Does Ketosis Cause Kidney Damage?
The ‘Lean for Life’ program is mildly ketotic, and only for a brief portion of the program. It has not been associated with kidney damage or disease in individuals who have normally functioning kidneys. Concerns regarding undue stress on the kidneys are often aimed at very low carbohydrate, very high protein ketogenic diets. Few studies have shown any actual damage, however. (Note: Although the Weight Loss portion of the ‘Lean for Life’ program is mildly ketogenic, it is not considered to be exceptionally “high protein” for most individuals.) Dietary ketosis is among the most maligned and misunderstood concepts in nutrition medicine. Particularly among researchers who don’t actually treat patients, ketosis (the presence of ketone bodies in the urine) is often confused with ketoacidosis, which is a life-threatening build-up of ketone bodies due to muscle wasting and dehydration as in states of shock or uncontrolled Type 1 diabetes. In the Type 1 diabetic, the absence of insulin leads to a toxic build-up of blood glucose and an extreme break-down of fat and muscle tissue. This condition doesn’t occur in individuals who have even a small amount of insulin, whether from natural production or artificially administered. Whereas patients in ketoacidosis are closely monitored in Intensive Care Units, individuals in ketosis are amongst the healthy, active population. Dietary ketosis is a natural adjustment to the body’s reduced intake of carbohydrates as the body shifts its primary source of energy from carbohydrates to stored fat. The presence of insulin keeps ketone production in check so that a mild, beneficial ketosis is achieved. Blood glucose levels are stabilized within a normal range and there is no break-down of healthy muscle tissue. It would be diffi Continue reading >>
How Does Drinking Water Affect The Kidneys?
Kidney filters the waste. The problem here is no body ever made an attempt to define the waste in the parlance of working of the kidney. Kidneys maintain balance among various minerals, hormones and vitamins in the body. There is no item in blood which is waste by itself. If a person drinks excessive water majority of the minerals are diluted. That will increase the need to take supplements. But the minerals balancing is a complex system. No humans can make supplements which will meet the demands of the body. Supplements that a person may take may also be excessive resulting in excessive inflammation caused to flush out the supplements. It is complex if humans want to take charge of the body in complete disregard to the basic principles of the working of human body. Read more about benefits of hydration / dehydration at my blog.

Ketosis & Kidney Failure
Ketosis happens when your body resorts to fat for energy after your stored carbohydrates have been burned out. It often occurs when people fast and exercise. But most commonly, ketosis occurs in people who eat low-carb, high-protein diets, which are also called ketogenic diets. There’s some evidence that ketosis can tax your kidneys, leading to kidney stones and low blood pressure. In diabetics, a variant of ketosis can be fatal. However, a small but growing group of health professionals say ketosis is not the poison you’ve been lead to think it was, and it may be better for you than high-carbohydrate eating. Your specific dietary habits are best advised by your healthcare provider or nutritionist. Video of the Day Ketosis happens when you get a buildup of a substance known as ketones, or ketone bodies in your blood. They are released when your body’s carbohydrate stores run out and you have to break down fat stores for energy. Dieters tend to deliberately cause ketosis because it makes you feel less hungry. However, ketosis also makes you feel tired and sluggish, because as "Medical News Today" reports, ketones aren’t the most efficient source of energy, especially for your brain. Ketosis can also harm your kidneys. Annually, more than 100,000 people are diagnosed with kidney failure in the United States, reports the National Institute of Diabetes and Digestive and Kidney Diseases, or NIDDK. The condition is marked by the inability of your kidneys to do their job of eliminating wastes. One treatment for kidney failure is dialysis, a draining and lengthy artificial blood cleansing process. Another option is a kidney transplant. The NIDDK states that the cost of care for patients with kidney failure reached close to $32 billion in 2005. The federal government sub Continue reading >>
Complications caused by diabetes People with diabetes must routinely monitor and regulate their blood sugar. No matter how careful you may be, there’s still a possibility that a problem might arise. There are two types of complications you may experience: acute and chronic. Acute complications require emergency care. Examples include hypoglycemia and ketoacidosis. If left untreated, these conditions can cause: seizures loss of consciousness death Chronic complications occur when diabetes isn’t managed properly. Diabetes causes high blood sugar levels. If not controlled well over time, high blood sugar levels can damage various organs, including the: eyes kidneys heart skin Unmanaged diabetes can also cause nerve damage. People with diabetes can experience sudden drops in their blood sugar. Skipping a meal or taking too much insulin or other medications that increase insulin levels in the body are common causes. People who are on other diabetes medications that do not increase insulin levels are not at risk for hypoglycemia. Symptoms can include: blurry vision rapid heartbeat headache shaking dizziness If your blood sugar gets too low, you can experience fainting, seizures, or coma. This is a complication of diabetes that occurs when your body cannot use sugar, or glucose, as a fuel source because your body has no insulin or not enough insulin. If your cells are starved for energy, your body begins to break down fat. Potentially toxic acids called ketone bodies, which are byproducts of fat breakdown, build up in the body. This can lead to: dehydration abdominal pain breathing problems Diabetes can damage blood vessels in the eyes and cause various problems. Possible eye conditions may include: Cataracts Cataracts are two to five times more likely to develop in people Continue reading >>
Severe Acute Renal Failure In A Patient With Diabetic Ketoacidosis.
