How Diabetes Causes Kidney Disease – Each kidney is made up of millions of tiny filters called nephrons. Over time, high blood sugar from diabetes can damage blood vessels in the kidneys as well as nephrons so they don’t work as well as they should. Many people with diabetes also develop high blood pressure, which can damage kidneys too.
Is diabetes related to kidney failure?
What is diabetes? – Diabetes happens when your body does not make enough insulin or cannot use insulin properly. Insulin is a hormone. It controls how much sugar is in your blood. A high level of sugar in your blood can cause problems in many parts of your body, including your heart, kidneys, eyes, and brain.
- Over time, this can lead to kidney disease and kidney failure.
- There are two main types of diabetes.
- Type 1 diabetes generally begins when people are young.
- In this case, the body does not make enough insulin.
- Type 2 diabetes is usually found in adults over 40, but is becoming more common in younger people.
It is usually associated with being overweight and tends to run in families. In type 2 diabetes, the body makes insulin, but cannot use it well.
How long does it take for diabetes to cause kidney failure?
Kidney damage may begin 10 to 15 years after diabetes starts. As damage gets worse, the kidneys become worse at cleansing the blood. If the damage gets bad enough, the kidneys can stop working. Kidney damage can’t be reversed.
What are the signs of kidney failure in diabetics?
Stage 4 – This stage is a serious condition, and you’ll need to manage it closely to prevent kidney failure. Your kidneys may not work well, and you’ll likely get symptoms such as swelling in your hands and feet, and changes in how often you pee. You may also get high potassium levels and a buildup of acidity and phosphorus in your blood.
Can a diabetic recover from kidney failure?
Treatment options – There is no cure for diabetic nephropathy. Treatment must become ever more aggressive as the kidneys deteriorate towards failure. Medical options include:
Prevention – this is the best form of treatment and includes good control of blood glucose levels and blood pressure. Medications – including medications to reduce high blood pressure, particularly angiotensin converting enzyme (ACE) inhibitors and angiotensin receptor blockers to curb kidney damage. Dialysis – or artificial kidney treatment. End stage kidney failure is the failure of the kidney to function at all. Dialysis involves either shunting the patient’s blood through a special machine (haemodialysis) that helps remove the wastes while preserving water and salts, or removing wastes through fluid introduced into the abdomen (peritoneal dialysis). Dialysis is required several times every week for the rest of the person’s life. Kidney transplant – a healthy donor kidney, obtained either from someone who has died or from a relative or friend, replaces the function of the diseased kidneys.
How can you protect your kidneys from diabetes?
Foods to Limit – Eat less salt/sodium. That’s a good move for diabetes and really important for CKD. Over time, your kidneys lose the ability to control your sodium-water balance. Less sodium in your diet will help lower blood pressure and decrease fluid buildup in your body, which is common in kidney disease.
- Focus on fresh, homemade food and eat only small amounts of restaurant food and packaged food, which usually have lots of sodium.
- Look for low sodium (5% or less) on food labels.
- In a week or two, you’ll get used to less salt in your food, especially if you dial up the flavor with herbs, spices, mustard, and flavored vinegars.
But don’t use salt substitutes unless your doctor or dietitian says you can. Many are very high in potassium, which you may need to limit. Depending on your stage of kidney disease, you may also need to reduce the potassium, phosphorus, and protein in your diet.
Many foods that are part of a typical healthy diet may not be right for a CKD diet. Phosphorus is a mineral that keeps your bones strong and other parts of your body healthy. Your kidneys can’t remove extra phosphorus from your blood very well. Too much weakens bones and can damage your blood vessels, eyes, and heart.
Meat, dairy, beans, nuts, whole-grain bread, and dark-colored sodas are high in phosphorus. Phosphorus is also added to lots of packaged foods. The right level of potassium keeps your nerves and muscles working well. With CKD, too much potassium can build up in your blood and cause serious heart problems.
