Diabetes and the Effects on the Body

Diabetes is all about blood sugar and insulin. When blood sugar levels get out of control, it opens the door to serious diseases and organ damage in your body. 

Here’s how.

After a meal, your body breaks down food and drink into proteins, fats and a form of sugar called glucose. Glucose stays in your blood stream until it is absorbed by cells throughout the body. Glucose gives cells the energy they need to fuel your organs and muscles.  

Insulin (a hormone made by the pancreas) helps cells absorb glucose. Without it, glucose stays in the bloodstream and cells starve.

When a person has diabetes, the pancreas makes too little insulin, none at all, or the insulin it does make can’t be used effectively. As a result, blood glucose levels rise out of control and cause serious health issues.

Diabetes takes a toll on your: 

  • Eyes (cataracts, vision blurriness, seeing spots, and even blindness)
  • Kidneys (urinating too much or not enough, injury to kidneys, and kidney shut down that leads to dialysis)
  • Blood flow (poor circulation and high blood pressure)
  • Cholesterol (high levels that can cause heart attacks, strokes)
  • Nerves (painful stinging or loss of feeling)
  • Skin (sores, wounds that don’t heal, and infections that can lead to amputation)

Diabetes can’t be cured. Still, medicine, eating healthy, staying active and working closely with your doctor can lower its affect so you can live well.
