In the latter case, the variables appearing in the coefficients are often called parameters, and must be clearly distinguished from the other variables. For example, in.
Many different conditions can cause fainting. These include heart problems such as irregular heart beats, seizures, low blood sugar (hypoglycemia), anemia (a deficiency in healthy oxygen carrying cells), and problems with how the nervous system (the body's system of nerves) regulates blood pressure.
Fainting, which is also called syncope, can be caused by many different things. Sometimes a specific cause for fainting cannot be found. A sudden drop in your blood pressure can cause you to faint. Sometimes your heart rate and blood vessels canât react fast enough when your bodyâs need for oxygen changes. This is very common among older people and in people who have certain health conditions, such as diabetes. Fainting can happen when: 1  You stand up too fast. 2  You work or play hard, especially if itâs very hot. 3  You begin to breathe too fast (called hyperventilating). 4  You get very upset. Being upset can affect the nerves that control your blood pressure. 5  Youâre taking medicine for high blood pressure.