Oranges, potatoes, tomatoes, whole-grain bread, and many other foods are high in potassium. Apples, carrots, and white bread are lower in potassium. Your doctor may prescribe a potassium binder, a medicine that helps your body get rid of extra potassium. Eat the right amount of protein, More protein than you need makes your kidneys work harder and may make CKD worse.
But too little isn’t healthy either. Both animal and plant foods have protein. Your dietitian can help you figure out the right combination and amount of protein to eat.
Do all Type 2 diabetics have kidney problems?
If you have type 2 diabetes (T2D), you are at greater risk of developing kidney disease, a serious illness. In fact, diabetes is a leading cause for developing kidney disease. Have you found out if you are at risk for kidney disease? In the United States, 37 million adults are estimated to have kidney disease but only about 10 percent are diagnosed.
Can a diabetic get a new kidney?
Abstract – Chronic kidney disease (CKD) has become a real epidemic around the world, mainly due to ageing and diabetic nephropathy. Although diabetic nephropathy due to type 1 diabetes mellitus (T1DM) has been studied more extensively, the vast majority of the diabetic CKD patients suffer from type 2 diabetes mellitus (T2DM).
- Renal transplantation has been established as a first line treatment for diabetic nephropathy unless there are major contraindications and provides not only a better quality of life, but also a significant survival advantage over dialysis.
- However, T2DM patients are less likely to be referred for renal transplantation as they are usually older, obese and present significant comorbidities.
As pre-emptive renal transplantation presents a clear survival advantage over dialysis, all T2DM patients with CKD should be referred for early evaluation by a transplant center. The transplant center should have enough time in order to examine their eligibility focusing on special issues related with diabetic nephropathy and explore the best options for each patient.
- Living donor kidney transplantation should always be considered as the first line treatment.
- Otherwise, the patient should be listed for deceased donor kidney transplantation.
- Recent progress in transplantation medicine has improved the “transplant menu” for T2DM patients with diabetic nephropathy and there is an ongoing discussion about the place of simultaneous pancreas kidney (SPK) transplantation in well selected patients.
The initial hesitations about the different pathophysiology of T2DM have been forgotten due to the almost similar short- and long-term results with T1DM patients. However, there is still a long way and a lot of ethical and logistical issues before establishing SPK transplantation as an ordinary treatment for T2DM patients.
- In addition recent advances in bariatric surgery may offer new options for severely obese T2DM patients with CKD.
- Nevertheless, the existing data for T2DM patients with advanced CKD are rather scarce and bariatric surgery should not be considered as a cure for diabetic nephropathy, but only as a bridge for renal transplantation.
Keywords: Bariatric surgery, Cardiovascular complications, Diabetes, Renal transplantation, Pancreas transplantation Core tip: Kidney transplantation has been established as a first line treatment for patients with type 2 diabetes mellitus (T2DM) and diabetic nephropathy, as it is accompanied with a significant survival advantage over dialysis.
Pre-emptive living donor kidney transplantation should be the ultimate goal unless there are obvious contraindications and all patients should be referred for early evaluation by a transplant center. There is an ongoing debate about the exact role of simultaneous pancreas kidney transplantation. At the moment it should be offered only in well selected T2DM patients.
Bariatric surgery may serve as a bridge for renal transplantation for severely obese T2DM patients with chronic kidney disease.
At what blood sugar level does damage occur?
American Diabetes Association (ADA) guidelines advise ” lowering A1C to below or around 7%” and postprandial (after-meal) glucose levels to 180 mg/dl or below. But new research shows that these glucose levels damage blood vessels, nerves, organs, and beta cells.
An article by diabetes blogger Jenny Ruhl analyzes at what blood glucose level organ damage starts. According to Ruhl, research shows that glucose can do harm at much lower levels than doctors had thought.

This news could be discouraging or even terrifying.
