Hematuria (blood in urine) is significant?


I engaged in intense exercise today, stayed well-hydrated, and consumed two popsicles, drank Meili Guo apple soda, fiber sparkling water, and one liter of water with a vitamin dissolved in it.
For breakfast, I had scallion pancakes, and for lunch, I had mentaiko pasta (purchased from PX Mart) along with a milk crispy cookie.
At around 1 PM, I did a weight loss dance for the first time and completed 4.5 sessions, which left me breathless and unsteady.
Around 2 PM, I suddenly experienced severe abdominal pain and diarrhea, which was quite significant.
Later, around 7 PM, I had more pain and diarrhea again.
By 9 PM, I noticed blood in my urine, and after that, I experienced lower back pain.
I weigh 109 kg and have hypertension, severe depression, and social anxiety.
If there is no hope for my life, I wish for euthanasia.

Hello: There are many causes of hematuria; it could be due to kidney stones, inflammation, or even rhabdomyolysis after exercise.
Dietary factors can cause temporary reddish urine (due to certain pigments), but I personally recommend that if you experience blood in your urine for 2-3 consecutive times, you should definitely seek medical evaluation.
Wishing you good health.

Experiencing blood in urine, especially after intense exercise, can be alarming and warrants immediate attention. The presence of blood in urine, known as hematuria, can arise from various causes, particularly after engaging in strenuous physical activity.
Firstly, it's essential to understand that intense exercise can lead to a condition known as "exercise-induced hematuria." This phenomenon occurs when the body undergoes significant physical stress, which can cause trauma to the kidneys or urinary tract. Factors contributing to this condition may include dehydration, vigorous movements, or even the impact of running or jumping, which can lead to microtrauma in the renal system.
In your case, you mentioned having sufficient hydration, which is crucial during exercise, but the combination of intense activity and possibly underlying health conditions could still lead to complications. Given your weight and history of high blood pressure, your body may be under additional strain during physical exertion. Moreover, the abdominal pain and diarrhea you experienced could indicate gastrointestinal distress, which might be linked to the intensity of your workout or dietary choices prior to exercising.

The sudden onset of abdominal pain followed by diarrhea and then hematuria suggests that there could be multiple factors at play. For instance, the abdominal pain could be a sign of a gastrointestinal issue, while the blood in your urine may indicate a separate issue related to your urinary tract or kidneys. The fact that you also experienced lower back pain after the hematuria could suggest that the kidneys are involved, as they are located in the lower back region.

It's crucial to note that while some cases of exercise-induced hematuria resolve on their own, persistent or recurrent hematuria should not be ignored. If you continue to see blood in your urine or if the symptoms worsen, it is imperative to seek medical evaluation. A healthcare professional may recommend imaging studies, such as an ultrasound or CT scan, and laboratory tests to assess kidney function and rule out any serious underlying conditions, such as kidney stones, infections, or even more severe issues like tumors.

In addition to the immediate concern of hematuria, your overall health and mental well-being are also important. You mentioned struggling with severe depression and social anxiety, which can significantly impact your physical health. It may be beneficial to seek support from mental health professionals who can help you navigate these feelings and improve your overall quality of life.

In summary, while exercise can lead to temporary hematuria, the combination of your symptoms—abdominal pain, diarrhea, and blood in urine—suggests that a thorough medical evaluation is necessary. Please prioritize your health and seek medical attention to address these concerns. Remember, you are not alone, and there are resources available to help you through both your physical and mental health challenges.
