Is cancer treatment causing intestinal problems? Let's learn about radiation enteritis.

If you are undergoing radiation therapy for cancer, or if someone you know is undergoing this treatment, you probably know that sometimes you experience minor intestinal discomfort. So today we are going to talk about the effect that radiation therapy can have on the intestines, a condition called Radiation Enteritis . There is nothing to fear, if you are properly informed about this, you can reduce many problems.

What is Radiation Enteritis?

Simply put, Radiation Enteritis is damage or inflammation to your intestines caused by radiation therapy . As you know, radioactive substances are used to treat diseases like cancer to destroy abnormal cells. This is a common treatment not only for cancer but also for some blood-related diseases.

This condition has several other names, and your doctor may use one of these names:

• `(Pelvic radiation disease)`
• `(Radiation colitis)` (This is a name given to inflammation that occurs specifically in the large intestine)
• `(Radiation enteropathy)`
• ``(Radiation-induced bowel disease)''
• `(Radiation mucositis)` (This refers to damage to the mucous membrane)

Are there types of this?

Yes, there are two main types of Radiation Enteritis. They are:

1. Acute Radiation Enteritis: This occurs while you are receiving radiation therapy. The good news is that these symptoms usually go away completely within a few weeks.

2. Chronic Radiation Enteritis: This is a little different. It occurs months, even years, after treatment has finished. The problem here is that the symptoms can stay with you for a long time and sometimes complications can occur.

How common is Radiation Enteritis? Who is at higher risk?

In the past, this condition was relatively common. That is, when old radiation treatments were used, about half of people who received treatment to the abdomen or pelvis would develop radiation enteritis. However , with modern radiation treatments, the risk of developing chronic radiation enteritis has been greatly reduced .

However, some people may be at a slightly higher risk than others. There are several reasons for this:

• Conditions that reduce blood flow to the intestines: For example, if you have diabetes mellitus or high blood pressure, the amount of blood flowing to the intestines may be reduced, and radiation damage may take longer to heal, or the damage may be worse.
• An existing inflammatory condition in the tissues: Imagine you have a condition like pelvic inflammatory disease. Then, because that area is already sensitive, it is more likely to be damaged by radiation.
• Other treatments that kill cells: If you are receiving other treatments, such as chemotherapy, along with radiation therapy, the risk may increase because it also affects cells.
• Poor nutritional status: If the body does not receive the proper nutrition it needs, the cell repair process is impaired.
• Smoking and other tobacco use: These reduce the body's ability to heal.
• Having scars from previous abdominal surgery: These things can also increase the sensitivity of the intestines.

How does radiation therapy affect the intestines?

Radiation therapy is a continuous exposure to radioactive substances, usually for several weeks. When this radiation also hits healthy cells, it causes inflammation and tissue damage . The cells that line the inside of our intestines (that is, the cells that line the intestines) are particularly sensitive to the effects of radiation.

Repeated exposure to radiation can destroy cells that help prevent infection and regulate fluid levels in the body. The higher the dose of radiation you receive, and the larger the area of ​​bowel treated, the greater the risk of developing radiation enteritis.

What are the symptoms?

The symptoms of radiation enteritis can vary slightly from person to person. They also depend on whether it is acute or chronic. The most common symptoms include:

• Abdominal pain and cramping .
• Bloated stomach .
• Diarrhea : Passing loose stools several times a day.
• Loss of appetite .
• Nausea and vomiting .
• Pain when you poop .
• Rectal bleeding or pain .
• Unintended weight loss .
• Feeling the sudden need to defecate (Urgent need to poop) .

If you have one or more of these symptoms, you should see a doctor immediately .

What complications can this cause?

This ongoing inflammation and damage to the intestines can lead to some complications. These are often associated with chronic (radiation) enteritis.

