Your blood pressure is the force of blood pushing against your blood vessel walls. When you have high blood pressure, the pressure in your arteries is elevated. One in four adults, about 50 million Americans, have high blood pressure. When untreated, it can increase the risk of heart attack and stroke.

High blood pressure usually has no symptoms, so it is often called the "silent killer." The only way to tell if you have high blood pressure is to get it checked regularly. The Red Cross checks your blood pressure before every donation!

Body mass index (BMI) is a tool that is used to gauge total body fat based on a person’s weight and height. It is one of the most accurate ways to determine when extra pounds result in a health risk. For adults over 20 years old, BMI falls into one of these categories:

• BMI Below 18.5 – Underweight
• BMI 18.5-24.9 – Normal
• BMI 25.0-29.9 – Overweight
• BMI 30.0 and Above  – Obese

The relationship between fatness and BMI differs with age, gender and fitness. Two people can have the same BMI and yet have a different percentage of body fat, so BMI is only one piece of a person's health profile.

If you are a platelet donor, you may be told to increase your calcium intake a day or two prior to your donation. The anticoagulant that is used during a platelet donation temporarily binds with the calcium in your blood to be removed from your body. Making sure you have plenty of calcium in your system will help you feel comfortable during your donation.

Your body needs calcium to perform many regular functions. Calcium is the foundation for strong, healthy bones, muscles and teeth. Blood coagulation, transmission of nerve impulses, muscle contraction and relaxation, normal heartbeat and other functions also require small amounts of calcium.

Cholesterol is a soft, fat-like waxy substance found in the bloodstream and in all your body’s cells. Everyone has cholesterol in their body. It is important for the production of cells and some hormones and helps with other bodily functions.

Your body makes all of the cholesterol it needs, but it also gets cholesterol from foods. If you have too much cholesterol in your blood, your body can’t get rid of it and it can build up in your arteries. Then, you could be at risk for heart disease or stroke.

There are two types of cholesterol LDL or “bad” cholesterol and HDL or “good” cholesterol. LDL can join with fats and other substances to build up in the inner walls of your arteries. HDL helps carry the harmful cholesterol away from the arteries and helps protect you from heart attack and stroke.

• Cut down on foods which are high in saturated fat and cholesterol
• Enjoy at least 30 minutes of physical activity on most or all days of the week
• Eat more foods low in saturated fat and cholesterol and high in fiber
