Cirrhosis of the liver is the most common cause of portal hypertension. In cirrhosis, the scar tissue (from the healing of liver injury caused by hepatitis, alcohol, or other liver damage) blocks the flow of blood through the liver. Blood clots in the portal vein, blockages of the veins that carry blood from the liver to the heart, parasitic infection (schistosomiasis), and focal nodular hyperplasia are also causes of portal hypertension.
Metformin helps by reducing the amount of sugar, or glucose that is produced by the liver and also helps release the glucose from the liver into the body. The drug also helps to increase sensitivity to insulin by decreasing blood sugar production, reducing hyperglycemia, reducing triglycerides, improving transport of insulin and helping in weight management. In combination, all those factors lead to much-improved insulin sensitivity, which is especially helpful in cases of insulin resistance.
It’s no different for those reaching their senior years. While nearly one in three Americans suffers from hypertension, as high blood pressure is often called, blood pressure typically increases with age, especially once one has passed middle age. According to the National Heart, Lung,and Blood Institute, someone with healthy blood pressure at age 50 has a 90% chance of developing hypertension later in life.
Over time, high blood pressure, also known as hypertension, can damage your blood vessels, allowing cholesterol and other substances to build up. High blood pressure also increases your heart’s workload, which can affect its ability to pump blood and could lead to a heart attack. If left untreated, high blood pressure increases your risk of coronary artery disease and other heart problems. It is the most serious risk factor for stroke.

In those with polycystic ovarian syndrome there is tentative evidence that metformin use increases the rate of live births.[38] This includes in those who have not been able to get pregnant with clomiphene.[39] Metformin does not appear to change the risk of miscarriage.[38] A number of other benefits have also been found both during pregnancy and in non pregnant people with PCOS.[40][41] In women with PCOS undergoing in vitro fertilization evidence does not support a benefit with respect to live births.[42] The evidence does not support general use during pregnancy for improving maternal and infant outcomes in obese women.[43]
Blood pressure (BP) is the pressure of circulating blood on the walls of blood vessels. Most of this pressure is due to the work done by the heart in pumping blood round the circulation. Used without further specification, "blood pressure" usually refers to the pressure in large arteries of the systemic circulation. Blood pressure is usually expressed in terms of the systolic pressure (maximum during one heartbeat) over diastolic pressure (minimum in between two heartbeats) and is measured in millimeters of mercury (mmHg), above the surrounding atmospheric pressure.
The relationship between metformin and weight is unclear, but several theories provide a plausible explanation for weight fluctuations. Reduced hunger is one proven side effect of metformin, according to the Mayo Clinic. It might not appear as if you’re eating less with this drug, but the number of calories you’re currently consuming for breakfast, lunch, and dinner might be lower than your normal food intake. This subtle change in appetite could be responsible for a gradual decline in weight.

To make an official diagnosis of high blood pressure you will need to see your doctor. Often your blood pressure will be checked on at least two different visits, at different times of the day. Your doctor may ask you to keep a blood pressure log for a short time in order to see your overall blood pressure trends. If your blood pressure is consistently over 134/80, your doctor will work with you to determine the best regimen for treating your high blood pressure.

She'll inflate the cuff to a pressure higher than your systolic blood pressure, and it will tighten around your arm. Then she'll release it. As the cuff deflates, the first sound she hears through the stethoscope is the systolic blood pressure. It sounds like a whooshing noise. The point where this noise goes away marks the diastolic blood pressure.
The sympathetic nervous system is stimulated by exercise, stress, anxiety, pain, anger, and fear, which increases blood pressure. Blood pressure returns to baseline within five minutes of rest following activity. Try it out. Have a peer take your blood pressure. Then, run on the spot or do some other cardiac activity for five minutes. Have the peer take your blood pressure again, and then lie down and rest for five minutes. Take the blood pressure again. Note the changes.
Metformin treatment of people at a prediabetes stage of risk for type 2 diabetes may decrease their chances of developing the disease, although intensive physical exercise and dieting work significantly better for this purpose. In a large U.S. study known as the Diabetes Prevention Program, participants were divided into groups and given either placebo, metformin, or lifestyle intervention and followed for an average of three years.