If it’s hard to meet your current glucose goals, how will you reach tighter goals? Such news might make some people give up. But remember, a high postprandial or fasting reading won’t kill you. All we know is that higher numbers correlate with higher chances of complications.
- You have time to react.
- In fact, we could choose to look at this as good news.
- We all know of people who developed complications despite “good control.” But complications are not inevitable; it’s just that so-called “good control” wasn’t really all that good.
- First, the numbers.
- Post-meal blood sugars of 140 mg/dl and higher, and fasting blood sugars over 100 mg/dl cause permanent organ damage and cause diabetes to progress,” Ruhl writes.
For nerve damage, University of Utah researchers studied people with painful sensory neuropathy, or nerve damage. They found that participants who did not have diabetes but who had impaired glucose tolerance on an oral glucose tolerance test, or OGTT, (meaning that their glucose levels rose to between 140 mg/dl and 200 mg/dl in response to drinking a glucose-rich drink) were much more likely to have a diabetic form of neuropathy than those with lower blood glucose levels.
The higher these OGTT numbers go, the more nerve damage is found, according to Johns Hopkins Hospital researchers. The OGTT gives a good idea of how high after-meal blood glucose levels are likely to be. Glucose can also start killing beta cells at levels below 140. One study found that people with fasting blood glucose from 110–125 (within the official “prediabetic” range) had already lost up to 40% of their beta cell mass.
Italian researchers found that even with glucose levels in the supposedly “normal” range, beta cells started to fail, Ruhl says that researchers “found that with every small increase in the 2-hour glucose tolerance test result, there was a corresponding increase inbeta cell failure.
- The higher a person’s blood sugar rose within ‘normal’ range, the more beta cells were failing.” Failing beta cells will lead to worsening diabetes, a truly vicious cycle.
- Slightly elevated glucose has also been shown to cause eye damage (“retinopathy”) and increased rates of heart disease, kidney damage, and stroke.
Where Does High Start? Studies like the ones Ruhl quotes and others indicate that damage occurs with even slightly elevated blood glucose. But what can you do about that? Is it reasonable to try to keep glucose at normal levels all the time? It seems for some people, that course would lead to frustration and burnout.
- In fact, ADA says that older, sicker people should have even less strict goals.
- How do you set reasonable goals for yourself? Keeping normal numbers may require extraordinary effort.
- It may require very low carbohydrate intake.
- It may not be possible for you.
- If you’re taking insulin or drugs in the sulfonylurea or meglitinide classes, aiming too low can put you at risk of hypoglycemia (low blood glucose).
The whole thing can make you crazy, because sometimes numbers will go up for no apparent reason. As a result, most people set less-demanding goals for themselves. If they can keep their postprandial glucose under 180 and their fasting below 120, they’re OK, and the ADA agrees.
- There’s nothing wrong with that.
- People can trade off how low they want their blood glucose against how much work they are willing to do and how many foods they’re willing to cut back or give up.
- They are adding to their risk, but, to me, quality of life is the most important thing.
- Important note: Bringing blood glucose down by means of multiple drugs has NOT been shown to decrease complications much.
Two huge studies, the ACCORD and ADVANCE trials showed this. But people who manage to keep normal or near-normal numbers through healthy eating and living and intelligent use of medicines seem to live long, relatively healthy lives. They can even reverse type 2 or the complications of Type 1, even if they have spent years with elevated blood glucose before getting them under control.

- Your kidneys clean your blood.
- If they are damaged, waste and fluids build up in your blood instead of leaving your body.
- Idney damage from diabetes is called diabetic nephropathy.
- It begins long before you have symptoms.
- People with diabetes should get regular screenings for kidney disease.
- Include a urine test to detect protein in your urine and a blood test to show how well your kidneys are working.
If the damage continues, your kidneys could fail. In fact, diabetes is the most common cause of in the United States. People with kidney failure need either or a, You can slow down kidney damage or keep it from getting worse. Controlling your blood sugar and blood pressure, taking your medicines and not eating too much can help.
