Post-menstrual bleeding + urethritis?


Due to reduced water intake during the summer and a long-standing habit of holding in urine, I previously experienced a urinary tract infection.
This time, during my menstrual period, I also drank less water and felt a burning sensation when urinating.
After my period, I engaged in sexual intercourse with my boyfriend and noticed bleeding, which prompted us to stop immediately (the amount of bleeding that night was significant).
Afterwards, I experienced hematuria, a slight burning sensation when urinating, mild abdominal discomfort, and lower back pain.
I'm unsure what this issue might be.

Hello Miss Deng Deng: Your condition is likely just a simple acute urinary tract infection (UTI).
Hematuria associated with acute UTIs can sometimes temporarily resolve and then suddenly reappear, and it should not be specifically related to your sexual activity with your boyfriend.
I recommend that you drink plenty of water, avoid holding your urine, and engage in regular exercise.
Drinking more water before sexual activity and urinating promptly afterward may help reduce the likelihood of developing a urinary tract infection.

More Info


Post-menstrual bleeding and urinary tract infections (UTIs) can be concerning symptoms, especially when they occur together. Based on your description, it seems that you are experiencing a combination of symptoms that could be related to several underlying issues. Let's break down the potential causes and what you can do about them.


Possible Causes
1. Urinary Tract Infection (UTI): Given your history of UTI and the symptoms of burning sensation while urinating, blood in the urine, and abdominal discomfort, it is quite possible that you are experiencing a UTI. UTIs can occur when bacteria enter the urinary tract, often due to infrequent urination or dehydration, which you mentioned has been an issue for you in the past.

2. Post-Menstrual Bleeding: The bleeding you experienced after your menstrual period could be due to several factors. It might be related to hormonal changes, especially if your menstrual cycle has been irregular. Additionally, if you had sexual intercourse shortly after your period, it could have irritated the cervix or vaginal walls, leading to bleeding.

3. Cervical or Vaginal Irritation: Engaging in sexual activity shortly after menstruation can sometimes cause irritation, especially if there is any residual menstrual blood or if there was vigorous activity. This irritation can lead to bleeding and discomfort.

4. Pelvic Inflammatory Disease (PID): If the infection has spread beyond the urinary tract, it could lead to PID, which is an infection of the reproductive organs. Symptoms can include pelvic pain, fever, and abnormal bleeding.

5. Other Gynecological Issues: Conditions such as fibroids, polyps, or endometriosis can also cause abnormal bleeding and discomfort. If the bleeding persists or is accompanied by severe pain, it would be wise to consult a healthcare provider.


Recommendations for Management
1. Hydration: Increase your fluid intake, especially water, to help flush out your urinary system. This can help alleviate some symptoms of a UTI and reduce irritation.

2. Avoid Irritants: Stay away from potential irritants such as caffeine, alcohol, spicy foods, and artificial sweeteners, which can exacerbate UTI symptoms.

3. Urinate Frequently: Do not hold in urine. Frequent urination can help prevent bacteria from multiplying in the urinary tract.

4. Seek Medical Attention: Given the combination of symptoms—especially the presence of blood in your urine and post-menstrual bleeding—it is crucial to see a healthcare provider. They may perform a urinalysis to check for infection and possibly a pelvic exam to rule out any other issues.

5. Antibiotics: If a UTI is diagnosed, your doctor will likely prescribe antibiotics. It’s essential to complete the entire course of antibiotics even if you start feeling better.

6. Follow-Up: If symptoms persist after treatment or if you experience severe pain, fever, or worsening symptoms, follow up with your healthcare provider immediately.


Prevention Strategies
- Stay Hydrated: Aim to drink plenty of water daily to help prevent UTIs.

- Urinate After Intercourse: This can help flush out any bacteria that may have entered the urinary tract during sexual activity.

- Good Hygiene Practices: Wipe from front to back after using the bathroom and consider using unscented products for personal hygiene to reduce irritation.

In summary, while your symptoms could be indicative of a UTI or other gynecological issues, it is essential to consult a healthcare professional for an accurate diagnosis and appropriate treatment. Early intervention can prevent complications and ensure a quicker recovery.
