6 Chemotherapy Side Effects Patients Don't Expect

The Chemotherapy Side Effects Most People Don't Know About...

Before undergoing chemotherapy, most people come to expect certain side effects like fatigue, nausea and hair loss. We hear about these side effects so often in pharmaceutical commercials, television shows, and from our loved ones with cancer, that we automatically associate chemotherapy with them. However, the list of possible side effects is long and isn't just exclusive to hair loss or stomach upset. Chemotherapy is a systemic treatment, meaning it affects the whole body with a myriad of possible side effects, some of which aren't easy to talk about during water cooler banter.

When people start experiencing side effects like low libido or yeast infections, it can come as a total surprise. These are the side effects that not many people really talk about. Your doctor most likely gave you an encyclopedia-sized book of information about possible side effects, but because you may not have heard about them beforehand or known someone who experienced them, it's easy to overlook the possibility that you may experience these side effects.

Common Unexpected Chemotherapy Side Effects

1. Low Libido

To the dismay of many, low libido, or the loss of sexual desire, can be a common chemotherapy side effect. Not all chemotherapy drugs cause a decrease in libido, however, and other types of cancer treatment and related side effects are also a culprit.

A change in libido can also be a psychological side effect of treatment -- hair loss, weight loss or gain, and general lack of self-esteem can cause people to lose their sex drive during treatment.

2. Chronic Vaginal Yeast Infections

While vaginal yeast infections do not pose a health risk for women, they can be irritating. Chemotherapy drugs, along with steroids or antibiotics that may be prescribed during treatment, can cause women to develop vaginal yeast infections. Under normal circumstances, yeast infections are easy to treat, but the effects of chemotherapy make it difficult for the body to fight off infections.

During treatment, it is important for women to take steps to prevent yeast infections and treat them properly. Most women find relief with over-the-counter medication, but some women may require prescription medication. Learn more about yeast infections during chemotherapy.

3. Chemo Brain

Cognitive deficit, referred to as "chemo brain" among patients and survivors, is a side effect of treatment that affects cognitive functioning, such as memory and concentration. Affected patients and cancer survivors have reported difficulty concentrating, shortened attention spans, and changes in memory. Research concerning cognitive decline related to chemotherapy is ongoing, but we know little about why it may occur and who is most at risk.

4. Nail Damage

Fingernails and toenails can also be affected by chemotherapy. Nails may become dry, brittle, discolored, or develop lines or ridges. In more severe cases, the nails may even fall off. Not all chemotherapy drugs cause nail damage, but those belonging to the taxane group are most affected by it.

A 2005 study in France found that those who wore special frozen gloves during chemotherapy sessions were less likely to suffer from nail damage than those who did not. Some patients place frozen vegetables or ice packs over their hands and feet to prevent nail damage and also reduce the severity of hand-foot syndrome, another side effect of chemotherapy.

5. Taste Changes

Taste changes are generally not a common side effect of chemotherapy, but can be with certain chemotherapy drugs. Carboplatin, cisplatin, doxorubisin, gemcitabine, and paclitaxel are known to cause taste changes. These changes can be a loss of taste or experiencing metallic, bitter, or sweet taste sensations. This side effect can make eating and drinking difficult, leading to the development of food aversions, which can cause weight loss. There are no medications to prevent or treat taste changes, but there are things you can do to help food and drinks taste better.

6. Acid Reflux

Acid reflux is a common condition, even in people who don't have cancer. It can be a common side effect of chemotherapy and a major source of discomfort. For most people, OTC medications alleviate the problem, but for those who suffer from moderate to severe acid reflux, prescription medication may be needed. Acid reflux usually starts within a few days of beginning treatment and can continue after treatment ends. Read more about acid reflux during chemotherapy.