Abstract Acute renal failure (ARF) is a rare but potentially fatal complication of diabetic ketoacidosis (DKA). Early recognition and aggressive treatment of ARF during DKA may im-prove the prognosis of these patients. We present a case report of a 12 year old female admitted to the hospital with severe DKA as the 1s t manifestation of her diabetes mellitus. She presented with severe metabolic acidosis, hypophosphatemia, and oliguric ARF. In addition, rhabdomyolysis was noted during the course of DKA which probably contributed to the ARF. Management of DKA and renal replacement therapy resulted in quick recovery of renal function. We suggest that early initiation of renal replacement therapy for patients with DKA developing ARF may improve the potentially poor outcome of patients with ARF associated with DKA.

Diabetes mellitus is the name given to a group of conditions whose common hallmark is a raised blood glucose concentration (hyperglycemia) due to an absolute or relative deficiency of the pancreatic hormone insulin. In the UK there are 1.4 million registered diabetic patients, approximately 3 % of the population. In addition, an estimated 1 million remain undiagnosed. It is a growing health problem: In 1998, the World Health Organization (WHO) predicted a doubling of the worldwide prevalence of diabetes from 150 million to 300 million by 2025. For a very tiny minority, diabetes is a secondary feature of primary endocrine disease such as acromegaly (growth hormone excess) or Cushing’s syndrome (excess corticosteroid), and for these patients successful treatment of the primary disease cures diabetes. Most diabetic patients, however, are classified as suffering either type 1 or type 2 diabetes. Type 1 diabetes Type 1 diabetes, which accounts for around 15 % of the total diabetic population, is an autoimmune disease of the pancreas in which the insulin-producing β-cells of the pancreas are selectively destroyed, resulting in an absolute insulin deficiency. The condition arises in genetically susceptible individuals exposed to undefined environmental insult(s) (possibly viral infection) early in life. It usually becomes clinically evident and therefore diagnosed during late childhood, with peak incidence between 11 and 13 years of age, although the autoimmune-mediated β-cell destruction begins many years earlier. There is currently no cure and type 1 diabetics have an absolute life-long requirement for daily insulin injections to survive. Type 2 diabetes This is the most common form of diabetes: around 85 % of the diabetic population has type 2 diabetes. The primary prob Continue reading >>
Incidence And Characteristics Of Acute Kidney Injury In Severe Diabetic Ketoacidosis
Abstract Acute kidney injury is a classical complication of diabetic ketoacidosis. However, to the best of our knowledge, no study has reported the incidence and characteristics of acute kidney injury since the consensus definition was issued. Retrospective study of all cases of severe diabetic ketoacidosis hospitalised consecutively in a medical surgical tertiary ICU during 10 years. Patients were dichotomised in with AKI and without AKI on admission according to the RIFLE classification. Clinical and biological parameters were compared in these populations. Risk factors of presenting AKI on admission were searched for. Results Ninety-four patients were included in the study. According to the RIFLE criteria, 47 patients (50%) presented acute kidney injury on admission; most of them were in the risk class (51%). At 12 and 24 hours, the percentage of AKI patients decreased to 26% and 27% respectively. During the first 24 hours, 3 patients needed renal replacement therapy. Acute renal failure on admission was associated with a more advanced age, SAPS 2 and more severe biological impairments. Treatments were not different between groups except for insulin infusion. Logistic regression found 3 risk factors of presenting AKI on admission: age (odds ratio 1.060 [1.020–1.100], p<0.01), blood glucose (odds ratio 1.101 [1.039–1.166], p<0.01) and serum protein (odds ratio 0.928 [0.865–0.997], p = 0.04). Acute kidney injury is frequently associated with severe diabetic ketoacidosis on admission in ICU. Most of the time, this AKI is transient and characterised by a volume-responsiveness to fluid infusion used in DKA treatment. Age, blood glucose and serum protein are associated to the occurrence of AKI on ICU admission. Figures Citation: Orban J-C, Maizière E-M, Ghaddab A, V Continue reading >>
Renal Function And Effects Of Partial Rehydration During Diabetic Ketoacidosis
