Low blood pressure (hypotension) can often be managed with simple steps at home, but it can also be dangerous if symptoms are severe or sudden. If numbers are very low or you feel very unwell, you need urgent medical help.

First: When it’s an emergency

If you have low blood pressure and ANY of these, call emergency services or go to ER/AE immediately:

  • Fainting or near-fainting.
  • Chest pain, shortness of breath, or a racing/irregular heartbeat.
  • Confusion, trouble speaking, or difficulty staying awake.
  • Skin that is cold, pale, or sweaty, with fast, weak pulse.
  • Blood pressure around or below about 90/60 with strong symptoms (dizziness, collapse).

These can be signs of shock, heart problems, severe infection, internal bleeding, or a serious reaction to medicines.

Quick things to do right away

If you suddenly feel light-headed, weak, or like you might faint:

  1. Lie down safely
    • Lie flat on your back and, if possible, raise your legs on a pillow, chair, or wall.
    • If you can’t lie down, sit and put your head between your knees.
    • Stay still until the dizziness passes, then get up very slowly.
  2. Loosen tight clothes
    • Loosen belts, tight collars, or anything that might restrict blood flow or breathing.
  3. Drink fluids (if you’re awake and can swallow)
    • Sip water or an oral rehydration/electrolyte drink.
    • Avoid alcohol; it can make blood pressure drop further.
  4. Stay cool but not cold
    • Overheating (hot showers, saunas, hot weather) often worsens low blood pressure.
    • Move to a cooler place if you feel faint.

If your symptoms don’t improve within a few minutes, or get worse, seek urgent medical care.

What to do for mild or recurring low blood pressure

If you often have low readings or feel dizzy on standing, talk to a doctor; meanwhile, these strategies are commonly recommended:

1. Adjust how you move

  • Get up slowly from bed: first sit on the edge for a minute, then stand.
  • Avoid sudden posture changes (quickly bending down or standing up).
  • Do not stand or sit perfectly still for very long; move your legs, shift weight, or walk a bit.

2. Hydrate and eat smart

  • Drink enough water across the day; dehydration is a frequent trigger.
  • Eat smaller, more frequent meals rather than very large ones, which can drop blood pressure after eating.
  • Some people are advised by their doctor to slightly increase salt; never make big salt changes without medical guidance, especially if you have heart or kidney issues.

3. Clothing and body positioning

  • Ask your doctor if compression stockings or an abdominal binder are appropriate; they help keep blood from pooling in your legs.
  • Avoid sitting with legs tightly crossed for long periods; it can affect circulation.
  • In hot weather, use fans, light clothing, and avoid long hot baths or showers.

Common causes to think about

These don’t replace a diagnosis, but they can help you and your doctor figure things out:

  • Dehydration from not drinking enough, diarrhea, vomiting, fever, or heavy sweating.
  • Medications (for blood pressure, heart, depression, Parkinson’s, diuretics, and others).
  • Standing up quickly after sitting or lying down (orthostatic hypotension).
  • Hormonal or heart conditions, severe infection, or blood loss.

If hypotension is new for you, worse than usual, or you’re on multiple medications, you should book a medical review soon.

How doctors often help

Depending on cause and severity, a clinician may:

  • Review and adjust your medications.
  • Check blood tests, heart rhythm, and sometimes do a tilt-table test.
  • Recommend lifestyle changes (fluids, meal pattern, compression garments, exercise).
  • In some cases, prescribe medication to help raise or stabilize blood pressure.

A quick example

Imagine someone who feels dizzy every time they stand:

  • They start sitting up slowly in bed, drinking a glass of water in the morning, and wearing compression stockings.
  • They switch to smaller, more frequent meals and increase daily walking without overexertion.
  • With a doctor’s review of their medications, the dizzy spells become rare and less intense.
