Chemotherapy drugs and radiation can destroy all types of healthy blood cells and harm the body’s production of new ones. Low levels of red blood cells (the cells that carry oxygen) can lead to anemia, which causes fatigue, paleness, shortness of breath, and a fast heartbeat.
What nutrients are depleted by chemotherapy?
Deficiencies of vitamins B1, B2, and K and of niacin, folic acid, and thymine also may result from chemotherapy. Nutritional deficiencies are chemically correctable; however, the tumor must be eradicated to relieve cachexia.
What damage does chemotherapy do to the body?
Some chemo drugs can damage cells in the heart, kidneys, bladder, lungs, and nervous system. Sometimes, you can take medicines with the chemo to help protect your body’s normal cells. There are also treatments to help relieve side effects.
What cells are destroyed in chemotherapy?
Chemotherapy kills cells that are in the process of splitting into 2 new cells. Body tissues are made of billions of individual cells. Once we are fully grown, most of the body’s cells don’t divide and multiply much. They only divide if they need to repair damage.
What cells in our body are affected by chemotherapy the most?
The “normal” cells most commonly affected by chemotherapy are the blood cells, the cells in the mouth, stomach and bowel, and the hair follicles; resulting in low blood counts, mouth sores, nausea, diarrhea, and/or hair loss. Different drugs may affect different parts of the body.
Can chemo cause B12 deficiency?
The majority of these cases do not have anemia. Causes other than B12 deficiency include folate deficiency, azidothymidine (AZT) therapy, chemotherapy, elevated alcohol intake and/or liver dysfunction, hypothyroidism, myelodysplastic syndrome, and multiple myeloma.
Can chemo malabsorption?
Digestive discomfort for patients receiving chemotherapy or radiation therapy often comes in the form of diarrhea, vomiting, nausea and nutrient malabsorption. As a consequence, patients often experience dehydration and a dangerously low appetite.

What are the three rapidly dividing cells affected by chemotherapy?
Cancer cells typically grow and divide more rapidly than normal cells. The fast-growing normal cells most likely to be affected by chemotherapy are blood cells forming in the bone marrow, and cells in the digestive tract, reproductive system, and hair follicles.
Does chemotherapy permanently weaken the immune system?
It varies depending on the person and the type of chemotherapy, but for a typical patient who receives immunosuppressive chemotherapy, we see the immune system become more and more impaired over the next four to seven days.
Why does chemotherapy weaken the immune system?
Chemotherapy kills fast-growing cells, which includes many healthy cells, along with cancer cells. Bone marrow cells are frequently damaged and unable to produce white blood cells. This hampers your immune system.
Why does chemo change your face?
Skin changes also occur during chemotherapy. Certain chemotherapy drugs can cause temporary redness in the face and neck. This happens when the blood capillaries, which are the smallest part of blood vessels, enlarge and expand. The skin also can get dry, become darker or even more pale.
