About Blood Pressure and its causes?

Let’s learn first what is blood pressure; the heart, as we are all aware, pumps blood around the body like a pump. As a result, a certain pressure is applied to the blood as it passes through the veins. The pressure will come, go, and come again if you place a finger on the vein in your wrist. Blood will flow easily through your veins and your blood pressure will be within the normal range if your veins are healthy. Your blood pressure will rise if you have damaged or ill-maintained veins.

As an example, suppose the pipe that delivers water to your lawn becomes clogged. When the mouth is slightly narrowed or pressed, the same pressure comes from the back as before, but the pressure is higher in the front. If the veins are damaged or narrowed, the heart is also put under strain, and the blood is forced by the heart. It must be purged. High pressure also causes damage to veins. A decrease in blood supply to the body can cause a variety of problems, including heart failure, kidney failure, and stroke.

The function of blood pressure in the body

Blood pressure is the force of blood against the walls of the arteries as it is pumped around the body by the heart. It is an important measure of cardiovascular health, as it can indicate how hard the heart is working to pump blood and whether the arteries are narrowed or blocked.

The blood pressure reading is given as two numbers: systolic blood pressure and diastolic blood pressure. Systolic blood pressure is the pressure in the arteries when the heart beats and pumps out blood, while diastolic blood pressure is the pressure in the arteries when the heart is resting between beats.

The body needs a certain amount of blood pressure to maintain proper circulation and deliver oxygen and nutrients to the cells. However, if the blood pressure is too high, it can put extra strain on the heart and blood vessels, increasing the risk of health problems such as heart attack, stroke, and kidney damage. On the other hand, if the blood pressure is too low, it can cause dizziness, fainting, and other problems.

It is important to maintain normal blood pressure levels to help ensure good cardiovascular health. This can be achieved through a combination of healthy lifestyle habits such as eating a healthy diet, getting regular exercise, and managing stress, as well as, in some cases, taking medication as prescribed by a healthcare provider.

Normal blood pressure reading

A normal blood pressure reading is less than 120/80 mmHg. However, it is important to note that normal blood pressure can vary slightly from person to person, and can also change throughout the day. It is generally recommended to have blood pressure measured when you are in a relaxed, seated position after resting for a few minutes.

High blood pressure (HBP) chart 

Here is a chart that shows the categories of blood pressure based on the results of a blood pressure measurement:

Category Systolic (mmHg) Diastolic (mmHg)
Normal Less than 120 Less than 80
Prehypertension 120-139 80-89
Stage 1 hypertension 140-159 90-99
Stage 2 hypertension 160 or higher 100 or higher

It is important to note that blood pressure can vary throughout the day and can be affected by factors such as stress, caffeine, and physical activity. It is generally recommended to have your blood pressure measured when you are in a relaxed, seated position after resting for a few minutes. If you have consistently high blood pressure readings, it is important to discuss this with your healthcare provider, as high blood pressure can increase your risk of serious health problems such as heart attack and stroke.

It is also possible to have high blood pressure due to an underlying health condition, such as kidney disease or sleep apnea. If you have high blood pressure, it is important to work with your healthcare provider to determine the cause and find the best treatment plan for you.

Why everyone has a different reading of blood pressure?

Another question is whether some people have high blood pressure all the time, while others have normal blood pressure but their blood pressure rises due to walking or some other problem. So the reason for this is that those whose veins are more damaged or closed, their blood pressure is always high, whereas scientists explain that in the old days when man was not advanced, in case of any danger, he would either fight or run away to save his life. “Fight or Flight Syndrome” is the term for this.

In such a case, the human heart begins to pump blood at high pressure, and enzymes are produced in the body, causing the blood to thicken. Nature did all of this to help man fight or run faster to save his life. That man is now at a developed age, and he no longer has to deal with these kinds of problems, but he is now dealing with new types of problems. It goes without saying that the blood pressure is elevated.

If veins are damaged or closed

In contrast, people whose veins are damaged or are closed, do not provide a way for more blood to flow, so as a result, their blood pressure increases, and then gradually they start experiencing chest pain, i.e. Angina, shortness of breath, heart failure, nausea, etc. A young man with healthy veins does not have a problem with blood pressure because his veins open to higher blood pressure and allow more blood to pass through.

