Low blood pressure

 

Low blood pressure (hypotension) happens when your blood pressure drops below 90/60 mmHg, though symptoms matter more than the exact numbers. Sometimes it’s harmless, but if it’s frequent or causing symptoms, it needs attention.

Common Causes of Low Blood Pressure

1. Dehydration – Not drinking enough water or losing fluids through sweating, vomiting, or diarrhea.
2. Poor nutrition – Lack of electrolytes, salt, or key nutrients like B12 or iron.
3. Medications – Some blood pressure meds, antidepressants, or diuretics can lower BP too much.
4. Hormonal issues – Thyroid, adrenal, or other hormone imbalances.
5. Heart problems – Irregular heartbeat or heart failure in rare cases.
6. Rapid position changes – Known as postural hypotension, standing up too fast can drop your pressure.
7. Pregnancy – Blood pressure naturally runs lower during pregnancy.

Symptoms to Watch

• Dizziness or lightheadedness
• Blurry vision
• Fainting 
• Weakness or fatigue
• Nausea
• Confusion or difficulty concentrating

What You Can Do

Immediate relief:

• Sit or lie down and elevate your legs
• Drink water or an electrolyte drink
• Eat a small salty snack if your doctor hasn’t restricted salt

Daily habits:

• Stay well hydrated (2–3 L of water a day)
• Eat balanced meals with enough protein and complex carbs
• Avoid standing up too quickly
• Wear compression stockings if your doctor recommends them
• Exercise gently to improve circulation

When to See a Doctor

• If you faint often or feel extremely weak
• If you have chest pain, shortness of breath, or confusion
• If your low blood pressure started suddenly
• If you’re on medication that may be lowering your pressure too much
