[/INST] Hello! Welcome and thank you for asking on Chat Doctor! Your symptoms could be related to blood pressure Chat Doctor.  Are you taking any beta blockers? They can cause chronic fatigue and low physical performance. But, I would also recommend consulting with your attending physician for a careful physical exam and some tests to investigate for other possible underlying causes: - a chest X-ray study- an arterial blood gas analysis-complete blood count for anemia-thyroid hormone levels for thyroid dysfunction- blood electrolytes- kidney and liver function tests-blood electrolytes. If all these tests result normal, I would recommend performing a multi latency sleep test to investigate for possible sleep apnea. Hope to have been helpful! Wishing all the best,  </s>
