Do chemo personality changes happen during treatment?
Does chemotherapy cause personality changes in those undergoing treatment? Does it cause people to have a bad temper?
Yes, you may see changes in the personality of someone who's going through chemotherapy for cancer treatment, either because of the cancer itself or because of the toll that chemotherapy takes on the body and on the spirit.
For most cancer patients, undergoing chemotherapy is both enormously stressful and exhausting for the body. Many people experience extreme fatigue and weakness, as well as nausea, loss of appetite, hair loss, and other side effects. All of these experiences can contribute to personality changes such as shortness of temper, depression, anxiety, and general irritability.
If you are seeing such changes in a cancer patient you love, ask your loved one to mention them to his doctor. Many cancer patients can benefit from antidepressants, which can help with both mood issues and fatigue and other symptoms. Cancer support groups can be an excellent resource for cancer patients under stress, and you may find a caregiver support group helpful for you, as well.
