How to lower high blood pressure

Blood pressure refers to the force created by blood flowing through the arteries, impacting the artery walls. The narrower and stiffer the arteries are, the higher the blood pressure becomes. Normal blood pressure is always below 120/80. If the reading is higher, you have high blood pressure (hypertension). Once you understand blood pressure, you can follow these simple steps to adjust your lifestyle and lower it.

Learn the stages of hypertension. If your blood pressure is above 120/80, you have hypertension. The levels of hypertension vary depending on the intensity of the heart's pressure.

• Blood pressure between 120-139/80-89 is classified as prehypertension.
• Stage 1 hypertension ranges from 140-159/90-99.
• Stage 2 hypertension is 160 or higher/100 or higher.

Diagnosing high blood pressure. Blood pressure fluctuates throughout the day. It decreases when you are at rest and rises when you are excited, stressed, or physically active. This is why a diagnosis of high blood pressure is made only after seeing a doctor at least three times over several weeks or months. In some cases, the body may have two independent blood pressure readings: systolic and diastolic.

• The final diagnosis is based on the highest reading. For example, if your blood pressure is 162/79, you have Stage 2 hypertension.

Understanding primary hypertension. There are two types of high blood pressure: primary and secondary. Primary hypertension develops over many years and can have several contributing factors. It is typically associated with multiple independent risk factors. The main risk factor is age: the older you get, the more likely you are to develop hypertension due to arteries becoming stiff and narrow. Genetics also play a role, as individuals with parents who have high blood pressure are at a higher risk. Studies have shown that the genetic component of hypertension can account for up to 30%.

• If you are obese, have diabetes, or suffer from lipid metabolism disorders, you are also at risk for high blood pressure. Weight gain is a significant risk factor, as excess body mass increases the strain on the cardiovascular system. Over time, metabolic disturbances in fat and sugar metabolism contribute to hypertension. Diabetes and lipid metabolism disorders also affect fat and sugar metabolism.
• Those who experience chronic stress, anxiety, and depression are more likely to develop hypertension.
• Black individuals tend to be at higher risk for hypertension, and it is often more severe. This is believed to be the result of environmental, socioeconomic, and genetic factors.

Understanding secondary hypertension. This form of high blood pressure is caused by an underlying health condition. Conditions such as kidney disease, which regulates the balance of fluids in the blood and removes excess water, can cause both acute and chronic kidney dysfunction. This results in water retention, increased blood volume, and consequently, high blood pressure.

• You may develop secondary hypertension if you have an adrenal tumor that produces hormones affecting heart rate, blood vessel constriction, and kidney function, leading to high blood pressure.
• Other causes include thyroid disease, which alters thyroid hormone levels affecting heart rate and blood pressure. Sleep apnea can also place pressure on the respiratory and circulatory systems, potentially leading to hypertension.
• Certain medications, both prescription and over-the-counter, have been shown to increase blood pressure. These include oral contraceptives, NSAIDs, antidepressants, steroids, decongestants, and stimulants. Additionally, the use of illicit drugs such as cocaine and methamphetamine can lead to hypertension.
• A diet high in salt can also contribute to the development of high blood pressure.

Monitoring blood pressure. High blood pressure can persist for months or even years without showing any symptoms, but its effects can lead to serious health problems or even death. Typically, health issues caused by high blood pressure arise from two stages of health: first, the blood vessels narrow and harden, and second, this reduces blood flow to vital organs such as the heart, brain, kidneys, eyes, and nerves. This can cause severe complications and potentially be life-threatening if not detected early.

• You should check your blood pressure at a pharmacy or purchase a home blood pressure monitor to keep track of your levels. If you suspect your blood pressure is rising, consult a doctor for a thorough diagnosis.

Exercise regularly. You can incorporate various physical activities into your daily routine to help improve high blood pressure. Cardiovascular exercises such as walking, running, or swimming, along with strength training, are excellent options. The American Heart Association recommends adults to engage in at least 30 minutes of exercise five days a week, totaling 150 minutes for better heart health. Alternatively, you can aim for at least 25 minutes of vigorous-intensity aerobic exercise three times a week, totaling 75 minutes. Additionally, you should include moderate or heavy muscle-strengthening activities at least two days a week.

