Low blood pressure, also called hypotension, happens when blood pressure becomes lower than normal levels. In some people, low blood pressure may not cause problems, but in others it can lead to weakness, dizziness, or fainting.
Blood pressure helps move oxygen and nutrients throughout the body. When pressure becomes too low, organs may not receive enough blood flow.

| Signs and Symptoms of Low Blood Pressure You Should Know |
What Is Considered Low Blood Pressure?
Blood pressure below 90/60 mmHg is generally considered low.
However, some healthy people naturally have lower blood pressure without symptoms.
Common Signs of Low Blood Pressure
1. Dizziness
Feeling dizzy or lightheaded is one of the most common symptoms, especially when standing up quickly.
2. Fainting
Very low blood pressure can reduce blood flow to the brain and cause fainting.
3. Blurred Vision
Some people may notice temporary blurry vision during episodes of low blood pressure.
4. Fatigue
Low blood pressure may cause weakness and tiredness because the body is not getting enough oxygen-rich blood.
5. Cold Hands and Feet
Poor circulation may make the hands and feet feel cold.
6. Nausea
Some people experience nausea or stomach discomfort during sudden blood pressure drops.
7. Fast or Shallow Breathing
The body may react to low blood flow by increasing breathing rate.
Causes of Low Blood Pressure
Many conditions and situations can lead to hypotension, including:
Dehydration
Blood loss
Long periods without eating
Certain medicines
Heart problems
Severe infections
Pregnancy
Nutritional deficiencies
Types of Low Blood Pressure
Orthostatic Hypotension
This happens when blood pressure suddenly drops after standing up.
Postprandial Hypotension
Some older adults may experience low blood pressure after eating meals.

Dangerously low blood pressure caused by shock, infection, or major blood loss needs emergency treatment.
How to Manage Mild Low Blood Pressure
Drink Enough Water
Staying hydrated helps maintain healthy blood circulation.
