For some people, low blood pressure (hypotension) is the norm. There are a few things that may help raise your blood pressure quickly.

A sudden drop in blood pressure can make you feel light-headed, dizzy, or faint. In some cases, it can signal a health problem or a medical emergency. If it's a common occurrence, you may need to take steps to help prevent these episodes.

This article discusses how to increase blood pressure, when to see a healthcare provider, and when low blood pressure requires emergency care.

12 Ways to Increase Blood Pressure

Low blood pressure doesn't necessarily require treatment. However, there are some home remedies and lifestyle tweaks if your blood pressure is low.

Without Medication

Blood pressure that drops when you stand from a sitting or lying down position is called postural or orthostatic hypotension. What may help at the moment include:

• Performing a counter-maneuver: Making a fist, crossing your legs, or clenching your buttocks may improve blood flow and raise blood pressure.
• Having a cup of coffee: Caffeinated coffee can cause a rapid rise in blood pressure. The effect is generally quick and levels off within a few hours.
• Waiting it out: When you feel light-headed or dizzy, sit down and wait a few minutes. Then, get up slowly, bracing yourself if necessary.
  

Doing the following can help cut down on low blood pressure episodes:

• Drinking water before meals: Try drinking 12 to 18 ounces of water about 15 minutes before eating to help prevent a blood pressure drop.
• Hydrating throughout the day: Dehydration can sometimes lead to a drop in blood pressure. Aim for six to eight glasses of water or low-calorie drinks daily unless your healthcare provider advises limiting fluids.
• Eating smaller meals: Smaller meals are less likely to cause a drop in blood pressure. You can switch from three meals daily to six or seven smaller ones.
• Resting after eating: Your blood pressure may hit its lowest point a half hour to an hour after a meal. Sit or lie down during this time to avoid light-headedness. Get up slowly and brace yourself if you feel dizzy.
• Getting physical: Avoid standing or sitting in one position for too long. Lack of exercise can worsen symptoms of low blood pressure.
• Wearing compression stockings: Compression stockings may increase blood flow and reduce symptoms.
• Raising the head of your bed: If you tend to get dizzy when you wake up in the morning, try raising the head of the bed or using a wedge pillow while you sleep.
  

With Medication 

Most people won't need medication to increase blood pressure. A few lifestyle adjustments and treating any underlying cause are usually sufficient. Some things a healthcare provider may do include:

• Review current medications: Certain medications, such as opioids (narcotics) and some antidepressants, can lower blood pressure. Ask your provider if you need adjustments or alternatives.
• Prescribe medicines: Drugs that can help treat low blood pressure include Florinef (fludrocortisone), which makes the kidneys retain water and boosts blood volume. Miododrine works by tightening blood vessels.
  

What Foods Increase Blood Pressure?

Rapidly digested carbohydrates can lead to a fall in blood pressure. These include foods made with highly refined flour, such as white bread. Also, white rice, potatoes, and sugary drinks. Try to replace these with slowly digested foods that may help keep your blood pressure up after eating. These include:

• Whole grains
• Beans
• Protein
• Healthy oils

Deficiencies in vitamin B12 and folate can cause anemia, leading to low blood pressure. Dietary sources of vitamin B12 include:

• Fish, meat, poultry
• Eggs
• Dairy products
• Fortified breakfast cereals and nutritional yeasts

Foods that contain folate are:

• Spinach, asparagus, brussels sprouts
• Liver, meat, poultry
• Fruits and fruit juices
• Nuts, beans, peas
• Seafood
• Eggs
• Dairy products
• Grains

You can also try adding a little more salt to your diet. But dietary salt can affect other health conditions, so you might want to check with your provider to ensure this is safe for you.

What Is a Dangerously Low Blood Pressure?

There's no specific number at which daily blood pressure readings are too low. But unusually low blood pressure can prevent oxygen from getting to vital organs.

This can be due to serious problems such as blood loss or a heart condition. Low blood pressure can lead to shock, a life-threatening emergency.

Monitoring Blood Pressure At Home 

An automatic cuff-style bicep monitor is recommended for at-home monitoring. Make sure it has been validated and is the correct cuff size. A few tips to keep in mind include:

• Take your blood pressure at the same time daily.
• Avoid smoking, caffeine, and exercise for 30 minutes before taking your blood pressure. Sit calmly for five minutes before starting.
• Sit with your back straight, feet flat on the floor, and legs uncrossed.
• Support your arm on a flat surface. The upper arm should be at heart level.
• Place the bottom of the cuff just above the bend of the elbow. Don't put the cuff over sleeves.

One reading represents your blood pressure at that moment in time. Keep a record of your daily readings to have a better picture of your normal blood pressure. Let your provider know if you have multiple readings that are not within the normal range.

Summary

A quick drop in blood pressure can cause light-headedness, dizziness, and fainting. You can do a few things to bring your blood pressure back up quickly. And you can take steps to help prevent symptoms.

Low blood pressure doesn't always require medical treatment. However, you may need treatment for any underlying conditions contributing to low blood pressure. In some cases, low blood pressure indicates a serious and even life-threatening problem, such as heart disease or blood loss.