During each heartbeat, blood pressure varies between a maximum (systolic) and a minimum (diastolic) pressure.[50] The blood pressure in the circulation is principally due to the pumping action of the heart.[51] Differences in mean blood pressure drive the flow of blood around the circulation. The rate of mean blood flow depends on both blood pressure and the resistance to flow presented by the blood vessels. In the absence of hydrostatic effects (e.g. standing), mean blood pressure decreases as the circulating blood moves away from the heart through arteries and capillaries due to viscous losses of energy. Mean blood pressure drops over the whole circulation, although most of the fall occurs along the small arteries and arterioles.[52] Pulsatility also diminishes in the smaller elements of the arterial circulation, although some transmitted pulsatility is observed in capillaries.[53]

Broad interest in metformin was not rekindled until the withdrawal of the other biguanides in the 1970s. Metformin was approved in Canada in 1972,[128] but did not receive approval by the U.S. Food and Drug Administration (FDA) for type 2 diabetes until 1994.[129] Produced under license by Bristol-Myers Squibb, Glucophage was the first branded formulation of metformin to be marketed in the U.S., beginning on March 3, 1995.[130] Generic formulations are now available in several countries, and metformin is believed to have become the world's most widely prescribed antidiabetic medication.[126]

Dietary changes can help control blood pressure. One diet designed to promote lower blood pressure is known as the DASH diet. This stands for Dietary Approaches to Stop Hypertension. The DASH diet recommends eating more vegetables, fruits, whole grains, low-fat dairy products, poultry, nuts, and fish. Red meat, saturated fats, and sweets should be avoided. The DASH diet can lower blood pressure within 2 weeks. It can also help to reduce your intake of sodium. The following is the DASH diet suggested daily intake:
Fortunately, the senior years are not too late to take an active role in lowering blood pressure. Managing blood pressure can be as simple as increasing physical activity and regulating one’s diet. In those cases when a change in lifestyle doesn’t significantly impact hypertension, prescription drugs have proven very effective in regulating blood pressure.
Hypertension defined as elevated blood pressure over several visits affects 1% to 5% of children and adolescents and is associated with long term risks of ill-health.[89] Blood pressure rises with age in childhood and, in children, hypertension is defined as an average systolic or diastolic blood pressure on three or more occasions equal or higher than the 95th percentile appropriate for the sex, age and height of the child. High blood pressure must be confirmed on repeated visits however before characterizing a child as having hypertension.[89] Prehypertension in children has been defined as average systolic or diastolic blood pressure that is greater than or equal to the 90th percentile, but less than the 95th percentile.[89] In adolescents, it has been proposed that hypertension and pre-hypertension are diagnosed and classified using the same criteria as in adults.[89]
Seven herbs and supplements for type 2 diabetes The uncontrolled blood sugar levels in diabetes have the potential for a herbal helping hand.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
It is usually only when a person is in the midst of what is known as a hypertensive crisis — a period of extremely high blood pressure with a reading of 180/120 millimeters of mercury (mm Hg) or higher — that she or he will experience symptoms, such as a headache. This is considered a medical crisis, and if it occurs, you should call 911 and get emergency help.
Start low and go slow. When starting metformin, most people do well with starting with 500 mg at night or with dinner, and staying at this dose for a full week. At that point, a second 500-mg pill can be added in the morning. After another week, a third pill can be added to the evening dose. After one more week, a fourth pill can be added to the morning dose, so that by the end of the month, the full daily dose of 2,000 mg is being taken.
Diabetics often complain of unexplained pain in the legs, especially calf muscles. The heart is the most important muscle in the human body and loss of CoQ10 causes a feeling of ‘heaviness’ in the heart.  Metformin causes depletion of CoQ10, which is critical for muscle energy. One of the key vitamin-like compounds that is depleted by Metformin (Biguanides) is called Coenzyme Q10 or CoQ10. It is also called ubiquinone, from the word ubiquitous, meaning everywhere. It is needed for energy production in, literally, every muscle of the human body. Depletion of this vital compound leads to lack of energy and muscle pains. Another impact of the loss of CoQ10 on cardiac health shows itself in stubborn swelling in the legs and feet.

When discussing blood pressure issues, the healthcare professional may ask questions about past medical history, family history, and medication use, including prescriptions, over-the-counter medications, herbal remedies, and food additives. Other questions may include lifestyle habits, including activity levels, smoking, alcohol consumption, and illegal drug use.

