Chemo Side Effects

What side effects can I expect from chemo?

Chemotherapy affects everyone differently. How you feel during treatment can depend on several things: your overall health, the type and stage of your cancer, the specific chemotherapy drugs used, and how much of those drugs you’re given. Even your care team can’t predict exactly how your body will respond. Some people have lots of side effects. Others experience very few. No two experiences are the same. 

Chemotherapy works by targeting fast-growing cancer cells. But it can also affect other fast-growing healthy cells in your body, like those in your hair follicles, digestive tract, and skin. That’s what causes many of the common side effects. 

Whether you’re receiving chemo through an IV or taking it by mouth (oral chemotherapy), the potential side effects are similar.

Side Effects: How Your Body May React

Before you begin chemo, ask your doctor or nurse what side effects are most likely with your specific treatment. Here are some of the most common ones to be aware of:

Anemia

A drop in red blood cells, which can leave you feeling tired, weak, or short of breath.

Appetite Changes

You may feel less hungry or notice your taste preferences shifting during treatment.

Constipation

Chemo can slow your digestion. Drinking more fluids, eating fiber, or taking recommended medications can help.

Diarrhea

A faster-than-normal digestive system is also possible. Let your care team know if it’s persistent or severe.

Fatigue

Feeling more tired than usual is one of the most common side effects. Rest when you need to.

Flu-like Symptoms

This can include mild fever, body aches, or chills.

Hair Loss

Not everyone loses their hair, but it’s a well-known side effect of many chemotherapy drugs. If this happens, it’s typically temporary.

Nausea and Vomiting

Anti-nausea medications can help, so don’t hesitate to ask for them.

Neuropathy

Some people experience tingling, numbness, or pain in your hands and feet caused by damage to nerves (your care team may call this “peripheral neuropathy”).

Neutropenia

No matter what side effects you experience, keep your care team in the loop. They can offer ways to manage or reduce symptoms and help you feel more in control throughout your treatment.