Although diabetic ketoacidosis is characterized by increased renal excretion of glucose, ketone bodies, and nitrogenous compounds, there are few quantitative studies pertaining to renal function during this state. Therefore, renal function was studied in 10 adult patients in moderate to severe diabetic ketoacidosis before insulin administration. Admission plasma concentrations were: glucose 21.4 (9.2–39.4) mM or 386 (166–710) mg/dl, acetoacetate 3.0 (1.3–7.4) mM, beta-hydroxybutyrate 7.9 (2.9–15.2) mM, acetone 4.4 (1.3–8.9) mM, and HCO3 12.8 (9.5–17.8) mM. Arterial blood pH was 7.28 (7.21–7.38). Partial rehydration was achieved with 0.45% saline. Inulin was used to measure GFR. Renal clearance of acetoacetate, beta-hydroxybutyrate, acetone, glucose, and urinary excretion of nitrogenous compounds were determined. Partial rehydration reduced plasma glucose concentration, primarily because of renal excretion, amounting to 384 ± 73 μmol/min or 69 ± 13 mg/min. Partial rehydration had no effect on plasma ketone bodies, on bicarbonate or urea concentrations, or on arterial pH. Partial rehydration had no effect on ketone body or nitrogenous compound excretory rates. Reabsorptive rates of acetoacetate, beta-hydroxybutyrate, acetone, and glucose increased linearly with their filtered loads, and no maximal renal tubular transport rates were demonstrated for any ketone body or glucose. Because renal absorption of ketone bodies was less than 100%, ketonuria increased as filtered loads increase. Unlike ketone bodies, glucose reabsorptive rate was directly related to GFR. Total renal excretion of nitrogen in the forms of urea, ammonium, creatinine, and uric acid amounted to 16 ± 2 mg/min. This huge loss of body nitrogen reflected ongoing protein catabolism and not he Continue reading >>
Diabetic Ketoacidosis (dka) - Topic Overview
Diabetic ketoacidosis (DKA) is a life-threatening condition that develops when cells in the body are unable to get the sugar (glucose) they need for energy because there is not enough insulin. When the sugar cannot get into the cells, it stays in the blood. The kidneys filter some of the sugar from the blood and remove it from the body through urine. Because the cells cannot receive sugar for energy, the body begins to break down fat and muscle for energy. When this happens, ketones, or fatty acids, are produced and enter the bloodstream, causing the chemical imbalance (metabolic acidosis) called diabetic ketoacidosis. Ketoacidosis can be caused by not getting enough insulin, having a severe infection or other illness, becoming severely dehydrated, or some combination of these things. It can occur in people who have little or no insulin in their bodies (mostly people with type 1 diabetes but it can happen with type 2 diabetes, especially children) when their blood sugar levels are high. Your blood sugar may be quite high before you notice symptoms, which include: Flushed, hot, dry skin. Feeling thirsty and urinating a lot. Drowsiness or difficulty waking up. Young children may lack interest in their normal activities. Rapid, deep breathing. A strong, fruity breath odor. Loss of appetite, belly pain, and vomiting. Confusion. Laboratory tests, including blood and urine tests, are used to confirm a diagnosis of diabetic ketoacidosis. Tests for ketones are available for home use. Keep some test strips nearby in case your blood sugar level becomes high. When ketoacidosis is severe, it must be treated in the hospital, often in an intensive care unit. Treatment involves giving insulin and fluids through your vein and closely watching certain chemicals in your blood (electrolyt Continue reading >>
Introduction Diabetic ketoacidosis (DKA) is a dangerous complication of diabetes caused by a lack of insulin in the body. Diabetic ketoacidosis occurs when the body is unable to use blood sugar (glucose) because there isn't enough insulin. Instead, it breaks down fat as an alternative source of fuel. This causes a build-up of a by-product called ketones. Most cases of diabetic ketoacidosis occur in people with type 1 diabetes, although it can also be a complication of type 2 diabetes. Symptoms of diabetic ketoacidosis include: passing large amounts of urine feeling very thirsty vomiting abdominal pain Seek immediate medical assistance if you have any of these symptoms and your blood sugar levels are high. Read more about the symptoms of diabetic ketoacidosis. Who is affected by diabetic ketoacidosis? Diabetic ketoacidosis is a relatively common complication in people with diabetes, particularly children and younger adults who have type 1 diabetes. Younger children under four years of age are thought to be most at risk. In about 1 in 4 cases, diabetic