• Dehydration : Diarrhea and vomiting cause the body to lose water and salts.
• Electrolyte imbalances : The amount of salts (such as sodium and potassium) in the body becomes unbalanced.
• Fistula : This is when an abnormal connection, a tube-like structure, forms between your intestines and another nearby organ (e.g., bladder, vagina).
• Intestinal perforation : A hole in the wall of the intestine can occur. This is an emergency.
• Malabsorption : The body is unable to properly absorb nutrients from food.
• Small bowel obstruction : A blockage can occur somewhere in the small intestine.
• Stricture : A part of the intestine becomes narrow, making it difficult for food to pass through.
• Ulcers : Ulcers can form inside the intestines, similar to gastritis ulcers in the stomach. These can sometimes develop into peptic ulcer disease.

Not everyone develops these complications, but if you have symptoms, it's important to tell your doctor without ignoring them.

How is Radiation Enteritis diagnosed?

Doctors often diagnose this condition by asking you about your symptoms and learning about how long you were exposed to radiation therapy .

However, your doctor may recommend a few additional tests to rule out other medical conditions and to understand the severity of your condition. These include:

• Hydrogen breath test to see if bacteria have grown too much.
• Endoscopy (Lower or upper endoscopy) : This involves inserting a tube with a camera into the small intestine to look inside. If necessary, a small piece of tissue (biopsy) can be taken for examination.
• An X-ray examination .
• Other imaging tests : If the X-rays do not provide a clear picture, you may be asked to do a CT scan or MRI.

How is it treated?

Long-term damage to intestinal cells caused by radiation exposure can be difficult to completely heal. However, medical management of radiation enteritis can provide you with relief and prevent complications.

Your treatments may include:

• Antibiotics are prescribed if there are unwanted bacteria in the intestines.
• Antidiarrheals (medicines that stop diarrhea) reduce diarrhea, which control bowel function somewhat.
• Corticosteroids to reduce inflammation in the intestines.
• Pain relievers .

How are complications treated?

The treatment that is right for you will depend on the type of complication you have. For example, conditions such as strictures, fistulas, and perforations often require surgery . If you are not getting enough nutrition, you may need nutritional supplements or tube feeding.

Are there ways to prevent this?

Yes, your medical team can take several steps to protect your intestines during radiation treatment.

• Using custom positioning devices to help keep your body in the same position during treatment.
• Modern treatment methods : For example, methods like ``Intensity-modulated radiation therapy (IMRT)`` can direct radiation only to the exact area needed. This greatly reduces damage to healthy tissue.
• Applying protective shields to your colon or rectum.

You can talk to your doctor about this for more information.

How long does it take to recover?

People with acute (Acute) Radiation Enteritis usually experience relief within a few weeks . However, if you have chronic (Chronic) Radiation Enteritis, it may take several months to fully recover . Sometimes you may have to live with the symptoms and manage them.

Things to remember when living with Radiation Enteritis

In most cases, the benefits of cancer treatment far outweigh the risks of developing radiation enteritis. Therefore, even if you are experiencing discomfort, it is not a good idea to stop radiation treatment without your doctor's advice.

If you are concerned about how radiation enteritis may be affecting your health, be sure to talk to your doctor . He or she can explain your options, such as changing the frequency or dose of radiation therapy, or other treatments for your radiation enteritis symptoms.

What can you do to get relief during radiation treatment?

Taking care of your diet and fluid intake can help reduce discomfort and speed up the healing process.

Stay away from these types of foods and drinks that are difficult to digest:

• Alcohol.
• Carbonated beverages (things like soda) `(Carbonated beverages)`.
• Dairy products (some people have difficulty digesting these, so be careful. It's best to ask your doctor).
• Greasy, processed or fried foods (e.g. sausages, french fries).
• High-fiber foods, like raw vegetables (e.g. raw cabbage, carrot salad). It is best to eat these boiled.
• Spicy foods.

Instead, choose nutritious foods that are easy on your stomach:

• Baked or broiled lean meats, like chicken.
• Fruits like bananas and apples.
• Canned fruits and vegetables (but choose those with low sugar). Fresh, well-cooked vegetables and fruits are also good.
• Clear broth (like chicken soup).
• Cooked vegetables, including carrots and potatoes.
• Bread toast (without butter) `(Dry toast)`.
• Eat small amounts of things like rice, noodles, and curd.

The most important thing is that if you feel anything uncomfortable, tell your doctor. Then he can give you the right advice.
