Low blood pressure, or hypotension, is a condition where an individual's blood pressure falls below 90/60 mm Hg. While it often presents asymptomatically, low blood pressure can be indicative of underlying health issues, particularly in older people, and can lead to reduced blood flow to the heart, brain, and other vital organs. In emergency situations, medical professionals may administer drugs such as Norepinephrine bitartrate (Levophed), which acts like adrenaline, causing blood vessels to constrict and support blood pressure. However, this may not always be the best course of action, as it can put a strain on the heart. Instead, natural remedies and lifestyle changes are often recommended to manage low blood pressure. These include increasing salt and water intake, wearing compression stockings, and reducing alcohol consumption.

What You'll Learn
Increase sodium intake
While increasing sodium intake can raise blood pressure, it is not recommended as a means to increase blood pressure in a hospital setting. This is because sodium intake should be carefully monitored and controlled by medical professionals to maintain a patient's health.
However, if a doctor advises you to increase your sodium intake, it is important to understand that sodium is a component of salt, and eating foods with high salt content will increase your sodium intake. The recommended daily sodium intake is between 1500 and 2300 milligrams, with a minimum daily requirement of 500 milligrams. To increase sodium intake, one can consume table salt, which is about 40% sodium.
When dining out, be aware that restaurant food often contains high levels of sodium. To increase sodium intake, simply adding salt to your dish or using a salt shaker can effectively raise your sodium levels.
Additionally, processed and packaged foods often contain high amounts of sodium. Canned and frozen foods, soups, tomato sauce, condiments, and canned goods can contribute significantly to sodium intake. When purchasing these items, look for those labeled ""reduced sodium" or "less sodium," as they may contain lower amounts of sodium compared to regular products.
It is important to note that while increasing sodium intake can influence blood pressure, it should be done under medical supervision and within safe limits. Excessive sodium intake can have adverse health effects, and it is crucial to prioritize overall health and well-being.

Compression stockings
Research has shown that compression stockings can be effective in treating orthostatic hypotension and reducing the incidence of hypotension in patients undergoing surgery in the beach-chair position. One study found that wearing compression stockings significantly elevated systolic blood pressure in female subjects with hypotension when in a supine position. However, no significant difference in blood pressure was found between the control and compression stocking groups in the beach-chair position.

Medication: Norepinephrine bitartrate
Norepinephrine bitartrate, also known as Levophed, is a medication used to treat severe, acute, and life-threatening cases of low blood pressure (hypotension). It is often used during or after CPR (cardiopulmonary resuscitation) and in other emergency situations.
Norepinephrine is a sympathomimetic amine, structurally similar to adrenaline, and acts as a vasoconstrictor. It narrows the blood vessels, supporting blood pressure. This medication is administered through an intravenous infusion or injection, and it is supplied in a sterile, colorless solution in single-dose amber glass vials.
As with any medication, there are potential side effects and risks associated with the use of norepinephrine bitartrate. Some common side effects include allergic reactions such as skin rash, itching, hives, and swelling of the face, lips, tongue, or throat. It can also cause heart rhythm changes, including a fast or irregular heartbeat, dizziness, chest pain, and trouble breathing.
It is important to carefully monitor patients receiving this medication and report any side effects to the care team. Norepinephrine bitartrate may also interact with other medications, including blood pressure medications, MAO inhibitors, and antidepressants. Therefore, it is crucial to inform your doctor about all medications you are currently taking.
Additionally, this medication should be used with caution in patients with certain medical conditions, such as asthma, blood clots, hypertension (high blood pressure), hypoxia (low oxygen in the blood), and hypovolemia (low blood volume). It may also cause tissue ischemia (low blood supply to the tissues), which can lead to gangrene.

Address nutritional deficiencies
Addressing nutritional deficiencies is an important step in managing low blood pressure. A healthy, balanced diet is key to maintaining overall health and ensuring adequate blood flow and oxygen supply to vital organs.
Folate and vitamin B12 deficiencies, for example, can cause anemia, which may contribute to low blood pressure levels. Therefore, it is important to include foods rich in these vitamins, such as leafy greens, legumes, and animal products. Additionally, sodium (salt) intake can be moderately increased as it helps raise blood pressure. However, it is crucial to monitor the amount of salt added to the diet to prevent excessive sodium consumption, which can lead to heart disease.
For those with diabetes, managing blood sugar levels is essential. Volume depletion can occur due to increased urination caused by high blood sugar. A balanced diet and regular monitoring of blood sugar levels can help prevent this. Similarly, hypothyroidism, or an underactive thyroid, can lead to low blood pressure. In such cases, a doctor may recommend a nutrition plan to boost thyroid function.
It is important to note that dietary changes should be made under the guidance of a healthcare professional to ensure they are tailored to the individual's specific needs and do not interfere with any medications or health conditions.

Avoid large meals
If you are looking to increase your blood pressure, it is important to consult a healthcare professional or a dietitian to ensure that your nutritional needs are being met. They can advise you on the best course of action, which may include making changes to your diet.
One recommendation that is often made is to avoid large meals. Eating large meals can cause a more dramatic drop in blood pressure as your body has to work harder to digest them. Instead, it is suggested to eat small meals more frequently throughout the day. This can help to raise your blood pressure by preventing a significant drop after eating.
It is also important to stay hydrated, as dehydration can lead to a decrease in blood volume, causing blood pressure to drop. Drinking water frequently throughout the day and limiting time in hot environments like saunas, steam rooms, and hot tubs can help maintain hydration levels and support healthy blood pressure.
In addition to portion size, the types of food you eat can also impact your blood pressure. It is generally recommended to limit or avoid foods high in sodium, added sugars, and saturated fats. This includes processed foods, fast food, and canned goods, which often contain high levels of salt and preservatives. Instead, opt for fresh, whole foods like fruits and vegetables, and wholegrains. These provide essential nutrients like potassium and magnesium, which are beneficial for maintaining healthy blood pressure.
While making dietary changes can be helpful, it is important to remember that increasing blood pressure should be done under medical supervision, especially if you have any underlying health conditions or are taking medications.

Frequently asked questions
Some natural ways to increase blood pressure include drinking more water, wearing compression stockings, and eating smaller meals. People with low blood pressure may also benefit from eating more salt, but it is important not to consume too much.
Some medications that can help raise blood pressure include norepinephrine bitartrate (Levophed), fludrocortisone, and midodrine. BiPAP machines can also be used, but they may lower blood pressure at first as the body gets used to them.
Some symptoms of low blood pressure include blurred vision, confusion, dizziness, fainting, feeling cold, nausea, thirst, and fatigue. Low blood pressure can also lead to more serious symptoms such as shock and organ failure.
Increasing blood pressure medications at hospital discharge may pose a greater risk of falls, fainting, and acute kidney injury, especially in older patients. A study found that veterans discharged with intensified antihypertensives had a significantly higher risk of readmission and serious adverse events within 30 days.
