Blood in Urine Before Menstruation: Causes and Concerns

Hematuria before menstruation?

Hello, doctor.
My menstrual period is expected to occur within the next 2-3 days, and I have been experiencing noticeable premenstrual symptoms and discomfort for about a week.
I would like to ask about my current situation: in addition to feeling dull pain in my lower abdomen (with occasional sharp pains), I sometimes notice blood in my urine after urination (the blood seems to be predominant).
When I wipe with tissue, it appears that the blood is not coming from the vagina but rather closer to the anal area or the urethra.
It feels like the blood is coming from my urine rather than flowing out, as there is no bright red blood on my pad.
Is this just a symptom related to my menstrual cycle, or is my body signaling a potential issue?

Answer: First, it is important to determine the source of the bleeding, whether it is from the uterus or the bladder.
This requires a medical examination at a hospital.

More Info

When it comes to experiencing blood in urine (hematuria) just before menstruation, it is essential to understand the potential causes and implications. While some women may experience various symptoms leading up to their menstrual cycle, the presence of blood in urine can indicate a range of issues that may require medical attention.

Firstly, it is crucial to differentiate the source of the bleeding. In your case, you mentioned that the blood seems to be coming from the urinary tract rather than the vaginal area. This distinction is vital because it can help narrow down the potential causes. Blood in urine can arise from several conditions, including urinary tract infections (UTIs), kidney stones, or even more serious conditions like bladder or kidney issues.

In the context of your symptoms, the following points should be considered:
1. Urinary Tract Infection (UTI): UTIs are common and can cause symptoms such as abdominal pain, frequent urination, and hematuria. The inflammation and irritation of the urinary tract can lead to bleeding, especially if the infection is severe.

2. Kidney Stones: These can cause significant pain and bleeding as they pass through the urinary tract. If you have a history of kidney stones or experience severe pain, this could be a possibility.

3. Menstrual Cycle Influence: Hormonal changes leading up to menstruation can sometimes cause increased sensitivity or inflammation in the pelvic region, which might contribute to bleeding. However, this is less common and usually not the primary cause of hematuria.

4. Other Conditions: Conditions such as interstitial cystitis, endometriosis, or even trauma to the pelvic area can also lead to blood in urine.
Given that you are experiencing this symptom alongside abdominal pain, it is advisable to seek medical evaluation. A healthcare provider can perform a urinalysis to check for signs of infection, blood, or other abnormalities. They may also recommend imaging studies, such as an ultrasound, to assess for kidney stones or other structural issues.

In summary, while some symptoms may be related to your menstrual cycle, the presence of blood in urine is not something to overlook. It is essential to consult with a healthcare professional to determine the underlying cause and receive appropriate treatment. Early intervention can prevent complications and ensure that any serious conditions are addressed promptly.
