Most of the time tiredness is connected with lifestyle and work surrounding. But sometimes, it also occurs due to a disease or the intake of certain medications.
Which diseases and medications cause tiredness?
- Infections: Viral or bacterial infections may cause tiredness and exhaustion. For example when suffering under a flu or a cold, our immune system works at full speed to fight against the pathogens. This may lead to tiredness.
- Metabolic diseases: With diabetes or hypothyroidism often tiredness arises.
- Anemia: During menstruation women often suffer under anemia due to iron deficiency. Iron is an important part of hemoglobin (molecule for oxygen transport). Now, when losing iron fewer oxygen is brought into the cells, the tissue and the brain. Low-iron diet, pregnancy or blood loss after an injury or surgery are further possible reasons for anemia.
- Sleep apnoea: The nightly breathing stops constantly interrupt sleep. Therefore, people concerned often feel very tired during the day.
- Mental illness: Tiredness also often occurs when suffering under depressions or anxiety disorders. If low spirits and tiredness occur during the cold months of autumn and winter this mostly is an indication for seasonal dependent depression (SAD).
- Cancer: Cancerous diseases like for example blood cancer (leukemia) or lymph gland cancer (lymphoma) and cancer therapies (for example irradiation, chemotherapy) also may cause tiredness. This special form of tiredness is called tumor-related fatigue and is not improving with sufficient sleep and physical rest.
- Medication: One possible side effect of drugs like for example antidepressants, medicines against high blood pressure, antihistamines or neuroleptics is tiredness.
