Is it Blood Sugar or the Pancreas?

We all know diabetes raises your risk of developing Chronic Kidney Disease. But why? What’s the mechanism behind the fact? As far as I’m concerned, it’s time to find out.

Let’s start with diabetes. The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), part of the National Institutes of Health (NIH), which in turn is part of The U.S. Department of Health and Human Services at https://www.niddk.nih.gov/health-information/diabetes/overview/what-is-diabetes offers this explanation.

“Diabetes is a disease that occurs when your blood glucose, also called blood sugar, is too high. Blood glucose is your main source of energy and comes from the food you eat. Insulin, a hormone made by the pancreas, helps glucose from food get into your cells to be used for energy. Sometimes your body doesn’t make enough—or any—insulin or doesn’t use insulin well. Glucose then stays in your blood and doesn’t reach your cells.

Over time, having too much glucose in your blood can cause health problems. Although diabetes has no cure, you can take steps to manage your diabetes and stay healthy.

Sometimes people call diabetes ‘a touch of sugar’ or ‘borderline diabetes.’”

Having just had a tumor removed from my pancreas, I’m well aware that it produces insulin as well as digestive enzymes. Without a pancreas to produce insulin, you would need insulin injections several times a day.

I got what diabetes is, but how it causes CKD was still not clear.

Well, not until I read the following from The American Diabetes Association at https://www.diabetes.org/diabetes/complications/kidney-disease-nephropathy.

“When our bodies digest the protein we eat, the process creates waste products. In the kidneys, millions of tiny blood vessels (capillaries) with even tinier holes in them act as filters. As blood flows through the blood vessels, small molecules such as waste products squeeze through the holes. These waste products become part of the urine. Useful substances, such as protein and red blood cells, are too big to pass through the holes in the filter and stay in the blood.

Diabetes can damage this system. High levels of blood sugar make the kidneys filter too much blood. All this extra work is hard on the filters. After many years, they start to leak and useful protein is lost in the urine. Having small amounts of protein in the urine is called microalbuminuria.

When kidney disease is diagnosed early, during microalbuminuria, several treatments may keep kidney disease from getting worse. Having larger amounts of protein in the urine is called macroalbuminuria. When kidney disease is caught later during macroalbuminuria, end-stage renal disease, or ESRD, usually follows.

In time, the stress of overwork causes the kidneys to lose their filtering ability. Waste products then start to build up in the blood. Finally, the kidneys fail. This failure, ESRD, is very serious. A person with ESRD needs to have a kidney transplant or to have the blood filtered by machine (dialysis).”

Hmmm, now that we know what diabetes is and how it can cause CKD, maybe we need to look at ways to attempt to avoid diabetes.

  • Losing weight and keeping it off. Weight control is an important part of diabetes prevention. You may be able to prevent or delay diabetes by losing 5 to 10 percent of your current weight. For example, if you weigh 200 pounds, your goal would be to lose between 10 to 20 pounds. And once you lose the weight, it is important that you don’t gain it back.
  • Following a healthy eating plan. It is important to reduce the amount of calories you eat and drink each day, so you can lose weight and keep it off. To do that, your diet should include smaller portions and less fat and sugar. You should also eat a variety of foods from each food group, including plenty of whole grains, fruits, and vegetables. It’s also a good idea to limit red meat, and avoid processed meats.
  • Get regular exercise. Exercise has many health benefits, including helping you to lose weight and lower your blood sugar levels. These both lower your risk of type 2 diabetes. Try to get at least 30 minutes of physical activity 5 days a week. If you have not been active, talk with your health care professional to figure out which types of exercise are best for you. You can start slowly and work up to your goal.
  • Don’t smoke. Smoking can contribute to insulin resistance, which can lead to type 2 diabetes. If you already smoke, try to quit.
  • Talk to your health care provider to see whether there is anything else you can do to delay or to prevent type 2 diabetes. If you are at high risk, your provider may suggest that you take one of a few types of diabetes medicines.”

This is a list from NIH: National Institute of Diabetes and Digestive and Kidney Diseases posted on MedLinePlus at https://medlineplus.gov/howtopreventdiabetes.html. Notice it’s mentioned that this is for type 2 diabetes.

There are 11 different kinds of diabetes. Types 1 and 2 are the most common. WebMD at https://www.webmd.com/diabetes/guide/types-of-diabetes-mellitus#1 explains what type 1 and 2 are.

Type 1 diabetes is an autoimmune condition. It’s caused by the body attacking its own pancreas with antibodies. In people with type 1 diabetes, the damaged pancreas doesn’t make insulin…. With Type 2 diabetes, the pancreas usually produces some insulin. But either the amount produced is not enough for the body’s needs, or the body’s cells are resistant to it. Insulin resistance, or lack of sensitivity to insulin, happens primarily in fat, liver, and muscle cells.”

This is all starting to make sense.

Until next week,

Keep living your life!
