Kidney health, keep your kidney healthy
Kidneys reach maximum function at approximately age 10 and ultimately weigh about five ounces each. Despite their small size, they receive about 25 percent of the heart output and cleanse the entire volume of blood many times per day.
How well the kidney functions is expressed as glomerular filtration rate (GFR.) Normal GFR is 90–100 percent. In addition to cleaning blood, kidneys correct salt and water imbalance. They release and regulate hormones important in bone health and in the manufacture of red blood cells.
They regulate blood pressure and important chemicals in the blood including sodium, potassium, calcium, phosphate, magnesium and acid. The kidneys also remove toxins and drugs from the body.
The most common causes of kidney disease are diabetes and high blood pressure. There are also inherited kidney diseases such as polycystic kidney disease and Alport’s syndrome. Chronic kidney disease (CKD)
Early & late signs of kidney disease
Signs of early kidney damage can develop in more than half the people with diabetes. If left untreated, this could lead to more damage or kidney failure.
During its early course, diabetic nephropathy often has no symptoms. Symptoms can take 5 to 10 years to appear after the kidney damage begins.
You could be in a process of serious kidney damage without being aware of it. There are usually no specific symptoms of kidney disease until the damage is severe. However, if you have diabetes, you should be tested once a year to see if diabetes has affected your kidneys. Your doctor can arrange a urine test for protein (a random urine test for albumin to creatinine ratio and microalbuminuria), and a blood test to check how well your kidneys are functioning (the serum creatinine).
As the kidney function worsens, symptoms may include:
* Swelling of the hands, feet, and face
* Trouble sleeping or concentrating
* Poor appetite
* Nausea and vomiting
* Itching (end-stage kidney disease) and extremely dry skin
* Drowsiness (end-stage kidney disease)
* Abnormalities in the heart’s regular rhythm, because of increased potassium in the blood
* Muscle twitching
As kidney damage progresses, your kidneys cannot remove the waste from your blood. The waste then builds up in your body and can reach poisonous levels, a condition known as uremia. People with uremia are often confused or comatose.
Worsening of kidney disease may be slowed, stopped or even reversed if caught very early. It is very important to slow worsening of kidney as the advanced stage of the disease is kidney failure, when the kidney -cannot do its job of filtering harmful wastes from the blood.
Kidney disease can progress to kidney failure more quickly among those who have diabetes. The best chance to stop kidney disease from progressing is to recognize it early and start with a treatment course that can slow or stop the decline in kidney function.
Eating tips for healthy Kidney
Choose and prepare foods with less salt and sodium. Why? To help control your blood pressure. Your diet should contain less than 2,300 milligrams of sodium each day
■ Use spices, herbs, and sodium-free seasonings in place of salt.
