Diarrhea with Blood: When to Seek Medical Help - Surgery

I would like to inquire about my gastrointestinal condition, experiencing diarrhea with blood?


In the past two weeks, due to weight loss, I have been eating lighter foods (boiled chicken breast, fish, boiled eggs, cabbage, a little chili, and grapes).
However, I have noticed that my bowel movements have been consistently diarrhea for about five days, and in the last two days, I have found a small amount of blood on the toilet paper after wiping.
I would like to know what this situation might be.
Do I need to go to the hospital for treatment? How much might it cost?

Due to persistent diarrhea, the intestinal mucosa experiences excessive friction and damage, leading to a bleeding condition.
If this continues, it may allow previously symbiotic bacterial strains to penetrate through the damaged mucosa and attack the body, resulting in conditions such as enteritis, abdominal pain, elevated white blood cell count, and enlarged abdominal lymph nodes.
If the diarrhea is caused by a specific diet, one can first try reverting to a normal diet (at least removing spicy foods) to see if there is any improvement in the diarrhea.
In Taiwan, medical treatment is covered by the National Health Insurance, and the fees vary depending on the level of the medical institution you visit.

Diarrhea with blood can be a concerning symptom that warrants medical attention. Given your recent dietary changes and the presence of blood in your stool, it is important to understand the potential causes and when to seek help.

Firstly, diarrhea can be caused by a variety of factors, including dietary changes, infections (viral, bacterial, or parasitic), food intolerances, or underlying gastrointestinal conditions such as inflammatory bowel disease (IBD) or irritable bowel syndrome (IBS). The fact that you have been consuming a diet that is significantly different from your usual intake could contribute to gastrointestinal upset, but the presence of blood is a red flag that should not be ignored.

The blood you noticed on the toilet paper could indicate several possibilities. It might be due to hemorrhoids, which are swollen veins in the rectal area that can bleed during bowel movements, especially if you are experiencing diarrhea. However, blood can also be a sign of more serious conditions, such as:
1. Infectious Colitis: Infections caused by bacteria (like E. coli, Salmonella, or Shigella) can lead to bloody diarrhea. This is often accompanied by abdominal pain, fever, and sometimes vomiting.

2. Inflammatory Bowel Disease (IBD): Conditions such as Crohn's disease or ulcerative colitis can cause chronic diarrhea with blood. These conditions often require long-term management and can lead to complications if untreated.

3. Diverticulitis: Inflammation or infection of small pouches that can form in the walls of the colon can also lead to symptoms of diarrhea and blood in the stool.

4. Colon Polyps or Cancer: Although less common, especially in younger individuals, polyps or colorectal cancer can present with blood in the stool and should be evaluated, particularly if there are other risk factors.

Given that your diarrhea has persisted for five days and is accompanied by blood, it is advisable to seek medical attention. A healthcare provider can perform a thorough evaluation, which may include a physical examination, blood tests, stool tests, and possibly imaging studies or a colonoscopy, depending on the findings.

As for the cost of treatment, it can vary widely depending on your location, the healthcare facility, and whether you have insurance coverage. In the United States, an emergency room visit can range from $150 to over $3,000, depending on the severity of the case and the tests performed. If you have health insurance, your out-of-pocket costs may be significantly lower, but it is essential to check with your provider for specific coverage details.

In summary, while dietary changes can lead to temporary gastrointestinal disturbances, the presence of blood in your stool is a symptom that should be evaluated by a healthcare professional. It is better to err on the side of caution when it comes to potential gastrointestinal issues, especially those that involve blood. Please consider visiting a doctor or an urgent care facility to get the appropriate care and peace of mind.
