UTIs are painful primarily because the infection causes irritation and inflammation in the urinary tract. According to provided information, when you have a UTI, the lining of the bladder and urethra become red and irritated. This irritation is the main culprit behind the discomfort.
Here's a more detailed breakdown:
- Inflammation: The presence of bacteria triggers an inflammatory response in the urinary tract. This inflammation leads to swelling and increased sensitivity of the tissues.
- Irritation of the Lining: The bladder and urethra's inner lining become raw and tender due to the infection.
- Increased Urgency and Frequency: The irritation stimulates the bladder, creating a frequent and urgent need to urinate, even when the bladder is not full.
- Pain During Urination (Dysuria): As urine passes over the inflamed and irritated lining of the urethra, it causes a burning sensation and pain. You may feel some burning as your urine comes out.
- Pelvic Pain: The inflammation can extend to the pelvic area, resulting in general discomfort and pain. This can cause pain in your stomach and pelvic area.
In summary, the combination of inflammation, irritation, and increased sensitivity of the urinary tract lining is what makes UTIs so painful. You may try to urinate but only produce a few drops.
