When ordinary fatigue may be a sign of anemia
Fatigue is often blamed on stress, poor sleep, work overload or recovery after illness. But if weakness lasts for weeks, does not improve after rest and is accompanied by shortness of breath, dizziness or pale skin, it may be more than simple tiredness. It can be one of the possible signs of anemia.
When fatigue becomes a warning sign
In anemia, the body may not have enough healthy red blood cells or hemoglobin to carry oxygen to tissues. Because of this, a person may feel low on energy even during normal daily activity.
Symptoms worth paying attention to
- constant weakness and getting tired quickly;
- shortness of breath while walking, climbing stairs or doing light activity;
- dizziness, lightheadedness or feeling close to fainting;
- pale skin, cold hands and feet;
- fast or irregular heartbeat;
- headaches and reduced concentration;
- brittle nails or unusual cravings for ice or non-food substances.
Why anemia may develop
Anemia can have different causes: iron deficiency, vitamin B12 or folate deficiency, chronic inflammation, blood loss, blood disorders, cancer or side effects of treatment.
If fatigue appears during anticancer therapy, it is important to discuss it with a doctor. Some treatments can affect the bone marrow and reduce red blood cell production. In such cases, the related sections hematology, oncology and supportive medications may be relevant for reviewing available directions.
Tests that may help clarify the cause
| Test | Why it is checked |
|---|---|
| Complete blood count | Shows hemoglobin, red blood cells and other important blood markers. |
| Ferritin and serum iron | Help assess iron stores in the body. |
| Vitamin B12 and folate | Help rule out vitamin-deficiency anemia. |
| Additional tests | May be ordered by a doctor if chronic disease, blood loss or treatment complications are suspected. |
Anemia and cancer treatment
In people with cancer, weakness may be related not only to the disease itself but also to treatment. Chemotherapy, radiation therapy and some targeted treatments can affect blood counts. That is why pronounced fatigue should not be ignored. It is better to inform your doctor and check blood tests.