• If the recommended activity level seems overwhelming, adjust it according to your capabilities. It's better to move a little than to remain sedentary. Even short walks are more beneficial than lying on the couch.
• Physical activity also helps fight obesity. A combination of a healthy diet and exercise aids in weight loss and lowering blood pressure.

Avoid stress. Stress, anxiety, and depression can increase the risk of high blood pressure. It's important to learn how to manage and cope with stress to improve both your mental and physical health. Pursuing hobbies, practicing meditation, and engaging in yoga are effective ways to relax.

• If you are struggling with anxiety or depression, it is advisable to consult a doctor.

Limit alcohol consumption. Men should limit their alcohol intake to a maximum of 2 drinks per day, while women should have no more than 1 drink.

• If you're an alcoholic and wish to reduce your alcohol consumption, it is recommended to gradually cut down over a few weeks. Suddenly quitting alcohol can result in serious hypertension risks.

Quit smoking. Smoking is one of the leading causes of cardiovascular death. The chemicals in cigarettes increase heart rate and constrict blood vessels, raising blood pressure. More importantly, smoking leads to artery hardening over time, and this effect can persist for many years even after quitting.

Limit caffeine intake. Caffeine increases heart rate and blood pressure, especially in those who do not consume it regularly. At high doses, it can lead to arrhythmias. It is recommended not to exceed 400 mg of caffeine per day.

• To monitor your daily intake, be aware of the caffeine content in your beverages. A 240 ml cup of coffee contains 100-150 mg, 30 ml of espresso contains 30-90 mg, and 240 ml of caffeinated tea contains 40-120 mg.

Use herbal remedies. While not scientifically proven, certain herbs have been suggested to improve blood pressure. However, these should not replace scientifically researched medications. Instead, herbal remedies should only be included in your diet with approval from your doctor.

• One option is fly agaric leaf extract, commonly used in China as tea to boost blood circulation to the heart.
• You may try hawthorn berry extract, which is believed to enhance blood supply to the heart and aid in heart metabolism.
• Garlic extract is another option for preventing cardiovascular diseases. Garlic is known for its ability to control high blood pressure and cholesterol levels.
• Hibiscus flowers can be used as a supplement or brewed into tea, which has diuretic effects and can enhance the efficacy of medications such as ACE inhibitors and high blood pressure drugs. You can also drink ginger tea or cardamom tea, an Indian remedy with natural blood pressure-lowering properties.
• Drink coconut water. It is rich in potassium and magnesium, which help regulate muscle function.
• Taking fish oil, which contains omega-3 fatty acids, can help improve fat metabolism and reduce the risk of heart attacks and strokes.

Try the DASH diet (Dietary Approaches to Stop Hypertension). The DASH diet is widely accepted in the medical field as a starting point for treating high blood pressure. This eating plan emphasizes fruits, vegetables, low-fat dairy, whole grains, and lean proteins, while limiting salt, sugar, and fats.

• Most of the nutrition tips provided here are based on the DASH diet. To learn more about this plan and other dietary recommendations, you should consult your doctor.

Reduce salt intake. Sodium significantly impacts your body's blood pressure levels. Therefore, a primary goal of the DASH diet is to reduce the amount of salt you consume, both directly and through food.

• The recommended daily salt intake is 2,300 mg. If your doctor suggests a low-salt DASH diet, consider lowering your daily intake to 1,500 mg, which is less than one small teaspoon of salt.
• Most processed foods are extremely high in salt. Be cautious when consuming these foods while monitoring your salt intake. Even foods that don't taste salty can contain more salt than you might think. Always check product packaging for sodium content, listed in milligrams per serving on the nutritional label.
• Pay attention to portion sizes and track your daily salt consumption to keep it under 1,500 mg.

Add whole grains to your meals. The DASH diet recommends 6 to 8 servings of grains or whole grains each day. You should opt for whole grains instead of refined grains. Here are a few tips to help you avoid refined grains and choose healthier options.

• Examples of whole grains include quinoa, whole wheat, oats, rice, millet, and barley.
• Whenever possible, choose whole grain pasta instead of regular pasta, brown rice instead of white rice, and whole grain bread instead of white bread. Always check that the packaging states 100% whole grain.
• Choose foods with minimal processing. Packaged foods with more than three ingredients are often highly processed. Fresh produce, sold in its natural form, is typically healthier.

