Ideally, everyone should have a blood test at least once a year, because prevention is very important in the development of diseases. Small irregularities often appear in routine blood tests, for example in vitamin or iron levels, which can then be easily brought back into balance. In reality, however, preventive blood tests are rarely done, so most illnesses are detected only at the moment when we suffer from one of the symptoms listed below. If you notice any of these signs in yourself, ask your doctor for blood tests without delay.
Abnormal fatigue, paleness, headache
Many illnesses can be the cause of a constant feeling of weakness. In spring this is to some extent a natural state, because the body’s vitamin stores thin out after a long winter. Fatigue is often caused by iron deficiency. If supplementation does not help, visit a doctor.
Headaches or even migraines can occasionally be considered natural, but persistent pains are already a good reason to take blood samples, as this problem can signal a number of more serious conditions.
Vision problems, heavy menstrual bleeding and blood in stool or urine
Blurred or double vision often appears with diabetes, so if this problem troubles you, go to a laboratory; blood samples can determine a certain blood sugar level. Fluctuations in blood pressure can also worsen vision.
Abnormally heavy menstruation can easily lead to anemia, which is accompanied by fatigue, dizziness, paleness. Hormonal disorders underlying excessive bleeding can also be easily detected by a blood test. If you find blood in your urine or stool, hurry to see a doctor. Bloody urine usually indicates a urinary tract infection. Blood in the stool can represent a range of more serious problems, from simple hemorrhoids to colon cancer, so a blood test is a very important part of the examination. Other conditions that require blood tests are:
- tinnitus,
- dizziness,
- recurrent loss of consciousness.
