Dealing with the Side-Effects of Cancer Medication

by Team Onco

For many, the treatment for cancer is as terrifying as the disease itself. Cancer treatment is well known for its side-effects rather than what it actually does to the body. Many times, the treatment side-effects persist even after the treatment and may take a few weeks to months to fade away.

Every person’s body reacts differently when it comes to the side-effects of cancer treatment. They may also vary depending on the type of medication, duration and the patient’s general health. Following are some of the common side-effects and their corresponding management strategies.

Anaemia and low blood cell counts

Sometimes, cancer treatment or the cancer itself can cause anaemia, where the haemoglobin levels fall below normal.

Chemotherapy may lead to low blood counts, causing the possibility of a variety of symptoms. The symptoms depend on the type of low blood cell count.  Before every cycle of administering the chemotherapy, blood count will have to be tested.

Initially, one may not notice any symptoms, but as blood count drops down further, the person may experience shortness of breath, fatigue, and light-headedness. This may result in either delay of cancer treatment or a requirement of reduced drug dose.

Balance activity and rest

Consider engaging in activities according to your tolerance levels. Prioritize important activities and choose to work when you have the most energy during the day. Seek help for those activities which do not require your involvement.

Check for symptoms

Be vigilant for any unusual symptoms and inform the healthcare provider immediately. It is better to maintain a log of the symptoms, recording their time of occurrence and conditions that are making them worse or better, which might  help in better planning of your activities.

Eat an iron-rich diet

Including iron-rich foods in your diet with your doctor’s advice can help to improve the falling blood counts. Such foods may include leafy vegetables like spinach, beans, eggs, lentils, sweet potatoes, meat etc.

Depending on the severity of anemia, management will be prescribed by your doctor.


Fatigue is a common problem experienced by many cancer patients. Often, cancer-associated conditions, such as anaemia, pain and stress can also cause or worsen fatigue.

Sometimes patients may need to permanently change their lifestyle to prevent fatigue and cope with the long-term effects of treatment.

Identify your energy levels

Evaluate yourself and make a note of the times when you feel energetic or tired. It helps to manage your activity and identify the factors contributing to energy depletion.

Plan your activity

Choose activities that are relaxing and manage your energy levels. Mild exercise may help you to feel better and lower your stress levels.

A short nap for less than one hour during the day can help you feel re-energised, however, excessive rest may make you feel more tired. Balance your activities and rest before you feel fatigued. Choose your tasks that are most important and seek help for others.

Aim for good health

Eat a well-balanced and nutritious diet, such as foods with high amounts of protein and calories. Break your daily diet into many small meals instead of having a few large meals.

Drink plenty of water to stay active and energised. Additionally, regular exercise may help you to regain strength and stamina.


Diarrhoea is also one of the common side-effects experienced by cancer patients. It can be mild, severe and persistent.

You may have thin or watery stools or a sense of urgency to have a bowel movement. In some people, diarrhoea may be accompanied by abdominal bloating or cramps.

Management of diarrhoea

Stay hydrated

Consume at least eight to twelve glasses of water in a day. Consider having clear broths or pulp-less fruit juices.

Take good care of your stomach

Make good food choices that are easy on the stomach and don’t worsen the condition. Consider eating small frequent meals rather than large meals.

Maintain anal hygiene

Frequent bowel movements may cause soreness in the rectal area. Try warm or sitz baths to relieve itchiness, burning, or pain during bowel movements.

Avoid rubbing, instead pat the area clean using a soft towel.

Consult your physician when required

Severe diarrhoea may lead to dehydration that may impose serious complications. Inform your doctor if you have diarrhoea more than three to four times a day. Take antidiarrheal medicine only with doctor’s advice.

Nausea and vomiting

Nausea is another common symptom experienced by cancer patients which may last from a few hours to several weeks post-treatment. It may or may not be accompanied by vomiting.

Often medicines are used to prevent or control such conditions and other serious problems, such as malnutrition and dehydration that might result from persistent vomiting.

Watch your diet

Eat slowly and consider eating small frequent meals rather than a large meal. Avoid spicy foods, sweets, and foods that are hard to digest.

Also, stay away from foods with a pungent smell. Identify the time when you don’t feel more nauseous and try eating more food during such times.

Some people may find it better to eat a small snack before treatment, while others prefer to avoid eating or drinking before and after treatment. However, it is recommended to avoid eating or drinking for one-hour post-treatment.

Changes in sense of taste

Metallic taste in the mouth during cancer treatment is common and may resolve over time. Patients often complain that the food seems to have no taste or doesn’t taste as it was before treatment.

Maintain oral hygiene

Cleaning your mouth before having food might help food taste better. Additionally, good oral hygiene helps to prevent other problems associated with cancer treatment.

Try to improve the flavours and taste of the food by adding spices/seasoning or sweetening agents. Some people may find chilled versions better.

People with cancer treatment may have difficulty in eating due to the side effects like mouth and throat problems, nausea and vomiting or fatigue. However, adherence to good nutritional practices are essential for better recovery and for reducing the risk of infections.

Management of loss of appetite

Hydrate your body

Drinking plenty of fluids is important, especially when experiencing a loss of appetite, to avoid other complications like dehydration.

Try sipping small amounts of fluids throughout the day. Consider drinking beverages after meals instead of before or during a meal to increase your food intake.

Practise healthy eating

Consider eating small, frequent meals or snacks from six to eight times a day rather than having large meals. Try to include nutrient-dense foods with higher amounts of protein and fats. Avoid foods with low nutritional values.

Stay active

Being active like a daily short walk also helps to improve your appetite.