Consume more fruits and vegetables. Fruits and vegetables are fresh, flavorful, and incredibly beneficial for blood pressure and overall health. The DASH diet recommends eating 4 to 5 servings of fruits and vegetables each day. Varieties such as pumpkin, tomatoes, broccoli, spinach, artichokes, and carrots are rich in fiber, potassium, and magnesium.

• Your body needs these vitamins for normal function and to reduce high blood pressure.

Add more fruit to your diet. Fruits provide essential vitamins, minerals, and antioxidants that your body needs. They can be a great snack option and can replace refined sugars if desired. The DASH diet recommends consuming 4 to 5 servings of fruit each day.

• For more fiber, eat the skin of fruits like apples, kiwis, pears, and mangoes, which are safe to consume alongside the fruit’s flesh.

Eat lean protein. It is important to incorporate lean protein into your meals, but be mindful of the daily portion size. DASH advises limiting your intake to no more than 6 servings of lean protein per day, including chicken breast, soy products, or dairy.

• Before cooking lean meats, trim off excess fat or skin.
• Avoid frying meats. Instead, opt for grilling, boiling, or simmering as cooking methods.
• Eat more fresh fish (avoid frying). Fatty fish like salmon, rich in omega-3 fatty acids, are particularly beneficial for lowering high blood pressure.

Incorporate nuts, beans, and legumes into your meals. These foods are packed with omega-3 fatty acids, fiber, and phytonutrients. DASH recommends consuming 4 to 6 servings per week rather than daily.

• This limitation is due to the high caloric content of these foods, which should be consumed in moderation.
• Opt for healthy nuts like almonds, flaxseeds, walnuts, sunflower seeds, lentils, peas, and beans.

Limit your intake of sweets. If you are strictly following the DASH diet, you should only have 5 servings of sweet treats per week. For those with a sweet tooth, opt for lower-fat or fat-free options like fruit sorbet or crisp cookies.

Assess the need for medication. Often, lifestyle changes alone are not enough to bring blood pressure back to normal levels. In many cases, patients may need to seek assistance from medication. In such instances, the most effective treatment approach is to combine lifestyle changes with medication. Sometimes, multiple medications may be required at once. The initial treatment for high blood pressure often involves several different types of medications.

Consult with your doctor about thiazide diuretics. Medications such as chlorthalidone and hydrochlorothiazide are believed to reduce fluid volume in the body and relax blood vessels. You should take this medication once a day.

• Side effects of this medication include decreased potassium levels, which can cause muscle weakness and arrhythmias, as well as lowered sodium levels, which may lead to dizziness, vomiting, and fatigue.

Use calcium channel blockers. Medications like amlodipine, nicardipine, nifedipine, verapamil, or diltiazem work by relaxing blood vessel muscles. Generally, you should take these 1 to 3 times a day.

• Side effects may include swelling of the legs and a slower heart rate.

Take Angiotensin-converting enzyme (ACE) inhibitors. ACE inhibitors and Angiotensin II receptor blockers (ARBs) work by blocking a hormone called Angiotensin II, which normally narrows blood vessels. These medications also help the body retain water. You should take this medication 1 to 3 times daily.

• Common side effects include low blood pressure and slow heart rate, which can cause dizziness and fainting. Additionally, they may increase potassium levels, which can result in muscle weakness, arrhythmias, and coughing. Approximately 20% of patients on ACE inhibitors experience a dry cough within 1 to 2 weeks of starting the medication.
• ACE inhibitors and ARBs are particularly effective for patients aged 22-51.

Use antiarrhythmic and antihypertensive medications. These medications can be taken if you do not have adverse reactions to other drugs. They work by blocking signals from nerves and hormones in the body that cause blood vessels to narrow. You should take these medications 1 to 3 times a day.

• Side effects of antiarrhythmic drugs include coughing (especially for patients with asthma or allergies) and shortness of breath, low blood sugar, increased potassium levels, depression, fatigue, and sexual dysfunction.
• Side effects of antihypertensive medications include headaches, nausea, weakness, and weight gain.
• Antiarrhythmic medications are effective for patients aged 22 to 51.

• If you can maintain normal blood pressure for one to two years, your doctor may recommend reducing or completely stopping your medication. This is only possible if you continue to control these lifestyle changes. The main goal is to prevent high blood pressure, and with lifestyle modifications, weight loss, and reduced salt intake, you may be able to reduce or eliminate the need for medication altogether.
