Vascular Ultrasound

Vascular ultrasound uses sound waves to evaluate the body's circulatory system and help identify blockages in the arteries and veins and detect blood clots. A Doppler ultrasound study – a technique that evaluates blood flow through a blood vessel – is usually part of this exam. Ultrasound does not use ionizing radiation, has no known harmful effects, and provides images of soft tissues that don't show up on x-ray images.
Little or no special preparation is required for this procedure. However, you may occasionally be asked to fast beforehand. Leave jewelry at home and wear loose, comfortable clothing. You may be asked to wear a gown.

Constipation, which is a functional problem, makes it hard for you to have a bowel movement (or pass stools), the stools are infrequent (less than three times a week), or incomplete. Constipation is usually caused by inadequate "roughage" or fiber in your diet, or a disruption of your regular routine or diet.

Constipation causes you to strain during a bowel movement. It may cause small, hard stools and sometimes anal problems such as fissures and hemorrhoids. Constipation is rarely the sign that you have a more serious medical condition.
