Abdominal Pain: Possible Causes and Concerns - Gastroenterology and Hepatology

Abdominal issues?

Hello Doctor: My boyfriend is 24 years old and has been experiencing a dull pain in his lower right abdomen for the past week.
Two days later, he developed a high fever reaching 39 degrees Celsius.
After the fever subsided, he has been experiencing persistent hiccups.
His bowel movements have contained some traces of blood.
Could you please advise which area might be problematic? Thank you for your response!

Right lower abdominal pain must consider issues related to the appendix, colon, and small intestine (ileum).
Additionally, with a high fever reaching 39 degrees Celsius, acute appendicitis should be the primary consideration, followed by enteritis or diverticulitis (though the likelihood is lower in young individuals).
Particularly, if there is blood in the stool, the possibility of a gastrointestinal source increases significantly.
The blood can be classified as bright red or dark red; the former usually originates from the rectum or lower colon, while the latter may come from the upper colon.
Acute appendicitis is less likely to cause bloody stools.
Therefore, my recommendation is to first obtain an abdominal X-ray and perform a blood test to check for elevated white blood cell counts or signs of anemia.
If the condition does not improve, further evaluation with a colonoscopy is necessary.
It is important to emphasize that acute appendicitis is a surgical emergency; delaying treatment can lead to peritonitis, which poses a life-threatening risk.
However, the initial symptoms are often atypical, so close monitoring is essential until the possibility of appendicitis is ruled out!

Understanding abdominal pain, especially when accompanied by fever and changes in bowel habits, is crucial for determining the underlying cause and appropriate treatment. In your boyfriend's case, the symptoms he is experiencing—right lower abdominal pain, fever, and blood in the stool—could indicate several potential medical conditions that warrant immediate attention.

1. Appendicitis: One of the most common causes of right lower abdominal pain, especially in younger individuals, is appendicitis. This condition occurs when the appendix becomes inflamed and can lead to severe pain, fever, and sometimes gastrointestinal symptoms like nausea or changes in bowel habits. The presence of fever and localized pain in the right lower quadrant strongly suggests this possibility.

2. Gastrointestinal Infections: Another potential cause could be a gastrointestinal infection, which can lead to symptoms such as abdominal pain, fever, and diarrhea or changes in stool consistency. Infections can be viral, bacterial, or parasitic, and some may cause bloody stools, particularly if there is significant inflammation or ulceration of the intestinal lining.

3. Diverticulitis: Although more common in older adults, diverticulitis can occur in younger individuals. It involves inflammation or infection of diverticula (small pouches that can form in the walls of the colon) and can present with localized pain, fever, and changes in bowel habits, including blood in the stool.

4. Inflammatory Bowel Disease (IBD): Conditions such as Crohn's disease or ulcerative colitis can also cause abdominal pain, fever, and bloody stools. These chronic conditions involve inflammation of the gastrointestinal tract and can lead to significant complications if not diagnosed and treated promptly.

5. Urinary Tract Issues: While less likely given the specific symptoms, urinary tract infections (UTIs) or kidney stones can sometimes cause referred pain to the lower abdomen and may be associated with fever.

Given the combination of symptoms—especially the fever and blood in the stool—it is essential that your boyfriend seeks medical attention as soon as possible. A healthcare professional will likely perform a physical examination and may order diagnostic tests such as blood tests, imaging studies (like an ultrasound or CT scan), and possibly a stool test to identify any infections or other underlying issues.

In summary, the symptoms your boyfriend is experiencing could be indicative of several serious conditions, including appendicitis, gastrointestinal infections, diverticulitis, or inflammatory bowel disease. Prompt medical evaluation is crucial to determine the exact cause and initiate appropriate treatment. Delaying medical care could lead to complications, especially if the underlying issue requires surgical intervention or specific medical management.
