You might feel pain when urinating during your period for a few reasons, but the menstruation itself doesn't typically irritate the bladder directly. One common cause, especially when the pain is significant, can be related to a condition called endometriosis.
Endometriosis and Bladder Pain
-
What is Endometriosis? Endometriosis is a condition where tissue similar to the lining of the uterus (endometrium) grows outside the uterus. This tissue can attach to other organs, including the bladder.
-
How it Affects Urination: If endometrial tissue implants on or near the bladder, it can cause inflammation and pain, especially during menstruation when these implants respond to hormonal changes just like the uterine lining. This can lead to painful urination (dysuria).
Other Potential Causes:
While endometriosis is a significant possible cause, especially if the pain is severe, other, more common issues can contribute:
-
Prostaglandins: Prostaglandins, hormones that trigger uterine contractions during menstruation, can sometimes also affect the bladder and bowel, potentially causing some discomfort.
-
Dehydration: Being dehydrated can concentrate urine, making it more irritating to the bladder, potentially leading to a burning sensation when urinating. Period hormones can contribute to dehydration.
-
Urinary Tract Infections (UTIs): Though not directly caused by menstruation, UTIs can cause painful urination. Symptoms often include a frequent urge to urinate, burning, and cloudy or bloody urine. It's important to consult a doctor if you suspect a UTI.
When to See a Doctor:
- If the pain is severe or persistent.
- If you have blood in your urine.
- If you experience frequent or urgent urination, even when your bladder isn't full.
- If you suspect you might have endometriosis based on other symptoms such as painful periods, pelvic pain, or pain during intercourse.
