Understanding the Causes of Kidney Infections

The kidneys play a vital role in cleansing the blood by removing waste and excess fluids to produce urine. Usually, one healthy kidney suffices for maintaining body functions since each kidney contains enough tissue to perform these tasks. However, if kidney tissue becomes damaged or infected, serious health issues may arise. Bacterial infections, particularly from E. coli, are a common culprit in harming the kidneys. When bacteria travel from other parts of the body and reach the kidneys, they can lead to dangerous infections that require prompt attention.

Kidney infections are categorized based on their occurrence.

Acute - A sudden inflammation affecting the renal pelvis and kidneys, often indicated by blood or pus in the urine.

Chronic - Characterized by repeated infections that can lead to abscess formation and permanent damage, accompanied by symptoms like fever, nausea, and foul-smelling urine.

Common Causes of Kidney Infections

Infections reach the kidneys through several pathways:

Weak immune defenses allow bacteria from the skin or other areas to enter the bloodstream and infect the kidneys.

Poor hygiene practices can introduce bacteria from the anal or genital areas, especially in women due to their shorter urethra, increasing infection risk.

Incomplete bladder emptying caused by injuries or illness creates an environment where bacteria can multiply rapidly in the urinary tract.

Other factors like urinary tract blockages or external urinary catheter use can also contribute to kidney infections.
