Identify the cause of low blood pressure for early prevention

Recognizing the causes of low blood pressure is important to know how to relieve symptoms and prevent this condition.

Causes of your blood pressure dropping to low levels can include things like dehydration, medication side effects, underlying health problems like heart disease, hormonal disorders, mental conditions menstruation and pregnancy. Identifying the root cause of low blood pressure can help you find more effective treatment.

Blood pressure that ranges from 90/60 mmHg to 120/80 mmHg depending on age is a normal, healthy blood pressure. When your blood pressure is below 90/60 mmHg, it is considered hypotension. At this time, the brain and other organs in the body may not receive enough blood to function properly and cause symptoms that affect the person.

What causes low blood pressure? Below you will learn about the causes of low blood pressure and how to prevent it accordingly!

Causes of low blood pressure

There are three main types of hypotension, orthostatic hypotension, nerve-mediated hypotension, and severe shock-related hypotension, each of which has different underlying causes. Also, structural heart problems and risk factors that will contribute to low blood pressure include:

Orthostatic hypotension

Orthostatic hypotension is one of the most common conditions of low blood pressure, also known as orthostatic hypotension. This phenomenon occurs when blood pressure drops rapidly during a change in body position, usually when changing from a sitting position to a standing position. When this occurs, the person may experience signs of low blood pressure such as dizziness, blurred vision, and fainting.

Normally, when you are sitting up in a lying position, nerve receptors signal and the central nervous system responds by stimulating the muscles in the artery walls to contract to increase blood pressure, causing the heart to contract. you beat faster. This is to keep blood from flowing down the lower body.

In orthostatic hypotension, physiological processes in the body do not happen as they should, causing blood flow to your brain to decrease, blood pressure to drop, and symptoms of dizziness.

Causes of orthostatic hypotension may include:

  • Pregnant
  • Anemia
  • High age
  • Heart problems
  • Pulmonary embolism
  • Diabetes
  • Severe infection
  • Thyroid disorders
  • Low blood sugar
  • Dehydration (may be due to sweating, not drinking enough water, vomiting or diarrhea)
  • Nervous system disorders including Parkinson's disease, Lewy body dementia, multiple system atrophy, Guillain-Barré syndrome

Orthostatic hypotension can also be a side effect of certain medications, especially diuretics or medications for high blood pressure such as beta-blockers. Certain medications used to treat erectile dysfunction and psychiatric disorders also carry a risk of low blood pressure. You can also experience orthostatic hypotension simply from being outside in the heat or being inactive for a long time.

Nerve-mediated hypotension

Nervous system problems, especially autonomic nervous system disorders, including orthostatic tachycardia syndrome (POTS) and vagal syncope can cause hypotension. Emotional stress can also be a trigger for neurally mediated hypotension.

Neurally mediated hypotension occurs when there is poor communication between your brain and heart and sends the wrong signal that your blood pressure is high. This slows down the heart and lowers blood pressure.

Nerve damage that can result from diabetes such as autonomic (autonomic) neuropathy and peripheral neuropathy can also affect blood pressure regulation.

Severe hypotension associated with shock

Some causes of severe shock-related hypotension can lead to orthostatic hypotension. At this time, the blood pressure dropped much more severely than before and showed no signs of returning to normal.

Causes of hypotensive shock include:

  • Heavy bleeding (internal or external)
  • Septic shock due to infection or toxins
  • Cardiogenic shock due to heart attack, arrhythmia or pulmonary embolism
  • Vasodilating shock in head trauma, liver failure, poisoning or anaphylaxis
  • Severe loss of body fluids from diarrhea, burns, or overuse of diuretics

For some people, low blood pressure doesn't pose a serious problem, unless it happens suddenly or causes other symptoms. In fact, when you have low blood pressure, you reduce your risk of heart disease, heart attack, or stroke.

Causes of low blood pressure due to heart problems

Sometimes blood pressure can be affected by the function or structure of the heart. This can lead to orthostatic hypotension or, in severe cases, cardiogenic shock. Heart problems can cause low blood pressure, a decrease in the heart's ability to work, and reduced blood flow to the body.

The buildup of plaque in the arteries with aging can narrow blood vessels and reduce blood flow to your heart and brain. This can also contribute to low blood pressure.

Risk factors for low blood pressure

Blood pressure can be affected by other factors, including your diet, exercise, and age. Some risk factors that can cause low blood pressure include:

  • Nutritional deficiencies: A deficiency in essential nutrients, such as folic acid or iron, can reduce red blood cell counts or hemoglobin levels, leading to anemia.
  • Changes in blood sugar: Changes in blood sugar, like diabetes, can lead to low blood pressure.
  • Eating habits: Some older patients, especially those with high blood pressure, may experience a drop in blood pressure after taking a large meal.
  • Dehydration: Vomiting, diarrhea for a long time or due to exercise, sweating and heatstroke if not replenished in time, can lead to a drop in blood pressure.

How to prevent the causes of low blood pressure

Here are some ways that can help you reduce or prevent symptoms of low blood pressure:

  • Drink plenty of water and limit alcohol intake: Alcohol dehydrates and can lower blood pressure, even if you drink in moderation. On the other hand, water helps you fight dehydration and increase blood volume.
  • Build a healthy diet: To get all the nutrients you need for good health, you need to focus on getting a variety of foods, including whole grains, fruits, vegetables, chicken, and fish. .
  • Pay attention to sitting position: You should gently move slowly from lying to standing position, and at the same time limit sitting with legs crossed. For example, before you wake up in the morning, take a few deep breaths and then slowly sit up.
  • Eat smaller meals and cut carbs: To help prevent a sharp drop in blood pressure after meals, eat small portions each day and limit carbohydrate-rich foods like potatoes, rice, pasta, and bread.

Your doctor may also recommend that you drink caffeinated coffee or tea with meals to temporarily raise blood pressure. However, caffeine can cause other health problems if used incorrectly, so you should consult your doctor before using it.