Reasons for having HBP

There are many possible causes of high blood pressure (also known as hypertension). Some people may have high blood pressure due to genetics, while others may develop it due to lifestyle factors such as poor diet, lack of physical activity, or stress. Other factors that can contribute to high blood pressure include:

  • Age: As you get older, your blood vessels become less flexible and your heart may become less efficient at pumping blood, which can lead to high blood pressure.
  • Weight: Being overweight or obese can increase your risk of high blood pressure.
  • Alcohol consumption: Drinking too much alcohol can raise your blood pressure.
  • Smoking: Smoking can damage your blood vessels and increase your risk of high blood pressure.
  • Certain medications: Some medications, such as birth control pills and decongestants, can increase blood pressure.

Tips for preventing high blood pressure

There are several lifestyle habits that can help prevent high blood pressure (also known as hypertension) or help lower high blood pressure:

  1. Maintain a healthy weight: Being overweight or obese can increase your risk of high blood pressure. Losing excess weight can help lower your blood pressure.
  2. Eat a healthy diet: A diet rich in fruits, vegetables, and whole grains and low in salt, saturated and trans fats, and added sugars can help lower blood pressure.
  3. Get regular exercise: Aim for at least 30 minutes of moderate-intensity exercise, such as brisk walking, on most days of the week. Exercise can help lower blood pressure and improve overall cardiovascular health.
  4. Limit alcohol consumption: Drinking too much alcohol can raise your blood pressure. It is recommended to limit alcohol intake to no more than one drink per day for women and two drinks per day for men.
  5. Don’t smoke: Smoking can damage your blood vessels and increase your risk of high blood pressure. Quitting smoking can help lower your blood pressure and improve your overall health.
  6. Reduce stress: Chronic stress can raise your blood pressure. Try to find ways to manage stress, such as through relaxation techniques, exercise, or talking to a therapist.
  7. Get enough sleep: Lack of sleep can raise your blood pressure. Aim for 7-9 hours of sleep per night.

It is also important to have your blood pressure checked regularly, as high blood pressure often has no symptoms. If you have high blood pressure, your healthcare provider may recommend additional lifestyle changes and/or medication to help lower it.

The link between weight and blood pressure

There is a strong link between weight and blood pressure. Being overweight or obese can increase your risk of developing high blood pressure (also known as hypertension). Losing excess weight can help lower blood pressure, especially if you carry most of your excess weight around your waist.

There are several ways in which excess weight can contribute to high blood pressure:

  1. Extra weight puts extra strain on the heart and blood vessels, which can cause blood pressure to rise.
  2. Fat cells, especially those around the waist, can produce hormones and other substances that can increase blood pressure.
  3. Being overweight or obese can increase the risk of other conditions that can raise blood pressure, such as type 2 diabetes and sleep apnea.

If you are concerned about your weight and blood pressure, it is important to speak with your healthcare provider. They can help you develop a plan to lose weight safely and effectively. Losing even a small amount of weight can have significant health benefits, including lower blood pressure.

High blood pressure in pregnancy

High blood pressure (also known as hypertension) during pregnancy can be a serious condition for both the mother and the baby. Pregnancy-induced hypertension (PIH) refers to the development of high blood pressure after the 20th week of pregnancy. It can occur in both first-time and subsequent pregnancies.

HBP Risk and complications during pregnancy

PIH can increase the risk of complications such as preterm labor, placental abruption, and fetal distress. It can also lead to a condition called preeclampsia, which can be life-threatening for both the mother and the baby if left untreated.

There are no specific causes of PIH, but certain factors can increase the risk, such as being older than 35, having a history of high blood pressure or preeclampsia, being overweight or obese, and having diabetes or kidney disease.

Recommendations for managing the condition during Pregnancy

If you have been diagnosed with PIH, it is important to follow your healthcare provider’s recommendations for managing the condition. This may include taking medication as prescribed, monitoring your blood pressure regularly, and getting regular prenatal care. It is also important to eat a healthy diet, get regular exercise (as approved by your healthcare provider), and manage stress to help manage blood pressure and reduce the risk of complications.

Low blood pressure concerns

Low blood pressure (also known as hypotension) is generally defined as a blood pressure reading of 90/60 mmHg or lower. In some cases, low blood pressure can be a sign of an underlying health condition, such as heart problems or dehydration. However, it is important to note that low blood pressure is not always a cause for concern and can sometimes be normal for a particular person.

If you have consistently low blood pressure readings and are experiencing symptoms such as dizziness, fainting, or fatigue, it is important to speak with your healthcare provider. They can help determine the cause of your low blood pressure and recommend any necessary treatment.

In some cases, low blood pressure can be treated by making lifestyle changes such as increasing your fluid and salt intake or wearing compression stockings to help improve circulation. In other cases, medication may be needed to help raise blood pressure to a healthy level.
