How long does it take for a UTI to go away without antibiotics?
Why antibiotics sometimes don’t work
Kidney infections can lead to kidney damage and kidney scarring. Symptoms of a UTI usually improve within two to three days after starting antibiotic therapy. Many doctors prescribe an antibiotic for at least three days.
How long does a UTI last?
Most UTIs can be cured. Bladder infection symptoms most often go away within 24 to 48 hours after treatment begins. If you have a kidney infection, it may take 1 week or longer for symptoms to go away.
How do you tell if a UTI is going away?
Common UTI Symptoms
The telltale signs of a UTI include pain in the pelvis, abdomen and genitals as well as increased urge to urinate, painful urination or blood in the urine. Other possible symptoms include fatigue or fever, as well as discoloration or odor in the urine, trouble emptying the bladder or bladder spasms.
What happens if a UTI goes untreated for a week?
The main danger associated with untreated UTIs is that the infection may spread from the bladder to one or both kidneys. When bacteria attack the kidneys, they can cause damage that will permanently reduce kidney function. In people who already have kidney problems, this can raise the risk of kidney failure.