Hypertension may not produce any symptoms, even if you have had it for years. That's why it is sometimes referred to as a "silent killer." It's estimated that 1 out of every 5 people with high blood pressure aren't aware that they have this major risk factor for strokes and heart attacks. If not properly treated, high blood pressure can damage the heart and circulation, lungs, brain, and kidneys without causing noticeable symptoms. Symptoms of high blood pressure may be present in those who have an extremely high blood pressure. Symptoms of extremely high blood pressure include the following:
Creatinine is a chemical waste molecule that is generated from muscle metabolism. Creatinine is produced from creatine, a molecule of major importance for energy production in muscles. Creatinine has been found to be a fairly reliable indicator of kidney function. As the kidneys become impaired the creatinine level in the blood will rise. Normal levels of creatinine in the blood vary from gender and age of the individual.
It is a liquid formulation containing metformin hydrochloride as the active compound. It is available in two flavored formulations — cherry and strawberry — and delivers 500 mg of metformin in 5 ml of the solution. The formulation contains artificial sweeteners like saccharin, sucralose, and xylitol. To meet the daily metformin dosages, patients need to take as much as 25 ml of the syrup. Thus they should practice caution against consuming large amounts of artificial sweeteners.
A simple view of the hemodynamics of systemic arterial pressure is based around mean arterial pressure (MAP) and pulse pressure. Most influences on blood pressure can be understood in terms of their effect on cardiac output[54] and systemic vascular resistance. Cardiac output is the product of stroke volume and heart rate, and stroke volume is influenced by blood volume. In the short-term, the greater the blood volume, the higher the cardiac output. This may explain in part the relationship between dietary salt intake and increased blood pressure, where increased salt intake may increase blood volume potentially resulting in higher arterial pressure. However, this varies with the individual and is highly dependent on autonomic nervous system response and the renin–angiotensin system.[55][56][57] In the longer-term the relationship between volume and blood pressure is more complex.[58] In simple terms systemic vascular resistance is mainly determined by the caliber of small arteries and arterioles. The resistance attributable to a blood vessel depends on its radius as described by the Hagen-Poiseuille's equation (resistance∝1/radius4). Hence, the smaller the radius, the very much higher the resistance. Other physical factors that affect resistance include: vessel length (the longer the vessel, the higher the resistance), blood viscosity (the higher the viscosity, the higher the resistance)[59] and the number of vessels, particularly the smaller numerous, arterioles and capillaries. The presence of an arterial stenosis increases resistance to flow, however this increase in resistance rarely increases systemic blood pressure because its contribution to total systemic resistance is small, although it may profoundly decrease downstream flow.[60] Substances called vasoconstrictors reduce the caliber of blood vessels, thereby increasing blood pressure. Vasodilators (such as nitroglycerin) increase the caliber of blood vessels, thereby decreasing arterial pressure. In the longer term a process termed remodeling also contributes to changing the caliber of small blood vessels and influencing resistance and reactivity to vasoactive agents.[61][62] Reductions in capillary density, termed capillary rarefaction, may also contribute to increased resistance in some circumstances.[63]
A blood pressure reading contains two numbers: systolic pressure and diastolic pressure. Systolic pressure is the top or first number in your blood pressure reading; it indicates the pressure within your arteries when your heart pumps out blood. Diastolic pressure is the bottom number, and shows the pressure in your arteries while your heart is filling with blood.

AMPK probably also plays a role in increased peripheral insulin sensitivity, as metformin administration increases AMPK activity in skeletal muscle.[105] AMPK is known to cause GLUT4 deployment to the plasma membrane, resulting in insulin-independent glucose uptake. Some metabolic actions of metformin do appear to occur by AMPK-independent mechanisms; the metabolic actions of metformin in the heart muscle can occur independent of changes in AMPK activity and may be mediated by p38 MAPK- and PKC-dependent mechanisms.[106]

If you experience any of the following symptoms, stop taking metformin and call your doctor immediately: extreme tiredness, weakness, or discomfort; nausea; vomiting; stomach pain; decreased appetite; deep and rapid breathing or shortness of breath; dizziness; lightheadedness; fast or slow heartbeat; flushing of the skin; muscle pain; or feeling cold, especially in your hands or feet.