ketoacidosis develops in people who were previously unaware they had type 1 diabetes. Diabetic ketoacidosis accounts for around half of all diabetes-related hospital admissions in people with type 1 diabetes. Diabetic ketoacidosis triggers These include: infections and other illnesses not keeping up with recommended insulin injections Read more about potential causes of diabetic ketoacidosis. Diagnosing diabetic ketoacidosis This is a relatively straightforward process. Blood tests can be used to check your glucose levels and any chemical imbalances, such as low levels of potassium. Urine tests can be used to estimate the number of ketones in your body. Blood and urine tests can also be used to check for an underlying infec Continue reading >>
Professor of Pediatric Endocrinology University of Khartoum, Sudan Introduction DKA is a serious acute complications of Diabetes Mellitus. It carries significant risk of death and/or morbidity especially with delayed treatment. The prognosis of DKA is worse in the extremes of age, with a mortality rates of 5-10%. With the new advances of therapy, DKA mortality decreases to > 2%. Before discovery and use of Insulin (1922) the mortality was 100%. Epidemiology DKA is reported in 2-5% of known type 1 diabetic patients in industrialized countries, while it occurs in 35-40% of such patients in Africa. DKA at the time of first diagnosis of diabetes mellitus is reported in only 2-3% in western Europe, but is seen in 95% of diabetic children in Sudan. Similar results were reported from other African countries . Consequences The latter observation is annoying because it implies the following: The late diagnosis of type 1 diabetes in many developing countries particularly in Africa. The late presentation of DKA, which is associated with risk of morbidity & mortality Death of young children with DKA undiagnosed or wrongly diagnosed as malaria or meningitis. Pathophysiology Secondary to insulin deficiency, and the action of counter-regulatory hormones, blood glucose increases leading to hyperglycemia and glucosuria. Glucosuria causes an osmotic diuresis, leading to water & Na loss. In the absence of insulin activity the body fails to utilize glucose as fuel and uses fats instead. This leads to ketosis. Pathophysiology/2 The excess of ketone bodies will cause metabolic acidosis, the later is also aggravated by Lactic acidosis caused by dehydration & poor tissue perfusion. Vomiting due to an ileus, plus increased insensible water losses due to tachypnea will worsen the state of dehydr Continue reading >>
Editorial Review Diabetic Ketoacidosis: Role Of The Kidney In The Acid-base Homeostasis Re-evaluated
The development of diabetic ketoacidosis (DKA) involves a series of closely interrelated derangements of intermediary metabolism and of body fluid volume and composition whose fundamental nature has not been completely unraveled [1–8]. The composite clinical picture in full-blown DKA on admission includes hyperglycemia with hyperosmolality, metabolic acidosis due to the accumulation of ketoacids, extracellular and intracellular fluid (ECF and ICF, respectively) volume depletion, and varying degrees of electrolyte deficiency, particularly of potassium and phosphate [9–11]. Since proper correction of the alterations in volume status, acid-base, and electrolyte composition is critical for survival, a clear understanding of the pathogenesis of these derangements is essential for the adequate management of DKA. The present review will focus on the role of the kidney in the pathogenesis of the different patterns of electrolyte and acid-base composition observed on admission for and during recovery from DKA. Special emphasis will be placed on the role of the kidney in the defense of acid-base homeostasis during the recovery phase. Other aspects of the alterations that develop in DKA have been reviewed in detail elsewhere [12–14]. Continue reading >>
Diabetes And Kidney Damage (nephropathy)
