Metallic Taste as a Side-effect of Chemotherapy & Radiation

Metallic Taste as a Side-effect of Chemotherapy & Radiation - MetaQil

Metallic taste is a common side-effect of chemotherapy and radiation. Many patients experience taste changes during and after treatment, that are often described as metallic. Metallic taste can make even your favorite foods taste unpleasant. This can lead to loss of appetite, interfere with healthy eating habits, and cause inadequate nutrient intake. 

What is Metallic Taste?

Metallic taste is a taste disorder known as dysgeusia. It is defined as an abnormal or impaired sense of taste that is often described as persistent metallic, bitter, sour, or other bad taste in the mouth. Metallic taste can develop suddenly or over longer periods of time and can cause major effects on the taste of foods, leading to changes in appetite and eating habits. 

Metallic Taste and Chemotherapy

Chemotherapy and radiotherapy may cause taste and smell disturbances by destroying taste and olfactory receptor cells. In a study among cancer patients, 29 of 37 (78%) participants described their perceived taste change as metallic. The change was reported after at least two cycles of various chemotherapy treatments.  

Metallic taste is especially common in patients who receive radiation on the neck and head region. Chemotherapy and radiation can cause damage to the cells in the oral cavity which can then result in metallic taste (dysgeusia). The cells in normal taste buds regenerate every 10 days. When radiation therapy kills those cells, they take a longer time to regenerate It is during this time that patients experience taste alterations. 

Chemotherapy medications most associated with taste changes include carboplatin, cisplatin, cyclophosphamide, dacarbazine, dactinomycin, doxorubicin, 5-fluorouracil, levamisole, mechlorethamine, methotrexate, paclitaxel, and vincristine.

The Effects of Metallic Taste on Overall Health

Metallic taste caused by chemotherapy and radiation can significantly decrease a patient’s overall health and quality of life due to resulting changes in nutrition. With metallic taste, even your most favorite foods can taste unpleasant, which can lead to poor nutrition, as it causes aversion to certain foods. This also often leads to people eating less or making poor nutrition choices. 

To mask the unpleasant taste caused by dysgeusia, people choose to eat spicier, saltier, or overly sweet foods. As a result of this, sodium and sugar intake often increase and can lead to complications or cause additional health problems. 

One study showed that some dysgeusia patients begin drinking an excessive amount of water, creating a higher risk for polyuria (production of large volumes of urine), incontinence, and falls in the elderly.
