When you first start taking Metformin, you will likely lose some weight as the medication can cause feelings of fullness and a loss of appetite. If you start taking the medication while following a strict diet and exercise plan, then you may see a significant reduction in weight. This is a more desirous side effect as it is strongly suggested that diabetics lose weight so that their bodies have better control of their glucose levels and an improved insulin resistance.


In the fight against hypertension, the best strategy is to recognize one’s individual risks-which might include genetic history, obesity or simple physical inactivity-and act accordingly. For the elderly, moderately high blood pressure might be less serious than it is in a middle-aged person. But even when blood pressure rises minimally past age 50, it’s still important to take the proper steps to ensure healthy senior years. A normal blood pressure is an important first step toward achieving long-term health. Hypertension might be a common problem-but fortunately it has plenty of solutions.
In addition to suppressing hepatic glucose production, metformin increases insulin sensitivity, enhances peripheral glucose uptake (by inducing the phosphorylation of GLUT4 enhancer factor), decreases insulin-induced suppression of fatty acid oxidation,[102] and decreases absorption of glucose from the gastrointestinal tract. Increased peripheral use of glucose may be due to improved insulin binding to insulin receptors.[103] The increase in insulin binding after metformin treatment has also been demonstrated in patients with NIDDM.[104]
The incidence of diabetes was 58% lower in the lifestyle group and 31% lower in individuals given metformin. Among younger people with a higher body mass index, lifestyle modification was no more effective than metformin, and for older individuals with a lower body mass index, metformin was no better than placebo in preventing diabetes.[35] After ten years, the incidence of diabetes was 34% lower in the group of participants given diet and exercise and 18% lower in those given metformin.[36] It is unclear whether metformin slowed down the progression of prediabetes to diabetes (true preventative effect), or the decrease of diabetes in the treated population was simply due to its glucose-lowering action (treatment effect).[37]

Sodium (salt) sensitivity: Some people have high sensitivity to sodium (salt), and their blood pressure increases if they use salt. Reducing sodium intake tends to lower their blood pressure. Americans consume 10-15 times more sodium than they need. Fast foods and processed foods contain particularly high amounts of sodium. Many over-the-counter medicines also contain large amounts of sodium. Read food labels and learn about salt content in foods and other products as a healthy first step to reducing salt intake. Fast food restaurants also make the salt and calorie content of their food available to consumers at their restaurants,


Rarely, too much metformin can build up in the body and cause a serious (sometimes fatal) condition called lactic acidosis. Lactic acidosis is more likely if you are an older adult, if you have kidney or liver disease, dehydration, heart failure, heavy alcohol use, if you have surgery, if you have X-ray or scanning procedures that use iodinated contrast, or if you are using certain drugs. For some conditions, your doctor may tell you to stop taking this medication for a short time. Ask your doctor or pharmacist for more details.
Metformin has been suggested as increasing production of lactate in the large intestine, which could potentially contribute to lactic acidosis in those with risk factors.[76] However, the clinical significance of this is unknown, and the risk of metformin-associated lactic acidosis is most commonly attributed to decreased hepatic uptake rather than increased intestinal production.[31][75][77]
Hypertensive Crisis This is an occurrence of high blood pressure that requires medical attention. If you have a blood pressure reading of 180/120 mm Hg, wait five minutes and test again. If it is consistently this high, contact your doctor immediately. If blood pressure is higher than 180/120 mm Hg and you are experiencing chest pain, shortness of breath, back pain, numbness and weakness, change in vision, and difficulty speaking, you may have organ damage and should call 911.

Although it's most common in older adults, hypertension can also affect children. The normal blood pressure for a child is dependent upon the child's age, gender, and height. Your doctor can tell if your child's blood pressure is abnormal. Children are at higher risk for hypertension if they are overweight, African-American, or if they have a family history of the condition. Children with high blood pressure may benefit from the DASH diet and taking medications. Children with high blood pressure should also maintain a healthy weight and avoid tobacco smoke.
Many expert groups recommend a slightly higher target of 150/90 mmHg for those over somewhere between 60 and 80 years of age.[99][100][101][105] The JNC-8 and American College of Physicians recommend the target of 150/90 mmHg for those over 60 years of age,[13][106] but some experts within these groups disagree with this recommendation.[107] Some expert groups have also recommended slightly lower targets in those with diabetes[99] or chronic kidney disease with protein loss in the urine,[108] but others recommend the same target as for the general population.[13][103] The issue of what is the best target and whether targets should differ for high risk individuals is unresolved,[109] although some experts propose more intensive blood pressure lowering than advocated in some guidelines.[110]
Metformin can cause weight loss over time when combined with diet and exercise. However, metformin should not be used just for weight loss. It has the risk of serious side effects as well as interactions with other medications. Also, metformin doesn’t provide long-term weight loss. After stopping taking metformin, people typically gain back any weight they’ve lost from the drug.