Over time, high blood sugars can cause damage to the kidneys. This is called kidney disease, kidney damage or nephropathy. Your kidneys contain special filters that help clean your blood, remove waste, and control your fluid balance. These filters are called nephrons. Over time, high blood sugar can damage them and cause them to leak protein, called albumin, into your urine. You may experience no symptoms if the damage is minor. However, the extra protein (albumin) can show up on routine blood work conducted by your doctor. Untreated, damage to your kidneys can grow until kidney dialysis or a kidney transplant are necessary. Long-term studies show that achieving your HbA1c targets dramatically lowers your risk for kidney disease.1 The National Institute of Health’s (NIH) Medline Plus center states that kidney damage is more likely to occur if you: Have uncontrolled blood sugar Have high blood pressure Have type 1 diabetes that began before you were 20 years old Have family members who also have diabetes and kidney problems Smoke Are African American, Mexican American, or Native American See your healthcare provider yearly to get tested for any early signs of kidney damage or signs that there could soon be damage to the kidneys. There are different tests available that your healthcare provider should use. Urine albumin test (microalbuminuria): This involves a urine sample which is tested for the presence of a protein called albumin which may leak into the urine from the kidneys. This may indicate the presence of kidney damage. Blood urea nitrogen test (BUN): This involves a sample of blood from a vein and checks kidney function. Serum creatinine: This can be done by urine or blood sample and measures creatinine which should normally be removed by your kidneys so testin Continue reading >>
Diabetes And Kidney Failure (stage 5)
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 damage to the very small blood vessels in your kidneys. Over time, this can lead to kidney disease and kidney failure. What is kidney failure? Healthy kidneys do many important jobs. They filter your blood, keep fluids in balance, and make hormones that help your body control blood pressure, have healthy bones, and make red blood cells. If you have kidney failure, it means your kidneys have stopped working well enough to do these important jobs and keep you alive. As a result: Harmful wastes build up in your body Your blood pressure may rise Your body may hold too much fluid Your body cannot make enough red blood cells When this happens, you need treatment to replace the work of your failed kidneys. There is no cure for kidney failure. A person with kidney failure needs treatment to live. Three types of treatment can be used if your kidneys have failed: Hemodialysis Peritoneal dialysis Kidney transplantation Your healthcare team will discuss these different treatments with you and answer all your questions. They will help you choose the best treatment for you, based on your general health, lifestyle, and treatment preference. Your decision does not need to be final. Many people have used each one of these treatments at different times in their lifetime. If I have kidney failure and diabetes, what will my treatment involve? A kidney doctor (called a nephrologist) will plan your treatment with you, your family, and your dietitian. In addition to dialysis or a transplant, you will need to: Keep your blood sugar under control. This is usually done with d Continue reading >>
How Does Ketoacidosis Affect The Human Brain?
Diabetic Ketoacidosis (DKA) is the body’s emergency reaction to glucose starvation in the absence of insulin. It is a disastrous reaction — in general, it makes things worse rather than better, and starts a vicious cycle of blood acidity, rising blood glucose, dehydration, and blood hyperosmolality (high concentration of dissolved stuff) that can be hard to break. One of the hardest-hit organs in DKA is the brain, due to the dehydration and acidic blood entering that sensitive organ. Severe DKA may lead to brain swelling (edema) which is life-threatening. But recent studies have shown that even a short, apparently fully-recovered stint of DKA leads to measurable brain injury. Diabetic Ketoacidosis (DKA) is a life–threatening consequence of diabetes. DKA occurs when there is a lack of insulin in the body causing hyperglycemia. As a result of the inability of glucose to enter the cells, the body must find other means to obtain energy. As such, fat breakdown occurs resulting in the accumulation of fatty acids. The fatty acids are metabolized to ketones that cause the blood to become acidotic (pH less than7.3). Because glucose remains in the blood, there is an increase in thirst and drinking to eliminate the solute load of glucose, which also results in increased urination (polyuria and polydipsia). Thus, the combination of increased serum acidity, weight loss, polyuria, and polydipsia may lead to extreme dehydration, coma, or brain damage. Without a doubt, the most severe acute complication of DKA is cerebral edema. Many cases of new onset type 1 diabetes present DKA (15-70 percent depending on age and geographic region, according to multiple studies), hence the importance of an early diagnosis of diabetes in order to avoid potential consequences. Much research is be Continue reading >>
