Side Effects:

The side effects of common cancer therapies vary according to the treatment and the area of the body undergoing treatment. The following are some side effects and some helpful suggestions. They do not replace, but rather aid, drugs used to relieve these symptoms.

CHEWING AND SWALLOWING DIFFICULTY

Thick liquids such as milkshakes or semisolid foods like mashed potatoes and gravy may be easier to swallow and are less likely to cause aspiration (inhaling food).

PAIN, NAUSEA, VOMITING, DIARRHEA

Eating a meal immediately before or after the administration of the treatment may ease these symptoms. Your position while eating may also contribute to these symptoms.

TASTE ALTERATIONS AND AVERSIONS

• Eat bland foods. Avoid strong flavors like spices, acidic foods, and sour tasting foods.
• Eat cold foods. Avoid hot or warm foods.
• Avoid foods with strong odors.
• If you are experiencing severe nausea, avoid any favorite foods. Eating a food during severe bouts of nausea may cause the development of an aversion to it.

• Increase protein and calories in the diet.
• Eat smaller, but more frequent meals.
• Add powdered milk to foods and beverages.
• Drink mainly calorie-containing beverages such as juices, milk, or sweetened drinks.
• Add extra eggs or egg whites to foods. Never use raw eggs. They may be contaminated with salmonella, which is dangerous for everyone but especially those who are immune-suppressed. Raw eggs also contain a vitamin binder.
• Add diced meat or cheese to sauces, vegetables, soups, and casseroles.
• Snack throughout the day on calorie-dense foods such as nuts, hard candy, and dried fruits.
• Consider using commercially available nutrition supplements. Make your own high-calorie shake by using an instant breakfast drink mix with milk, fruit, cookies, peanut butter, or other favorite mixers.
• Increasing fats in the diet is an excellent way to increase energy consumption, if you are tolerating fats. Add margarine or butter to breads and vegetables. Add gravies and sauces to foods in liberal amounts.
• If you are unable to digest fat, consult with your health care provider for alternative fat sources. Supplements containing medium-chain triglycerides are often recommended for this purpose.

LACTOSE INTOLERANCE

Some cancer patients become unable to digest dairy products, which is called lactose intolerance. Symptoms include bloating, gas, and diarrhea immediately after eating lactose-containing foods.

People with lactose intolerance have trouble digesting the sugar in milk. Lactose intolerance is due to an inability to produce lactase, the enzyme that digests milk. The wall of the gastrointestinal tract produces this enzyme. Fortunately, lactase can be synthetically produced, purchased over-the-counter, or can be taken orally with milk.

You can also buy lactose-free milk at most grocery stores. Cultured dairy products such as yogurt, cheeses, and buttermilk will have less lactose as the active cultures help to digest it. You may be able to tolerate small amounts of lactose occasionally. You may have to restrict lactose entirely from the diet until you have fully recovered from your cancer therapy.

DUMPING SYNDROME

Surgery on the stomach may cause dumping syndrome. If you have dumping syndrome, food is "dumped" into the small intestine 10 or 15 minutes after being swallowed. Ordinarily, food is partially digested in the stomach, then released gradually into the digestive tract.

The presence of undigested food in the intestine leads to abdominal fullness, nausea and crampy abdominal pain. Other symptoms include feeling warm, dizzy, and faint. You may also experience rapid pulse and cold sweats immediately after eating.

Recommendations for dumping syndrome are:

• Eat smaller, more frequent meals.
• Lie down immediately after eating.
• Restrict refined carbohydrates and increase protein and fat in the diet.
• Drink fluids 30 minutes before a meal or 30 - 60 minutes after a meal.

LOSS OF APPETITE

If you are experiencing loss of appetite, adjust the diet to include any foods that appeal to you. Consider asking your doctor about appetite-stimulating drugs.
