7 Hidden Causes of Low Blood Pressure

Definition of Hypotension: Hypotension is defined as low blood pressure—systolic pressure under 90 mm Hg or diastolic pressure under 60 mm Hg. Prevalence: Approximately 10% of the population experiences chronic hypotension. Heart Disease Connection: There’s a strong correlation between hypotension and underlying heart diseases, making early detection critical to prevent complications. Types of Hypotension: We covered several types: Chronic: persistently low blood pressure Acute: sudden drop in blood pressure Orthostatic: occurs upon standing Shock-related: due to severe conditions like septic shock Postprandial: occurring after a large meal Orthostatic Hypotension: This is the most common scenario, where blood pools in the legs upon standing, causing dizziness or fainting within three minutes. Primary Symptoms: Key signs include dizziness, fainting (syncope), fatigue, nausea, blurred vision, difficulty concentrating, and cold, clammy, pale skin. Dehydration as a Cause: Dehydration is a leading cause, especially in older adults, physically active individuals, and children who might not recognize thirst signals. Impact of Medications: Certain medications—like beta blockers, ACE inhibitors, and diuretics—can lead to hypotension, particularly in the elderly due to altered drug metabolism. Endocrine and Metabolic Factors: Endocrine issues such as hypothyroidism, hyperthyroidism (especially with treatment), Addison’s disease, and hypoglycemia are important contributors. Neurally Mediated & Shock-related Causes: Neurally mediated hypotension, often triggered by prolonged standing, stress, or pain, and shock (especially septic shock) are significant causes, with shock having a high mortality rate if untreated.
