6. METALIC TASTE IN THE MOUTH
The high amount of waste in the organism accompanied with improper kidney’s function leads to bed breath and changes in the flavor of the food.
7. LACK OF CONCENTRATION AND DIZZINESS
The low amount of oxygen in the brain could not just point out anemia but also an improper function of the kidneys. This would disturb the concentration and focus, make you dizzy and forgetful.
There is no more convincing symptom than this one. The pain in the upper back alarms that there is a certain problem with the kidneys. Also it not only an alarm for a kidney failure but also for kidney infection or kidney stones.
Bear in mind not to ignore these symptoms but you should concentrate on the intake of food rich in antioxidants, vitamins and minerals.
