1.Blood pressure systolic and what is systole in blood pressure?

Blood pressure is the force applied by spreading blood opposed to the walls of the blood vessels. It is consistent in millimeters of mercury (mmHg) and is defined by two numbers.

1. The systolic pressure 

2. The diastolic pressure.

The systolic pressure is the greater number and describe the pressure in the arteries when the heart beats, and pump blood out into the circulatory system. This is known as systole. During systole, the heart contracts or bond and the blood is pumped out of the heart and into the arteries. The force produced by the reduction of the heart matter the pressure in the arteries to proceed, relating in the systolic blood pressure reading.

A healthy systolic blood pressure is commonly near 120 mmHg, while high systolic blood pressure (hypertension) is near about 130 mmHg or higher. Low systolic blood pressure (hypotension) is less than 90 mmHg.

    2. When blood pressure is high symptoms and causes.

High blood pressure, also called hypertension, appear when the force of blood pushing opposed to the walls of blood vessels is frequently too high. Blood pressure is calculated using two numbers: 

1. Systolic pressure (the top number) 

2. Diastolic pressure (the bottom number). 

A reading of 130/80 mmHg or higher is advised as high blood pressure.

    High blood pressure symptoms:

Symptoms of high blood pressure can be extinct or negative, which is often called the "silent killer." Some people with high blood pressure may face headaches, reducing of breath, or nosebleeds, but these symptoms are not solid symbols and are not always present.

  High blood pressure causes:

Genetics: 

High blood pressure mostly run in families, and specific genetic causes increase your risk.

Age: 

As you get older, your chances of high blood pressure rises.

Lifestyle factors: 

An unhealthy or toxic diet, lack of exercise, smoking, and unwanted alcohol drinking can all devoted to high blood pressure.

Medical conditions: 

Medical conditions, like kidney disease, sleep interval, and thyroid problems, can rises your risk of high blood pressure.

Medications: 

Medications, like birth control pills and some without a prescription cold remedies, can raise blood pressure.

It's important to adviser your blood pressure regularly, particularly if you have risk for high blood pressure. If left untreated, high blood pressure can edge to serious health problems like heart disease, punch, and kidney failure. Treatment may involve changing in lifestyle, such as regular exercise, healthy diet, and medications prescribed by a healthcare provider.

    3. When blood pressure is low symptoms and causes.

Low blood pressure, also called hypotension, a condition when blood pressure in arteries is less than normal, resulting in deficient blood flow in your body. The normal blood pressure is typically around 120/80 mmHg. A blood pressure reading lower than 90/60 mmHg is considered hypotension.

       Low blood pressure symptoms:

Dizziness or weakness 

Fainting or loss of sensibility 

Fatigue or weakness

Dim vision

Nausea or vomiting

Rapid breathing

Cold, clammy, dull skin

Rapid, weak beating.

   Low blood pressure Causes:

Dehydration: 

When the body waste more fluid than it takes in, it can cause low blood pressure.

Blood loss:

Loss of blood due to injury, surgery or other medical situations can cause a low blood pressure.

Medications: 

Some medications like beta-blockers, and some types of antidepressive can cause low blood pressure.

Heart conditions: 

Bradycardia (a slow heart rate) and valve problems can cause low blood pressure.

Endocrine problems: 

Disorders of thyroid gland can cause low blood pressure.

Allergic reactions: 

Serious allergic reactions, can cause low blood pressure.

Infection: 

Infections like septicemia can cause low blood pressure.

If you are deal with symptoms of low blood pressure, it is important to follow medical attention, especially if you have symptoms then carry on or deteriorate.

   4. Blood pressure medication.

BP medications are used to treat hypertension, or high blood pressure. There are many levels of BP medications, each working in various ways to help lower blood pressure. Some common levels of blood pressure medications include:

Diuretics: 

These drugs help the kidneys to remove extra salt and water from the body, which can help lower blood volume and blood pressure. Examples: hydrochlorothiazide and furosemide.

ACE inhibitors: 

These drugs block the development of hormone called angiotensin II, which can cause blood vessels to narrow or thin and blood pressure to rise. 

Examples: lisinopril and enalapril.

Calcium channel blockers: 

These drugs block calcium from entering the muscle cells in the walls of blood vessels, which can help to relax the vessels and lower blood pressure. 

Examples: Amlodipine and verapamil.

Beta blockers: 

These drugs prevent the issues of adrenaline on the heart and blood vessels, which can reduce the heart rate and force of heart's shrinkage, best for lower blood pressure. Examples: Atenolol and metoprolol.

Angiotensin receptor blockers (ARBs): 

These drugs prevent the issues of angiotensin II on blood vessels, which can help soften the vessels and lower blood pressure. Examples: losartan and valsartan.

It's important to know that blood pressure medications should be prescribed by a healthcare provider, as they can have hidden side effects and reactions with other medications. Further more, lifestyle changes such as managing a healthy weight, exercise regularly, and eating a balanced diet can also help lower blood pressure.
