Urinary health concerns are quite common, particularly among women; however, anybody can suffer from these issues. The two most frequent concerns can be Urinary Tract Infection (UTI) and Kidney Infection. The symptoms are generally the same, including burning sensations when urinating, frequent urination or abdominal pain in the lower abdomen.
In this blog, we will discuss the major differences between UTI and kidney infections, including the symptoms, the risks, causes, treatments, and when it is appropriate to consult a physician. In the end, you will be able to recognize each health issue and the best time to seek medical attention to safeguard your health.
What is a UTI?
A UTI is an infection that can happen anywhere in the urinary system, namely the urethra, bladder, ureters, or kidneys. Most commonly, it will affect the bladder.
Symptoms of a UTI:
- An itch or burning feeling occurs when you urinate
- Urination is a frequent requirement even when the bladder is almost empty
- Ureter that smells cloudy or unpleasant
- The pain or pressure can be felt in the stomach area
- Mild pelvic pain
UTIs typically result from a bacterium such as E. coli invading the urinary tract. It is typically due to poor hygiene, dehydration, or sexual activity.
What is a Kidney Infection?
This kidney disease is caused by a germ that travels through the bladder and eventually gets into the kidneys, either in one or both. While it’s not a more serious problem than a typical UTI, if it is not treated, it could cause harm to the kidneys.
Typical Symptoms of a Kidney Infection:
- Extreme fever and chills
- Nausea and vomiting
- Back or side pain severe (flank pain)
- Body pain and fatigue
- Burning while urinating (similar to UTI)
- Pus or blood in the urine
If not treated, kidney infections could cause irreparable damage to the kidneys or blood poisoning, which is a deadly infection
