s true though, is that in this scenario, your chances of developing type 2 diabetes are higher. 

According to health experts, there is a possibility of people inheriting type 2 diabetes, but there hasn’t yet been a confirmation of high-risk genes. So, if your family has a history of type 2 diabetes, it’s best to talk with your physician about how to prevent it from happening to you. 

Insulin Resistance

The above two causes (lifestyle choices and genetics), can cause your body to resist insulin. That means the insulin within your body system won’t be put into proper use.  

Yes, your body might be working just fine to produce the right amount of insulin you need to efficiently transport glucose to the cells, but that’s about it. Your body will end up resisting that same insulin! 

Results? The glucose ends building up in your blood system leading to type 2 diabetes-related symptoms. 

Insulin Resistance Isn’t Always the Cause of Type 2 Diabetes

While the main cause of type 2 diabetes is insulin resistance, which is mainly caused by poor lifestyle choices and genetics, it isn’t the only cause. In some cases, the patient’s body simply fails to produce enough insulin. And although the reasons behind this aren’t known yet, this uncommon cause of type 2 diabetes does exist. 


Type 2 diabetes is primarily caused by piling up glucose levels in your bloodstream. It’s a generally common medical condition easily triggered by poor lifestyle choices and genes. The good news is that type 2 diabetes can be prevented, treated, or even reversed with proper lifestyle changes and guidance from your doctor.
