Healthy Food Turmeric Protects the Kidney Against Renal Dysfunction

By Kyle J. Norton

Renal protection is strategies that protect the kidney against injury or damage. In other words, renal protection is a process that maintains the function of the kidneys.

Kidneys, a pair of the bean-shaped organ in the human body only filters out blood but also balances the body fluids by eliminating them and remove them through urinary secretion.

Depending on the severity of renal damage, patients may experience symptoms of decreased urine output, fluid retention, that lead to swelling in the legs, ankles or feet, fatigue, nausea, and physical weakness

In severe cases, patients may also have symptoms of shortness of breath, confusion, and irregular heartbeat.

The worse cases of kidney damage can lead to renal failure, a condition that induces wastes and toxins accumulated in the blood. In this stage, dialysis and kidney transplant are the only options.

Kidney damage can be classified into 4 different stages
* Stage 1 with normal or high GFR (GFR > 90 mL/min). In this stage of kidney patients are assymptomatic.

* Stage 2 Mild CKD (GFR = 60-89 mL/min), Patients in this stage also experience no symptoms.

*Stage 3A Moderate CKD (GFR = 45-59 mL/min) and 3B moderate CKD (GFR = 30-44 mL/min.

Most patients are assymptomatic. However, some patients may experience symptoms of mild swelling in the hands and feet, back pain and urinating more or less than normal.

* Stage 4 CKD (GFR = 15-30 mL/min). Most patients in this stage experience more severe symptoms of swelling in the hands and feet, back pain and urinating more or less than normal, accompanied by other health problem associated with weakened kidney function

* Stage 5 EndStage CKD (GFR <15 mL/min). Patients at this advanced stage are very close to renal failure or renal failure. Symptoms are getting worse.

Where eGFR is short for estimated glomerular filtration rate.

Turmeric is a perennial plant in the genus Curcuma, belonging to the family Zingiberaceae, native to tropical South Asia.

The herb has been used in traditional medicine as anti-oxidant, hypoglycemic, colorant, antiseptic, wound healing agent, and to treat flatulence, bloating, and appetite loss, ulcers, eczema, inflammations, etc.

In the urgency to find a potential compound with the kidney protective effect against the side effects of Cisplatin, researchers investigated the protective effect and mechanism of tetrahydrocurcumin on cisplatin-induced kidney damage.

The study included selected rats treated by Tetrahydrocurcumin orally every day at a dose of 80 mg/kg body weight for ten days, and a single dose of cisplatin was administered intraperitoneally (7.5 mg/kg body weight) in 0.9 % saline on day four.

According to the tested assays, Cisplatin-induced renal cell damage was significantly reduced by tetrahydrocurcumin treatment.

Tetrahydrocurcumin also suppressed the cisplatin-treated rat in inducing overexpression of the creatinine clearance levels, an indication of kidney dysfunction.

Proinflammatory protein associated with increased oxidative stress in the kidney caused by cancer medicine was also inhibited by tetrahydrocurcumin administration during the experiment.

After taking into account co and confounders, the researcher wrote, "collectively provide therapeutic evidence that tetrahydrocurcumin ameliorates renal damage by regulating inflammation and apoptosis".

In order to reveal more information about turmeric renal protective activity, researchers evaluated the intervening effects of Curcuma aromatica oil on renal interstitial fibrosis rats induced by unilateral ureteral obstruction.

The study included infected rats treated with Curcuma aromatica oil on 3, 7, 14, and 28 days.

According to the Nuclear magnetic resonance (NMR)-based metabonomics combined with clinical chemistry and histopathology examination, Curcuma aromatica oil demonstrated strong kidney protection by inhibiting some metabolic pathways associated with the onset of renal interstitial fibrosis, including lipids metabolism, glycolysis, and methylamine metabolism,

Taken altogether, turmeric processed abundantly bioactive compound curcumin may be considered supplements for the protection of kidneys, pending to the confirmation of the larger sample size and multicenter human study.

Intake of turmeric in the form of supplement should be taken with extreme care to prevent overdose acute liver toxicity.
