7 Ways Chronic Kidney Disease, Diabetes, and Hypertension Are Related

Chronic Kidney Disease Diabetes and Hypertensions Link

    Chronic kidney disease can come from several health conditions, habits, and genetic factors. Still, the two most common are diabetes and hypertension.

    These two conditions are well noted as primary chronic kidney disease causes, as they impact your kidneys’ health in detrimental ways.

    Now, having one or both of these conditions doesn’t automatically lead to the development of chronic kidney disease. Yet, once you know more about how diabetes and hypertension can badly affect kidney health, you’ll be better equipped to minimize your risk. You’ll want to do everything you can to control these illnesses, which damage the kidneys.

    Understanding Chronic Kidney Disease Causes

    Chronic kidney disease occurs when your kidneys can no longer filter out toxins and other waste products from your blood with the same efficiency. Any condition that either increases the need for filtration or interferes with regular kidney function can become a big problem.

    Diabetes and hypertension are common chronic kidney disease causes because they have a direct negative impact on your kidneys. When they occur together, your risk of kidney damage is much higher than if you had either disease on its own. So keeping these conditions under control is very important.

    Diabetes and Your Kidneys

    Kidney damage caused by diabetes is known as diabetic kidney disease. It’s a very prevalent condition, with nearly one in every three people who have diabetes also developing some kidney damage.

    Still, not all people who have diabetes are guaranteed to get kidney disease. The difference typically lies in how well you take care of your body after a diabetes diagnosis. Doing so will help to understand the connection between the two conditions.

    Blood Glucose Levels

    When you have diabetes, your body cannot produce or use insulin at the same rate as a non-diabetic person.

    Insulin is responsible for breaking down sugar in your bloodstream. Without it, your blood sugar levels rise too high, which can have adverse effects. This includes nerve damage, heart disease, vision problems, and, of course, kidney damage.

    How Diabetes Causes Kidney Disease

    Having high blood glucose levels for an extended time is known as hyperglycemia. It can damage your blood vessels, interfering with your body’s ability to transport blood to your organs.

    Having a lot of glucose in your blood also reduces the amount of nitric oxide. This is a vasodilator, which means it widens your blood vessels and improves blood flow. Without nitric oxide, blood vessels remain narrow, which correlates with high blood pressure.

    Hyperglycemia may damage blood vessels in or near your kidneys. This means your kidneys aren’t getting the blood flow they need to function correctly and can no longer efficiently filter waste out of your bloodstream.

    Hypertension and Your Kidneys

    Hypertension is another name for high blood pressure. You’ve probably had your blood pressure taken before, but what do those numbers mean practically?

    Your blood pressure is a measure of the force of your blood cells as they push against the blood vessels in your body. When pressure is normal, blood cells pass through your arteries normally. 

    When pressure is too high or too low, it harms the regular blood supply to your organs.

    Both high and low blood pressure can cause concern, but high blood pressure is more likely to cause damage to your kidneys. This is because it can have a lasting impact on your blood vessels and their effectiveness at transporting blood throughout your body.

    How Hypertension Causes Kidney Disease

    Like diabetes, hypertension can also damage your blood vessels. When your blood pressure is high, your heart and the circulatory system must work harder to keep your blood pumping.

    Over time, this increased workload and decreased efficiency cause damage to the blood vessels. The blood vessels simply can’t keep up with the higher blood pressure. Instead, they become overworked and sustain damage over time.

    The blood flow to the kidneys is impaired, resulting in chronic kidney disease and an increased risk of conditions like heart attacks and stroke.


    While diabetes and hypertension are strongly correlated with chronic kidney disease, this doesn’t mean kidney damage is an inevitable outcome.

    You can protect your kidneys by managing these conditions efficiently, ensuring they don’t get any worse. This can be accomplished by exercising more frequently, making nutritional decisions that feed your microbiome, and cutting out heavily processed foods from your diet.

    This way, you can manage and prevent a potential source of your kidney deterioration.
