Physical Side Effects

Colorectal cancer treatments can throw a few physical curveballs your way. From fatigue to digestive issues, these side effects vary based on the type of treatment and how your body responds. Understanding what’s ahead and having some tricks up your sleeve can make a real difference. Here’s a guide to common physical side effects of colorectal cancer treatment and practical ways to manage them, so you can stay as comfortable and in control as possible.

Fatigue: That Deep Exhaustion

Fatigue is super common with chemotherapy, radiation, and other treatments. It’s not your typical tired—it’s a deep, heavy exhaustion that can stick around even with rest.

What to Expect: You might feel both physically and mentally drained, making daily tasks feel a bit harder. Fatigue can ebb and flow or linger day after day.

Tips for Managing Fatigue:

  • Balance Rest with Light Movement: Short walks or gentle stretching can boost energy, even if you don’t feel like it at first.

  • Prioritize What Matters: Focus on essential tasks and ask for help when needed.

  • Listen to Your Body: Rest when you need it—this isn’t the time to push through.

In Short: Rest, move gently, and take breaks to keep fatigue manageable.

Nausea and Vomiting: Keeping the Queasiness in Check

Nausea and vomiting are most common with chemotherapy but can show up with other treatments too.

  • What to Expect: Nausea might come as mild queasiness or strong waves that make it hard to eat.

  • Tips for Managing Nausea:

    • Hydrate: Sip on water, ginger tea, or electrolyte drinks to stay hydrated and soothe your stomach.

    • Small, Frequent Meals: Light, regular snacks can help prevent nausea from hitting too hard.

    • Ask About Meds: Anti-nausea medications can be lifesavers—ask your doctor what’s available.

In Short: Hydrate, eat small bites, and use prescribed medications to keep nausea under control.

Appetite Loss: When Food Doesn’t Sound Good

Losing your appetite is common, especially with chemotherapy or nausea.

  • What to Expect: You may feel less hungry, or certain foods might lose their appeal.

  • Tips for Managing Appetite Loss:

    • Go for Nutrient-Dense Foods: Focus on calorie-packed options like smoothies, yogurt, nuts, and avocados.

    • Experiment with Flavors: Try bland, cool foods or spices to find what feels easiest to eat.

In Short: Small portions of nutrient-rich foods can help keep your strength up, even if you’re not hungry.

Digestive Issues: Dealing with Diarrhea and Constipation

Colorectal cancer treatments often affect the digestive system, leading to issues like diarrhea or constipation.

  • What to Expect: Treatment may lead to one or both digestive extremes.

  • Tips for Managing Digestive Issues:

    • For Diarrhea: Drink lots of fluids to stay hydrated, stick with foods like bananas, rice, and toast, and ask your doctor about over-the-counter help.

    • For Constipation: Increase fiber with fruits, vegetables, and whole grains, stay hydrated, and get moving with light exercise.

    • Track Your Diet: A food diary can help you spot any digestive triggers or aids.

In Short: Staying hydrated, eating mindfully, and tracking what helps or hurts can make a difference with digestive issues.

Mouth Sores and Dry Mouth: When Eating Hurts

  • Tips for Managing Mouth Sores and Dry Mouth:

Hair Loss and Skin Changes: Taking Care of Your Appearance

Hair loss and skin changes are common with chemotherapy, but everyone’s experience is different.

    • Gentle Products: Use fragrance-free, gentle shampoos, lotions, and soaps to avoid irritation.

    • Sun Protection: Wear sunscreen, hats, and protective clothing to shield sensitive skin.

    • Cover Options: If you experience hair loss, hats, scarves, or wigs can add comfort and confidence.