Before having surgery or any X-ray/scanning procedure using iodinated contrast, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). You may need to stop this medication for a short time for the surgery/procedure. Ask your doctor or dentist for instructions before your surgery/procedure.

Blood pressure is given as a reading of two numbers, such as 110/70. The higher number (systolic) is the pressure when the heart beats. The diastolic, or lower number shows the pressure between the heartbeats, while the relaxed heart is refilling with blood. Normal blood pressure readings are lower than 120/80. The cause of most hypertension is unknown. Occasionally, conditions of the kidney or adrenal gland are the cause of high blood pressure.

The United States Preventive Services Task Force recommends ambulatory blood pressure measurement for accurate diagnosis of hypertension. Although you may have elevated blood pressure when measured in your doctor's office, this can be the result of "white coat hypertension." Screening by your healthcare provider may also miss "masked hypertension." 12- and 24-hour average blood pressures using ambulatory blood pressure monitoring are often significantly different from readings taken in a clinic or hospital setting, and result in fewer patients requiring treatment, with significantly fewer patients requiring treatment as a result. Other patients may have elevated blood pressure averages discovered with ambulatory monitoring that place them at risk for stroke and cardiovascular disease even when the readings obtained in a healthcare setting are normal.

The brain requires unobstructed blood flow to nourish its many functions. Very high, sustained blood pressure will eventually cause blood vessels to weaken. Over time these weaken vessels can break, and blood will leak into the brain. The area of the brain that is being fed by these broken vessels start to die, and this will cause a stroke. Additionally, if a blot clot blocks a narrowed artery, blood ceases to flow and a stroke will occur.
Drinking too much alcohol is a risk factor for high blood pressure. The American Heart Association guidelines recommend the consumption of no more than two alcoholic drinks per day for men and no more than one drink a day for women. One drink is defined as one 12-ounce beer, 4 ounces of wine, 1.5 ounces of 80-proof spirits, or 1 ounce of 100-proof spirits. Adults who consume more than three drinks in one sitting temporarily increase their blood pressure. However, binge drinking can lead to long-term increased blood pressure.

In addition to an electrocardiogram (ECG) to evaluate possible heart damage, an echocardiogram may be used to see if your heart has become enlarged or if you have other cardiac problems related to hypertension, like blood clots or heart valve damage. Doppler ultrasound examination can be used to check the blood flow through the arteries to determine if they have narrowed, thus contributing to high blood pressure.
In the 19th and 20th centuries, before effective pharmacological treatment for hypertension became possible, three treatment modalities were used, all with numerous side-effects: strict sodium restriction (for example the rice diet[152]), sympathectomy (surgical ablation of parts of the sympathetic nervous system), and pyrogen therapy (injection of substances that caused a fever, indirectly reducing blood pressure).[152][158]

Lifelong control of hypertension will minimize the risk of developing heart attack, stroke, kidney failure, blindness, and a variety of other illnesses. Unlike other illnesses in which medications are taken for only a short period of time, high blood pressure medication is usually expected to be taken for the rest of the individual's life. It is uncommon, but not rare, that significant lifestyle changes can lower blood pressure readings to normal.
In Europe hypertension occurs in about 30-45% of people as of 2013.[12] In 1995 it was estimated that 43 million people (24% of the population) in the United States had hypertension or were taking antihypertensive medication.[141] By 2004 this had increased to 29%[142][143] and further to 32% (76 million US adults) by 2017.[7] In 2017, with the change in definitions for hypertension, 46% of people in the United States are affected.[7] African-American adults in the United States have among the highest rates of hypertension in the world at 44%.[144] It is also more common in Filipino Americans and less common in US whites and Mexican Americans.[6][145] Differences in hypertension rates are multifactorial and under study.[146]

2. How did I get the numbers? I started with the commonly seen "Systolic/ Diastolic pairs" seen in the literature - 200/120, 160/100, 140/90, 120/80 and 90/60. From there, I interpolated and extrapolated all the other numbers. Note that these are AVERAGE relationships. For instance, instead of 140/90, your BP may be 140/100, or 140/80. Each individual will have a unique systolic-diastolic relationship. If your S/D difference varies significantly from the averages shown above, this can be helpful in assessing your particular cardiovascular condition.
What is a normal blood pressure? Blood pressure is essential to life because it forces the blood around the body, delivering all the nutrients it needs.
