Coughing is an important way to keep your throat and airways clear. However, excessive coughing may mean you have an underlying disease or disorder. Some coughs are dry, while others are considered productive. A productive cough is one that brings up mucus. Mucus is also called phlegm or sputum. Coughs can be either acute or chronic: Acute coughs usually begin suddenly. They are often due to a cold, flu, or sinus infection. They usually go away after 2 to 3 weeks; Chronic coughs last longer than 2 to 3 weeks.
|
|
Coughs, those mini-explosions in your throat, are valuable weapons in your body's self-defense arsenal. Their assignment: keep airways clear by quickly expelling intruders from the lower respiratory system -- principally your throat and upper lungs. If dust, fluid, viruses, bacteria or even tumors block any part of this region, your cough reflex takes explosive action.
|
|
Your doctor should evaluate you if you are having symptoms that suggest a more serious cause, such as a bacterial infection, or if your symptoms aren't manageable with over-the-counter remedies or the passing of time.
|
|
A cough is a forceful release of air from the lungs that can be heard. Coughing protects the respiratory system by clearing it of irritants and secretions.

Hypertension is the term doctors use for high blood pressure. Blood pressure readings are measured in millimeters of mercury (mmHg) and usually given as 2 numbers. For example, 140 over 90 (written as 140/90. The top number is your systolic pressure, the pressure created when your heart beats. It is considered high if it is consistently over 140; The bottom number is your diastolic pressure, the pressure inside blood vessels when the heart is at rest. It is considered high if it is consistently over 90. Either or both of these numbers may be too high. Pre-hypertension is when your systolic blood pressure is between 120 and 139 or your diastolic blood pressure is between 80 and 89 on multiple readings. If you have pre-hypertension, you are more likely to develop high blood pressure at some point. See also: Blood pressure

Blood pressure is the force with which blood pushes against the artery walls as it travels through the body. Like air in a balloon, blood fills arteries to a certain capacity- and just as too much air pressure can cause damage to a balloon, too much blood pressure can harm healthy arteries.
