Sleep plays a vital role in good health and well-being throughout your life. The way you feel while you are awake depends in part on what happens while you are sleeping. During sleep, your body is working to support healthy brain function and maintain your physical health. In children and teens, sleep also helps support growth and development. Getting inadequate sleep over time can raise your risk for chronic health problems. It can also affect how well you think, react, work, learn, and get along with others. Learn how sleep affects your heart and circulatory system, metabolism, respiratory system, and immune system and how much sleep is enough.

Many factors play a role in preparing your body to fall asleep and wake up. Your body has several internal clocks, called circadian clocks. These typically follow a 24-hour repeating rhythm, called the circadian rhythm. This rhythm affects every cell, tissue, and organ in your body and how they work.

Your doctor may diagnose angina based on your medical history, a physical exam, and diagnostic tests and procedures. These tests can help assess whether you need immediate treatment for a heart attack. Some of these tests may help rule out other conditions.

Signs and symptoms vary based on the type of angina you have and on whether you are a man or a woman. Angina symptoms can differ in severity, location in the body, timing, and how much relief you may feel with rest or medicines. Since symptoms of angina and of heart attack can be the same, call 9-1-1 if you feel chest discomfort that does not go away with rest or medicine. Angina can also lead to a heart attack and other complications that can be life-threatening.

You may have an increased risk for angina because of your age, environment or occupation, family history and genetics, lifestyle, other medical conditions, race, or sex.

Angina happens when your heart muscle does not get enough oxygen-rich blood. Medical conditions, particularly ischemic heart disease, or lifestyle habits can cause angina. To understand the causes of angina, it helps to understand how the heart works.

The types of angina are stable, unstable, microvascular, and variant. The types vary based on their severity or cause.

Your doctor may diagnose cystic fibrosis based on your signs and symptoms and results from certain tests, such as genetic and sweat tests that are done to confirm screening tests.

Genetic testing may be performed to look for carriers, as well as to screen relatives of people who have cystic fibrosis.

Cystic fibrosis is an inherited disease caused by mutations in a gene called the cystic fibrosis transmembrane conductance regulator (CFTR) gene.

What to Expect If your doctor recommends pulmonary rehabilitation, you will receive care from a team of healthcare providers, who will design a plan that fits your needs based on the health of your lungs, your age, and other health factors. After your program ends, your team will assess your lung function again to see if your breathing has improved. Yes

Treatment for your aortic aneurysm will depend on its cause, its size and location, and the factors that put you at risk. Small aortic aneurysms may be managed with healthy lifestyle changes or medicine. The goal is to slow the growth of the aneurysm and lower the chance of rupture or dissection.

An aortic aneurysm may not cause any signs or symptoms until the aneurysm ruptures or dissects. The types of symptoms that occur before a rupture will depend on the location of the aneurysm and whether it has become large enough to affect other parts of your body. An aneurysm that ruptures or dissects is life-threatening.

If you have known risk factors for developing an aortic aneurysm, your doctor may recommend screening. To screen for an aortic aneurysm, your doctor may recommend an imaging study to look at and measure the aorta. An aneurysm can develop and grow without any symptoms until it ruptures or dissects—events that are both life-threatening. If the aneurysm is found early, treatment or surgery may slow its growth and prevent rupture or dissection.

You may have an increased risk of developing an aortic aneurysm because of your age, family history, genes, lifestyle habits, medical conditions, or sex.
