Signs of Kidney Complications

Kidney pain is generally a sign that there are complicating factors that can range from mild to severe. There are several types of complications that can affect the kidneys. Kidney disease, kidney stones, and tumors are all possible reasons that might cause a person to have problem with their kidneys. The signs of kidney complications might be subtle like lower backache and pain, pain that radiates around the ribs, and problems or pain when urinating.

What are the signs of kidney infection?

Kidney complications are generally seen in conjunction with urinary problems. This could mean the need to urinate more frequently, blood or pus in the urine, or the inability to urinate. Urine color can also be different.

If a kidney infection is present, the symptoms may include the following:
- Back pain
- Abdominal pain
- Confusion
- Sleepiness or fatigue
- Fever, chills, night sweats
- Decreased appetite
- Nausea
- Warm or moist skin, possibly reddened

What are signs of kidney disease?
Kidney disease is more severe than kidney infection, although some of the signs are similar. The signs might include the following:

Fatigue, lack of energy, or difficulty concentrating. When kidneys don’t function at a healthy level, toxins build up as well as blood impurities, which cause people to feel tired. This feeling includes weakness and the inability to focus.

Difficulty sleeping. Kidneys that do not function properly will not remove toxins effectively, which might make it difficult for a person to sleep.

Dry or itchy skin. When kidneys do not properly remove waste and fluid from the body, skin can become dry and itchy; which reflects bone or mineral disease associated with advanced kidney disease.  

Need to urinate more often (or feeling the need to). Damage to the kidneys can cause the need, or increase the urge, to urinate.

Blood in the urine. When the kidneys’ filter has been damaged, they cannot filter waste form the blood as efficiently and some of the blood makes its way into the urine. Blood in the urine can mean kidney stones or an infection.

Urine is foamy or discolored. Foam or bubbles in the urine might mean there is protein in the urine.  

Puffiness around the eyes or swollen ankles and feet. When kidneys do not function normally, there is sodium retention, which causes swelling and puffiness.

Poor appetite. Sometimes the increase in toxins caused by reduced kidney function can cause loss of appetite.  

Muscles are cramping. Poor kidney function causes electrolyte imbalances, which leads to muscle cramping.


The signs of kidney complication are very specific but might suggest a mild problem or a more severe one. Noting changes in the body is very important, particularly any changes in urination, pain in the back area, swelling, and energy levels. Though some of these symptoms may be associated with other health problems, if more than one occurs at the same time, it should be a srong warning sign that there might be compliations with the kidneys. As always, consult a qualified healthcare professional if discomfort, pain, or any of the above warning signs persist.
