What Are the Causes of Diarrhea, Fatigue, and Low Blood Pressure?

Based on the described clinical scenario, cardiac disease is the most likely underlying cause, although other factors—such as dehydration and electrolyte imbalances secondary to chronic diarrhea—must also be considered. Prompt evaluation at a reputable, public Grade A-3 hospital’s Department of Cardiology or General Internal Medicine is strongly recommended to determine the exact cause and establish a definitive diagnosis. A specialist will then initiate appropriate, etiology- and condition-specific treatment to prevent disease progression or complications.