Resistant hypertension is defined as high blood pressure that remains above a target level, in spite of being prescribed three or more antihypertensive drugs simultaneously with different mechanisms of action.[131] Failing to take the prescribed drugs, is an important cause of resistant hypertension.[132] Resistant hypertension may also result from chronically high activity of the autonomic nervous system, an effect known as "neurogenic hypertension".[133] Electrical therapies that stimulate the baroreflex are being studied as an option for lowering blood pressure in people in this situation.[134]

The guidelines also redefined the various categories of hypertension. It eliminated the category of prehypertension, which had been defined as systolic blood pressure of 120 to 139 mm Hg or diastolic pressure (the lower number in a reading) of 80 to 89 mm Hg. Instead, people with those readings are now categorized as having either elevated pressure (120 to 129 systolic and less than 80 diastolic) or Stage 1 hypertension (130 to 139 systolic or 80 to 89 diastolic).

The findings mean that an additional 14 percent of U.S. adults, or about 30 million people, will now be diagnosed as having high blood pressure, compared with the number diagnosed before the new guidelines. This will bring the total percentage of U.S. adults with high blood pressure to 46 percent, up from 32 percent previously. [9 New Ways to Keep Your Heart Healthy]

Too often, doctors prescribe the regular version without any consideration of the extended-release (ER) version. By taking the ER version, each dose is being introduced over the course of hours and hours versus all at once, which significantly reduces the unwanted gastric side effects. While it does cost more, it could greatly metformin’s side-effects.
An elevated blood pressure reading means that your blood pressure falls just above the normal level, corresponding to a systolic pressure between 120 and 129 or a diastolic pressure of 80 or less. The new guidelines eliminate the previous category of prehypertension. About one-fourth of Americans have elevated levels and they have two times the risk of heart disease compared with those who have lower blood pressures. Lifestyle changes can help many people with prehypertension lower their blood pressure.
There is no treatment available for the causes of portal hypertension. However, treatment can prevent or manage the complications. Diet, medication (nonselective beta-blockers), endoscopic therapy, surgery, and radiology procedures can all help in treating or preventing symptoms of portal hypertension. If these treatments are unsuccessful in treating symptoms, transjugular intrahepatic portosystemic shunt (TIPS) or distal splenorenal shunt (DSRA) are two procedures that may reduce pressure in the portal veins. Maintaining a healthy lifestyle may help to prevent portal hypertension.
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.
Once you have high blood pressure, you are expected to monitor and treat it for the rest of your life. There is a chance the high blood pressure returns to normal with lifestyle changes, but it’s challenging. Both lifestyle changes and medicine are typically needed in order to maintain a goal blood pressure. Treatment will also greatly lower the chance of heart attack, stroke, and other heart disease-related complications.
Dr. Rachel Bond, associate director of the Women's Heart Health Program at Lenox Hill Hospital in New York City, who was not involved with the guidelines, said she agreed with the new updates. "I believe this will allow for earlier detection [of high blood pressure], and allow for more lifestyle modification to prevent the long-term detrimental effects of untreated high blood pressure," Bond said.
Medications used to lower blood pressure include diuretics (e.g., hydrochlorothiazide*), beta-blockers (e.g., atenolol, metoprolol), ACE inhibitors (e.g., ramipril, enalapril, lisinopril), calcium channel blockers (e.g., nifedipine, amlodipine), angiotensin II receptor blockers (e.g., losartan, valsartan), and direct renin inhibitors (e.g., aliskiren).
4. Find an exercise that works for you (and do it). Moving more can help reverse high blood pressure. One meta-analysis of 65 studies found regular exercise provides both an acute and longer-term reduction in blood pressure. Whether you’re an exercise novice or a conditioned athlete, these four strategies can help you create an effective workout plan to optimize health.
When starting metformin, around a third of people suffer some degree of stomach irritation, which usually resolves quickly. Only 3 percent to 10 percent of people in clinical trials experience symptoms severe enough that they stop taking the drug. Higher doses tend to cause more irritation, at least when comparing 500 milligrams (mg) to higher doses. Little difference is seen between doses of 1,000 mg and 2,500 mg.
Most of the metformin side effects are the result of metformin preventing nutrient absorption in the GI tract, which by itself can cause a whole host of symptoms. This is why it is very important to watch your general state on metformin, consult with your doctor if anything is off, and take supplements to support and maintain your overall body health. A lot of metformin side effects can be curbed with proper supplementation as well as good diet.
Dr. Shiel received a Bachelor of Science degree with honors from the University of Notre Dame. There he was involved in research in radiation biology and received the Huisking Scholarship. After graduating from St. Louis University School of Medicine, he completed his Internal Medicine residency and Rheumatology fellowship at the University of California, Irvine. He is board-certified in Internal Medicine and Rheumatology.
3. Fairly recently, the difference between Systolic and Diastolic pressure, named "Pulse Pressure", has been gaining interest in the research community. This Pulse Pressure has been found to correlate linearly with heart attack risk - the higher the number, the higher the risk. According to this theory, a BP of 140/ 90 (PP=50) is more desirable than a BP of 140/ 80 (PP=60).
