The kidneys are two bean-shaped organs located on the back side under the rib cage. Their main function is to filter the fluids that passed through it from the gut, and remove the excretory waste products, thus converting the wastes products into fluids that could be passed out, while it returns the filtered fluid back into the blood circulation.

Kidney disease symptoms start manifesting when the kidney’s excretory roles and function is depreciating.

Kidney infections (such as pyelonephritis and glomerulonephritis) are subset of kidney diseases which encompasses a whole lots of damages which may accrue to the kidney, some of which are kidney failure and kidney stones.

The first sign of kidney disease is that glomerular filteration rate (GFR) drops. This is a measure of how fast or how efficient the kidney can remove the waste products from the fluids that passed through it.

Kidney diseases may develop as a result of infections, or overload of waste products in the body which has gone beyond the body’s natural ability to get rid of them.

Kidney infections may arise from urinary tract infection which comes in through the upper urinary tract commonly caused by micro organisms such as Escherichia coli, Candida albican etc.

Let’s looks at the signs of kidney infection and kidney infection symptoms.

The probable signs that could be noticed during the evaluation of kidney problems or routine clinical examinations may fall into one of the following:

  • White blood cells in the urine.
  • Pus cells from bacterial activities in the urine, this may also change the color of the urine from the usual light color to a darker color.

Symptoms of kidney infection start manifesting as soon as the infection has been established either in the glomeruli or in the nephrons of the kidney. It could be as early as few hours or days.

One of the most noticeable symptoms of kidney infection is frequent cloudy and occasionally foamy urine.

Other kidney infection symptoms

  • Frequent urge to urinate.
  • Abdominal pain.
  • Frequent burning sensation when urinating.
  • offensive or pungent urine odor.
  • Flank pain.
  • Diarrhea
  • Nausea

The following lists below are the signs of kidney disease as obtained from diagnostic reports:

1) Increased serum creatinine levels.

Serum creatinine is a protein formed as a metabolic waste product of muscular activities. It is a protein that measures the ability of the kidney to function at optimum capacity, when its level is above. Muscular men tends to have higher values, high protein diets may also elevate it, other than this, the normal creatinine level is 0.7 to 1.3 mg/dL for men and 0.6 to 1.1 mg/dL for women. If the value is  >1.5mg/dL, it is a sign that the kidney filteration efficiency is dropping.

2) Increased levels of BUN (Blood Urea Nitrogen)

When the level of urea nitrogen in your blood is beyond the normal levels. It is a sign of decreasing glomerular filteration rate of the kidney, only your doctor sees this from clinical examinations and diagnostic reports.

General symptoms of kidney disease

When you notice the following symptoms of kidney disease, it could be as a result of the elevated serum creatinine levels, blood urea nitrogen among other diagnostic tests:

  • Persistent fatigue: This could happen as a result of increased serum creatinine levels in the blood.
  • Drastic and frequent changes in urine output (volume-wise)
  • Loss of appetite.
  • Frequent lower back pain with feeling of tenderness on the kidney area.
  • Another example of kidney disease symptoms is urinary incontinence. This causes droplets of urine occasionally.
  • Sense of fullness around the bladder area.

Kidney infections symptoms can be treated with a course of antibiotics if reported early before it affects the kidneys’ excretory functions and damage the kidneys.
