Diet To lower High Creatinine levels
Creatinine is a blood test that is ordered to assess kidney function. Using this test, along with other factors such as age, gender and weight, can help physicians calculate the estimated glomerular filtration rate (eGFR), which is a measure of kidney damage.
There is no one particular kidney diet for patients with elevated creatinine. Individual dietary recommendations are based upon the patient's lab results, blood pressure, symptoms and other metrics. Making dietary changes has no preventative value if the change is not merited. Since patients with moderate kidney disease often have to heed to a restricted diet eventually, there is no sense in imposing restrictions that serve no purpose.
Your body uses protein to build and repair tissues and muscles and to fight off infection. When protein is broken down, like any other food, it produces certain waste products. One of these is urea, which damaged kidneys have trouble filtering out of the bloodstream. Most renal diets require you to monitor and limit your protein intake. Your doctor, dietitian or nutritionist will tell you how much and what types of protein you can consume. You will probably be allowed certain amounts of complete proteins from animal sources and certain amounts of incomplete proteins from plant sources .
High potassium levels can kill kidney patients, which is why this tests for this mineral are included in routine laboratory work. High levels cause nerves to fire erratically, which in turn causes heart arrhythmias and tachycardia. However, you can control high potassium levels by avoiding high potassium foods. This requires eliminating many otherwise healthy foods from the diet, such as broccoli, tomatoes, potatoes, legumes, acorn squash and oranges. Substituting lower potassium foods such as peppers, mushrooms, onions, white rice and pasta is an effective strategy in meal planning if potassium restriction is necessary.
When kidney disease or high blood pressure is suspected, the first dietary change is often to reduce sodium in the diet. Fresh foods over packaged, convenience foods are recommended. Canned foods are particularly high sources of sodium in the American diet. When eating out, those trying to lower their sodium intake should avoid fast food restaurants and ask that foods be prepared without salt.
Phosphorus levels often become elevated as the kidneys are unable to regulate phosphorus content in the blood. One of the first symptoms of high phosphorus levels is uncontrollable itching. These high levels are is dangerous because phosphorus in the blood leaches calcium from the bones. Doctors use the term renal osteodystrophy to describe the bone damage that results. Patients with high phosphorus levels can prevent this from occurring by eating a low-phosphorous diet and taking drugs called phosphorus binders when they eat. High phosphorus foods to avoid include milk and milk products, chocolate, beer, organ meats, dried beans and other legumes.
