Falling sick with diarrhea now and then isn't unusual. The things that can ordinarily cause diarrhea can affect cancer patients too. But, there are additional causes of it in cancer patients, such as:

  • Cancer treatment: Cancer treatment methods, including chemotherapy, radiotherapy, and immunotherapy, can cause diarrhea.
  • Infections: Patients undergoing Cancer treatment are more susceptible to catching hold of diseases, which can result in diarrhea. Antibiotics consumed to treat the infection-causing germ can prolong diarrhea.
  • Cancer: Certain types of cancer are known to cause diarrhea, such as neuroendocrine tumors, colon cancer, and pancreatic cancer.

Whatever causes it determines its duration and severity. You must get in touch with your doctor or nurse and talk to them in detail about your situation.

How to treat diarrhea?

Diarrhea is treated depending on its severity. Changing your diet can stop mild diarrhea, but severe Diarrhea may require medication. Sometimes, doctors prescribe intravenous fluids to replace the lost fluid. If this disease is diagnosed as one of the cancer treatment side effects, then the doctor might change the course of treatment.

Treating Diarrhea in Cancer Patients

In any case, you can try to stop diarrhea from getting worse by altering what you eat and drink. Take one of the following actions:

  • Add more probiotics: Yogurt and dietary supplements have probiotics in generous amounts. Probiotics are bacteria, beneficial in nature, which can help restore healthy digestion. Two examples of probiotics are Lactobacillus and Bifidobacterium. If you have undergone a bone marrow transplant before, then you must consult with your doctor regarding the intake of probiotics.
  • Make sure you drink clear liquids: Once you catch diarrhea, it's better to resort to clear liquids such as clear broth, apple juice, and ice pops. Sports drinks, gelatin, and clear juices like peach, apricot, cranberry juice, and pear nectar are better than water because they have sugar and salt in them. Salted lime water and salted buttermilk can replace fluid-electrolyte losses. Avoid apple juice as it can induce this disease. Stay off from orange, pineapple, and tomato juices as they are too acidic. Forbid yourself from taking grapefruit juice as it can interfere with chemotherapy, radiotherapy, and other medications.
  • Food items high in soluble fiber: Food items such as rice kanji, bananas, apples, oranges, and sweet lime, can help in holding the stools back.
  • Drink plenty of water: Drink water to stay rehydrated and to prevent severe dehydration. To treat dia, you must take in 8-12 cups of water a day.
  • Bland food items with low fiber content: Food such as bananas, poached or boiled eggs, applesauce, toast, and rice can help reduce bathroom visits. Make sure that you stop the diet after 72 hours as it doesn't guarantee high nutrition.
  • Stay off from food that irritates your digestive tract: These include spicy and fried foods, apart from alcohol, dairy products, high-fat diets, and beverages with caffeine. These can give you gas troubles.

Don't forget to have your meals on time, and five to six small meals a day would suffice. Once you start feeling better, you can go back to your regular diet.
