Constipation
Constipation is a condition in which a person experiences a change in normal bowel habits, characterized by a decrease in frequency and/or passage of hard, dry stools. Constipation can also refer to difficult defecation or to sluggish action of the bowels. The most common cause of constipation is probably dietary, which is discussed below. However, constipation may be a component of irritable bowel syndrome or other conditions ranging from drug side effects to physical immobility. Serious diseases, including colon cancer, may sometimes first appear as bowel blockage leading to acute constipation. However, constipation itself does not appear to increase the risk of colon cancer, contrary to popular opinion.
What are the symptoms of constipation?
Symptoms of constipation include infrequent stools, hard stools, and excessive straining to move the bowels. Frequency of bowel movements and severity of symptoms may vary from person to person.

Epilepsy
Epilepsy is a brain disorder in which abnormal bursts of electrical activity occur in cells of the brain, resulting in seizures. There are many types of epilepsy, usually categorized by the symptoms that occur during seizures. The cause of many types of epilepsy is unknown, and frequently no cure is available. Rather, treatment focuses on reducing the frequency and severity of seizures.
What are the symptoms of epilepsy?
There are many types of seizures in epilepsy. They are categorized as either partial or generalized, depending on how much of the brain is involved. Some types of epilepsy involve seizures characterized by convulsive muscle contractions of all or some parts of the body. Other types can involve momentary loss of consciousness, amnesia, unusual sensations or emotions, and other symptoms. Symptoms that indicate an imminent seizure (called auras) may occur. Similarly, non-convulsive symptoms, including deep sleep, headache, confusion, and muscle soreness (called a postictal state), may follow a generalized seizure.

Chronic Obstructive Pulmonary Disease
Chronic obstructive pulmonary disease (COPD) refers to the combination of chronic bronchitis and emphysema, resulting in obstruction of airways. Although chronic bronchitis and emphysema are distinct conditions, smokers and former smokers often have aspects of both. In chronic bronchitis, the linings of the bronchial tubes are inflamed and thickened, leading to a chronic, mucus-producing cough and shortness of breath. In emphysema, the alveoli (tiny air sacs in the lungs) are damaged, also leading to shortness of breath. COPD is generally irreversible and may even be fatal.
What are the symptoms of COPD?
Symptoms of COPD develop gradually and may initially include shortness of breath during exertion, wheezing especially when exhaling, and frequent coughing that produces variable amounts of mucus. In more advanced stages, people may experience rapid changes in the ability to breathe, shortness of breath at rest, fatigue, depression, memory problems, confusion, and frequent waking during sleep.

Wilson's Disease
Wilson’s disease is a genetic disorder that results in excessive accumulation of copper in many parts of the body, particularly the liver. This condition is readily treatable, but if Wilson’s disease is left untreated, it can be fatal.
What are the symptoms of Wilson’s disease?
Wilson’s disease is initially silent and may first be noticed as fatigue, absent menstrual periods in premenopausal women, or repeated and unexplained spontaneous abortions. In more advanced stages, there may be headaches, tremors, uncoordinated limb movements, unsteady gait, drooling, difficulty swallowing, and joint pain. There also may also be strange thought patterns with unusual behaviors.

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.
People with diabetes are also at very high risk for atherosclerosis, as are people with elevated triglycerides and high homocysteine.
