Motion Sickness
Motion sickness is nausea, vomiting, and related symptoms caused by repetitive angular and linear acceleration and deceleration.
What are the symptoms of motion sickness?
Motion sickness is characterized by cycles of nausea and vomiting. These episodes may be preceded by yawning, salivation, pallor, cold sweat, and sleepiness. Dizziness, headache, fatigue, and general discomfort are also common. Once nausea and vomiting develop, a person with motion sickness is typically weak and unable to concentrate.

Cardiac Arrhythmia
Cardiac arrhythmia is a term that denotes a disturbance of the heart rhythm. Cardiac arrhythmias can range in severity from entirely benign to immediately life-threatening. If arrhythmia is suspected, a cardiologist should be consulted for confirmation. In addition, the use of natural substances for arrhythmia should always be supervised by a doctor.
What are the symptoms of cardiac arrhythmia?
Most arrhythmia does not result in symptoms, but people may experience anxiety, lightheadedness, dizziness, fainting, unusual awareness of the heartbeat, and sensations of fluttering or pounding in the chest.

Cardiomyopathy
Cardiomyopathy refers to abnormalities in the structure or function of the heart muscle. There are three major types of cardiomyopathy: dilated congestive, hypertrophic, and restrictive. The most prevalent form is dilated congestive cardiomyopathy (DCM). In people with DCM, the heart muscle is damaged, most commonly by coronary artery disease ( atherosclerosis). People with diabetes have been reported to be at increased risk of DCM. DCM can also be triggered by alcohol abuse, infections, exposure to certain drugs and toxins, nutritional deficiencies, connective tissue diseases, hereditary disorders, and pregnancy.
In DCM, the heart gradually loses its efficiency as a pump. Cardiomyopathy is a serious health condition and requires expert medical care rather than self-treatment. However, because of the associations between cardiomyopathy and diseases such as atherosclerosis, diabetes, hypertension, and congestive heart failure, lifestyle recommendations for the prevention of these conditions may also help prevent DCM.

Angina
Chest pain due to reduced blood flow to the heart is known as angina or angina pectoris. Hardening of the coronary arteries (atherosclerosis) that feed the heart is usually the underlying problem. It is important for treatment and prevention of angina (and for overall health) to learn more about atherosclerosis. Coronary artery spasms may also cause angina.
There are three main types of angina. The first is called stable angina. This type of chest pain comes on during exercise and is both common and predictable. Stable angina is most often associated with atherosclerosis. A second type, called variant angina, can occur at rest or during exercise. This type is primarily due to sudden coronary artery spasm, though atherosclerosis may also be a component. The third, most severe type is called unstable angina. This angina occurs with no predictability and can quickly lead to a heart attack. Anyone with significant, new chest pain or a worsening of previously mild angina must seek medical care immediately.
What are the symptoms of angina?
Common symptoms of angina include a squeezing pressure, heaviness, ache, or burning pain (like indigestion) in the chest that occur for 5 to 30 minutes at a time. These sensations are usually felt behind the breastbone but may also be felt in the jaw, neck, arms, back, or upper abdomen. Some people may also have difficulty in breathing or may become pale and sweaty. Symptoms of angina usually appear during physical exertion, after heavy meals, and with heightened emotional states, such as anger, frustration, shock, and excitement.

Atherosclerosis
Atherosclerosis, or hardening of the arteries, is a very common disease of the major blood vessels. It is characterized by fatty streaks along the vessel walls and by deposits of cholesterol and calcium. Atherosclerosis of arteries supplying the heart is called coronary artery disease. It can restrict the flow of blood to the heart, which often triggers heart attacks—the leading cause of death in Americans and Europeans. Atherosclerosis of the arteries supplying the legs causes a condition called intermittent claudication.
People with elevated cholesterol levels are much more likely to have atherosclerosis than people with low cholesterol levels. Many important nutritional approaches to protecting against atherosclerosis are aimed at lowering serum cholesterol levels.
