9 Signs Your UTI is Getting Worse

The short answer

When UTIs progress, they can lead to worse symptoms such as high fever, chills, nausea, vomiting, and mental changes. In extreme cases, they can cause low blood pressure, kidney failure, and severe pelvic or loin pain.

Key Facts

  • UTIs are common bacterial infections that affect different parts of the urinary system, including the bladder, urethra, ureters, and kidneys.
  • These infections can cause a range of symptoms, from mild discomfort to severe pain. Left untreated, they can lead to serious health complications, including kidney damage.
  • Early detection and appropriate treatment can prevent UTIs from worsening.
  • Contact your healthcare provider immediately if you experience any of these worsening symptoms. It’s always safer to seek professional help early rather than risk complications (reference).

Signs Your UTI is Getting Worse:

1. Fever

Fever is a common symptom of an infection. The body raises its temperature as a defense mechanism to kill off bacteria or viruses. When a UTI worsens, the fever can rise above 100.4 F (38 C), indicating a systemic infection (reference). Fever can also cause:

  • Sweating
  • Shivering
  • Headache
  • Muscle aches
  • Loss of appetite (reference).

2. Chills or Rigors

Chills or rigors – an intense, often uncontrollable shivering – usually accompany a high fever (reference). This is a natural response to fight off the infection, but it may indicate that the UTI is spreading to your kidneys. Symptoms of rigors include:

  • Intense shivering
  • Coldness
  • Paleness (reference).

3. Pus in Urine

If your urine appears cloudy or has a strong, unpleasant odor, it could contain pus, a thick, opaque fluid produced in response to infection. This could indicate a severe UTI and should be addressed immediately. Symptoms include:

  • Cloudy urine
  • Strong-smelling urine
  • Thick or lumpy discharge in urine (reference).

4. Flank or Loin Pain

When a UTI ascends to your kidneys, it can cause pain in the side, back, or lower abdomen. This is referred to as flank or loin pain (reference). If you experience any of these symptoms, seek immediate medical attention:

  • Severe pain in the lower back or sides
  • Pain that spreads to the lower abdomen or groin
  • Pain comes in waves and fluctuates in intensity (reference).

5. Pelvic or Perineal Pain (Especially in Men)

Pelvic or perineal pain – discomfort in the area between the anus and the genitals – is a common symptom of a worsening UTI, especially in men (reference). This could indicate prostatitis, inflammation, or infection of the prostate gland. Symptoms may include:

  • Pain or discomfort in the groin area
  • Difficulty urinating

6. Nausea and Vomiting

As the infection spreads and becomes more serious, it may cause feelings of nausea or even bouts of vomiting. These symptoms are your body’s response to the infection and can occur when the UTI spreads to the kidneys. This can also cause:

  • Loss of appetite
  • Abdominal discomfort or pain
  • Dizziness.

7. Deterioration of Mental State (Especially in the Elderly)

In older adults, a sudden change in mental states, such as confusion or delirium, could indicate a severe UTI. In some cases, these changes can be the only sign of a UTI in the elderly (reference). This is often accompanied by:

  • Delirium or severe confusion
  • Hallucinations
  • Agitation
  • Sudden mood changes.

8. Low Blood Pressure (Shock)

If the infection becomes severe, it can lead to sepsis, a dangerous condition that can cause low blood pressure or shock. This is a medical emergency and should be treated immediately. Symptoms can include:

  • Feeling lightheaded or faint
  • Rapid heartbeat
  • Loss of consciousness.

9. Kidney Failure

In severe cases, a UTI can lead to kidney failure, a serious condition that requires immediate medical attention. Symptoms may include:

  • Shortness of breath
  • Swelling in the legs, ankles, or feet
  • Fatigue or weakness
  • Little or no urine output
  • Persistent nausea
  • Persistent hiccups (reference).

While these signs can indicate a worsening UTI, it’s crucial to remember that only a healthcare provider can accurately diagnose and treat your condition. If you’re experiencing any of these symptoms, don’t hesitate to seek medical attention. Early intervention can significantly impact your recovery speed and overall health outcome.

FAQs about complicated UTI signs.

What are the symptoms of an extreme UTI?

In cases where a UTI has become severe or complicated, various worrisome symptoms may emerge. High temperatures over 100.4 F (38 C), chills, or rigors might indicate the worsening situation. Additionally, urine with pus signifies the escalating condition.

Serious symptoms can include intense pain in the flank or loin region, pointing to kidney involvement, and experiences of nausea or vomiting. A shift in mental status, especially noted in seniors, can also be a red flag for severe UTI.

A potentially life-threatening condition called sepsis may cause low blood pressure or shock. Kidney failure symptoms like breathlessness, minimal or no urine output, or lasting hiccups can all be signs of an extremely progressed UTI.

How do I know if a UTI has spread to my kidneys?

A kidney infection, or pyelonephritis, which happens when a UTI spreads to the kidneys, manifests through a variety of symptoms.

Common signs include pain or discomfort in the side, back, or lower abdomen, also known as flank or loin pain. Other symptoms can be a high fever, chills, feelings of nausea, vomiting, and overall discomfort. The presence of cloudy, foul-smelling urine, or urine containing pus or blood, is also an indicator. Immediate medical help is necessary if a kidney infection is suspected.

How long until a UTI gets serious?

The timeframe within which a UTI escalates to a serious level varies, depending largely on factors like the individual’s health status and the infecting bacteria’s type. Some UTIs could develop into a severe state in just a few days, while others might take a week or more to show serious symptoms.

Regardless of the timeline, it’s crucial to seek medical care as soon as one identifies UTI symptoms to prevent further infection spread and complications.

What does a serious UTI look like?

A UTI that has progressed to a serious stage will typically exhibit symptoms of greater severity than a regular UTI. These symptoms can include a high fever, intense chills, severe lower back or side pain, nausea, and vomiting.

Elderly individuals may experience changes in mental state. The urine may appear cloudy, have a strong odor, and could contain pus. If the infection becomes critical, it can lead to low blood pressure or even shock. In the gravest cases, symptoms of kidney failure may arise. Any of these symptoms warrant immediate medical attention.
