About Bloody Diarrhea

Overview

Bloody diarrhea refers to any episode of diarrhea where the loose or watery stool contains visible red blood. It is a sign of an invasive infection in the gastrointestinal tract, particularly in young children in underdeveloped and developing countries. Bloody diarrhea is associated with intestinal damage and nutrient deterioration, and it can last longer, and have more complications compared to watery diarrhea. It can negatively affect a child's growth and has a high case fatality rate. Approximately 10% of all diarrheal episodes globally have visible blood in the stools. In underdeveloped and developing countries, most cases of bloody diarrhea in young children are caused by invasive bacteria, while non-bacterial pathogens account for less than 3% of cases.

Causes and Risk Factors

The root causes of bloody diarrhea include:

Invasive enteric infection: This refers to an infection caused by invasive bacteria that can damage the intestines and lead to bloody diarrhea. Young children in underdeveloped and developing countries are particularly at risk.

The non-modifiable risk factors of bloody diarrhea include:

Age: The incidence of bloody diarrhea is highest during the weaning period when children start walking, crawling, and consuming solid food.
Gender: Male children have been found to be at a higher risk of developing bloody diarrhea.

The modifiable risk factors of bloody diarrhea include:

Sanitation: Inadequate sanitation, including poor toilet facilities and contaminated water sources, increases the risk of bacterial infections that can cause bloody diarrhea.
Hygiene practices: Lack of handwashing facilities or improper disposal of children's stools can contribute to the spread of bacteria and increase the risk of bloody diarrhea.

These risk factors can vary depending on the specific circumstances and geographical location. Therefore, it is always advisable to consult with a healthcare professional for personalized advice and guidance.

Symptoms

The most common early symptoms of bloody diarrhea include:

Passing loose, watery stools with blood
Abdominal pain and cramping
Fever

As bloody diarrhea progresses or becomes more severe, additional symptoms may occur. These can include:

Chills
Lack of bowel control
Frequent vomiting
Dehydration, which may cause dry mouth, thirst, dry eyes, and infrequent urination

In some cases, bloody diarrhea can be a sign of a foodborne illness. You should seek medical attention If you experience any of the following symptoms:

Weight loss
Diarrhea leading to dehydration
Neurologic involvement (such as paresthesias or motor weakness)
Sudden onset of nausea, vomiting, and diarrhea
Severe abdominal pain

Remember, these symptoms can vary depending on the individual and the underlying cause of the bloody diarrhea. It is always best to consult with a healthcare professional for an accurate diagnosis and appropriate treatment.

Diagnosis

To diagnose bloody diarrhea, medical professionals typically perform the following examinations, tests, and procedures:

Visual Exam: A routine visual exam is conducted to identify conditions such as anal fissures and constipation.
Stool Sample Test: A stool sample may be collected to test for parasites, bacteria, fungi, and viruses.

For determining the stage or severity of bloody diarrhea, additional examinations, tests, and procedures may be performed:

Colonoscopy: This procedure involves inserting a flexible tube with a camera into the colon to examine the lining for abnormalities.
CT Scan: A computed tomography (CT) scan provides detailed images of the abdomen to detect any structural abnormalities or complications.
Endoscopy: This procedure involves inserting a flexible tube with a camera into the digestive tract to examine the esophagus, stomach, and small intestine.
Ultrasound: An ultrasound uses sound waves to create images of the abdominal organs and can help identify any abnormalities.

These tests can provide your doctor with a clearer picture of what is causing the bloody diarrhea and help determine the appropriate treatment plan. Remember, it is important to consult with your healthcare professional for personalized advice and guidance.

Treatment Options

The goals of treatment for Bloody Diarrhea include:

Resolving the infection: The main focus is to eliminate the underlying cause of the bloody diarrhea, which is usually an invasive microbial infection. This can be achieved with antimicrobial agents that specifically target the infecting organism.
Managing dehydration: Bloody diarrhea can lead to fluid and electrolyte imbalances, so it is important to manage dehydration. This is typically done through oral rehydration therapy, which involves drinking a solution that contains electrolytes and fluids to replace those lost during diarrhea.
Preventing complications: Children with bloody diarrhea are at a higher risk for complications such as sepsis, so close observation and monitoring are crucial. In severe cases, hospital admission may be necessary.
Providing supportive care: Resting the digestive system and maintaining proper nutrition are important aspects of treatment. Continuing to feed or increase breastfeeding is recommended, as well as providing smaller, more frequent meals that are easier to tolerate.
Addressing nutritional deficiencies: Nutritional supplementation, particularly with zinc, is often recommended in the treatment of bloody diarrhea. Zinc supplementation can help restore nutrient levels and support overall recovery.

It is important to note that specific medication types and therapies may vary depending on the underlying cause of the bloody diarrhea. Always consult with a healthcare professional for personalized advice and treatment options.

Medication dosing may be affected by many factors. Check with your health care professional about dosing for your individual situation. Other side effects can occur. Check with your health care professional or read the information provided with your medication for additional side effect information.
