“Learn about kidney infection symptoms, causes, treatment options, and recovery tips to recognize early signs and seek timely medical care.”
A kidney infection also known as pyelonephritis is a urinary tract infection which affects either one or both the kidneys in the human body. This infection begins in the lower urinary tract such as urethra or bladder and travels upward through ureters towards the kidneys.
The work of kidneys is to filter the waste from the blood which helps in maintaining fluid and electrolyte balance in the human body. When left untreated, a kidney infection can lead to serious issues. In some cases, the bacterial enters the bloodstream and causes sepsis which is a life-threatening response to infection.
This infection can affect people of any age and is most commonly found in women. Timely diagnosis and right treatment are necessary as kidney infection needs antibiotics and cannot be cured on its own.
The early signs of kidney infection may either appear suddenly or develop gradually. Initially, people experience symptoms which are similar to those of bladder infection. The most common early symptoms include burning sensation, painful urinating, frequent or urgent need to urinate, cloudy or dark urine, strong smelling urine, blood in urine, painful in the lower abdomen and feeling weak.
When the infection reaches kidneys, the symptoms may develop and include fever, chills, pain in the back or side, nausea, vomiting, muscle ache and a general feeling of illness. If a patient experiences fever, pain or urinary symptoms then it indicates a kidney infection. Many adults have symptoms which are not that typical. In sever cases, there may be confusion or a noticeable change in the mental status.
If a patient experiences back pain, severe flank, vomiting, blood in the urine or difficulty in passing urine then immediate medical assessment might be needed. Pregnant women should immediately seek medical attention if the developed symptoms suggest a kidney infection.
The common kidney infections are caused by bacteria which enter through the urethra, multiply in bladder and travel upward towards the kidneys.
