Hello,
Dizziness and easy fatigability are seen in conditions like heart failure,
myocardial infarction, angina due to clogged vessels, hypothyroidism, deep
venous thrombosis, usage of various medications like anti-depressants,
transient ischemic attack or mini stroke, stroke (associated with other symptoms like weakness of limbs),
peripheral neuropathy leading to
orthostatic hypotension or anemia.
You need a detailed evaluation by history taking, clinical examination and few tests like complete blood picture, ECG, 2D echocardiography, examination of nervous system if necessary MRI brain, kidney and liver function tests. Please consult a physician for specific diagnosis and appropriate treatment.
Take care. Hope I have answered your question. Let me know if I can assist you further.
