overview
Low blood pressure seems like a good thing, and some people are fine with it. However, in many people, abnormally low blood pressure (hypotension) can cause dizziness and fainting. In severe cases, low blood pressure can be life threatening.
A blood pressure below 90 millimeters of mercury (mm Hg) for the upper number (systolic) or 60 mm Hg for the lower number (diastolic) is generally considered to be low blood pressure.
Hypotension can range from dehydration to serious illness. It is important to know what is causing your low blood pressure in order for it to be treated.
symptoms
In some people, low blood pressure indicates an underlying problem, especially if it suddenly decreases or is accompanied by signs and symptoms, such as:
- Dizziness or lightheadedness
- Faint
- Blurred vision or discoloration
- nausea
- Tired
- Little concentration
The reasons
Blood pressure is a measure of the pressure in your arteries during the active and resting phases of each heartbeat.
- Systolic pressure. The highest number in a blood pressure reading is the pressure your heart creates as it pumps blood through your arteries to the rest of your body.
- Diastolic pressure. The bottom number on a blood pressure reading refers to the pressure in your arteries when your heart is at rest between beats.
- Current guidelines identify normal blood pressure less than 120/80 mm Hg.
Blood pressure varies throughout the day depending on:
- Body position
- Breathing rhythm
- Stress level
- Physical condition
- The medications you are taking
- What you eat and drink
- Time of day
Risk factors
Low blood pressure (hypotension) can happen to anyone, although some types of hypotension are more common depending on age or other factors:
- Age. Loss of blood pressure while standing or after eating occurs mainly in adults over 65 years of age. Neuron-mediated hypotension primarily affects children and young adults.
- Medication. People who take certain medications, such as high blood pressure medications like alpha blockers, are at higher risk for low blood pressure.
- Some diseases. Parkinson’s, diabetes, and some heart conditions put you at increased risk of low blood pressure. Low blood pressure (hypotension) Treatment in Hyderabad
