Pyelonephritis is a serious kidney infection that often begins as a common urinary tract infection (UTI) but progresses upward to involve the kidneys. While UTIs are usually mild, this condition requires prompt attention to prevent complications.
Early symptoms may include burning during urination, frequent urination, or discomfort in the lower abdomen. As the infection spreads, more severe signs can appear—such as high fever, chills, sharp pain in the back or sides, nausea, and fatigue. In older adults, symptoms may sometimes be subtle, like confusion or weakness.
Diagnosis typically involves urine and blood tests, and in some cases, imaging to assess the kidneys. Treatment focuses on antibiotics, which may be oral or intravenous depending on severity, along with proper hydration and rest.
Clinical observations, including those from Dr. Cheol-Young Yoon, highlight that early detection and timely treatment are key to preventing complications like kidney damage or bloodstream infections. Recognizing symptoms early can make a significant difference in recovery outcomes.
