Diabetes can upset the balance between HDL and LDL cholesterol levels. People with diabetes tend to have LDL particles that stick to arteries and damage blood vessel walls more easily. Glucose (a type of sugar) attaches to lipoproteins (a cholesterol-protein package that enables cholesterol to travel through blood). Sugarcoated LDL remains in the bloodstream longer and may lead to the formation of plaque. People with diabetes tend to have low HDL and high triglyceride (another kind of blood fat) levels. Both of these boost the risk of heart and artery disease.
Low- and no-fat dairy foods are good sources of calcium and protein, which can help maintain a healthy blood pressure. Try to get three servings of dairy every day. Choose skim or 1% milk and low- or no-fat cheeses and yogurt. Frozen low-fat yogurt is OK, too. One serving equals 1 cup of yogurt or milk, or 1 1/2 ounces of cheese -- about the size of three dice.
A meta-analysis of individual patient data from randomized controlled trials found the lowest diastolic blood pressure for which cardiovascular outcomes improve is 85 mm Hg for untreated hypertensives and 80 mm Hg for treated hypertensives. The authors concluded "poor health conditions leading to low blood pressure and an increased risk for death probably explain the J-shaped curve". Interpreting the meta-analysis is difficult, but avoiding a diastolic blood pressure below 68–70 mm Hg seems reasonable because:
Fruits offer lots of fiber and vitamins that are good for your heart. Many also have potassium and magnesium, which lower blood pressure. Have four to five servings of fruit every day. One serving is a medium apple or orange, or 1/2 cup of frozen, fresh, or canned fruit. One-half cup of fruit juice or 1/4 cup of dried fruit also counts as a serving. Try adding bananas or berries to your breakfast cereal or have fruit for dessert.
Isolated systolic hypertension can be caused by underlying conditions such as artery stiffness, an overactive thyroid (hyperthyroidism) or diabetes. Occasionally, it can be caused by heart valve problems. It is the most common form of high blood pressure in people older than age 65, but it is possible for younger people to be affected by this type of high blood pressure as well.
Doctors typically use an inflatable arm cuff to measure blood pressure, which is recorded in millimeters of mercury (abbreviated as “mmHg”) and has two numbers. The top number, called systolic blood pressure, measures pressure in the arteries when the heart beats. The bottom number, called diastolic blood pressure, refers to blood pressure when the heart is at rest. When patients have a blood pressure above normal (120/80 mmHg), they are considered to have prehypertension or hypertension.
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. Here, we explain how to take your blood pressure, what the readings mean, and what counts as low, high, and normal. The article also offers some tips on how to maintain healthy blood pressure.
