Gastrointestinal Issues After Heart Surgery: When to Seek Help

Hello?

Dear Vice Dean Tsai,
My father underwent a cardiac catheterization procedure recently and has been experiencing frequent abdominal bloating, which has led him to eat very little.
He hasn't had a bowel movement for the past two days, and today while trying to defecate, he found that he still couldn't pass stool.
After squatting in the restroom for a while, he noticed some blood.
Could you please advise if this could be considered gastrointestinal bleeding? Should he seek immediate medical attention? Thank you.

If it is not gastric bleeding, immediate consultation with a colorectal surgeon is necessary, as the bleeding may be caused by hemorrhoids.
A sigmoidoscopy can provide answers.
Below is information related to gastric bleeding:
Symptoms may include the presence of blood in vomit or black, tarry stools.
Patients with chronic gastric bleeding may exhibit signs of anemia, such as fatigue, pallor, chest pain, and lightheadedness.
Severe gastric bleeding can lead to symptoms such as tachycardia, hypotension, decreased urine output, chills, and cold extremities.
Insufficient cerebral blood flow due to blood loss may result in confusion, disorientation, drowsiness, or even shock.
Causes include gastric ulcers, duodenal ulcers, or cirrhosis.
Gastritis or gastric cancer caused by aspirin or Helicobacter pylori infection, as well as hematological disorders, can also be contributing factors.
Treatment for patients with persistent gastric bleeding and significant symptoms requires hospitalization.
Those with excessive blood loss may need blood transfusions.
Generally, gastric bleeding can be managed through endoscopic treatment to achieve hemostasis, such as cauterizing bleeding vessels or injecting medications to promote clot formation within the vessels.
If these methods are ineffective, surgical intervention may be necessary.
Prevention involves early diagnosis and treatment of underlying conditions that may cause gastric bleeding.

More Info

After heart surgery, gastrointestinal issues can arise due to various factors, including medication side effects, changes in diet, and the body's response to surgery. In your father's case, the symptoms of abdominal bloating, constipation, and the presence of blood in the stool are concerning and warrant immediate medical attention.

Firstly, it's essential to understand that after heart procedures, patients often experience changes in their gastrointestinal function. This can be attributed to several reasons:
1. Medications: Post-surgery, patients are typically prescribed various medications, including anticoagulants, pain relievers, and other heart-related drugs. Some of these medications can lead to gastrointestinal side effects such as constipation, bloating, and even gastrointestinal bleeding. For instance, anticoagulants can increase the risk of bleeding, and non-steroidal anti-inflammatory drugs (NSAIDs) can irritate the gastrointestinal lining.

2. Dietary Changes: After heart surgery, patients may be advised to follow a specific diet that could be low in fiber or difficult to digest, leading to constipation and bloating. If your father has been eating less due to discomfort, this could exacerbate the issue.

3. Surgical Impact: The stress of surgery can affect gut motility, leading to temporary gastrointestinal dysfunction. This can manifest as bloating and constipation.

4. Underlying Conditions: It's also possible that underlying gastrointestinal conditions could be exacerbated by the surgery or medications.
Now, regarding your father's symptoms:
- Bloating: This is often a common complaint after heart surgery and can be managed with dietary adjustments, increased fluid intake, and possibly the use of stool softeners or laxatives if recommended by a physician.

- Constipation: Not having a bowel movement for two days, especially after surgery, is concerning. It can lead to discomfort and further complications if not addressed. Encouraging your father to increase his fluid intake and consider high-fiber foods (if permitted by his diet) can help.

- Blood in Stool: The presence of blood in the stool is particularly alarming. This could indicate several issues, including hemorrhoids (which can occur due to straining), gastrointestinal bleeding from ulcers or lesions, or other serious conditions. Given that he has had recent surgery, it is crucial to rule out any complications related to the surgery or medication side effects.

When to Seek Help: Given the combination of symptoms—especially the blood in the stool—it is advisable to seek medical attention immediately. This could involve contacting his cardiologist or primary care physician, or going to the emergency room if the bleeding is significant or accompanied by other symptoms such as severe abdominal pain, dizziness, or fainting.

In summary, while some gastrointestinal issues can be expected after heart surgery, the presence of blood in the stool is a red flag that should not be ignored. Prompt evaluation by a healthcare professional is essential to determine the cause and appropriate treatment. It is always better to err on the side of caution when it comes to health concerns, especially following significant medical procedures.
