what causes high creatinine in kidneys?

Generally, a high serum creatinine level means that your kidneys aren't working well. Your creatinine level may temporarily increase if you're dehydrated, have a low blood volume, eat a large amount of meat or take certain medications. The dietary supplement creatine can have the same effect.

Although the mechanisms are unclear, early chronic renal failure Kidney: chronic kidney disease (CKD) leads to increased levels of parathyroid hormone (PTH). This causes enhanced excretion of phosphate by the kidneys. However, by late chronic renal failure this mechanism is inadequate leading to hyperphosphatemia.

However, when kidneys do not work well, they may not be able to remove enough potassium. This means that potassium can build up in your blood to harmful levels. Eat a diet high in potassium. Eating too much food that is high in potassium can also cause hyperkalemia, especially in people with advanced kidney disease.

Hypocalcemia in chronic renal failure is due to two primary causes - increased serum phosphorus and decreased renal production of 1,25 (OH)2 vitamin D. The former causes hypocalcemia by complexing with serum calcium and depositing it into bone and other tissues.

Kidney disease is the most common cause of hyperkalemia. Your kidneys help control the balance of potassium in your body. If they don't work well, they can't filter extra potassium from the blood or remove it from the body. A hormone called aldosterone tells the kidneys when to remove potassium.

Creatinine clearance ( CrCl ) is an estimate of Glomerular Filtration Rate ( GFR ); however, CrCl is slightly higher than true GFR because creatinine is secreted by the proximal tubule (in addition to being filtered by the glomerulus).

Causes. Most of the time, a high uric acid level occurs when your kidneys don't eliminate uric acid efficiently. Things that may cause this slow-down in the removal of uric acid include rich foods, being overweight, having diabetes, taking certain diuretics (sometimes called water pills) and drinking too much alcohol.

Drinking more water could lower the serum creatinine level, but does not change kidney function. Forcing excessive water intake is not a good idea.

Creatinine is removed from the blood chiefly by the kidneys, primarily by glomerular filtration, but also by proximal tubular secretion. Little or no tubular reabsorption of creatinine occurs. If the filtration in the kidney is deficient, blood creatinine concentrations rise.

Potential increased health risks. Excessive calcium supplement intake has been associated with a higher risk of kidney and possibly an increased risk of cardiovascular disease and aggressive prostate cancer.

Chronic Kidney Failure It's most commonly caused by diabetes or high blood pressure. Your kidneys slowly stop working the right way. That makes waste fluids build up in your body, which can damage nerves (uremic neuropathy), including in your feet, and cause a burning feeling.

When your kidneys are not working well, too much phosphorus can build up in your blood. This is called hyperphosphatemia. Your kidneys also help your body use vitamin D. When your kidneys are not working, your body may not be able to use vitamin D like it should. This can also cause your bones to get weak.

Kidney failure Conditions like high blood pressure (hypertension) or diabetes can lead to kidney failure. When your kidneys aren't functioning correctly, fluid and waste products may accumulate in your body, leading to nerve damage. Tingling due to kidney failure often occurs in the legs or feet.

A high BUN value can mean kidney injury or disease is present. Kidney damage can be caused by diabetes or high blood pressure that directly affects the kidneys. High BUN levels can also be caused by low blood flow to the kidneys caused by dehydration or heart failure.

When kidneys fail, urea that builds up in the blood can cause diabetes, concludes a study published today in the Journal of Clinical Investigation. "We identified molecular mechanisms that may be responsible for increased blood glucose levels in patients with non-diabetic chronic kidney disease.

High BUN-to-creatinine ratios occur with sudden (acute) kidney problems, which may be caused by shock or severe dehydration. A very high BUN-to-creatinine ratio may be caused by bleeding in the digestive tract or respiratory tract.
