doppler effect represents a topic that has garnered significant attention and interest. Doppler ultrasound: What is it used for? Doppler ultrasound is a noninvasive test that can be used to measure the blood flow through your blood vessels. It works by bouncing high-frequency sound waves off red blood cells that are circulating in the bloodstream.
A regular ultrasound uses sound waves to produce images, but can't show blood ... Carotid ultrasound - Mayo Clinic. Carotid (kuh-ROT-id) ultrasound is a procedure that uses sound waves to look at blood flow through the carotid arteries. The carotid arteries are a pair of blood vessels on each side of the neck. They deliver blood from the heart to the brain.
Equally important, a carotid ultrasound also checks the thickness of the carotid artery wall and for blood clots. The dawn phenomenon: What can you do? The dawn phenomenon is an early-morning rise in blood sugar, also called blood glucose, in people with diabetes. The dawn phenomenon leads to high levels of blood sugar, a condition called hyperglycemia.
It usually happens between 4 a.m. The cause of the dawn phenomenon isn't clear. Tricuspid valve regurgitation - Symptoms and causes. The condition also may be called: Tricuspid regurgitation.
Tricuspid insufficiency. Some people are born with heart valve disease that leads to tricuspid regurgitation. This is called congenital heart valve disease. But tricuspid valve regurgitation also may occur later in life due to infections and other health conditions.
Mild tricuspid valve regurgitation may not cause symptoms or require ... Renal artery stenosis - Symptoms and causes - Mayo Clinic. Renal artery stenosis is when one or more arteries that carry blood to the kidneys narrow. These are called the renal arteries. Building on this, having narrowed renal arteries means the kidneys don't get enough oxygen-rich blood.
The kidneys need enough blood flow to help filter waste products and remove excess fluids. Less blood flow to the kidneys may injure kidney tissue and raise blood pressure throughout ... Peripheral artery disease (PAD) - Symptoms and causes. Furthermore, peripheral artery disease is usually a sign of a buildup of fatty deposits in the arteries, a condition called atherosclerosis.
Treatment for PAD includes exercising, eating healthy foods, and not smoking or using tobacco.
